Mesophyllum (Corallinaceae, Rhodophyta) is represented in southern Australia by at least four species. M. engelhartii and M. incisum have been reported from the region previously, M. macroblastum is newly recorded, and M. printzianum is newly described. Detailed accounts are provided for each species along with information on etymology, nomenclature and synonymy, collections examined, infraspecific taxonomy, and distribution, seasonality and habitat. Comparisons of southern Australian species with the type species of Mesophyllum, M. lichenoides, also are included. Of the nine additional entities that have been recorded from southern Australia under the generic name Mesophyllum, three (M. fumigatum, M. lemniscatum, M. versicolor) are considered heterotypic synonyms of M. engelhartii, three are referable to other genera of Corallinaceae (M. gabrielii to Lithothamnion; M. patena to Synarthrophyton; M. rupestre to Hydrolithon), two (M. lichenoides, M. neglectum) are based on misidentifications or questionable records, and one (M. squamuliforme) is treated as a species of uncertain status. Southern Australian specimens previously referred to Clathromorphum have been found to belong to Mesophyllum. As a prelude to the taxonomic accounts, a short historical introduction is provided along with a brief consideration of general morphological and anatomical features of Mesophyllum and a detailed analysis of characters that have been or could be used to delimit species within the genus. None of the at least 26 characters used by previous authors or the 34 quantitative characters examined during the present study were found to be of diagnostic value. By contrast, qualitative characters associated with tetrasporangial / bisporangial conceptacle roof morphology and anatomy have provided a reliable basis for delimiting the four southern Australian species from one another and from the type species of the genus, M. lichenoides. Concluding remarks, acknowledgments and references follow the taxonomic accounts.

Infraspecific Taxonomy

Lithothamnion (Corallinaceae, Rhodophyta) is represented in southern Australia by at least two species: L. muelleri, the type species of the genus, and L. indicum. Detailed accounts are provided along with a key to the species, and information on distribution, seasonality and habitat, nomenclature and synonymy, and infraspecific taxonomy. Two characters associated with tetrasporangial conceptacle roof anatomy are considered diagnostic of the two southern Australian species. Twenty-five characters used by other authors to separate species of Lithothamnion were examined; none were found to be diagnostic of L. muelleri or L. indicum, and only one (plant habit) was sometimes found to be useful as an ancillary character. None of the measured characters assessed could be used in a diagnostic or ancillary manner. The status and disposition of 22 other specific and infraspecific taxa ascribed to Lithothamnion and reported from southern Australia are summarised; 3 are considered synonyms of L. indicum or L. muelleri, 12 are referable to other genera, 6 are considered to be of uncertain status, and 1 constitutes an unconfirmed record.

The genus Xylaplothrips is re-diagnosed, 11 species are listed as appropriately included in this genus of which three are new combinations from Haplothrips (X. acaciae; X. collyerae; X. gahniae). A further six species are listed as incertae sedis within Xylaplothrips and a key is provided to the four species of this genus known from Australia including X. anarsius sp.n. The genus Mesandrothrips is recalled from synonymy with Xylaplothrips, and a list is provided of 20 appropriately included species of which 14 are new combinations from Xylaplothrips (M. caliginosus; M. clavipes; M. darci; M. dubius; M. emineus; M. flavitibia; M. flavus; M. inquilinus; M. montanus; M. pictipes; M. pusillus; M. reedi; M. subterraneus; M. tener), and one is a new combination from Haplothrips (M. inquinatus). A key is provided to 10 species of this genus known from Australia, including three species transferred from Haplothrips, together with M. austrosteensia sp.n., M. googongi sp.n., M. kurandae sp.n., M. lamingtoni sp.n. and M. oleariae sp.n. The type species, M. inquilinus, is widespread across Southeast Asia as an invader of thrips galls, and Haplothrips darci Girault based on a single female from Queensland is considered closely related.

