mm. long, standing at right angles to the margin, obtuse or sub- 

 acute at base, minutely puberulent beneath, especially along the 

 veins, glabrous above; veins prominent, light green, the lateral 

 ones arcuate-ascending, branched and reticulated, especially 

 toward the margin, one of the smaller marginal veins prolonged 

 into each denticulation; cymes terminal and lateral, spreading, 

 unbranched, 15-20 cm. long, very leafy, bearing 6-10 heads; 

 bracteal leaves resembling the cauline in shape and texture, or 

 varying to broadly oblong-elliptic in shape ; the lower approximat- 

 ing the cauline in size, the upper gradually reduced to half the 

 size, but always greatly exceeding the flowers; heads sessile, 

 single in the axils, about 34-47-flowered ; corollas white; involucre 

 hemispherical or broadly campanulate, 8-9 mm. high, in dried 

 specimens about 15 mm. broad; scales thinly puberulent, im- 

 bricated only at the base, straight or erect in bud, becoming 

 spreading or flexed in fruit, the outer lance-linear, subulate, the 

 inner linear-oblong, acuminate to a subulate tip; achenes smooth; 

 outer pappus white, 0.8 mm. long, inner series pale brown or 

 nearly white, 8 mm. long, minutely barbellate. 



Type, Shafer 13514, collected from high rocks in limestone hills, 

 vicinity of Sumidero, Province of Pinar del Rio, Cuba, August 2, 4, 

 1912, deposited in the Herbarium of the New York Botanical

 ing apparently the top of the plant, and the other two detached 

 lateral branches.

Shrubby, 1 m. high; stem erect, sparingly branched, finely

 bright green above, elliptic-oblong, 5-7 cm. long by 2-2.5 cm - 

 wide, acute, mucronate, entire or very obscurely and remotely 

 spinulose-denticulate, narrowed to an acute base, thinly puberulent 

 above, especially on the veins, finely and closely gray-tomentose 

 beneath ; veins elevated and prominent beneath, not conspicuously 

 reticulated; petioles 1-2 mm. long; inflorescence pyramidal, ter- 

 minal, of about 4-10 short, spreading or recurved cymes bearing 

 each 3-7 heads ; heads secund, sessile, about 21 -flowered; involucre 

 broadly campanulate or subhemispherical, 6-7 mm. high, its 

 scales appressed, closely imbricated, pubescent, especially near 

 the tip, outer scales ovate-triangular, acute and cuspidate, the
