Britton: Studies of West Indian plants — XI 39 



3-10 cm. long, dark-green, sparingly pubescent and somewhat 

 glandular-granuliferous above, paler and somewhat fuscous and 

 densely short-villous, almost subvelutinous, beneath; racemes 

 3-6 cm. long, 5-10-flowered; peduncles and pedicels densely 

 pubescent and glandular, slightly prickly; sepals lanceolate, 

 acuminate, 5-6 mm. long, glandular and pubescent without, 

 grayish-tomentose within; berry about I cm. long and 7-9 mm. 

 thick; drupelets many, glabrous. 



Type collected on the top of Pico Turquino, Oriente, Cuba, 

 July 23, 1922, Leon 10755 (New York Botanical Garden); also 

 at an altitude of 1600 m. on the same mountain, 10756. 



R. turquinensis is a member of the Adenotrichi, differing from 

 R. costaricanus and R. adenotrichos in the narrower lanceolate 

 long-acuminate, instead of broadly ovate, abruptly acuminate 

 leaflets; from R. Vera-Crucis in the more dense pubescence and 

 the texture of the leaves. It is more closely related to R. 

 irasuensis and R. miser. In habit, leaf-form, and pubescence it 

 resembles the former, but the inflorescence is mostly simple, the 

 sepals narrower, and the drupelets perfectly glabrous; neither 

 have any 5-foliolate leaves been seen. From R. miser it differs 

 in the shorter sepals and the thicker leaflets, with shorter petioles, 

 more numerous and more prominent lateral veins, and much 

 closer serrations. 



Polygala scabridula Blake, sp. nov. 



Virgate leafy shrub 2-3 m. high, the branches erect, his- 

 pidulous. Petioles hispidulous, 2 mm. long; leaf blades obo- 

 vate, 1. 3-1. 8 cm. long, 9-12 mm. wide, broadly rounded at apex, 

 rounded or cuneate-rounded at base, coriaceous, scabrid-his- 

 pidulous above with persistent ascending hairs, similarly pu- 

 bescent beneath; racemes axillary, the axis few-flowered, about 

 1 mm. long, the peduncle obsolescent; pedicels glabrous, 1.2 

 mm. long; flowers immature; sepals deltoid-ovate, ciliolate, 

 obtuse, i.i mm. long; wings similar, 1.4 mm. long and wide; 

 keel ciliate, otherwise subglabrous, 2.5 mm. long; capsule sub- 

 quadrate, rather broadly margined, slightly wider at the apex, 

 ciliolate, otherwise glabrous, 6 mm. long, 8.5 mm. wide, lobed 

 for about 1/3 its length; seed ellipsoid, sparsely pubescent, 4 

 mm. long; aril orange, 1.8 mm. deep, with repand lateral margin, 

 the dorsal lobe 1 mm. long. 



Sabana de Motembo, Santa Clara, August 9-10, 1920 {Leon 

 and Loustalot 9333). 



This species is related to Polygala portoricensis (Britton) 

 Blake, of Porto Rico, which has larger emarginulate leaves, 

 and a smaller, less deeply lobed capsule.
