Chromosome studies in some Stevia. Cav. (Compositae) species from Southern Brazil

In the same series of samples, some specimens of Octophialucium bigelowi Kramp 1955 were taken which are very similar to Octocanna haeckeli but have eight

The follow- ing ~omments may be made on the present material: cephalon abruptly convex; cephalic posterior groove always well marked; dorso lateral sides of

xiru from all others species of the genus (including the species complex A. scabripinnis): the presence of two conspicuous humeral spots (first humeral spot vertically elongate

(Figs 8, 9) four segmented, with fused femur-genu bearing three dorsal robust needle-like setae, distal one longer as proximal ones; tibia with six robust setae, three dorsal

the family Phyllostomidae have been studied by Ag-NOR staining (Baker, 1979). In the specific case of Phyllostomus , NOR studies are needed to verify if: 1) P. stenops present

Since the Euro- pean species are likely ancestors of the South American species, we suggest that the differences in satellite posi- tion and chromosome shape arose by

also share the chromosome number (2 n = 46) and the gen- eral karyotype features, which, together with previous cyto- genetic data for those genera (Martínez, 1985; Dematteis

2 n = 42 (Figures 1c, 3b), with three large chromosome pairs and additional smaller pairs, the karyotypic formula was 38M+2SM+2A, the chromosomes measured 1.29-6.51 m m, and
