A study of the non-articulated laticifers and the nature of latex in two members of asclepiadaceae

The non-articulated, very little branched, simple type of laticifers inLeptadenia reticulata originate at the embryonic stage of the plant. These later on grow and develop into the other organs and form a well distributed system of laticifers, in the stem and also in the leaves, near the veins and veinlets. A qualitative chemical analysis of the latex ofLeptadenia reticulata and alsoCryptostegia grandiflora, another member of the Asclepiadaceae, has revealed the presence of various kinds of enzymes, sugars and amino-acids in the latex. These, probably, are of some importance to the plant.
