    • Nodal anatomy in Trifolieae

      Mohini Gupta Y S Murty

      More Details Abstract Fulltext PDF

      A trilacunar, three traced stipulate node is observed in 36 species studied representing all the six genera of Trifolieae. Most of the species ofTrifolium agree in the splitting of the median at the base into three, in the presence of five bundles at the base of the petiole and in their formation. Thus they appear to be distinct from others.

      Trichomes of nine species belonging to four genera have been studied. Organographic distribution of each type is given. Ontogeny of one more type has been worked out.

      More Details Abstract Fulltext PDF

      Structure of the trichomes occurring on floral parts is described in eighteen species ofCrotalaria. On the basis of structure they are classified into 9 types of which ontogeny of four types has been studied. Organographic distribution of each type is given. The four hair types of which ontogeny was studied, all develop from a single initial cell. Most of the hairs can be used for specific delineation although they show less variations. A key for the identification of the species on the basis of the trichomes studied is given.

      More Details Abstract Fulltext PDF

      Petal venation of nine species ofTrigonella has been worked out. A positive correlation has been found between length or area and the number of dichotomies but no correlation is found with breadth. In all the species corolla is of simple type exceptT. polycerata in which it is of medicagoid type. Among the different types of anastomosesC andD types are of most frequent occurrence and other types are species specific with a low range of variation.
