and younger peduncles with yellow tomentum. Leaves large, orbicular- 
cordate, sharply acuminate, entire, dull green above and _ glabrous 
except on the pubescent nerves, silvery silky below even in the adult, 
4? in. long and nearly as broad ; petiole 4 in. long in a not fully grown 
specimen. Peduncles axillary, rigid, robust, terete, about 14 lin. thick 
and 8 in. long, terminating in corymbose many-flowered dichasia pass- 
ing into contracted monochasia ; corymb 4 in. in diam. Bracts in the 
monochasia distichous, linear-lanceolate, like the sepals silvery silky on 
the outside, the lowest 7 lin. long, scarcely exceeding 1 lin. broad. Sepals 
lanceolate tapering upwards, the three outer larger, 74 lin. long to 24 
lin. broad. Corolla funnel-shaped, 2 in. long, about 14 in. broad, bear- 
ing on the outside scattered spreading stiffish grey hairs; midpetaline 
areas bounded by strong nerves, and with a conspicuous median nerve.

234. An erect (¢) shrub with robust terete rough ochre-coloured 
branches, which, except the young shoots, are glabrous, Leaves large, 
orbicular-cordate, obtuse, palmately 7-nerved at the base, green above, 
with dense adpressed grey pubescence beneath, 44 in. long, 4? in. broad ; 
petiole robust, densely grey-pubescent, 13 in. long, bearing a black 
wedge-shaped nectary on each side at the apex. Peduncles solitary at 
the leaf-scars, crowded almost in an umbel below the new branches, 
robust, corymbose, reaching with the branches a length of 4} in., 
repeatedly dichotomous, jointe@ at the scars of the fallen lower flowers ; 
flowering branchlets bearing like the bracts and sepals an adpressed 
grey tomentum, fruiting branchlets almost glabrous like the branches. 
Upper flowers only remaining, solitary and subsessile at the joints of 
the peduncles; bracts and bracteoles deciduous, resembling and equal 
to the sepals, grey tomentose on the outside. Sepals equal, linear- 
lanceolate, about 4 in. long, scarcely 1 lin. broad. Corolla (young) 
with tube coloured (?) limb pale, grey pubescent on the outside, 
except on the commissural segments; midpetaline areas bounded by 
strong nerves. Capsule subtended by the reflexed persistent sepals, 
globose, glabrous, very closely and minutely striate, ochre-coloured, 74 
lin. long, 4-valved, the 4 cells each 1-seeded; valves thick testaceous-
