CHAPTALIA. 195 



0. SUBCORDATA. Large plants, without rootstock but with 

 J to 1 inch of leafy stem above ground : leaves ample, 5 to 8 

 inches long, very thin, glabrous above, thinly hoary-tomentose 

 and permanently so beneath, of an unusual type of the lyrate 

 in form, a large subcordate-oval terminal part often 4 inches 

 long and 2 in breadth occupying the upper half, below this a 

 broadly winged petiole, all the margins lightly and remotely 

 crenate and with a rather close denticulation everywhere : scape 

 usually solitary, not dilated under the involucre, this not large, 

 many-bracted and imbricate : immature achenes short-beaked. 



Islands of Porto Rico and St. Croix, the type Ricksecker's 

 n. 447 from St. Croix, as in U. S. Herb,, Percy Wilson's n. 40 

 from Porto Rico evidently the same. 



0. FALLAX. Rootstock obsolete ; leaves many, 3 to 4 inches 

 long, oblanceolate, somewhat spatulately so, acutish, entire or 

 faintly undulate, or obscurely crenate, no denticulation obvious 

 deep green and glabrous above, densely and permanently white- 

 tomentose beneath : scapes several, slender, naked, 8 or 10 inches 

 high, abruptly dilated under the narrow involucre; bracts of 

 this narrowly subulate and subulate-linear, many and much 

 imbricated : achenes with a distinct slender beak. 



Vicinity of Baracoa, Cuba, Jan., 1902, Pollard & Palmer, 

 n. 86 as in U. S. Herb. The collectors referred this to the 

 Floridian C. iomentosa, evidently looking to the leaves only. By 

 its involucre and achenes it is unmistakably of the other group, 

 namely that of Leria, and not a proper Chaptalia. 



C. PKiMULAOEA. Rootstock not thick, upright, somewhat 

 tapering and root-like : leaves many, narrowly oblanceolate, 

 mostly 3 to 6 inches long, thin, glabrous above, beneath densely 

 white-tomentose, but the numerous feather veins somewhat 

 glabrate and conspicuous, the outline in no degree lyrate, the 

 whole margin lightly repand-crenate one retrorse tooth at base of 

 each crenature, the apex cuspidate-mucronate : scape usually 1 

 only, 5 to 8 inches high, very slender, naked, abruptly enlarged 

 under the small involucre; bracts of this subulate as to the 

 outer, the inner narrowly linear, all flocculent: achenes scab- 

 rous, the slender beak nearly as long as the body.
