In the present investigation vessels of 16 species of family Asclepiadaceae have been studied. Through a lot of variation exists in the size and shape of vessels, number of perforation plates and intravascular thickening of walls in the taxa, the vessels in asclepiadaceae are found highly specified.

Pollinarium removal and pollinium insertion of seven Oxypetalum species (O. alpinum var. alpinum, O. appendiculatum, O. banksii subsp. banksii, O. jacobinae, O. mexiae, O. pachyglossum and O. subriparium) were recorded in Viçosa.

The macroscopic and microscopic characters, physical constant values, extractive values, ash values the behaviour of the powerdered drug on treatment with different chemical reagents, microchemical ad histochemical analyses were conducted to characterize some pharmacognostical parameters of Hemidesmus indicus (Linn) R,Br. (Asclepiadaceae).
