Three populations of Cyperus tenuispica Steud. belonging to family Cyperaceae were collected from different localities of North India. The meiotic behavior, chromosome number, morphological analysis and pollen fertility were studied. The investigations revealed the existence of two cytotypes with n=8 in two populations and with n=7 in one population. Basic chromosome number of the Cyperus is n=8 and C. tenuispica shows same chromosome number. The plants of the population with n=7 is an aneuploid. The population with aneuploid chromosome number n=7 showed abnormal meiosis i.e., chromatin bridges, laggards, stickiness, and reduced pollen fertility. Three populations exhibit a difference in plant height, length of leaves, number of rays, number of spikelets and number of glumes per spikelet.

“…Darlington and Wylie (1955) suggested the basic numbers of x=8, 9 and 60 for Cyperus and 23 for Lip ocarpha. Subsequently, Rath and Patnaik (1974) added one more basic number of x=13 for both Cyperus and Lipocarpha. Of 16 species of Cyperus studied during present investiga tion, six conform to the basic number of 8, three fit into the basic number of 9 and the remainder to the new basic numbers such as x=5, 11, 19 and 29.…”

“…Sharma and Bal (1956) were the first to study the cytology of Indian species of the Cyperaceae. Since then, several Indian species were investigated by various workers (Mehra and Sachdeva 1975, 1976, 1979, Nijalingappa 1973-1975, 1977, Rath and Patnaik 1974, Sanyal 1972and Sanyal and Sharma 1972. Patnaik and Rath (1983) have discussed the chromosomal evolution in the family by critically analysing the available cytological data.…”

Chromosome Counts of Some Wetland Cyperaceous Species from the Mekong Delta, Vietnam

Summary Chromosome numbers were counted in root tip cells of 6 cyperaceous species growing in wetlands in the Mekong Delta, Vietnam. The results were as follows: Cyperus haspan, 2nϭ26; Eleocharis dulcis, 2nϭca. 212; Eleocharis spiralis, 2nϭ42; Fimbristylis ferruginea, 2nϭ20; Fimbristylis polytrichoides, 2nϭ10; Lepironia articulata, 2nϭ34. They were reported here for the first time using plant materials from Vietnam. Furthermore, the results of 2 species, Eleocharis spiralis and Lepironia articulata, were the first to be reported for these species. In addition, the dimorphism of Eleocharis dulcis shoots representing emerged and submerged culms was recorded.
