14 DIANDRIA. MOXOGYNIA. 



bilribiatc, superior S-lobed» inferior 2-Iobed 

 slioi'ter; faux (or juncture of the labiaj) contrac- 

 ted. /S'tamma 2 very short. Style short. Stigma 

 Wlamellate covering the anthers. Capsule 1- 



the corolla emarpjinate, lower obtuse with an abrupt point; spur 

 •«(raig-ht, subulate and acute, a little incurved, and about the 

 length of the corolla; the root fibrous. South Carolina. 



9. Cornuta. I'aking- root in the ground; scape rigid, 1 to 2 feet 

 high, 2 to 3-Hovvered, fioweis large, the lower lip 3 lobed, 

 ver)- wide; spur longer than the corolla, porrected, nearly verti- 

 cal, subulate, and acute. 



Abundant on tlic Table rock, at the 1^1! s of Niagara, and 

 throughout Canada and the Alleghany mountains to Virginia, 

 in calcareous soil. 



30. fetacea. Michaux. 



Scape minutf^-, rooting, and without leaves, slenderly seta- 

 ceous, distantly 2 to 3 flowered; flowers upon longish pedicells; 

 spin' rather long. 



Mr. l..e Conte says, scape many-flowered (4 to 7 on short pe- 

 duncles, El.) upper lip of the corolla ovate, lower .strongly 3- 

 lobed; spur subulate, as long as the lower lip of the corolla. 



Lower division of the calix slip,htly ennarginate El. This de- ^ 

 scriinlon does nf)t appear to accord with iNlichaux's plant, and 

 f t)ll appears to be nearer it than tmy other. It cannot possibly 

 be the U. siibuhtta of Pursh, and the synonym of Cronovius ap- 

 plies probably to the U- setacea of Mich.— Persoon adds, that 

 the flowers of the subulahx are white; a circumstance entirely 

 improbable. 



T])e whole of this genus appears in confusion, scarcely ex- 

 cepting the European part of it; and none of the smaller and am^ 

 biguous species which are now greatly multiplied, can be under- 

 stood but* by a monograph accompanied with accurate deline- 

 ations. 



Besides the above 10 species, there are 6 others growjjig 

 within the tropical regions of America. A blue flowered species 

 in Ceylon, with 2 others in India, one in China, doubtful appa- 

 rently as to the genus, and 3 species in Kurope. America has,' 

 then, 16 species out of 23; of which one, in Martinique, is said 

 to pi'oduce large white flowers, and entire ovate leaves! The U. 

 tinifoUa of Peru rather appears to belong to the family of the 

 Orchidex, having a single radical lanceolate leaf, a solitary floW' 

 er, and a large cordate calix; it possesses, in sh»rt, all the ha- 

 bits oi' a Cymbidium or Areihusa.
