long*. Stamens many-seriate, subequal, their filaments up to 1 cm in length; 
anthers elliptic, longitudinally 2-celled, 1 to 1.2 rpm long, opening by lon- 
gitudinal slits. Ovary inferior, 4-celled; ovules several seriate, axile; style 
slender, about 6 mm long. 
The discovery of a third species of this typically African genus, in the 
Philippines, while unexpected, is by no means the only case of special 
extra-African distribution presented by the Philippine flora. We have in 
the Philippines one representative of the almost exclusively African genus 
Angraecum (A. philipjnnense Ames), and one representative of the almost 
exclusively African and Madagascar genus Erythrophloeum ( E . densiflorum 
Merr.).

Arbor circiter 15 m alta, glabra, ramis ramulisque teretibus ; 
foliis oppositis, coriaceis vel subcoriaceis, in siccitate olivaceis 
vel pallide brunneis, ellipticis at oblongo-ellipticis, usque ad 9 
cm longis, breviter obtuseque acuminatis, basi acutis, tenuiter 
triplinerviis, subtus parce puncticulatis, nervis lateralibus utrin-

brevissime pedicellatis, circiter 2.5 cm diametro, calycis lobis 
subpersistentibus, patulis, glandulosis, orbiculari-ovatis, rotun-

A tree about 15 m high, entirely glabrous, or the inflorescence 
very obscurely pubescent. Branches and branchlets terete, 
smooth, pale or brownish when dry, slender. Leaves opposite, 
coriaceous or subcoriaceous, olivaceous or pale-brownish when 
dry, shining, the lower surface sparingly puncticulate, paler than 
the upper, 5 to 9 cm long, 3 to 4.5 cm wide, elliptic to oblong- 
elliptic, subequally narrowed to the acute base and to the shortly 
blunt-acuminate apex, the base 3-plinerved, the nerves slender, 
distant about 5 mm from the margins, continuing to the apex; 
lateral nerves 6 to 8 on each side of the midrib, slender, anas- 
tomosing with the marginal nerves, the reticulations obscure; 
petioles 4 to 5 mm long. Flowers white, fragrant, axillary or 
in the axils of fallen leaves, solitary or fascicled, their pedicels 
short, stout, about 1.5 mm long, jointed to the pseudo-stalk; 
bracteoles ovate, slightly pubescent, 1.5 mm long. Calyx-tube,
