or obscure species of Plants. 42 '3 



Sir W. Hooker's character comprehends both ; but Decandolle's is 

 more limited, so much so, indeed, as to exclude, perhaps, all the 

 species he refers to it. In Lindley's Nat. Syst. of Botany, p. 443, 

 I separated B. glandulosus under the name of Eriopappus, propo- 

 sing to retain Blepharipappus for B. scaber. About the same time 

 that my genus was published, or perhaps previously, Fischer and 

 Meyer defined the same under the name of Callichroa ; and indeed, 

 so far as I can judge by the description, Blepharipappus glandu- 

 losus, Hook. Madaroglossa heterotricha, D. C. Prod. v. p. 694, and 

 my Eriopappus glandulosus, are scarcely distinguishable as species 

 from Callichroa plalyglossa, F. and M. To Blepharipappms I would 

 refer Madaroglossa hieracioides, and M. angustifolia of Decandolle. 

 In Madaraglossa the achenium of the ray is said to be glabrous, 

 and the styles of the disk florets included. The latter is characte- 

 ristic of what I consider the true species of Blepharipappus, and the 

 former of Eriopappus or Callichroa ; but indeed Mad. angustifolia 

 is expressly said to have the achenia of the ray villous. 



Lasthenta, Cass. fCompositse.^) 

 This genus, as defined by Decandolle, requires some elucidation. 

 In his character, which it is unnecessary to quote at length, the 

 capitulum is said to be nearly homogamous, that is, without any 

 conspicuous ray, the female florets being small and tubular ; the in- 

 volucre to be 5-8-1 5-toothed, and the pappus of 5-10 paleae, or 

 wanting ; while he adds, that it differs from Gamolepis by the capi- 

 tulum being nearly homogamous, and by having a paleaceous pappus. 

 Three species are described ; one with a paleaceous pappus and 

 an obscure ray : this (Z,. obtusifolia, Cass.) which is the type of the 

 genus, is the Rancagua of Poeppig, Hymenatherum of Lessing, 

 (but not of Cassini,) and Coilopodium Chilense of Decandolle, Prod, 

 v. p. 642, (noticed under Hymenatherum Kunthii) : to it the whole 

 generic character given by Decandolle applies, with the exception 

 of the involucre being 15-toothed, and a pappus of 5 or no paleae. 

 Another species is L. glaberrima ; of this the ray is not mentioned, 

 but the involucre is said to be 15-toothed, and the pappus of 5 pa- 

 leae. What plant Decandolle has had in view, and which he re- 

 ceived from the Horticultural Society, I cannot determine, but what 

 I have received from Professor Lindley has a large ray, and is the 

 same with Burrielia gracilis of Decandolle ; while that figured in 

 the Botanical Register seems to have also a large ray, but no pap- 

 pus, and to be either a variety of or closely allied to L. glabrata, 

 Lindl. The third species, L. glabrata, mentioned by Decandolle,
