 among bowlders on forested slopes at low altitudes. 



A species similar and distinctly allied to Begonia urda- 

 neteyisis Elm. but with larger leaves, quite different indumentum, 

 and narrower stipules. 



THYMELAEACEAE 

 GYRINOPSIS Decaisne 

 GYRINOPSIS ACUMINATA sp. nov. 



Frutex, floribus exceptis glaber, foliis anguste lanceolatis ad 

 lanceolatis, 12 ad 20 cm longis, tenuiter acuminatis, basi cunea- 

 tis, nervis numerosis, dense dispositis ; floribus axillaribus, fasci- 

 culatis, leviter pubescens, circiter 5 mm longis; capsulis circiter 

 1 cm longis, rugosis, obovoideis. 



A shrub or small tree, entirely glabrous except the flowers, 

 the branchlets usually reddish-brown. Leaves narrowly lan- 

 ceolate to lanceolate, 12 to 20 cm long, 2.5 to 4.5 cm wide, nar- 

 rowed to the cuneate base and to the slenderly acuminate apex, 

 greenish or olivaceous and shining v/hen dry. The primary 

 lateral nerves scarcely distinguishable from the densely arranged 

 secondary ones; petioles 5 mm long or less. Flowers axillary, 

 fascicled or in very greatly reduced cymes, their pedicels about 

 2.5 mm long. Perianth slightly pubescent, about 5 mm long, 

 the lobes 5, oblong, obtuse, about 1.5 mm long. Stamens 10 in 

 a single row near the throat, 5 alternating anthers slightly longer 

 than the others. Ovary oblong-ovoid, narrowed upward, pu- 

 bescent ; style very short. Capsules yellowish, rugose when dry, 

 1 cm long or less, 2-valved, usually containing a single, sub-

This species is closely allied to Gyrinopsis brachijantha Merr., 

 from which it is distinguished by its longer, slenderly acuminate, 

 diff"erently shaped leaves.
