Determinations of chromosome number and morphological studies of 260 populations, belonging to 32 taxa, of the genus Brachiaria from the Indian subcontinent reveal that all sexually reproducing taxa have no chromosome races. Six agamic taxa, viz., B.

Arundinella mesophylla n=8 andA. purpurea n=10 of the Poaceae, endemic species of South India are studied for their mode of reproduction. Meiosis in microsporocytes of these two diploid taxa is regular and produces normal spore tetrads. Development a

An abundance of circumstantial evidence has led earlier workers to believe that apomixis was a common phenomenon in North American Crataegus. However, direct proof was lacking. In this paper, working with accessions of Crataegus pruinosa (Wendl.) K.

This paper records the occurrence of diplospory for the first time in the genus Crataegus L. (Rosaceae). It occurs in C. dissona Sarg., a scarce triploid (2n = 51) of the Great Lakes – New England region. Proof of diplospory is derived from the som
