476 CX¥XV. EUPHORBIACEE. (J. D. Hooker)  [Sebastiania. 
oblong, mottled.—I can find no character whereby to separate the specimens with 
terete, and those with grooved ribbed stems, 
GENERA OF DOUBTFUL AFFINITY. 
75. LOPHOPYXIS, Hook. f. 
A glabrous climbing shrub. Leaves alternate, shortly petioled, quite 
entire, 3-nerved at the base. Flowers small, monoecious, cymose, cymes 
in lax elongate branched axillary and terminal panicles, females towards the 
base of the branches. Mate ru. Calyx 5-partite, persistent; lobes ovate, 
spreading, valvate, tomentose. Petals minute, oblong, tomentose, inserted 
under the obcordate lobes of a thick disk. Stamens 5, alternate with the 
disk-lobes, filaments short pubescent; anthers short; cells oblong, dehis- 
cence extrorse, connective minutely produced. Pistillode small, villous. 
Fem. FL. Perianth of the male. Disk annular, crenate. Ovary tomentose, 
5-celled ; stigmas 5, sessile, subulate, recurved ; ovules 2, linear, collaterally 
pendulous in each cell, obturator 0. Young fruit cylindric-oblong, finely 
tomentose, deeply 5-grooved and ribbed. 
L. Maingayi, Hook. f. in Ic. Plant. t. 1714. 
Mauacca, Maingay (Kew Distrib. 1429). 
Branchlets brown, grooved, puberulous. Leaves 4-6 in., coriaceous, ovate from 
a broad subcordate base, subcaudately acuminate, shining and minutely reticulate 
above, purplish brown beneath ; nerves 4—5 pair above the short basal, cross-nervules 
reticulate; petiole 4 in.; stipules not seen. Panicles a foot long, drooping, rachis 
puberulous, branchlets hoary-tomentose ; flowers 4^5 in. diam., very shortly pedicelled ; 
buds globose, bracts very minute. Sepals tomentose on both surfaces. Young fruit 
3 in. long, crowned with the subulate styles, grooves extending almost to the 8x!s, 
ridges obtuse.—I am very uncertain as to the affinities of this curious plant, which 
resembles no Euphorbiaceous one known to me. 
76. BOTRYOPHORA, Hook.f. 
A glabrous tree. Leaves alternate, long-petioled, coriaceous, elliptic- or 
oblong-lanceolate, caudate, quite entire, penninerved. MALE FL. sessile on 
the simple horizontal branches of an erect terminal ? puberulous pyramida 
brachiate panicle; buds pisiform, globose, glabrous. Perianth membranous, 
bursting irregularly. Stamens very numerous in a globose mass ; anthers 
peltately attached to a central receptacle, imbricating ; connective broad, 
disciform with 4 minute oblong free cells in two pairs pendulous from its 
outer margin. 
B. Kingii, Hook.f. 
PERAK, in open sandy soil near the coast, King’s Collector. 
A tree, 40-50 ft. ; branchlets woody, knotted ; bark red brown, smooth. Leaves 
8-10 by 3—4 in., pale yellowish brown when dry, base acute; nerves 10-12 pairs, 
very strong, raised on both surfaces, cross-nervules finely and strongly reticulate ; 
petiole 23—4 in., strict, geniculate at the base of the leaf, terete ; stipuies not seen. 
Panicles 6-10 in. long, 4 in. diam. at the base, terminal and axillary, shortly 
peduncled, rachis and branches rigid; bracts minute. Male fl. à in. diam., al 
yellow half red, waxy. Stamens yellow.—This may be allied to Mallotus or Maca, 
ranga, but 1 know nothing at all like it, and it is too remarkable a plant to be passe 
over. The anthers, which are in a young state, recall on a minnte scale those of # 
Cycas ; the connective is very large in proportion to the cells, which are distant from 
one another.
