nerviis; cymis usque ad 6 cm longis, caulifloris vel e ramis 
vetustioribus; floribus 5-meris, minutissime bracteolatis, stami- 
nibus aequalibus. 
A glabrous shrub, the branches prominently 4-angled, each 
angle with a thick but narrow wing, pale-brownish, about 5 mm 
in diameter. Leaves opposite, distinctly peltate, coriaceous, 
ovate to oblong-ovate 10 to 13 cm long, 4.5 to 8 em wide, the 
apex sharply acuminate, base broadly rounded, 3- or 5-nerved, 
the inner. pair of nerves prominent, reaching the apex, the outer 
pair, when present, submarginal, evanescent below the apex; 
lateral nerves nearly obsolete on the lower surface, rather dis- 
- tinct on the upper; petioles 2 to 3.5 cm long attached to the 
leaf about.5 mm from its margin. Cymes up to 6 cm long, few- 
flowered, from the trunk or the larger branches, the minute 
bracteoles linear, 2 mm long or less, deciduous. Calyx cup- 
shaped or somewhat urceolate, about 8 mm long, the tube extend- 
ing about 2.5 mm above the ovary, truncate, undulate, 5- 
glandular. Petals 5, obliquely oblong-obovate, about 1.4 cm 
long and 7 mm wide. Stamens 10, equal; filaments 8 mm long; 
anthers lanceolate, acuminate, curved, 8 to 9 mm long, the dorsal

: A most characteristic species, at once distinguishable in the genus by its 
peltate leaves. According to Cogniaux’s arrangement of the species it falls 
in the group with Medinilla laurifolia Blume but is not closely allied to that 
species or to any other form known to me. 
MEDINILLA POLISENSIS sp. nov. 
Species M. clementis affinis, differt foliis multo minoribus, 
usque ad 13 cm longis, basi rotundatis, 5-plinerviis, antheris 
majoribus. 
A stout vine climbing in trees, glabrous except the setose 
nodes. Branches terete, somewhat reddish-brown, the younger 
branchlets obscurely 4-angled to prominently 4-winged, the in- 
ternodes 2 to 5 cm long. Leaves opposite, coriaceous, oblong 
to oblong-elliptic, 8 to 13 em long, 2 to 4 cm wide, base rounded 
or obtuse, apex acuminate, the upper surface pale when dry, 
shining, the lower somewhat brownish, the base prominently 5- 
plinerved, sometimes with an additional fainter basal pair, the 
inner pair leaving the midrib at from 2 to 3 cm above the base 
and reaching the apex where they anastomose with the midrib,
