IllusteatioN. — The young specimen of Hyoioliorhe Verscha- 

 ffeltii, figured on plate LX, is growing in Mr. Millard's garden 

 on Malabar Hill, Bombay. The owner was kind enough to 

 supply the photograph. The stem is distinctly triangular,. and as 

 to the leaves, it is not difficult to find out the differences as 

 regards number, size, shape and structure, which distinguish this 

 species from IIyo]jhorhe amaricaulis.

 cavities, monoecious in clusters of 3, the male pair behind the female 

 flower, the upper part of the branches bearing only male flowers. 

 Male flowers : often oblique ; calj^x small, imbricate ; corolla large, 

 valvate; stamens 6-8. Female flowers: calyx and corolla imbricate 

 (exceptions sub A in the following key : corolla valvate). Ovary 

 of 3 completely united carpels, always 1-locular with one seed 

 by the abortion of 2 seeds, but with 3 apical stigmas.
