The secondary stigma or biglandular swelling occurs just below 

 the normal stigma, at the level of the anthers, and is almost con- 

 fluent with it. 



Sebcea ecarinata, A. W. Hill (sect. Tetrandria), is nearly allied to 

 S. albens, E. Br., in the absence of keel or wing to the calyx seg- 

 ments. It differs from this species in being much more slender with 

 few-flowered terminal inflorescences. The calyx segments differ in 

 being usually truncate, notched, or fringed, and the flowers are 

 smaller in all their parts.

Sebcea membranacea, A. W. Hill (sect. Pentandria-Lageniades), is 

 an interesting species most nearly allied to S. jmsilla, Eckl., with its 

 var. major, A. W. Hill. It is distinguished by being the largest 

 species of the group, reaching a height of 6 in., with several branches 

 from near the base of the stem. It differs from its allies in having 

 the membranous, acuminate calyx segments united to form a tube 

 for f lin. The anthers are f lin. long with large basal glands, and 

 the style is only ^— f lin. long, being smaller than in S. pusilla.