Original Type

Abstract Type material for Stenopora tasmaniensis Lonsdale, 1844 was lost in the late nineteenth century, and subsequent descriptions of the genus have been based on material incorrectly assigned to the type species. A neotype is erected for S. tasmaniensis from the original type locality and the genus redescribed. The genus exhibits ramose, frondescent, encrusting, and massive colony morphologies, diaphragms are absent, and acanthostyles of a single size surround each aperture. This single size of acanthostyles aligns with the original type species description; however, it differs from the subsequently accepted genus description and may result in existing species being removed from the genus. Analysis of zooecial characters of a single colony exhibiting both frondescent and ramose morphologies reveals statistically significant differences between subsampled sections, despite being from the same colony. Differences relate to details of zooecial parameters and are not controlled by colony morphology. This variation within a single colony confirms the importance of using qualitative characters alongside quantitative measures in defining Paleozoic bryozoan species.

<span style="font-family: Times New Roman; font-size: small;"> </span><p>Wood anatomy of five <em>Cola</em> species was investigated to identify and describe anatomical features in search of distinctive characters that could possibly be used in the resolution of their taxonomy. Transverse, tangential and radial longitudinal sections and macerated samples were prepared into microscopic slides. Characteristic similarity and disparity in the tissues arrangement as well as cell inclusions were noted for description and delimitation. All the five <em>Cola</em> species studied had essentially the same anatomical features, but the difficulty posed by the identification of <em>Cola acuminata </em>and <em>Cola nitida</em> when not in fruit could be resolved using anatomical features. <em>Cola acuminata</em> have extensive fibre and numerous crystals relative to <em>Cola nitida</em>,<em> </em>while<em> Cola hispida </em>and <em>Cola millenii</em> are the only species having monohydric crystals. <em>Cola gigantica </em>is the only species that have few xylem fibres while other species have extensive xylem fibre. These features have proved very functional and strongly of diagnostic value in the classification and delimitation of the studied <em>Cola </em>species.</p><span style="font-family: Times New Roman; font-size: small;"> </span>

Previously Treated

Based on examination of type species, the subgenera Palaeoconnus Franz and Heterotetramelus Franz are removed from Euconnus Thomson. Adults of Palaeoconnus have the prosternum bearing a subtriangular prosternal process and their metacoxae are contiguous, which exclude this taxon from Euconnus. Palaeoconnus is transferred to Sciacharis Broun as subgenus and redefined. The lectotype is designated for its type species, Scydmaenus brevipes Sharp. Sciacharis andicola (Franz), previously treated as incertae sedis within Sciacharis, is placed in Palaeoconnus. Heterotetramelus is also excluded from Euconnus, on the basis of the mesoventrite lacking the mesoventral intercoxal process and the contiguous metacoxae. Heterotetramelus stat. n. is elevated to genus rank and redefined, and the lectotype is designated for its type species, Euconnus caledonicus Franz. Moreover, the newly defined Heterotetramelus is reclassified to include four subgenera: Heterotetramelus s. str. (with seven species distributed in New Caledonia), Sciacharoides Jałoszyński, stat. n. (reduced from genus; with three Australian species); Australosciacharoides subgen. n. (with only one Australian species transferred from Sciacharoides); and Tamborinus subgen. n. (also with one Australian species transferred from Sciacharoides).

Available Information

The root, rhizome, petiole and blade anatomy of Ctenitis melanosticta was studied and compared with the available information for closely related genera. Root is diarc with sclerenchyma and parenchyma cells in the cortex, with fungal hyphae exclusively in the latter. The occurrence of sclereid nests in the rhizome is shared with Dryopteris and Campyloneurum. A cortical band was present in petiole and lamina, as in Dryopteris and other genera of the most derived ferns. The lamina had unifacial mesophyll and under the adaxial epidermis there were several layers of the fiber, as described for Elaphoglossum and Thelypteris, but differed from Asplenium, Dryopteris, and Polybotrya with collenchyma. The anatomy of C. melanosticta was similar to that of most species studied of Dryopteridaceae, although with some differences. Additional anatomical studies in species of Dryopteridaceae will allow to confirm the diagnostic value of several anatomical features, such as the lack of cortical band in the rhizome, the sclereid nests, the unifacial mesophyll, and the cortical band in the lamina.

