special branches, these branches simple or branclied 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

 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.

 in forests at an altitude of about 130 m, For. Bur. 1616 Hutchinson, August 26, 

 1907 (type). Negkos, Mount Marapara, For. Bur. 13688 Curran, with immature 

 flowers. 



A species similar in vegetative characters to Discocalyx effitsa Mez. but with 

 very nuich larger leaves and much longer petioles, the inflorescence also entirely 

 difTerent. It is apparently most closely allied to D. montana Elm., but is quite 

 distinct from that species. 



Discocalyx macrophylla sp. nov. 



Frutex crectus, giaber, 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 tlian 

 the upper one, the apex very shortly and obscurely bhmt-acuminate, the 

 base broad, rounded, the mai'gins strongly and densely denticulate except 

 at the very base where they are entire; nerves 25 to 30 on each side of 

 the midrib, veiy 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 tlie 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, liniuature 

 fruit globose, 3 mm in diameter.
