In the original description Bentham questions the generic 

 reference, a question which may still be seriously raised. 

 Werc not the genus Aster so all-embracing it would seem 

 better to separate this specics from it generically. It has no 

 stamens in the ligulate flowers, the styles are very short and 

 obtuse, the ligules are exceedingly small, and the whole habit 

 ■of leaf reduction and spiny phyllocladia is peculiar. 



ASTER Jamaicensis Less. [Erigeron Jamaicmsis L.) 



Santa Rosa, Depart. Santa Rosa, 3-4,000^ June 1892, Hcyde 

 ■& Lux 3, 363. This species of the "VVest Indies has also been 

 found occasionally in southern Mexico. I very much doubt 



its proper reference to Aster. 



CONYZA CORONOPIFOLIA HBK. (Incl. C. hirsuta HBK.) 

 — Chiul, Depart. Quiche, alt. 8,000^ April 1892, Heyde & 

 Lux 3,378. Exceedingly variable in foliage even on the 

 same plant. Our specimens represent the very hirsute form 

 with linear-lanceolate mostly entire (but frequently l- or 

 ;2-Iobed) leaves described by Kunth as C hirstita, and usu- 

 ally maintained as a distinct species. The two, however, 

 completely intergrade, and different branches of the same 

 plant will sometimes show all the differences between C. 

 coronopifolia and (7. hirsuta. 



MALLINOA, n. gen. of INULOIDE.E.?— Heads many-flowered, 

 homogamous, the flowers perfect: involucre campanulate, 

 with three or four series of imbricate striate bracts, the outer 

 ones shorter: corolla tubular, somewhat narrower below and 

 with a much constricted and easily separable base, 5-toothed, 

 the teeth hairy outside: anthers appendagcd, sagittate at 

 base: style-branches long, clavate and obtuse, the conspicu- 

 ous hairy appendages representing more than half the length: 

 achenes linear, 5-angIed, with aprominent indurated base and 

 constricted above to meet the distinct pappus ring which 

 bears numerous stout barbellate bristles as long as the corolla. 



Mallinoa corymbosa, n. sp.— Herbaceous, 40 to 50'" high, 



leafy and hairy at base, naked, smooth and corymbosely 

 branching above: leaves opposite, more or less woolly pubes- 

 cent on both sides, especially along the venation, rather long 

 petioled, ovate and dentate, obtuse, paler and conspicuously 

 reticulate beneath, 3 to 7'^" lon^ (blade), above reduced to 

 bracts: heads about 5""" high, solitary at the ends of the 

 «longated corymbose branches: involucral bracts smooth and 

 striate, oblong, the outer series somewhat shorter, the mner
