Tetralopha (?) polillensis sp. nov. 
Suffrutex, ramis pendulis : inflorescentiis axillaribus, bracteatis ; calyce 
urceolato, truncato vel subtruncato, ciliolato ; corolla aestivatione valvata, 
sub anthesi plus minus ve alte divisa, lobis 4, lanceolatis, recurvis, intus 
dense lanatis ; staminibus 4 ; ovario biloculari, 2-ovulato : f oliis petiolatis, 
lanceolatis vel elliptico-lanceolatis, nigricantibus, basi aeutis, apice acu- 
minatis. 
Inflorescences axillary, rarely also terminal, / excluding the flowers 1 
cm long or more often -distinctly shorter, the flowers in one -to three 
superimposed whorls with or without a basal peduncle, the internodes, 
when any, 2 to 3 mm long; the nodes involucrate by ovate, acuminate, 
ciliate, united bracts, sometimes also with bracts similar to the leaves but 
much smaller; pedicels stout, 1 mm long, or, almost wanting: calyx ur- 
ceolate, 2.5 to 3 mm long, 2.5 mm in diameter at- the rim, the rim ex- 
tending beyond the ovary,, truncate .or very obscurely 2- or 4-lobed, eilio- 
late; corolla white, in all, 13 to 14 mm long, valvate in bud, at anthesis 
splitting about half-way to the base, the 4 lobes lanceolate, obtuse, recurved, 
their inner surfaces densely white-lanate to below the insertion of the 
stamens; filaments inserted upon the corolla about 5 mm from its base, 
about 2 mm long, the linear-lanceolate anthers 2.5 mm long, their tips 
slightly exserted; disk pulvlnate, with 2 sessile stigmas 0.3 to 0.5 mm 
long; ovary at least sometimes 2-celled with 2 collateral ovules in each 
cell, sometimes showing traces of 4 cells. 
A shrub 3 m higfl, its branches pendent (from herbarium material would 
be considered scandent), the branches 4-angled or nearly terete, covered 
with gray or yellowish-gray bark, vegetative parts entirely glabrous : leaves 
opposite, the petioles 8 to 15 mm long, the lamina subcoriaceous, blackish 
when dry, lanceolate or in smaller leaves elliptic-lanceolate, 6.5 to 13.5 
cm long, 1 to 5 cm wide, narrowed to both ends, the base acute, the apex 
forming an obtuse or subacute acumen 5 to 10 mm long; lateral veins 
7 to 9, the secondary reticulations prominent, especially on the under 
surface ; stipules ovate, obtuse, 1 mm long, connected by a stipular line. 
Polillo, beside a clearing about 1.5 km south of the town, Bur. Sci. 9064 
Robinson. The generic difficulties are connected with the nature of the ovary, 
mechanically as to its actual structure, but also as to whether it is typical 
of the species or rather a reduced state belonging to the staminate flower of a 
diclinous form. Externally, it is perfectly represented in the figure of Tetralopha 
motleyi 5 Hook, f., internally, it seems to vary, usually having the 2-eelled, 
2-ovuled condition of that species, but sometimes appearing to be 4-celled. The 
ovules were quite immature. In other words, the species might with almost 
equal propriety be placed in Gynochthodes. A Negros plant is closely allied and 
is here also described. The remaining Philippine species is T. philippinensis 
Elmer, from Sibuyan.
