and the two anterior segments are connected with the posterior 

 one ; in the pistillate flower they are free. All the segments are 

 bearded at the apex. Stamens six. Ovary stipitate, three- 

 celled ; style three-parted. The species is well distinguished from 

 E. dccangiilarc, to which it is similar in habit, by its six-parted 

 flowers. Hartweg collected this plant at Lagos, Mexico.

This genus closely resembles Eriocaidon in general appear- 

 ance and habit, but is distinguished by having the interior seg- 

 ments of the sterile flower campanulate-tubular, and the stamens 

 of the same number as the lobes. The flowers arc with rare ex- 

 ceptions three-parted throughout, the three stigmas often bifid. 

 Seeds oval, more or less costate. 



The genus is very extensively represented in South America, 

 being concentrated in Brazil. Kornicke in his monograph 

 enumerates 215 species. Only one is found in North America.
