476 cxyxv. EUPHORBLACEJ;. (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 01 DOUBTFUL AFFINITY. 



75. XiOPHOPYXXS, HooJc.f. 



A glabrous climbing shrub. Leaves alternate, shortly petioled, quite 

 entire, 3-nerved at the base. Floivers small, monoecious, cymose, cymes 

 in lax elongate branched axillary and terminal panicles, females towards the 

 base of the branches. MALE FL. 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.

MALACCA, 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 in. ; stipules not seen. Panicles a foot long, drooping, rachis 

 puberulous, branchlets hoary-tomentose ; flowers -^ in. diam., very shortly pedicelled ; 

 buds globose, bracts very minute. Sepals tomentose on both surfaces. Young fruit 

 ^ in. long, crowned with the subulate styles, grooves extending almost to the axis, 

 ridges obtuse. I am very uncertain as to the affinities of this curious plant, which 

 resembles no Euphorbiaceous one known to me. 



76. BOTRYOFHORA, HooJc.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 pyramidal 

 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. Xingrii, HooJc.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 2^-4 in., strict, geniculate at the base of the leaf, terete; stipules 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 fi. in. diam., half 

 yellow half red, waxy. Stamens yellow. This may be allied to Mallotus or Maca- 

 ranga, but I know nothing at all like it, and it is too remarkable a plant to be passed 

 over. The anthers, which are in a young state, recall on a minute scale those of a 

 Cycas ', the connective is very large in proportion to the cells, which are distant from 

 one another.
