674 cxii. LABIATE. (J. D. Hooker.) [Colquhounia. 



38. COIiQUHOUNXA, Wall. 



Tall, robust, rambling shrubs ; branches terete. Whorls axillary and in 

 lax-fld. spikes or racemes of orange or scarlet flowers. Calyx obscurely 10- 

 nerved, subequally 5-toothed, throat naked. Corolla-tube incurved, not 

 annulate, throat inflated ; upper lip short, entire or notched, lower sub- 

 equally 3-lobed. Stamens 4, ascending ; anthers conniving in pairs ; cells 

 divaricate, confluent. Style subequally 2-fid. Nutlets winged above. 

 Species 3 or 4, Indian. 



I am quite unable to distinguish the first three species, or to reconcile their 

 specimens, descriptions and published drawings with one another. 



1. C. coccinea, Wall, in Trans. Linn. Soc. xiii. 608 ; Tent. FL Nap. 

 i. 13, t. 6, and Cat. 2085 ; branches tomentose, leaves elliptic ovate or cor- 

 date glabrate or subtomentose, calyx - in. hoary. Benth. in DC. Prodr.

TEMPERATE HIMALAYA; from Kumaon, Wallich, to Sikkim, alt. 7-9000 ft., 

 J. D. H. 



A shrub, 8-10 ft. Leaves 2-5 in., very variable in form and clothing. Flowers 

 in an original drawing named by Wallich, and in the Tentamen figure, chiefly axillary, 

 with a short subhemispheric calyx ^ in. long (Bent ham's var. ft parviflord), and dull 

 red corolla with the broad cylindric tube not twice the length of the calyx ; in 

 Wallich's and other specimens the flowers are very different, both axillary and in 

 terminal spikes, the calyx and corolla are both twice as long, and the latter has a 

 narrow tube. The plant figured in the Botanical Magazine, which was raised from 

 seed sent by Wallich, has flowers all axillary, small calyces, a corolla | in. long, 

 funnel-shaped above the calyx, with much narrower orange-red lobes, the latter 

 golden yellow at the base and in the throat. Nutlets in. long, wing obliquely 

 truncate. 



2. C. vestita, Wall. Tent. FL Nap. i. 14 ; Plant. As. Ear. iii. 43, 

 t. 267, and Cat. 2086; densely clothed with thick white wool, leaves 

 elliptic ovate or cordate, calyx ^-j in. woolly. Benth. in DC. Prodr. 

 xii. 457. 



TEMPERATE HIMALAYA ; Kumaon, alt. 6-8000 ft. ; Bhotan and Mishmi, Griffith. 

 KHASIA MTS., alt. 5-7000 ft. ; Griffith, &c. 



This, I suspect, is only a woolly variety of C. coccinea, which, owing to the wetness 

 of the climate, does not occur in Sikkim. Wallich's figure, however, represents a plant 

 of very different habit from that of C. coccinea, having long subraeemose terminal spikes 

 of rose-pink flowers 1 in. long. Of the specimens both from Kumaon and the Khasia, 

 many agree with the plate; others with smaller more axillary flowers and less clothed 

 leaves pass into C. coccinea. Khasia specimens have often very thick leaves finely 

 rugose on the upper surface, and densely cottony beneath. 



3. C. elegrans, Wall. PL As. Rar. i. 65, iii. 43, t. 268, and Cat. 2084 ; 

 densely softly tomentose, leaves shortly petioled, flowers in small axillary 

 heads, calyx in. subhemispheric, corolla-tube broad thrice as long as the 

 calyx. Bentk. in DC. Prodr. xii. 457. 



BURMA ; on Taong Dong, Wallich. 



Probably only another variety of C. coccinea, which I cannot distinguish from 

 Bentham's var. parviftora of that plant, except in the longer corolla. 



4. C. tenuiflora, Hook. f. ; branches scaberulous and hirsute, leaves 

 elliptic serrate pubescent, flowers subcapitate on very short lateral villous 

 branches, calyx in., teeth acuminate, corolla 1 in. very slender densely 

 pubescent.
