5. T. lutea, T. Anders. in Journ. Linn. Soc. ix. 448; leaves ovate 
acuminate or lanceolate toothed, pedicels longer than the petioles, corolla 
yellow or greenish-white. 
SIKKIM, alt. 4—7000 ft., frequent; J. D. H., &c. . 
 Pubescent or nearly glabrous. Stem slender. Leaves 6 by 4 in. or (especially 
upper ones) on the same stem 4 by $in., wide or cuneate, decurrent at the base, 
feather-nerved; petiole 1-2 in. Pedicels 14-4 in., solitary, glabrous or pubescent, 
with a tuft of hairs at the base; bracteoles 3-2 in., broadly ovate or round, berbhaceous, 
connate when young. Calyx minute, shorter than the small pedicel within the 
bracteoles, crenulate. Corolla 13 in., glabrous, usually a faint yellow, greenish below. 
Stamens 4, subsimilar, fifth rudimentary ; filaments hairy [at the base, glandular 
upwards ; anther-cells lanceolate, subpendent, separate below, sparingly hairy, white, 
cells with a round green ciliate basal appendage. Style bifid, branches short, linear, 
subequal, stigmas subcapitate. 
Sect. 3. Htexacentris. Flowers racemed, or the lower axillary. 
Calyx an entire or obscurely crenulate ring. Seeds dorsally compressed, 
base plane. 
6. T. grandiflora, Roxb. Hort. Beng. 45, and FI. Ind. iii. 34; leaves 
ovate or uppermost lanceolate often angular or lobed scabrid or pubescent 
palmately 5-7-nerved, bracts deciduous lower often petioled leaf-like, corolla 
blue. Wall. Cat. 768, type sheet; Bot. Mag. t. 2366; Bot. Reg. t. 495;

BENGAL, alt. 0-4000 ft.; from Behar and Sikkim to Assam, Mumeypoor and 
Chittagong, frequent.—DISTRIB. N. Burma (cult.? in China, Singapore, Bombay, 
c.). 
A large climber; uppermost leaves often passing into bracts. Leaves 6 by 3 n» 
acute, base cordate, toothed, often angularly lobed, pubescent, rarely glabrate ; petiole 
3 in. Racemes usually stout, pubescent, angular, somewhat dense-fld., or more 
slender, elongate, nearly glabrous ; upper bracts small, inconspicuous ; pedicels 4-3 m, 
opposite or fascicled ; bracteoles 1-14 in., falcate-elliptic, acute, often cohering on one 
margin. Calyx subentire. Corolla 2-3 in. long and broad. Filaments widened 
below ; anthers subsimilar, 1— in. long, bearded ; cells parallel with a fine linear basal 
spur. Ovary pubescent or glabrescent; stigma very large, funnel-shaped ; lobes 2, 
rounded. Capsule 1-2 in., pubescent or glabrous. Seeds flat, à in. diam., sub- 
trigonous, covered (except the large base) with soft brown scaly plates.— Ordinary 
forms are easily distinguished by the pubescent angular leaves and pubescent racemes 
but some Khasian examples are altogether glabrate with entire elliptic acute leaves ; 
and, except by the leaves being 5-7-nerved rather than 3-nerved at the base, they 
might be placed with 7. laurifolia. i 
VAR. ? azillaris; leaves cordate-ovate acute glabrate, pedicels axillary 2-3 in. 
1-fid., capsule and seeds as of 7. grandiflora.—Khasia; Theria Ghaut, Clarke.— 
Stems very slender for T. grandiflora; corolla noted yellow (but ?). Marked by 
Kurz as a new species; but the examples do not show the ends of the branches. 
_ 7. T. laurifolia; Lindl. in Gard. Chron. 1856, 260; glabrous or 
innovations puberulous, leaves elliptic or oblong acuminate sinuate OT 
denticulate palmately 3-nerved, bracts deciduous, corolla blue. Bot. Mag.