Two New Species

The Australian species of the small heterogastrid genus Parathyginus Scudder, 1957 have been reviewed, resulting in the establishment of the junior subjective synonymy of P. doddi (Distant, 1918) with P. signifer (Walker, 1872), and the description of two new species, P. australis sp. nov. and P. acuminatus sp. nov. A redescription of the genus is provided with emphasis on male and female genitalia characters, along with a key to all included Australian species. Male genitalia, particularly the details of the aedeagus, have been rarely studied in this genus or for that matter the family Heterogastridae particularly due to the difficulty in inflating the inflatable sections. In this study, therefore, an attempt was made to fully inflate and describe the aedeagus of all the species included in this contribution, as well as of Heterogaster urticae (Fabricius, 1775), the type species of the oldest genus Heterogaster Schilling, 1829, of the family Heterogastridae.

Plumbago is a traditional medicinal plant in Ayurveda. The paper presents anatomical study of leaf, petiole, stem and root of two species of Plumbago namely P. zeylanica, P. auriculata and, its relevance in discrimination of these two species. Anatomical features of leaf which are of diagnostic value in delimitation of both taxa are outline of T. S.,shape and size of epidermal cells, presence of sclerenchyma surrounding the vascular bundles, number of tannins cells. Characters of taxonomic significance in petiole anatomy are outline of T. S, presence of trichomes, shape and size of epidermal cells, abundance of collenchyma, arrangement and number of vascular bundles, presence of sclerenchyma surrounding vascular bundles, number of tannin cells. The diagnostically useful anatomical features of stem to discriminate both taxa of Plumbago are degree of elevation of stem ridges, occurrence of double layered epidermis, size of epidermal cells, distinctness of endodermis, abundance and distribution of pericyclicsclerenchyama, number of vascular bundles. Anatomical features of taxonomic significance in root are width of cortex and abundance of starch grains in cortex cells, abundance and distribution of pericyclics clerenchyama, amount of vascularization, distribution, diameter and density of vessels, width of medullary ray.

The phylogenetic relationships of the Australian scincid lizards currently assigned to the genus Leiolopisma have been examined by quantitative micro-complement fixation (MC'F) comparisons of serum albumin. The results of these comparisons do not support the monophyly implicit in these species' current congeneric status, but suggest instead that the Australian species of Leiolopisma belong to several distinct phyletic lineages within the Eugongylus group. These findings are supported by several sets of non-biochemical characters, including features of scalation, osteology and karyotype. None of the Australian species shares a close relationship with the type-species of Leiolopisrna (L. telfairii), and so a new taxonomic arrangement is proposed which distributes them among the following genera: Bartleia, gen. nov. (jigurru); Bassiana, gen. nov. (duperreyi, platynotum and trilineata); Cautula, gen. nov. (zia); Niveoscincus, gen. nov. (coventryi, greeni, metallicus, microlepidotus, ocellatus, orocryptus, palfreymani and pretiosus); and Pseudemoia Fuhn, 1967 (baudini, entrecasteauxii Group 1; entrecasteauxii Group 2, rawlinsoni and spenceri). Preliminary comparisons suggest that other Leiolopisma species, from New Caledonia, Lord Howe I. and New Zealand, belong to phyletic lineages which are distinct from any of the Australian 'Leiolopisma' and from the type-species.

Qualitative Characters

Seventy-three samples of wood, belonging to 11 genera of Loganiaceae and 2 genera of Rubiaceae are described. Fourteen quantitative characters are first studied by a discriminant multivariate analysis, and then all the characters are examined. The characters of wood anatomy show the unity as well as the subdivisions of the family Loganiaceae. The two genera Antonia and Bonyunia belong to an homogenous and individualized group. Potalia, Anthocleista, and Fagraea are also related and are opposite to Strychnos. Neuburgia is not near Strychnos, though it belongs to the same tribe. A new relation is discovered between Nuxia and Geniostoma, and the special feature of Buddlejeae (Nuxia, Buddleja) does not come into sight; these genera are also related to Strychnos and Peltanthera. The genera Gaertnera and Genipa can scarcely be distinguished from the family by a few qualitative characters. The necessity of standardization in the observations, in order to integrate wood characters in systematic studies, is noted.
