1926] britton: west Indian plants 471 



short-peduncled or nearly sessile; corolla red, villous, slightly 

 curved, about 3 cm. long, its lobes about 6 mm. long. 



Heights of Aripo, Trinidad. (Trinidad Herbarium 9860, 



coll. Broadway, Jan. 10-26, 1922.) 



Chimarrhis microcarpa Standley, sp. nov. 



Branchlets stout, obtusely angulate, ochraceous, glabrous, 

 the internodes 5-13 mm. long; stipules lance-oblong, attenuate, 

 3 cm. long, thin, brown, glabrous, caducous; leaves opposite, 

 the petioles slender, glabrous, 2.5 cm. long; leaf blades elliptic, 

 11-19 cm. long, 5-8 cm. wide, acute, at base acute and decurrent 

 upon the petiole, membranaceous, glabrous, the lateral nerves 

 about 10 pairs, arcuate, laxly and irregularly anastomosing close 

 to the margin; inflorescences axillary, cymose-paniculate, halt 

 as long as the leaves, 4-5 cm. long and broad, many-flowered, 

 the peduncles slender, 3.5-5.5 cm. long, thinly puberulent, the 

 pedicels 1-2 mm. long; capsules subglobose, 2 mm. long, obtuse 

 at base, broadly rounded at apex, slender-costate, dark red- 

 brown, glabrous, crowned by the low persistent calyx. 



Type in the herbarium of the New York Botanical Garden, 

 collected at Maraval, Trinidad, in 1904 (I. Dannouse 6946). 



Because of the incompleteness of the available material, there 

 is some doubt as to the proper reference of this plant to Chimar- 

 rhis, but it agrees well with that genus in the characters exhibited 

 by the specimen studied. 



76. AN UNDESCRIBED TREE OF PORTO RICO 



Paralabatia portoricensis Britton & Wilson, sp. nov. 



A tree 15 m. or more high, the twigs clothed with appressed 

 ferruginous hairs. Leaves oblong-lanceolate, 6-1 1 cm. long, 

 2.5-4 cm. wide, acute or obtuse at the apex, rounded or some- 

 what acutish at the base; glabrous above except on the midvein, 

 loosely pubescent beneath with rather long whitish hairs, the 

 petioles about 1.5 cm. long; calyx-lobes 5, oblong-elliptic, 2 mm. 

 long, pubescent on the back; corolla-lobes broadly elliptic to oval, 

 1.5 mm. long, unappendaged; staminodes filament-like; ovary 

 2-celled. 



On limestone hills, northern Porto Rico. Type from Domin- 

 guito, near Arecibo (H. T. Cowles 702). 



Related to P. dictyoneura (Griseb.) Pierre, of Cuba, but dif- 

 fering in the pubescence of the petioles and lower leaf-surfaces.
