Negros, Province of Negros Oriental, Cuernos Mountains, Elmer 10331 (type 
collection) : Province of Negros Occidental, Himugaan River, Whitford 158Jf. 
Leyte, Palo, Elmer 1270. Neither of the other collections is a perfect match for 
the type. 
This, on vegetative characters, is very close to Elatostema mesargyreum 
Hallier f., as represented by a sheet of the type collection, the only notable dis- 
tinction being the presence of very greatly reduced subopposed leaves on the 
Bornean plant. It is pistillate, and as only the staminate inflorescence and 
flowers were described by Hallier, it is worth stating that the pistillate are quite 
as here described for Elatostematoides. Both of the Philippine collections, other 
than the type, are staminate : the inflorescence is a condensed cyme, very different 
from that described and figured by Hallier for E. mesargyreum. 
The alliances are very accurately stated in the original description, as it is more 
closely allied to Elatostema rostratum Miq. than to the other Philippine species. 
Comparison with Javan material shows it to differ in the much coarser reticula- 
tion of the less numerously toothed leaves.

Samar, Cuming 1671f. Negros, Province of Negros Occidental, Himugaan River, 
Whitford 1655. Cuming’s specimen having been staminate, it should be added 
that the pistillate inflorescences are sessile, exinvolucrate, the perianth 5-parted, 
not mueronate, but ciliate, exceeding the ovary, and that staminoles are present. 
The Negros collections are an excellent match for the cotype. 
5. Elatostematoides gracilipes sp. nov. 
Inflorescentiis staminiferis in pedunculis longiusculis graeilibusque 
suffultis, aliquando parce ramosis, glomerulis parvis, paucifloris, exinvol- 
ucratis; inflorescentiis pistilliferis sessilibns, parvis, exinvolncratis, per- 
ianthio alte 5-parti±o, achenio subaequali: foliis alternis, firmiter mem- 
branaceis, lanceolatis ad oblanceolatis, basi obtnsis vel uno latere aeutis, 
margine supra medium dentatis, apice acuminatis. 
Staminate inflorescences on slender pubescent peduncles usually 15 
to 25 mm long, usually bifurcate and sometimes further divided, the 
glomerules up to 3 mm in diameter, bracted. at ' the base but not truly 
involucrate, pedicels short, bearing a whorl of bracts below the flowers: 
perianth-segments 5, oblong-ovate, 0.8 mm long, ciliate: pistillate in- 
florescences sessile, greatly condensed but not forming a receptacle, 
exinvolucrate; perianth deeply 5-parted, the segments linear-lanceolate, 
0.8 mm long, barely acuminate but with .a tuft of cilia at the apex; 
staminodes minute ; ovary compressed, ovoid, nearly as long as the 
perianth; stigma short, penicillate. 
Sufcratescent, about 50 cm high, the stems distinctly woody, widely 
branching, especially toward the apices densely pubescent : leaves alternate, 
subsessile, the lamina membranaceous but firm, lanceolate to oblanceolate, 
sometimes broadly, 2 to 4 cm long, 8 to 13 mm wide, rarely opposed by
