new or rare plants, sent to the exhibition of the Society, 

 have attracted much notice and commendation. It is a 

 native of Peru. 



Descr. Stem (three feet and a half high) subligneous, slender, 

 branched, joints slightly swollen ; cuticle white, cracked, exfoliating at 

 the base : brandies erect, but, as well as the stem, requiring support. 

 Leaves opposite, petioled, suberect; lamina (four inches long, one 

 broad) deeply pinnatifid, dark and rugose above, paler and strongly 

 veined below, having on both sides long, stinging hairs, rising from 

 large glands, and short, somewhat roughened hairs on smaller glands, 

 the former most numerous on the upper, the latter only crowded on 

 the lower side; segments ovate, blunt, lobed, more and more distant 

 and less and less connected downwards, till they nearly separate into 

 distinct pinnae ; petiole about half the length of the lamina. Peduncles 

 (four inches long) round, erect, axillary, solitary, alternate. Calyx- 

 tube turbinate, adherent, short, having ten prominent, straight, longitu- 

 dinal ribs ; limb rather longer than the tube, reflexed before the flower- 

 bud has attained its full size, segments acute, slender, pinnatifid. 

 Corolla (fully two inches across, when expanded) spreading, but not 

 reflexed; petals ten, alternately large and small, the larger (one inch 

 long, and as much broad) alternate with the calyx-segments, and four 

 times as long as them, of nearly uniform orange colour on both sides, 

 scarcely clawed, obovato-rotund, boat-shaped in the centre, with broad 

 spreading sides, which are reflexed in the two lower thirds, much veined, 

 the veins chiefly in three loose fasciculi placed in the centre, and where 

 the sides are reflexed; the outside, like the stem, peduncle, and calyx, 

 having both the forms of hairs found on the leaves, the inner side sub- 

 glabrous, and having the small hairs only : the smaller petals opposite 

 the calyx-segments, and scarcely as long as them, cucullate, cartila- 

 ginous at the base, colourless, nectariferous, having two slender, orange- 

 coloured threads near the apex. Stamens very numerous, inserted 

 along with the petals, two, which are abortive, arising within each of 

 the shorter petals, twice as long as them, subulate, free, and having 

 concave, crescent-shaped appendages at the base, reflexed into the 

 shorter petals ; — the other stamens are fertile, and collected in fasciculi 

 in front of, and half the length of the larger petals, free to the base ; 

 filaments colourless, slightly tapering upwards ; anthers yellow, pollen 

 granules minute, colourless, connected by threads. Pistil shorter than 

 the stamens ; stigma extended in three narrow lines along the apex of 

 the style ; style only fully developed after impregnation, its apex pris- 

 matic, with three very prominent angles or wings; germen top- 

 shaped, with ten prominent, straight, vertical nerves, unilocular, and 

 covered on the top with a large, green, five-lobed, bifid disk; placenta 

 three, parietal, large and bifid, covered with very numerous small 

 ovula. — Graham.
