genus Calystegia of Mr. Brown, hut the involucre is here 

 smaller than the calyx, and the general habit of the plant is 

 yeiy different from tliat of the species which have been ranked 

 there; so tliat we have thought it advisable to leave the 

 species in the generic group where we have found it. 



A villously furred annual plant. Stem herbaceous, round. 

 Leaves cordately hastate, nearly three inches long, middle 

 lobe ovately acuminate, cuspidate, lateral ones several times 

 smaller, horizontal, very shortly ovate: petiole round, little 

 shorter than the blades, nearly as thick as tlie branches. 

 Peduncles solitary, 1-3 flowered much longer but slenderer 

 than the petiole, longer than or about equal to the leaf, round, 

 stiffish, sometimes twice or thrice divided at the top, with 

 two oblongly acuminate hractes under each division : pedicles 

 short. Floral bractes 2 under each flower, shorter than the 

 calyx. Calyx foliaceous, large, uuequal, villous, persistent, 

 soft, vecurvedly spreading, two outer leajiets by far the 

 largest, equal to each other, broadly ovate, sharp pointed, 

 opposite, nerved (mistaken by Willdenow for bractes ?) 3 

 inner ones of the same shape as these, much smaller, and of 

 different sizes from each other. Corolla pubescent on the 

 outside, rotately funnclform ; limb obsoletely 5-cornered. 

 Filaments subulate, membranous and winged, flattish, sub- 

 pubescent, very shallowly adnate to the tube, every one re- 

 ceived behind at their union with the faux by two small obso- 

 lete teeth. Anthers pale, upright, sagittatcly linear, nearly 

 as long as the filaments. Pistil equal to the calyx : ger- 

 men shaggy, semibilocular, 4-seeded : style capillary, hairy, 

 coloured, undivided: stigmas 2, lobeshaped, divaricate, 

 subovately oblong, thick, fleshy, granulated.
