Myrianthus.} CXXIIIc. MORACEH (Rendle). 235 
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, much branched, 
branches spreading at a right angle, 2-3} in. long, ultimate branchlets 
24-5 lin. long ; bracts at base of the branches narrow-lanceolate, 
blunt, caducous ; clusters of flowers subglobose, 2-24 lin. in diam., 
aggregated at the end of branches of the third or fourth order, but 
never coalescing as in M. arboreus. Flowers 3~4-merous ; sepals 
obovate, ciliolate, barely 3 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. 
im height with an erect cylindrical trunk; branchlets cylindrical, 
When young bearing short appressed dull brown hairs, ultimately 
glabrous, 3-13 in. long, 2-3 lin. thick, becoming hollow, bearing the 
tng-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 m 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 hairy later, varying much in length 
but shorter than the blade, 1-6 in. long. Stipules broadly ovate, 
acute, silky hairy, about } in. long. Male inflorescences in pairs in 
the leaf-axils, equal to or shorter than the leaf-stalk; peduncle 
hairy like the young stem, 3~23 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} lin. thick and closely beset with 
flowers; bracts at the base of the branches broadly triangular- 
ovate, densely hairy, soon falling, barely } lin. long ; flowers white, 
Tagrant ; bracteoles minute, obovate or cuneate ; perianth with 4 
very obtuse concave segments, ciliolate above ; stamens 4, scarcely 
€xceeding the perianth. Female inflorescences in pairs; peduncle 
barely 4 in. long, bearing a head of 7-15 flowers ; perianth ovoid, 
Covered with short grey hairs, about 1} lin. long and 1 lin. in diam., 
with a very small mouth through which protrudes the long spathu- 
late stigma, Peduncle lengthening to 3-1 in. long in fruit ; fruits
