Numerical taxonomy and cladistic analysis of 19 species of Camellia L. were performed using floral morphology containing continuous and discrete units. The current study mostly supports the classifications of 19 species as proposed in previous works. In addition, it also agrees with combining the following species together: C. oleifera and C. vietnamensis; C. sasanqua and C. hiemalis; C. brevistyla and C. puniceiflora; and C. grijsii and C. shensiensis. Further, we propose that C. maliflora be recognized as a variety of C. sasanqua, and C. phaeoclada is best placed in sect. Paracamellia. Moreover, we conclude that these species can be combined: C. tenii and C. miyagii; and C. confusa and C. fluviatilis. Our study indicates that the numerical taxonomy and cladistic analysis based on morphological characters of floral organ is useful in species classification, and this technique appreciated in sect. Oleifera and sect. Paracamellia can be used for identification and classification of other taxa. DOI: http://dx.doi.org/10.3329/bjpt.v19i2.13130 Bangladesh J.

Important Character

Mallomonas is one of the biggest genera of Chrysophyta. In total, 37 species and 2 varieties have been recorded in China. Because of their narrow ecological optimum, species of this genus are considered as valuable bioindicators. However, taxonomy of Mallomonas remains unclear. We studied the numerical taxonomy of all the species and varieties recorded in China using Ward’s method and the furthest neighbor method based on 52 morphological characters. Shown in the phylogenetic trees, those species could be divided into two major clusters. One cluster includes 5 small clusters and another includes 2. The results of numerical taxonomy are partially consistent with the traditional ones with some divergences. Furthermore, the diversity of silicified scales including shapes and structures was confirmed as the most important character for identification of Mallomonas species.

Typhlodromus Caudiglans

Variation in morphological characters between Canadian populations of Typhlodromus caudiglans Schuster (Acarina: Phytoseiidae) was examined by the methods of numerical taxonomy. Western populations are separated from the other populations when multivariate tests are used. Two subspecies are proposed, and Typhlodromella nodosus De Leon is synonymized with Typhlodromus caudiglans. Morphological variations between northern and eastern populations are correlated with climatic variables and with host plants.

Using Data

Cluster analysis of hybridizing Lepomis gibbosus (pumpkinseedsl and L. macrochirus (bluegills)collecled in Lake Opinicon, Ontario, using data on 20 morphological characters in 108 specimens, revealed three groups, the two parental species and a group of hybrids, all of which were clearly separated by discriminant analysis. Discriminant functions based on the red opercular flap, the pharyngeal dentition, and body depth, correctly assigned all specimens to the appropriate group. Discriminant functions are also reported for external characters only, but the assignment to groups is not perfect. A sample of L. gibbosus, taken from a locality in which other Lepomis species were not present, was found to be very similar to the Lake Opinicon sample of this species. The hybrids of Lake Opinicon do not appear to backcross frequently with the parental species, possibly because of nonintermediacy in reproductive behavior.

Phenetic Analysis and Distribution of Claoxylon in the Lesser Sunda Islands. Floribunda 6(5): 167–174.  — The genus Claoxylon A.Juss. in the Lesser Sunda Islands (LSI) was reviewed. Eleven species were recognized in Lesser Sunda Islands. Records of C. capillipes and C. fulvescens were extended to the Bali Island. Based on distribution of Claoxylon in LSI, Bali has the highest number of species (7 species), while Wetar shows the least number of species (only 1 species). A phenetic analysis was using Numerical Taxonomy and Multivariate Analysis System (NTSYS-pc) version 2.11a and distribution mapping using Quantum GIS version 2.4. Based on 14 morphological characters grouped Claoxylon species in LSI into three groups. All Claoxylon in LSI belong to section Indica and Affinia.

Taxonomic Groups

The taxonomic history of the family Phytoseiidae is briefly reviewed. The taxonomic structure of the family is analysed using the methods of numerical taxonomy, with 221 morphological characters in 93 species covering the major taxonomic groups that have been proposed within the family. Both weighted and unweighted character analyses are used. It is shown that definite gaps separate groups of species within this family. At the level of major hierarchical separations both the unweighted and weighted character analyses are similar. A classification based on these major hierarchical separations is proposed. It is demonstrated that neither the classical system, based mainly on dorsal chaetotaxy, nor the numerical system alone provides a completely acceptable classification of the family, but that numerical taxonomic analyses are useful as a tool in helping to determine the hierarchical organization of the group.
