A morphological and cytological study of native and introduced Lotus species found in Canada has been conducted on both living material and on over 600 herbarium specimens from 20 Canadian and American herbaria. Illustrations of flowers, seed, ovaries and styles, habit, and geographical distribution for each species are given. Five native species, L. denticulatus (E. Drew) Greene (annual (A), self-fertilized (S), 2n = 12), L. formosissimus Greene (perennial (P), outcrossing (O), 2n = 14), L. micranthus Benth. (A, S, 2n = 14), L. pinnatus Hook. (P, O, 2n = 14), and L. purshianus (Benth.) Clem. and Clem. (A, S, 2n = 14), and four introduced species, L. corniculatus L. (P, O, 2n = 24), L. krylovii Schischk. and Serg. (A, S, 2n = 12), L. pedunculatus Cav. (P, O, 2n = 12), and L. tenuis Waldst. et Kit. (P, O, 2n = 12) were found in Canada. Chromosome numbers are reported for the first time for L. formosissimus, L. micranthus, and L. pinnatus. Drawings of karyotypes and idiograms based on chromosome analyses are presented. Morphological observations made include style shape, pollen size and shape, seed size, number of flowers, length of standard, calyx index (length of calyx/length of calyx tube), length of peduncle, length of legume, length of petiole, and central leaflet index (leaflet length/leaflet width). Results of hydrocyanide tests on leaves of the native species were negative. The relationships of the different taxa are discussed and it is considered that both the North American and Old World species should be included in a single genus Lotus.

Morphological boundaries between South American species of Euphrasia L. are controversial, rendering determination of specimens an arduous task. In this context, a comprehensive taxonomic revision of Euphrasia in South America is here provided for the first time. This study, based upon a classical morphological study of ca. 400 herbarium specimens, supports the recognition of eight species and one subspecies distributed in the Andean regions of Argentina, Bolivia, and Chile. From among native species, six belong to section Trifidae Benth. and one to the monotypic section Paradoxae Pugsley, endemic to Juan Fernández Islands; one adventive species, E. officinalis L., belongs to the section Euphrasia. The previously misunderstood presence of E. cockayniana Petrie is here untangled, and, consequently, the species is excluded from South America. A key to all Euphrasia taxa in South America, plus morphological descriptions, nomenclature items, geographical distribution and maps, habitat notes, illustrations, photographs, and discussion notes are included for the nine taxa. Eleven names are here synonymized, and lectotypes are designated for E. andicola Benth., E. debilis Wettst., E. flavicans Phil., E. intricata Phil., and E. philippii Wettst. Euphrasia andicola is reported for the first time for Argentina. This collaborative effort will represent a baseline for further investigations on Euphrasia in South America.

Solidago ×niederederi Khek (1905: 22) is a hybrid between North-American S. canadensis Linnaeus (1753: 878) and European native S. virgaurea Linnaeus (1753: 880). Solidago canadensis was introduced to Europe in the 17th century (Kowarik 2003). It has spread invasively throughout Europe since the second half of the 19th century (Weber 1998), reaching, besides sites disturbed by human activity, also (semi)natural biotopes, as forest edges, abandoned meadows and field margins which are often inhabited by native S. virgaurea. Their hybrid was discovered for the first time in nature by a local schoolmaster Franz Niedereder in the area of Vorderstoder village (Austria). Niedereder sent a plant material of the assumed hybrid to Eugen Johan Khek (born in 1861, Neuhaus/Jindřichov Hradec; died in 1927, Vienna), the pharmacist and botanist who lived in Vienna since 1889 (Anonymous 1916). Khek described the hybrid species under the name S. ×niederederi in honour of his discoverer (Khek 1905). The protologue indicates that the relevant communication between Niedereder and Khek was going on between July 1900 (when they met for the first time) and February 1905 (when the hybrid’s description was published). Before its description, Khek studied the hybrid for four years and he saw a herbarium material from Niedereder as well as a living material. In the protologue, no particular herbarium specimens or illustrations had been indicated or associated with S. ×niederederi (Khek 1905).

