Dr Graham's Description of New or Rare Plants. 169 



with very short pubescence, bright green above, somewhat glaucous be- 

 low, middle rib very strong, ana with the veins prominent below. Pe» 

 duncles axillary, opposite, 4.sided, closely applied to the upper surface 

 of the leaves, and (including the pedicels) about a fifth of their length, 

 pubescent, bracteate, trifid, the lateral branches again dividing in 

 the same way ; pedicels like the peduncle, but Mss distinctly angled. 

 BracteoB lanceolate, entire, acuminate. Calyx green, oblique, 5-ribbed, 

 6-toothed, pubescent on the outside, persisting. Corolla (8 lines long, 

 A\ across) yellow, bilabiate ; tube elongated, compressed laterally in its 

 lower, vertically in its upper half, nearly thrice the length of the calyx ; 

 upper lip bifid, revolute, lower lip spreading forwards, plicate, trifid, re- 

 volute at the apices, all the lobes rounded ; two very prominent ridges, 

 very hairy, and somewhat orange-coloured, extend backwards into the 

 corolla from the central lobe of the lower lip. Stamens didynamous, in- 

 cluded ; filaments glabrous, yellow, adhering to the corolla for about 

 half their length, connivent ; anthers bilobular, lobes divergent ; pollen 

 white. Pis^iV as long as the stamens; stigma bifid, white, lobes broad, 

 revolute, upper surface pubescent ; style straight, white, filiform, gla- 

 brous, marcescent ; germen ovate, green, glabrous, 4-valved, bilocular ; 

 ovules very numerous, attached to a large central receptacle, a trans- 

 verse section of which presents a kidney, shaped surface in each locula- 

 ment. 

 This plant was raised in the garden of P. Neill, Esq. at Canonmills, from 

 Mexican seeds communicated by Mr D. Don as a species of Conobea^ 

 and flowered in the greenhouse in September. 



Loasa incana. 



L. incana ; suffruticosa, suburens ; caule suberecto, ramoso, foliisque 

 sparsis, petiolatis ovato-lanceolatis, inciso-serratis, incano, scabro ; pe. 

 dunculis simplicibus oppositifoliis. 

 Description. — Suffruticose. Whole plants particularly the stem, densely 

 covered with harsh barbed white hairs, and a few stinging hairs inter- 

 spersed. Stem round, much branched, branches scattered, spreading. 

 Cuticle papery, and peeling off in the dried specimen. Leaves scattered, 

 petioled, spreading, ovate, acute, hispid on both sides, veined, incise-ser- 

 rated, veins and midrib prominent below, channelled above. Flowers 

 opposite the leaves, solitary, peduncled. Peduncles spreading, about half 

 the length of the leaves, round. Calyx green, spread wide, segments 

 ovato-acuminate, 3-ribbed, undulate, reflected in their sides, persisting. 

 Corolla white, 10-parted, uniseriate, alternate, segments alike, the larger 

 segments spreading, cucullate, nerved and veined, longer than the ca- 

 lyx ; the smaller segments nearly glabrous, slightly ciliated, concave 

 within, nectariferous, each having near its rounded apex three erect 

 dorsal filaments as long as itself. Stamens numerous, nearly as long as 

 the longer segments of the corolla, and lodged within them till the pol- 

 len is ripe, when they become erect, free, unconnected with each other, 

 mostly perfect, with simple, colourless, slightly flattened, glabrous fila- 

 ments, and greenish .yellow, oblong, bilocular anthers, erect, bursting 

 along the sides ; 10 barren, 2 within each of the shorter petals, spread- 

 ing and flattened at the base, there ciliated, each having a reflected lip 

 at the apex of the petal within which it is placed, and above this ex- 

 tended into an erect filament, nearly as long as the fertile stamens. Style 

 erect, simple, shorter than the stamens, tapering, nearly smooth towards 

 the top. Stigma capitate, small, lobed, smooth. Germen top-shaped, 

 inferior, green, unilocular, with 3-4 parietal receptacles, alternate with 

 the teeth, covered along their edge with numerous ovules. Capsule open- 

 ing by 3-4 teeth above the level of the calyx. Seeds obovato-oblong, 

 mniute, brown, pitted, embryo straight. 

 This plant was raised from seeds communicated in spring last from Yazo, 

 valley of Canta, in Peru. Mr Cruckshanks only observed one plant, 

 low and branching, with the branches much entangled. From this he 

 also most kindly presented me with a well dried specimen, from which.
