3. Sideroxylon Derryanum, King & Gamble, n. sp. A tree ; 
branchlets grey, uppermost appressed-pubescent ; innovations with 
nearly black hairs. Leaves chartaceous ; elliptic, very abruptly short- 
acuminate at apex, broadly cuneate at base ; margins more or less 
recurved ; glabrous above, densely silvery-pubescent beneath ; 3 to 
5'5 in. long, 1*5 to 3 in. broad; midrib prominent, impressed above ; 
main-nerves 12 to 18 pairs, parallel, starting at an angle of about 75° with 
the midrib, meeting near the margin in a faint intramarginal looped 
nerve; secondary nerves similar, rather prominent, reticulations few, 
obscure ; petiole - 3 to - 5 in. long, channelled above, pubescent with 
nearly black hairs. Flowers fascicled, about 5 together in the axils of 
the leaves or of the scars of fallen leaves ; pedicels -25 in long, tawny- 
pubescent ; buds oblong, conical. Calyx-lobes 5, rounded, obtuse, the 
2 outer thick very pubescent, the 3 inner somewhat scarious, pubescent 
only on the middle of the back. Corolla campanulate, - 2 in. long ; tube 
•15 in. long, glabrous within, with a few sparse hairs without; lobes 5, 
ovate, imbricate, margins recurved. Stamens 5, short, inserted at the 
top of the tube ; filaments conical ; anthers ovate-cordate, dehiscing by 
side-slits ; staminodes subulate, glabrous. Ovary villous, obscurely 
5-lobed, 5-celled ; style very short ; stigma obscurely 5-lobed. Berry 
oblong, dark blue, glabrous, the top flat and crowned with the 
remains of the style, •6-7 in. long, 1-seeded. Seed oblong, -6 in. 
long by '3 in. in diam. truncate obliquely at the base ; testa thick, 
light-brown, striate ; hilum rather small, sub-basal ; albumen thin ; 
cotyledons thick ; radicle small.

The colour of the silvery under-surface of the leaves is difficult to describe— it is 
sometimes dark and smoky-looking. 
4. Sideroxylon ferrugineum, Hook. & Arn. Bot. Beech. Voy. 
266, t. 55 (1841). A small tree ; branches rough, ultimate branchlets fer- 
ruginous-pubescent like the leaf-buds and young leaves, branchlets with 
a raised line downwards from each leaf or scar of a fallen leaf. Leaves 
coriaceous ; obovate or oblong-lanceolate, rounded or bluntly acute at 
apex, attenuate at base ; shining above, densely appressed ferruginous- 
silky beneath when young, ultimately nearly glabrous ; 2'5 to 6 in. long, 
1 to 3 in. broad; midrib prominent; main-nerves 10 to 12 pairs, fairly 
prominent, especially above, starting at about an angle of 60° with the 
midrib, at first nearly parallel then arching upwards to meet near the 
margin ; secondary nerves similar, reticulations oblique ; petiole ’5 to 
'7 in. long, the edges bordered by the decurrent margins of the blade, 
enlarged at base. Floivers fasciculate, shortly pedicelled, in the axils of
