3. SiDEBOXYLON Deebyanum, 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. Floiuers 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, •&-! 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. SiDEEOXYLON FEEEUGiNEijM, Hook. & Am. 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 dowmwards 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
