 shortly acuminate at the apex, the apex acutish, widest in the middle, above shining 

 and almost glabrous, below densely tomentose, thin; inflorescence on a slender 

 peduncle 20 to 30 mm. long, shortly pyramidal, the branches slender; perianths 

 sessile or on very short pedicels, ellipsoidal, 5 mm. long, shortly but distinctly atten-

The writer has seen no material of this species. The description is adapted from 

 that of Doctor Heimerl. 



2. Neea pittieri Standley, sp. nov. 



Branches stout, roughened, glabrous; leaf blades ovate to elliptic-oblong, 17 to 24 

 cm. long and 11 to 13 cm. wide, sharply caudate at the apex, with a narrowly trian- 

 gular and very acute tip 15 to 20 mm. long, rounded or obtuse at the base and some- 

 what unequal, glabrous, thin, with conspicuous lateral veins, on a petiole 10 to 16 mm. 

 long; inflorescence an open corymb 11 cm. broad, with stout, divaricate, puberulent 

 branches, on a stout peduncle 7 cm. long; staminate flowers about 9 mm. long, tubu- 

 lar or ellipsoidal, with 5 ovate, acuminate teeth at the mouth, on pedicels about 2 mm. 

 long; stamens 5 to 10, very unequal, the longest filaments 4.5 or 5 mm. long, glabrous, 

 anthera 1.5 to 2 mm. long. 



Type in the U. S. National Herbarium, no. 578028, collected on the mountains about 

 the Valley of Tuis, Costa Rica, at an altitude of 1,000 meters, by Mr. H. Pittier (no. 

 16097). The very large and wide leaves with their caudate apices are very different 

 from those of any of the other species treated here, while the flowers are considerably 

 larger.
