1895. ] Euphorbiacee from Guatemala. 351 
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 60™—2.1™ 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. Inflorescence remarkable for its numer- 
ous white bracts, which has suggested the specific name of 
leucocephala. Very few of the cyathia have female flowers. 
Dried styles persistent on 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 3-4™ long, at broadest place 1.5—2™ wide. Bracts 
I-1.5™ long. Capsule about 0.5™ long and equally broad.
