in the last the corolla-tube is said to be glabrous and the month villous ; 

 the leaves are also described as much larger and broader. The corolla, 

 tube of I. frutescens, however, is usually pubescent. 



Chota Nagptir, Train. A spocimen from Jhirioi (Santara forest) may 

 he this, which! consider only a variety of I. frutescens. 



Fam. 75. ASCLEFIADACEE. 



Usually climbing shrubs or herbs, rarely erect. Differing 

 from the Apocvnacese chiefly in respect of the andrcecium. 

 The stamens are sometimes free, but more usually connate in- 

 to a fleshy column surrounding the pistil and generally bear 

 dorsal processes collectively termed the "staminal corona" 

 (to distinguish it from the scales or processes which are 

 sometimes present on the corolla and which are termed the 

 " coralline corona'''}. The pollen forms 1 or 2 masses 

 {pollinia) in each anther lobe, and these pollinia are united to 

 a gland (corpuscle) lying between the several anthers so that 

 the pollinium (or pollinia) of the left-hand lobe of one anther 

 is connected with the rjollinium (or pollinia) of the right-hand 

 lobe of the next anther. Carpels 2 distinct Styles united 

 in the e.tigma. Fruit normally of 2 follicles. Albumen 

 copious and embryo large.
