116 Britton : Cuban Plants New to Science 



persistent; receptacle foveolate; rays white; ligule linear, i. 6-1.8 

 mm. long; achenes ellipsoid-cuneiform, 0.5 mm. long, hirsute 

 with short hairs ; pappus about twice as long as the achene. 



Upper Guama River, Sevilla Estate, near Santiago, Oriente 

 (Taylor 181), forming moss-like patches. 



Erigeron Earlei Britton & Wilson, sp. nov. 



Loosely hirsute ; stems solitary or few together, slender, erect, 

 about 2.5 dm. high, few-branched above. Leaves membranous, 

 the basal and lower ones spatulate or oblanceolate, 3-4.5 cm. 

 long, obtuse or rounded at the apex, coarsely crenate, narrowed 

 into margined petioles or sessile, or the lowest with slender pe- 

 tioles 1-2 cm. long, the uppermost oblong, acute, entire, 1-2 cm. 

 long, sessile ; heads several, slender-peduncled, the peduncles 

 bearing 1-3 linear or lanceolate bracts 1-4 mm. long; involucre 

 subhemispheric, 4 mm. high, its bracts in about 2 series, linear- 

 lanceolate, acuminate, the outer ones pilose, somewhat shorter 

 than the inner, all renexed in age and persistent ; rays white ; 

 ligule linear, 1.5-1.7 mm. long; achenes oblong-ellipsoid, 0.6 mm. 

 long, hirsute ; pappus 2-3 times as long as the achene. 



Rocky river-bed, Hanabanilla Falls, Trinidad Mountains, 

 Santa Clara (Britton, Earle & Wilson 4843). 



Borrichia cubana Britton & Blake, sp. nov. 



Shrub, oppositely branched, the stem and branches sparsely 

 appressed-pilose, glabrate. Leaves opposite, the blades oblanceo- 

 late to spatulate-obovate, 3-3.8 cm. long, 5-1 1 mm. wide, mucro- 

 nate-apiculate at the rounded apex, cuneately narrowed into the 

 petiole, entire or sparsely spinulose-toothed below, coriaceous, 

 obscurely triplinerved, canescent-lanate both sides ; petioles nar- 

 rowly margined, broadened and connate at base, 6-10 mm. long ; 

 peduncles terminal, rather sparsely appressed-pilose, thickened 

 above, 5-7 cm. long; heads 2.2 cm. wide; disk subglobose, I 1.2 

 cm. thick ; involucre about 4-seriate, graduated, 8-9 mm. high, 

 the outer phyllaries deltoid-ovate, acute and weakly mucronulate, 

 with indurated base and spreading canescent-lanate apex, the 

 inner broader, ciliate, otherwise subglabrous, with cuspidate- 

 mucronate spreading tips about 2 mm. long; rays about 15, yel- 

 low, oval, 6 mm. long; disk-corollas yellow, slender, glabrous, 5.8 

 mm. long; pales similar to the outer phyllaries, broad, indurated, 

 ribbed, with erect stiffly mucronulate tips about 1 mm. long; 

 achenes quadrangular, black, glabrous, 3 mm. long; pappus a 

 thickened angulate crown 0.8 mm. long.