A cytological study was conducted on the freshwater red alga Audouinella hermannii (Roth) Duby (Acrochaetiales) from the North Alouette River, British Columbia. Cell division and elongation occurred exclusively in apical cells of the primary axis, branches, and branchlets; new cell wall material was produced at the tip of the cells. Six chromosomes were counted in vegetative cells. The fine structure of vegetative cells was similar to that of the few other florideophycean algae studied to date. Ultrastructure of apoplastic hair cell development was recorded for the first time in the Rhodophyta. Mature hair cells were long and characterized by a thin wall, a large proximal vacuole, and cytoplasm concentrated at the distal end containing a large central nucleus, active dictyosomes, and an abundance of endoplasmic reticulum, and mitochondria.

AbstractTwo species of the genus Posthodiplostomum (Digenea: Diplostomatidae) (Posthodiplostomum brevicaudatum Nordmann, 1832 and Posthodiplostomum cuticola Nordmann, 1832) are known as parasites of Hungarian native fishes. Metacercariae of P. cuticola are widespread in Europe and cause black spot disease. Several species of Posthodiplostomum were described also from North America but none of them has been isolated in Hungary up to now. Posthodiplostomum centrarchi Hoffman, 1958 has been detected recently in pumpkinseeds (Lepomis gibbosus L., 1758) in several European countries. Posthodiplostomum centrarchi was isolated for the first time in Hungary from pumpkinseeds caught in the Maconka water reservoir in 2015. Thereafter, several natural waters (e.g. the River Danube, Lake Balaton and the Sió channel) were sampled in order to determine its presence and distribution. Only the native species P. cuticola was detected in Lake Balaton on cyprinids but a relatively high infection rate of P. centrarchi was observed in the Sió channel close to the lake. Pathological changes were absent, and metacercariae were mostly attached to the surface of the liver, kidney and heart. The phylogenetic analysis of the ITS and COI sequences of P. centrarchi and P. cuticola clustered into two distinct branches, which was in agreement with the morphological results.

A taxonomic revision of all native Myrtaceae genera (Eugenia and Syzygium) of the Comoros is presented based on herbarium specimens and molecular and palynological evidence. Eight native species are recognised, seven of which are endemic to the archipelago. We describe the following five new native species: Eugenia choungiensis, E. pascaliana, Syzygium comorense, S. labatii, and S. tringiense. Eugenia anjouanensis is reduced to synonymy under E. comorensis. Lobed stigmas are reported for the first time in Eugenia and only the second time in Myrtaceae. Androdioecy is reported in Eugenia for the first time outside of continental Africa, and its reproductive system is discussed in light of our findings. Preliminary conservation assessments for each native species are calculated according to IUCN Red List criteria, with the majority being threatened with extinction. Recent fieldwork coupled with widespread habitat conversion in the vicinity of the only known specimen suggests strongly that S. humblotii is now extinct.

Data obtained from licenses of spearfishers and surveys conducted in 2004 and 2017 allowed for the analysis, for the first time, of the practice of spearfishing in the Madeira archipelago. Only a small percentage of the population practices spearfishing, mostly local young men. Most of them practice the activity with a partner throughout most of the year and along most of the island's coastal areas, although preferentially along the North and Southeast coast. Results show how, in recent years, despite the population of spearfishers decreasing, the abundance in the annual catch potentially increased, probably due to the higher investment of time in this activity. It has been observed that many fishers complement their catches with manual collecting of invertebrates. Overall, 40 teleost fishes and also 4 crustaceans and 8 molluscs were identified. The most frequently captured fish species were parrotfish and white seabream, while limpets were the most collected invertebrates in both selected periods.

Sphagnum mires on the Greater Caucasus are rare, characterized by the presence of relict plant communities of glacial age and are in a stage of degradation. The study of Sphagnum of Chefandzar and Masota mires is carried out for the first time. Seven species of Sphagnum are recorded. Their distribution and frequency within the North Caucasus are analyzed. Sphagnum contortum, S. platyphyllum, S. russowii, S. squarrosum are recorded for the first time for the study area and for the flora of North Ossetia. The other mosses found in the study area are listed.
