loosely sprinkled with hairs similar to those on the stem. Petioles (1 

 inch long) rather shorter thaa the leaves, having a shallow groove along 

 their upper surface, ciliated. Stipulce subulate, ciliate, green, spreading, 

 connivent at the apices. Peduncles (3 inches long) sohtary, axillary, longer 

 than the leaves, loosely provided with hairs like those on the other parts 

 of the plant, slightly tapering, jointed near the calyx, but not swollen 

 at the joint. Flowers large, inodorous. Calyx persisting, 5-cleft, green, 

 moi-e hairy both within and without than any other part of the plant, 

 tube somewliat fleshy, and lighter coloured than the cordato-ovale, acute, 

 more membranous segments, the edges of which are compressed and pro- 

 minent in the bud. Corolla three times as long as the calyx, rose co- 

 loured, veined, flat (then 2 inches across) and becoming paler when 

 fuUv expanded : petals 5, obovato-cuneate, obliquely emarginate, gla- 

 brous, ciliated at the base, aestivation contorted. Stamens monadelphous, 

 numerous; sheath pale rose colour, bearing at or near the top the par- 

 lial filaments, which, as well as the anthers, are darker, and orange-red ; 

 anthers kidney-shaped, dotted, bursting by a suture along the back ; 

 pollen globular, smooth, yellow. Styles numerous, cohering at their 

 base, equal in length to the stamens, purple, under the microscope ap- 

 pearing rough. Stigmas flat, deep purple, villous. Germens numerous, 

 each containing a single ovule, green, dotted, glabrous, collected irregu- 

 larly into a head, inclosed within the calyx. 

 This is a verv pretty plant, and if it will bear cultivation as an annual in 

 the open border, wiU soon become common. The seeds were received 

 from Mr Cruckshanks in spring last, having been collected near Lima. 

 It bears a profusion of blossoms in a hot-bed at the Botanic Garden. 

 It must come very near to Palaua mosckata of Cav. Dissert, i. p. 41. t. 1 1. 

 fig. 5., Palavia moschata of later writers, but that is described as tomen- 

 tous, the stem erect, the leaves cordate, the petals subrotund and yel- 

 low, passing into purple, the stipules coloured, and the figure represents 

 a tumefaction at the joint of the peduncle, which is quite awanting in 

 our plant ; nor can 1 perceive that any part of the plant is at all per- 

 fumed.

Desckiption An evergreen procumbent shrub (about 6 inches long) ; 



branches at length divaricated, round, grey, when young red, obscurely 

 pubescent, warted. Leaves (8 lines long, 4 broad) pelioled, divaricated, 

 elliptical, veinless, reflexed at the edges, dark green above, pale green 

 and at last yellowish below, thickly sprinkled on both sides with hollow 

 dots, which are covered with an umbilicated persisting yellowish scale, ob- 

 scurely channelled along the middle rib, which is somewhat prominent 

 behind. Flowers terminal, umbellate (about 5 or 6 in the umbel, of which 

 3 expand at a time), surrounded with large, concave, imbricated, brown, 

 doited scales or bracteae. Peduncles the length of the bracteae, round, dot- 

 ted. Calyx small, 0-toothed, bkmt, ciliated, thickly covered with yellow 

 scales. Corolla (three-fourths of an inch across) crimson, rotato-funnel- 

 shaped, 5-cleft, segments blunt, unequal, undulate, throat hairy, nectari- 

 ferous, nectariferous pore very indistinct. Stamens 5-8, equal to the 

 length of the corolla, scarcely "declined ; filaments adhering to the base 

 of the gernien, of the same colour as the corolla, hairy near their base ;
