Shannon^s note says, "a shrub, rather a vinelike shrub. I 

 believe is a vine that grows generally near another (plant) and 

 overtops the companions. Plant 6o'™-2. l" high." 



Leaves pinnately veined, veins fourteen to sixteen, cov- 

 ered with extremely few hairs on both sides, rather more along 

 the midrib. Some of the leaves turning red, at least in her- 

 barium specimens. Inflorcscence remarkable for its numer- 

 ous white bracts, which has suggested the specific name of 

 leiccocepJiala, Very few of the cyathia have female flowers. 

 Dried styles persistenton top of capsule. Seeds, not entirely 

 ripe, with a dried funiculus, which suggests sometimes a 

 small shriveled carunculus. Blade of lower leaves 6-8*''" long, 

 at broadest place about 3. 5'"' wide. Petiole 2-2. 5'^" long. Ter- 

 nate leaves S-^'"" long, at broadest place i.5-2'™wide. Bracts 

 l-l.g*^'" long. Capsule about 0.5'"" long and'equally broad.
