very acute, 7 lin. long and about as broad at the base. Male inflor- 

 escences in pairs in the leaf-axils, spreading, equal to or longer than 

 the petiole, covered with stiff hairs, 4 in. long, nuich branched, 

 branches spreading at a right angle, 2-3^ in. long, ultimate branchlets 

 2^-5 lin. long ; bracts at base of the branches narrow-lanceolate, 

 blunt, caducous ; clusters of flowers subglobose, 2-2^ lin. in diani., 

 aggregated at the end of branches of the third or fourth order, but 

 never coalescing as in M. arhoreus. Flowers 3-4-inerous ; sepals 

 obovate, ciliolate, barely J lin. long ; stamens rather broadly linear, 

 anthers just exserted. Female flowers and fruit unknown. — Engl.

6. M. serratus, Benth. et Hook.f. Gen. PL iii. 379. A tree 30-60 ft. 

 in height with an erect cylindrical trunk ; branchlets cylindrical, 

 when young bearing short appressed dull brown hairs, ultimately 

 glabrous, f-lf- in. long, 2-3 lin. thick, becoming hollow, bearing the 

 ring-shaped scar of the stipule. Leaves leathery, elliptical to obo- 

 vate-elliptical or oblong-elliptical, sometimes 3-lobed, the lateral 

 lobes being much smaller than the main lobe, apex more or less 

 sharply acute, base acute to blunt or rounded, sometimes unequal, 

 margin sharply and unequally serrate, teeth pointing upwards, 

 becoming fewer or absent at the base, 6-20 in. long, 4-10 in. wide, 

 or in the lobed leaves to 14 in. wide, when young sparsely hairy 

 above, ultimately glabrous and shining, tomentose on the lower face, 

 midrib and ascending lateral veins prominent beneath, lateral veins 

 10-12 on each side, the lowest pair often strong and in the lobed 

 leaves forming the mid-vein of the lobe ; petiole hairy like the stem 

 when young, becoming sparsely hair^^ later, varying much in length 

 but shorter than the blade, 1-6 in. long. Stipules broadly ovate, 

 acute, silky hairy, about -J in. long. Male inflorescences in pairs in 

 the leaf-axils, equal to or shorter than the leaf-stalk ; peduncle 

 hairy like the young stem, J-2f in. long, repeatedly forking or passing 

 into three secondary branches which in turn are forked, the branch- 

 lets of the 3rd to 5th degree about 1 J lin. thick and closely beset with 

 flowers ; bracts at the base of the branches broadly triangular- 

 ovate, densely hairy, soon falling, barely J lin. long ; flowers white, 

 fragrant ; bracteoles minute, obovate or cuneate ; perianth with 4 

 very obtuse concave segments, ciliolate above ; stamens 4, scarcely 

 exceeding the perianth. Female inflorescences in pairs ; peduncle 

 barely J in. long, bearing a head of 7-15 flowers ; perianth ovoid, 

 covered with short grey hairs, about IJ lin. long and 1 lin. in diam., 

 with a very small mouth through which protrudes the long spathu- 

 late stigma. Peduncle lengthening to J-1 in. long in fruit ; fruits
