of the Galapagos Archipelago. 211 



The species of Scalesia form a very natural genus, and all those now to be 

 described agree in every essential particular with the generic character, drawn 

 up by Arnott from an examination of S. atractyloides alone. The flowers of 

 the ray in some have ligulate corollas, but they are neuter, and such species 

 are here grouped together. The division of the style is a variable character ; 

 it has long arms in some of the flowers and is very short in others. Judging 

 by Mr. Darwin's excellent specimens, this and the following species appear 

 very distinct from one another. The habit of the present is rather different 

 from the rest.

Hab. James Island, Charles Darwin, Esq. 



Rami ultimi simplices, crassitie fere pennae anserinae, glabri, striati, superne pubescentes, ad 

 apices villosi, gummiferi, e lapsu foliorum cicatricati. Folia patentia, in ramis terminalia, 

 basi cuneata, apices versus longe attenuata, plana, nervosa, moUiter pubescentia, 3-4 

 unc. longa, petiolis gracilibus, ^-|-uncialibus, interdum ut folia juniora albo-sericeis. 

 Pedunculi axillares, 3 unc. longi, crassitie pennae corvinae, sericei v. pubescentes. Ca- 

 pitula multiflora, circa | unc. diametro, latiora quam lata, basi truncata, pedunculo 

 intruso. Involucri squamae late obovatae, acutae, pubescentes v. sericeae. Corollae in- 

 volucro longiores, tubo puberulo ; antheris f exsertis. 



A very handsome species.
