9. S. triloculare. Pax d: K. Uoffm. in Engl. Pflanzenr. Euphorh- 

 Hip2X)7nan. '2h\,Jig. 48 F. A tree, 18-25 ft. high, glabrous everywhere 

 except on the margins of the stipules ; twigs slender, perulate at the 

 base, scales oblong, obtuse. Leaves short-petioled, membranous or 

 thinly papery, oblong-ovate, more or less cuspidately acuminate, base 

 cuneate or somewhat rounded, minutely auriculate-cordate, but not 

 glandular, at the point of junction with the petiole, margins entire or 

 obscurely crenulate-toothed, 2J-3J in. long, 1-1 J in. wide, dark green 

 above, paler beneath ; lateral nerves 7-8 on each side ; petiole slender, 

 ^-J in. long, slightly channelled above; stipules large, oblong- lanceo- 

 late, acute, \ in. long, with ciliate margins, otherwise glabrous, very 

 caducous. Spikes terminal on the twigs, 2J-8 in. long, appearing before 

 the leaves which sometimes fail to develop, the scaly branch below the 

 lateral leaf-bud at the base of the spike J-| in. long, with many rather 

 lax distinctly pedicel led male flowers above, and usually 2 distinctly 

 pedicelled basal female flowers ; male bracts small, suborbicular, acute 

 or obtuse, denticulate, 2-glandular at the base, each 3-12-flowered ; 

 female bracts oblong-lanceolate, acute, ^ in. long, eglandular, like the 

 stipules but smaller and not or obscurely ciliate on the margin, each 

 1-flowered ; pedicels in both sexes exceeding the bracts, males distinctly 

 articulate, females twice as long as the males in flower. Male : Calyx 

 cupular, 2-3-lobulate ; lobes denticulate. Stamens 2, shortly exserted; 

 Female : Calyx deeply 8-sect ; lobes wide-triangular, acute, denticulate, 

 with a large gland at each sinus. Ovary glabrous, not horned, 3-celled ; 

 styles 3, shortly connate at the base. Capsule with a thin leathery 

 exocarp and a very thick woody endocarp, slightly 3-dymous, breaking 

 up rather tardily into three 2-valved cocci, J in. across; pedicel in fruit 

 J in. long. Seeds narrowly ovoid-cylindric, smooth, brown.

A very distinct species, remarkable among its allies as having no horns on the 

 cocci. 



10. S. mannianum, Benth. in Benth. et Hook.f. Gen. PI. iii. 335. 

 A tree of very variable size, sometimes exceeding 100 ft. in height, 

 glabrous everywhere except the tinely puberulous inflorescence, and 

 occasionally the scaly portion of the young twigs ; branches drooping ; 

 twigs slender, perulate at the base, scales coriaceous, ovate or sub- 

 orbicular, obtuse, caducous. Leaves short-petioled, firmly membranous 

 to thinly coriaceous, oblong-ovate or -obovate to oblong-elliptic or elliptic- 

 lanceolate, acute to shortly cuspidate, base cuneate to rounded, minutely 

 auriculat€-cordate and with usually 1-2 glands on each side above the 

 junction with the lamina, margin more or less toothed, rarely subentire,
