TRIANDRIA. MONOGYNIA. 25 



pedicellate beyond the spathe; (laminse in seve- 

 ral species aristate.) 



Root fibrous; stem compressed, ancipital, divided; flow- 

 ers both terminal and axillary; spatha many-flowered, 

 compressed-carinate. Flowers white, yellow, or blue. 



Species. 1. miicronatinn. 2. anceps. o. Bennndianion? 



Obs. Of 9 species now enumerated, 4 inhabit the tropi- 

 cal regions of America, (Peru, Guiana, and the West- 

 Indies) having white and yello.w flowers; 3 belong" to the 

 United States, producing blue flowers with aristate petals; 

 X with yellow flowers to the Cape of Good Hope, and 

 another of a doubtful genus, resembling Ixla^ was dis- 

 covered by Forster in New Zealand. 



56. BOERHAATIA. L. 



w 



Calix tubulose with an entire margin. Co- 

 rolla mon(>petah)us, campanulate, plaited. Seed 

 1, invested by the persistent calix, naked or tu- 

 berculate, 5-furro\ved, obconic. (^Stamina 1, 2, 

 S, 4, and 10.) 



Stems herbaceous or shrubby, leaves opposite, one of 

 the leaves often less than the other; flowers mostly um- 

 bellate; umbels slender, axillary, pedunculate, some- 

 times branching, involucrate; involucrum simple, or many- 

 leaved; flowers also, in some species, disposed in corym- 

 bose panicles. (Jussieu says, that the seed is small, and 

 covered by the angular bane of the calix ^ and in this he is 

 confirmed by the observations of Defontaines; but to or- 

 dinary observers the seed will be considered as interior. 

 The same remai'k also applies to the folio wmg genus, 

 Cahimenia.') 



Species. 1. erecta. (South Carolina.) 2. diffusa? 



Obs. This genus is ciiiefly confined to the tropical re-
