younger parts; leaves alternate, linear or linear-filiform, 9-25 

 mm. long, 0.5-1.5 mm. wide, cuspidulate, short-petioled, 1- 

 nerved, the margins often inflexed; peduncles 5-10 mm. long; 

 racemes loosely many-flowered, the axis sometimes becoming 

 25 cm. long; bracts subulate, 1.5 mm. long, caducous; pedicels 

 glabrous, 1.5-2 mm. long; sepals bearing 3-6 pairs of stipitate 

 glands, sometimes also ciliolate with eglandular hairs toward 

 apex, the upper sepal 2 mm. long, the lower sepals (connate 

 nearly to apex) 1.5 mm. long; wings magenta-purple, broadly 

 and obliquely cuneate-obovate, 3.8-4.5 mm. long, 2.8-3.2 mm. 

 wide, subsessille or short-clawed, emarginate at apex, glabrous, 

 about 5-veined, the veins loosely anastomosing, not at all 

 prominulous; upper petals magenta-purple; keel yellow-tipped, 

 becoming 4 mm. long; capsule 3.8 mm. long, 2.4 mm. wide, 

 slightly shorter than the mature wings; seed densely pilose, 

 2.8 mm. long; aril sparsely pubescent on the sides, 0.8 mm. high. 



Sabana del Cerro, near Cerro Pelado, between Zarzal and 

 Nagua, Oriente, July, 1922 {Leon 10860; type No. 1,049,889, 

 U. S. National Herbarium). 



Nearly related to Poly gala cubensis Chod., which is an annual 

 with shorter sepals (1. 1-1.3 mm - l° n g)> an d somewhat smaller 

 wings shorter than the capsule. In its slender but evidently 

 perennial root resembling P. Wrightii Chod., which is densely 

 incurved-puberulous and has the sepals ciliate with eglandular 

 hairs. Much more material of the Cuban representatives of 

 this group (section Adenotricha of subgenus Hebeclada) must be 

 accumulated before the specific characters can be established 

 satisfactorily. 



Maytenus saxicola Britton & Wilson, sp. nov. 



A glabrous shrub, 4 m. high, with rather stiff, somewhat 

 flexuose twigs. Leaves elliptic to elliptic-ovate, rigid-coriaceous, 

 3-6 cm. long, 1.5-3.3 cm. broad, obtuse or rounded at the apex, 

 a cute at the base, dark green above, paler beneath, the midvein 

 elevated on both sides, the lateral veins often rather indistinct, 

 the margin minutely crenulate; petioles 5 mm. long or less; 

 pedicels slender, up to 7 mm. long; capsule globose-obovoid, 

 8 mm. long, 7-8 mm. in diameter. 



On rocks, Sierra Maestra, Oriente {Leon, Clement and Roca

Rhamnidium bicolor Britton & Wilson, sp. now 



A shrub, with slender puberulent twigs. Leaves opposite, el- 

 liptic or ovate-elliptic, 8 cm. long or less, repand-crenate, mem-
