oblanceolate, acute or sometimes on - one side obtuse, at the usually 
distinctly inequilateral base, the margins entire or more rarely toothed 
near the apex, which is contracted into a slender or only comparatively 
wide obtuse falcate acumen up to 2 cm long; smaller leaves often present 
and opposite or nearly opposite the larger, narrowly elliptic or elliptic- 
lanceolate, 2 to 4 mm long ; costa distinct, especially on the under surface, 
mature leaves at the most barely showing the lateral veins ; both surfaces 
with cystoliths; stipules short, triangular, obtuse. 
Luzon, Province of Bataan, Mount Mariveles, Merrill 3884 (type)- Polillo, 
Aluyon, Bur. Sc i. 9246 Robinson. The first grew erect on cliffs at an elevation of 
1000 m, the second was scandent, but almost at sea-level. The species seems quite 
distinct from P. laevigata in its sessile and solitary pistillate inflorescences, as 
well as by the obscure leaf-venation. 
2. Procris lagunensis sp. nov. 
Praeeedenti similis, sed differt eapitulis pistilliferis multo majoribus, 
usque ad 15 mm diametro et foliis oblongo-ellipticis, saepius latioribus. 
Staminate inflorescences similar to those of the preceding species : 
the pistillate sessile, solitary, 7 to 15 mm in diameter when dry, the 
flowers very numerous, sessile ; perianth parted almost to the base, the 
segments' 4, oblong-lanceolate, about 0.7 mm long; achenes about 1 mm 
long, obovoid, hardly compressed ; stigma short. 
Plants glabrous, scandent on tree, the upper internodes strongly zigzag : . 
petioles 3 to 6 mm long, the succulent lamina oblong-elliptic or oblong- 
lanceolate, 6. to 11 cm long, 21 to 38 mm wide, acute on both sides of the 
inequilateral base, the margins entire, the apical acumen obtuse and 
less than 1 cm long ; lateral veins at most barely visible, perhaps 6 to 8 
pairs. 
Luzon, Province of Laguna, Mount Maquiling, at an elevation of 200 m, Bur. 
Sci. 9687 {type), Bur. Sci. 9718 Robinson, gathered a few weeks apart from 
different plants epiphytic upon the same tree; these will be further duplicated by 
collections of students of the Philippine Agricultural College, made on the same 
occasions. Closely allied to the last, from which it may prove not to be separate.

Arbuscula, saepe epiphytica, glabra: inflorescentiis staminiferis 4 ad 
10 cm longis, cymoso-paniculatis ; eapitulis pistilliferis sessilibus, multi- 
floris, perianthii segmentis 4, fere usque ad basin liberis, oblanceolatis, 
circiter 1 mm long, ovarium subaequantibus : foliis modice petiolatis, 
oblongis ad oblanceolatis, basi inaequilatera acutis vel subobtusis, api'ee 
acuminatis, venis utrinque 7 ad 11.
