174 Dr Graham's Description of New or Ra^-e Plants. 



with two teeth on each side nearly as long as those of the lower lip, at 

 first spreading, but as the corolla fades, becoming erect, and finally, with 

 the sides of the calyx, advancing so as to contract its throat; all the teeth 

 terminated by hard bristles, whole calyx slightly pubescent on the outside. 

 Corolla bilabiate ; lower lip short, 3-lobed, withering almost immediately 

 after expansion ; upper lip elongated, equal in length to the tube, nearly 

 straight, but slightly arched at its extremity, and 2-toothed, the whole 

 of the corolla except the lower lip and base of the tube, which are smooth, 

 thickly covered with red shaggy hairs, diminishing from the apex of the 

 upper lip downwards. Stamens 4, didynamous, rather longer than the 

 upper lip, and hanging loosely ; filaments arising from the throat of the 

 corolla, subulate, nearly colourless, slightly pubescent; anthers crescent- 

 shaped, pale yellow, attached by their backs to the filaments, smooth. 

 ' Germen elongated, and truncated ; style filiform, nearly as long as the 

 stamens ; stigma cleft, one of the segments very small. 

 The figure in the Botanical Register is very good, and the description gene- 

 rally correct, though both were made from a dried specimen. There is 

 a wide range over which it appears that this species is found native. It 

 is certainly the same as the East Indian plant, as is remarked in the Bo- 

 tanical Register. From the statement in the same work, there is rea- 

 son to believe that it grows in the neighbourhood of the Congo. In the 

 Herbarium of this University, there is an indigenous specimen from 

 Dominica, communicated, along with a valuable collection, by my friend 

 Staff-Surgeon Lyons ; and our plants in the Botanic Garden were raised 

 from seeds, collected by Dr Gillies, in South America, and received 

 through Patrick Neill, Esq. in May last. They have been kept in the 

 stove. 



Loasa patula. 



Xf patula ; capsula contorta, quinque loculari ; calyce marcescente. 



Description — Root branching, fibrous. Sterna herbaceous, numerous, 

 spreading wide, ascending, branched, 4-sided, pale, succulent, semipellu- 

 cid, streaked with deep green. Leaves opposite, decussating, petioled, 

 spreading, 3-lobed, the middle lobe by much the longest, lobes doubly in- 

 cised, each with a strong branching middle rib ; petioles channelled, and 

 stem clasping. Peduncles axillary, erect, tapering, round, longer than the 

 leaves. Bractece^ 2 at the top of the peduncle, small, subulate. Flowers 

 nodding. Cal^ of 5 subulate segments, marcescent. Corolla S-petaled ; 

 petals white, spreading at right angles to the axis of the flower, cucul- 

 late, compressed, clawed, with one, sometimes two teeth, on each edge, at 

 the lower part of the limb, and one at the extremity. Stamens numerous, 

 inserted into the receptacle, inclosed by the petals, till the pollen is 

 ripe, when they become erect, and advance to the centre of the flower ; 

 filaments reaching half-way up the hollow of the petals, filiform, colour- 

 less, united into five bundles at the base ; anthers short, bilocular, burst- 

 ing at the side, greenish-yellow; pollen white. Germen inferior, ob- 

 ovate, twisted, green, quinquilocular, seeds numerous, and attached to 

 the dissepiments ; style straight, cylindrical, pointed at its extremity, at 

 first shorter than the nectaries, afterwards nearly twice as long; stigma 

 very minute ; nectaries ten, slender, flattened, curved, half the length of 

 the filaments, and included in pairs in five sheaths, which are erect in 

 the centre of the flower around the style, opening longitudinally on 

 their inner side, yellow, with two reddish-orange bands passing a- 

 cross them near their apex, and two terminal oblong spots : the first 

 band consists of short broad streaks, arranged side by side, and- longi- 

 tudinally in reference to the sheath ; the second of a continuous, 

 somewhat projecting edge. At the base of each sheath, and equal 

 to more than half its length, there are three spreading yellow threads, 

 and at the apex two smaller, and colourless ; the last at first erect, 

 afterwards recurved. Whole plant, even to the corolla, covered 

 with inverted stinging hairs, which arise from glands, and transmit
