brunneo-velutina, trinervia, costa media prominente nervis 2 lateralibus, arcuato-

Hab. Arfak Mts., Angi lakes, edge of forest by 2? lake, 7000’. Fl. 9, 
Fr. Dee. 5955. 
Leaves +6 em. by 175 cm., green, but drying a dusty brown, densely 
covered on the upper surface with punctiform cystoliths. Petioles 1:3 cm.,, 
slender, densely puberulous, Stipules 4 mm., lanceolate, acute, tomentose 
on the outside. Glomerules 4 mm. across, in fruit, forming a white swollen 
receptacle. Flower 3mm. long; style filiform, hirsute, 2°5mm. Achene 
+1 mm. long, covered with short stiff white hairs. 
This plant is distinct in the small narrow leaves with scabrid upper 
surface and the very well-marked network of minor veins, forming minnte 
interstices, covered with dense brown tomentum on the under surface. In 
the shape of the leaves it is nearest to P. mindanensis Elm., but differs in the 
small size, more rigid texture and entire margins, the prominent venation 
with fewer lateral veins, and the brown coloration when dry.

GipBstA Rendle, gen. nov. (A. B. RENDLE.) 
Flores monoici, unisexuales: Maseuli alabastro depresso-globosi, mucronati ; 
perianthio fere ad basin 5-partito, segmentis valvatis, ovatis. Sfamina 5, antheris 
subrotundis, dorsifixis, in alabastro inflexis. Ovarii rudimentum lanuginosum. 
Feminei perianthio brevi, late cupuliforme, persistente et basin fructus cupula 
carnosula adnata tegente. Ovariwm ovoideum valde obliquum; stigma apicale, 
sessile, discoideum, papillosum, margine setulis fimbriato; ovulum a basi erectum, 
micropyle elongata, superne ampliata et fimbriata. Fructus subdrupaceus, parvus, 
valde obliquus, exocarpium tenue, carnosulum, et super cupulam demum separabile, 
endocarpium crustaceum. Semen conforme, testa membranacea ; albumen carnosum ; 
_cotyledones parve, ellipticw ; radicula superior. 
Frutices, foliis alternis, petiolatis, crenato-serratis, 3-nerviis, subtus canescentibus. 
Stipule membranacex, in unam intrapetiolarem alte bifidam connatex, decidue. 
Inflorescentie axillares, solitariz vel bine, foliis multo breviores, dichotome. 
Flores in cymulis parvulis androgynis apice ramulorum ultimorum breviter pedi- 
cellati. Bractee minute, ovate, scariose. 
Recalls the genus Debregeasia in its leaf-characters, but in characters of 
flower and fruit is nearest the Malayan and Pacific Island genus Leucosyke, 
which, however, has a penicillate stigma and the fruits crowded on a fleshy 
receptacle ; there is no trace of a fleshy receptacle in Gibbsia. The fruit is 
very characteristic; the upper portion of the thinly succulent exocarp 
separates like a cap, and the endocarp enclosing the seed is then readily 
separable from the cup formed by the union of the somewhat fleshy perianth 
with the lower part of the exocarp.
