 narrowly canaliculated in front, l|-6^cm. long, thinly white- 

 tomentose when young but soon glabrous ; stipules free or 

 shortly adnate at the base, falcato-linear, linear-lanceolate or

subcordate at the base, cuspid ato-acute or acuminate at the apex, 

 serrulate with sharply pointed teeth, often 3- parted or fid ; the

 cuspidate, ciliated, glabrous or adpressed-pubescent on the back ; 

 outer ones depressed-ovate ; the middle oval ; the inner ovato- 

 elliptical, about 5mm. long. Flower-clusters terminal, racemoso- 

 umbellate, about 3-11-flowered ; common rachis very short,

 1^— 2^cm. across, w^hite. Cal3^x viridescent, 8— 11mm. across,

 the carpels, depressed-obconical, glabrous internally, tomentose 

 externally, slightU^ shorter or longer than the segments ; the 

 lower portion adnate to the carpels, globoso-ellipsoid, white- 

 tomentose, about l^limm. in diameter. Fetals 5, inserted at
