PiNCKNEYA. RVBIACEM. 37 



form : stigma obtusely 2-lobed. Capsule subglobose, coriacco-chartaceous, 

 2-valved, loculicidal. Seeds numerous, horizontal, in a double series, flat, 

 with a reticulated membranaceous wing. Embryo large, straight: cotyle- 

 dons foliaceous, concave. — A large shrub or small tree; the young branches 

 &c., hirsute-tomentose. Stipules one on each side, linear-subulate, cadu- 

 cous. Flowers large, in small cymes, which are terminal or in the axils of 

 the upper leaves. Corolla purplish inside, hirsute-canescent externally.

Swamps, S. Carolina! to Middle Florida ! May-June. — Stems or trunks 

 often clustered. Leaves oval, acute or acuminate at both ends, on short pe- 

 tioles, nearly glabrous above, pubescent or somewhat tomentose beneath, 4- 

 8 inches long, and 3 or 4 broad. Limb of the calyx somewhat colored ; one 

 (or sometimes two) of the segments dilated into an oval membranaceous 

 (rose-colored) petioled leaf, two or three inches in length. Corolla an inch 

 and a half long ; the segments shorter than the tube. Capsule about half an 

 inch in diameter ; the dehiscence loculicidal and at length [)artly septicidal 

 also. — This genus is doubtless sufficiently distinct from Musssenda, to which 

 Jussieu joined it, and with which it accords in habit. The bark has the 

 taste and medicinal properties of Cinchona, and probably contains the same 

 or a new alkaline principle. 



Tribe VL HEDY0T[DE7E. Cham, [y Schlecht. 



Fruit capsular, 2-celled, usually loculicidal (rarely somewhat mem- 

 branaceous and indehiscent) ; the cells several-many-seeded. Seeds 

 wingless. Albumen fleshy. ^Estivation of the corolla mostly imbri- 

 cated or contorted. — Herbs or shrubs. Stipules between the petioles, 

 either one or two on each side, or frequently united with the petioles 

 into a membranaceous sheath, which is often fringed with bristles, as in 

 SpermacocecB.

Hedyotis, Houstonia, & Oldenlandia, Linn. — Anotis &c., DC. 



Calyx-tube ovate or globose; the limb 4- (rarely 5-?) toothed or cleft, 

 persistent. Corolla infundibuliform, hypocrateriform , or rotate, 4- (rarely 

 5-?) lobed ; the lobes imbricate in aestivation. Stamens as many as the 

 lobes of the corolla, inserted either in the throat or towards the base of the 

 tube. Stigma usually 2-clcft or 2-lobed. Capsule globose, ovoid, or obcor- 

 date, mostly coriaceous, the summit often free from and exserted beyond the 

 calyx, 2-celled, opening across the summit by loculicidal dehiscence, and at 

 length often slightly septicidal. Seeds few or numerous, on placentae (either 

 ascending or horizontal) which project into each cell, with a reticulate-punc- 

 tate or scrobiculate testa. — Herbs, or suffruticose plants. Sti])ules connate
