Miq. present considerable variation in the size of the leaves, but the vena- 
tion and characters of the inflorescence, the flowers, and the fruits are 
essentially identical with material from Ceylon ( Thwaites C. P. 171b), the 
Malay Peninsula, Singapore, and Borneo. The leaves of the Philippine 
specimens average somewhat wider than in our extra-Philippine material. 
Chasalia obscurinervia Elm. Leafl. Philip. Bot. 3 (1911) 1033, based on 
Elmer 11200 from Mindanao, a specimen with immature fruits, is probably 
identical with Chasalia larida Miq. Comparing Elmer 11200 with Thwaites 
C. P. 171b I can detect no constant differential characters that would 
lead me to consider the two specimens specifically distinct; they are not, 
however, directly comparable as Elmer’s specimen has immature fruits, 
while Thwaites’s specimen is in flower. Chasalia expansa Miq., to which 
Mr. Elmer compares his species, is, according to Koorders, a synonym of 
Psychotria montana Blume. 
STREBLOSA Korthals 
STREBLOSA AXI LLI FLORA sp. nov. 
Frutex vel suffrutex parvus, inflorescentiis axillaribus minute 
hirsutus; foliis membranaceis, oblongis ad oblongo-ellipticis, oli- 
vaceis, usque ad 15 cm longis, longe petiolatis, utrinque aequaliter 
angustatis acutisque, nervis lateralibus utrinque circiter 15; in- 
florescentiis numerosis, axillaribus, quam petiolo brevioribus, 
subcymosis, brevissime pedunculatis ; floribus minutis, haud 2 
mm longis, bracteolatis ; fructibus ellipsoideis, 2 mm longis, 
longitudinaliter sulcatis ; pyrenes plano-convexis, dorso acute 
3-carinato, albumine aequabile. 
A shrub or undershrub (size not indicated by the collector), 
nearly glabrous except the inflorescence which is pubescent with 
scattered, short hairs. Branches terete. Leaves membrana- 
ceous, olivaceous when dry, slightly shining, oblong to oblong- 
elliptic, 9 to 15 cm long, 3.5 to 5.5 cm wide, subequally narrowed 
to the acute base and apex, the lower surface very obscurely pu- 
berulent at least on the nerves; lateral nerves about 15 on each 
side of the midrib, distinct, somewhat curved, anastomosing; 
petioles 3 to 4 cm long ; stipules up to 8 mm long, cleft nearly to 
the base into two, lanceolate, acuminate segments. Inflorescence 
subcymose, axillary, short-peduncled, 2 cm long or less, sparingly 
hirsute with short hairs, the branches few, the flowers and fruits 
rather densely crowded; bracts oblong-ovate, up to 1.8 mm long, 
slightly pubescent. Flowers 2 mm long or less, the calyx slightly 
pubescent, 5-toothed. Stamens 5; anthers 0.5 mm long. Fruit 
ellipsoid, about 2 mm long, slightly hirsute, longitudinally ridged, 
the pyrenes plano-convex, the back distinctly and rather sharply 
3-ridged, seeds not at all ruminate.
