 quhoun, Bart., resident at Kamaon.) Wall, in Lin. trans. 13. 

 p. 608. tent. fl. nep. 1. p. 13-14. Benth. lab. p. 644. 



Lix. SYST. Didynamia, Gymnospermia. Calyx tubularly cam- 

 panulate, 10-nerved, subincurved, almost equally 5-toothed, and 

 having the throat naked inside. Corolla with an exserted in- 

 curved tube, which is naked inside, a dilated throat, and a bila- 

 biate limb ; upper lip erect, entire, flattish ; lower one rather 

 spreading, with 3 short ovate entire lobes. Stamens 4, ascend- 

 ing, didynamous, lower ones the longest ; filaments naked at the 

 base ; anthers approximate, 2 -celled : cells at length divaricate. 

 Style about equally bifid at top ; lobes subulate, stigmatiferous 

 at apex. Achenia oblong, dry, smooth, drawn out into a mem- 

 brane at top. Twining or scandent, usually tomentose, not pilose 

 shrubs. Whorls loose, axillary, or approximating into a termi- 

 nal spike. Bracteas minute. Corollas scarlet. 



1 C. COCCI'NEA (Wall. 1. c. tent. fl. nap. 1. p. 13. t. 6.) leaves 

 nearly glabrous, roughish, canescent from fine tomentum while 

 young, as well as the calyxes ; calycine teeth ovate, obtuse ; 

 upper lip of corolla ovate. Jy . ^ G. Native of Nipaul. Has- 

 tingia scandens, Roxb. ? Holmskioldia scandens, Sweet. ? Leaves 

 ovate, acuminated, 3-4 inches long. Whorls few-flowered, ap- 

 proximating into a spike, which is leafy at the base, and some- 

 times disposed in short axillary racemules. Calyxes tomentose. 

 Corolla scarlet, twice the length of the calyx. 



/ ar. |3, parriflbra (Benth. lab. p. 644.) young leaves and ca- 

 lyxes hardly tomentose. Ij . ^ S. Native of Gosainsthan. 

 Scarlet-fiowered Colquhounia. Shrub twining. 



2 C. VESTI'TA (Wall. tent. fl. nap. 1. p. 14. pi. asiat. rar. 3. p. 

 43. t. 267.) under surfaces of leaves, stems, and calyxes clothed 

 with white tomentum ; calycine teeth ovate, obtuse ; upper lip 

 of corolla ovate. Tj . ^ G." Native of Kamaon, Wall. Corollas

Clothed Colquhounia. Shrub twining. 



3 C. E'LEGANS (Wall. pi. rar. asiat. 1. p. 65. and 3. p. 43. t. 

 268.) stems, leaves, and calyxes clothed with velvety pubes- 

 cence ; calycine teeth broad-lanceolate, acutish ; upper lip of 

 corolla oblong. I? . ^ S. Native of Ava, on Mount Taong 

 Dong. This differs from both the preceding by the calyx 

 being one half smaller, in the corolla being more exserted, with 

 a wider throat, and in the colour being orange, dotted with blood 

 red, not scarlet. 



Elegant Colquhounia. Shrub twining. 



Cult. These elegant and curious shrubs are well fitted for or- 

 namenting rafters in greenhouses or stoves. A light rich soil 

 will answer them well, or one composed of equal parts of loam, 

 sand, and peat ; and young cuttings will strike root readily in 

 the same kind of earth under a hand-glass in a little bottom 

 heat.

 didynamous ; lower ones the longest. Achenia fleshy, rather 

 baccate.

 late lobes ; stumas minute. Achenia fleshy. Perennial herbs

 and rooting at the base. Leaves generally ample, thick, villous 

 or tomentose. Flowers rather large. Whorls sometimes spicate,

 tose beneath ; whorls crowded into a terminal spike or the lower 

 ones are remote and axillary : floral leaves bractea-formed, 

 broad ovate, exceeding the calyxes ; calyx campanulate, clothed 

 with soft tomentum, with ovate-lanceolate teeth ; corolla about 3 

 times as Icng as the calyx. Tf. . S. Native of the Burman Em-
