An interesting species apparently not rare in the higher 

 mountains of Hispaniola. The specimens cited above agree 

 exactly with each other and with the type of Proustia do- 

 mingensis Spr. in the Prodromus Herbarium. The type 

 specimen of Lepidaploa huxifolia Cass, has not been seen. 

 The good description of Cassini agrees perfectly with the 

 species as here understood. 



Gleason in his »Revision » and in his »Studies » evidently 

 has another plant in mind when describing V. huxifolia. The 

 characteristics »Achenes pubescent; outer pappus conspi- 

 cuous, its scales much broader than the wliite bristles of the 

 inner series» (Gleason, 1913, p. 327) clearly do not apply 

 to our V. huxifolia, of which Cassini says: »Les ovaires sont 

 glabres . . . leur aigrette est roussatre, double: I'exterieur 

 courte, peu distincte, composée de squamellules inegales, 

 filiformes-laminées, subulées, denticulées ». Which species 

 Gleason has in mind, I cannot decide; most probabty it is 

 a new one. He has, however, genuine F. huxifolia (Cass.) 

 Less, at hand, but describes it as a new species, F. montana 

 Gleason.
