Numerical analysis of the taxa belonging to the genus Rosularia (DC.) Stapf was carried out to find out their phenetic relationship. Data from different disciplines viz. general, pollen and seed morphology, chemistry and distribution pattern were used. As a result of cluster analysis two distinct groups are formed. Out of which one group consists of R. sedoides (Decne.) H. Ohba and R. alpestris...
In phylogenetic trees the addition and removal of taxa has large effects on tree topology, hence measures of branch support and tree stability should account for taxonomic composition. Currently no comprehensive system of composition-dependent parameters exists in any cladistic or phenetic strategy. We introduce several values and indices based on a modification of the original jackknife resamp...
A series of 2277 Leishmania strains from Old World visceral leishmaniasis foci, isolated between 1973 and 2008, were studied by isoenzyme analysis. The strains were obtained from humans, domestic and wild carnivores, rodents and phlebotomine sandflies, and came from 36 countries. In all, 60 different zymodemes were identified and clustered by a phenetic analysis into 3 different groups correspo...
Solanum umalilaense Manoko sp. nov. (Solanaceae) is described from the Umalila area, in the southern highlands of Tanzania. Its novelty is supported with both morphological and AFLP data. Phenetic and phylogenetic analyses place Solanum umalilaense as a unique and well-supported taxon among tetraploid species of Solanum sect. Solanum from Africa. It can be distinguished from other African speci...
