special branches, these branches simple or branched near their apices, 
up to 18 cm long, the apical portions thickened, cylindric, marked by 
numerous scars, the panicles numerous, entirely glabrous, slender, 5 to 8 
cm long, all parts marked with linear or punctate glands, the panicles 
2-pinnate, the flowers racemosely arranged on the ultimate branchlets. 
Staminate flowers 5-merous, their pedicels 2 to 3 mm long. Calyx 1.6 
mm in diameter, glandular-punctate, glabrous, the lobes ovate, obtuse, 
united for one-half their length. Corolla 3 mm in diameter, glandular- 
punctate, the lobes ovate, obtuse, united for one-half their length. 
Anthers less than 0.5 mm long, sessile. Rudimentary ovary wanting. 
Pistillate flowers and fruits unknown. 
MINDANAO, Province of Surigao, in the valley of the Agusan River near Amparo, 
in forests at an altitude of about 130 m, For. Bur. 7616 Hutchinson, August 26, 
1907 (type).. NeGros, Mount Marapara, For. Bur. 13688 Curran, with immature 
flowers. 
A species similar in vegetative characters to Discocalya effusa Mez, but with 
very much larger leaves and much longer petioles, the inflorescence also entirely 
different. It is apparently most closely allied to D. montana Elm., but is quite 
distinct from that species. 
Discocalyx macrophylla sp. nov. 
Frutex erectus, glaber, circiter 2 m altus; foliis-alternis, elliptico-ovatis 
vel elliptico-oblongis, subcoriaceis, in sicco nitidis, usque ad 31 cm 
longis, valde denticulatis, basi rotundatis, petiolo usque ad 15 cm longo; 
floribus in paniculis brevibus congestis, 5-meris, glabris. 
An erect shrub about 2 m high, the ultimate branches very stout, 
brown, 1.5 to 2 cm in diameter. Leaves alternate, or somewhat crowded 
at the apices of the branchlets, elliptic-ovate to elliptic-oblong, about 30 
cm long, 12 to 16 cm wide, glabrous, subcoriaceous, shining, the lower 
surface obscurely and minutely glandular-punctate, somewhat paler than 
the upper one, the apex very shortly and obscurely bluint-acuminate, the 
base broad, rounded, the margins strongly and densely denticulate except 
at the very base where they are entire; nerves 25 to 30 on each side of 
the midrib, very prominent, anastomosing, the reticulations distinct on 
both surfaces; petioles stout, dark-brown, about 15 cm long.  Inflores- 
cence on special, leafless (or with one very much reduced leaf) branches, 
40 cm long or less, from just below the leaves, the apex thickened and 
bearing one or several short, dense panicles which doubtless become more 
or less diffuse in anthesis. Flowers (in bud, and immature), 5-merous, 
all parts glandular-punctate, glabrous, the anthers sessile. Immature 
fruit globose, 3 mm in diameter. 
Luzon, Province of Cagayan, near San Vicente, in forests, at sea level, Vor. 
Bur. 17237 Curran, March 8, 1909. 
A very characteristic species, distinguishable by its very large and long-petioled 
leaves, as well as by the very long, specialized branches that bear the inflorescences. 
It is unquestionably allied to Discocalyx effusa Mez, although quite different from
