TRIANDRIA. MONOGTNIA. S5 



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. I. mucronatwn. 2. anceps. 3. BermiuUanxmi? 



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

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

 Indies) having white and yellow flowers; 3 belong to the 

 United States, producing blue flovv^ers with aristate petals; 

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

 another of a doubtful genus, resembling Ixia, was dis- 

 covered by Forster in New Zealand. 



56. BOERHAAVIA. L. 



Calix tubulose with an entire margin. Co* 

 rolla monopetaloiis, campanulate, plaited. Seed 

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

 berculate, 5-furrowed, 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 angulm- bas-e of the calix, and in tliis he is 

 confirmed by the observations of Defontaines; but to or- 

 dinary observers the seed will be considered as inferior. 

 The same remark also applies to the following genus, 

 Calymenia.) 



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



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

 gions of America, there is also 1 species in Guinea (Afri- 

 ca), 1 in Spain, 1 common to India and China, and another 

 in the Society islands of the Pacific. 



57. CALYMENIA. Persoon. (xVjllioxia. Mi- 



chaux,)

 enlargin,:^, and then peltate-campanulate, 1 to 

 3 or 5 flowered. Fropcr calix none. Corolla
