[vol. 53 



pilose with slender, closely appressed hairs, more densely pilose 

 along the nerves, the costa salient, the lateral nerves very 

 prominent, 5 or 6 pairs, nearly straight, ascending at an angle 

 of 45 , arcuately anastomosing near the margin; inflorescence 

 terminal, subsessile, i-flowered, subtended by lanceolate to 

 rhombic-ovate bracts, these longer than the capsule, appressed- 

 pilose; capsule subglobose, 5 mm. long, densely appressed-pilose, 

 the 4 persistent calyx-lobes (imperfect) oblong, 7 mm. long, 

 densely appressed-pilose outside. 



Type in the herbarium of the New York Botanical Garden, 

 collected on rocky banks of Arroyo Bayaja, Sierra Maestra, south 

 of Nagua, Oriente, Cuba, August 8, 1922 (E. L. Ekman Z4759). 



The foliage of this plant is suggestive of R. correifolia Griseb., 

 but the form of the inflorescence is unlike that of any of the 

 Cuban species of Rondeletia.

 Gravisia aripensis N. E. Brown, sp. nov. 



Leaves 60-75 cm - or more long, 4^-5 cm. broad, broadly 

 strap-shaped, concave; sides parallel up to about $-6 cm. below 

 the apex, where they incurve to an acute and shortly mucronate 

 point; margins armed with small horizontally spreading pale 

 brown (? green when alive) prickles 1 mm. long and 3-5 mm. 

 apart; surface glabrous, very minutely punctate (not lepidote). 

 Scape 13-14 cm. long in the only specimen seen, 7 mm. thick, 

 clothed with light brown wool and bearing two glabrous sheath- 

 ing acute bracts 5-7 cm. long, and terminating in a dense sub- 

 globose inflorescence 7-8 cm. long and 7-8 cm. in diameter, com- 

 posed of 4-5 spherical bright pink flower-heads, each about 4 

 cm. in diameter and sessile in the axil of a large elliptic obtuse 

 mucronate pink outer bract 5-6 cm. long and 4-5 cm. broad. 

 Flowers numerous in each cluster or head. Bracts about 3-3}^ 

 cm. long, 10-15 mm. broad, ovate-lanceolate, acute, tipped with 

 a spine 3-4 mm. long, slightly woolly or becoming glabrous. 

 Sepals 15 mm. long, spine-tipped, the lower two-thirds having 

 unequal membranous inrolled margins, one margin about 3 mm. 

 broad and the other 1 mm. broad and more acutely narrowed 

 into the spine than the broad margin, woolly. Petals not seen 

 in perfect condition, but apparently about as long as the sepals 

 and lanceolate. Stamens about three-fourths as long as the 

 petals, absent in two flowers examined; anthers 3^ mm. long, 

 versatile, oblong, with a blunt mucro. Style rather shorter 

 than the stamens; stigma entire.
