bracteoles minute, linear, 1 to 2 mm long. Calyx urceolate, 
truncate, about 5 mm long. Petals 4, obliquely obovate, about 
13 mm long. Stamens 8, equal; filaments 5.5 mm long; anthers 
lanceolate, acuminate, 5.5 mm long, the dorsal appendage slender, 
0.8 mm long, the anterior appendages stout, curved, blunt, 1

Apparently most closely allied to Medinilla subsessilis Merr., of Luzon, 
differing in its more numerously nerved leaves, longer petioles, nearly 
glabrous nodes, and much smaller bracts. It resembles Medinilla negro- 
sensis Merr., M. confusa Merr., and M. myriantha Merr., but differs from 
all, among other characters, by its much larger flowers. 
16. MEDINILLA NEGROSENSIS sp. nov. 
Frutex glaber, ramis ramulisque 3- vel 4-angulatis, nodis dense 
setosis; foliis oppositis, breviter petiolatis, ovatis ad elliptico- 
oblongis, usque ad 20 cm longis, basi acutis vel rotundatis, 7- vel 
9-plinerviis, apice distincte acuminatis; paniculis terminalibus, 
foliis subaequilongis vel longioribus, diffusis, multifloris, ramis 
verticillatis ; floribus 4-meris. 
A shrub, erect or scandent, glabrous, the branches and branch- 
lets distinctly 3- or 4-angled, the nodes rather densely setose. 
Leaves opposite, ovate to elliptic-oblong, coriaceous, somewhat 
shining, of about the same color on both surfaces when dry, 
12 to 20 cm long, 4.5 to 9 cm wide, the base rounded or acute, 
the apex distinctly and rather slenderly acuminate; nerves 7 
to 9, as prominent as the midrib, all leaving the midrib above 
the base, the inner pair at from 1.5 to 3 cm above the base, 
the inner two pairs reaching the apex of the leaf, reticulations 
obsolete; petioles 6 to 10 mm long. Panicles terminal, as long 
as or longer than the leaves, peduncled, flower-bearing in the 
upper part, the branches verticillate, 5 to 8 at each node, spread- 
ing, the lower ones up to 7 cm in length, many-flowered, the 
verticils distant. Flowers 4-merous, ebracteolate, or bracteoles 
very minute and deciduous, the pedicels 3 to 8 mm long. Calyx 
broadly urceolate or urceolate-campanulate, about 3 mm long, 
truncate. Petals 4, obliquely obovate, 7 mm long. Stamens 8, 
equal; filaments about 3.5 mm long; anthers lanceolate, 4 mm 
long, acuminate, dorsal spur slender, 0.5 mm long, the anterior 
appendages stout, curved, obtuse, 1 mm long.
