Abstract
The present meiotic study was carried out in 15 species of medicinal importance belonging to 14 genera and nine families. The chromosome numbers n=7 of Aloe vera L., n=10 of Brassica campestris Hook.f. & Thoms, n=12 of Capsicum annuum L., n=12 of Cissampelos pareira L., n=10 of Croton bonplandianum Baill., n=32 of Heliotropium eichwaldi Steud., n=7 of Hordeum vulgare L., n=7 of Lathyrus aphaca L., n=20 of Mazus rugosus Lour., n=7 of Pisum sativum L., n=6 of Sesbania sesban Merrill., n=12 of Solanum verbascifolium L., n=11 of Tephrosia purpurea Pers., n=6 of Vicia faba L. and n=6 of Vicia sativa L. has been observed. The course of meiosis has been found to be normal in all species except in somewhere chromosomal irregularities have also been observed.
