tus incano-tomentosis, floribus laxe paniculatis, involucri squamis scariosis obtusissimis 

 inferioribus albo-tomentosis. 



Caulis subpedalis, ramosus, arachnoideo-tomentosus. Folia digitalia, basi semiamplexicaulia, pro- 

 funde pinnatifida, segmentis angulato-laciniatis, laciniis superioribus elongatis, attenuatis. Involucrum 

 hemisphamcum, imbricatum, squamis oblongis, exterioribus obtusis, albo-lanuginosis ; interioribus acutis, vel 

 etiam acurainatis, scariosis, margine subciliatis. Flosculi purpurei, bilabiati, exteriores radiati, labio extenore 

 oblongo patente, interiore 5-plo minore, recurvato, bipartito, laciniis linearibus ; interiores labio extenore 

 parvo, lineari, erectiusculo, interiore duplo minore, recurvato, bipartito. Beceptaculum punctatum, nudum. 

 Achenia (vix matura) oblonga, basi attenuata, siccitate rugosa. Pappus subplumosus, sessilis, albus. 



Hab. Conception.— We believe that this belongs to the Leucceria of Lagasca, but we do not find any 

 trace of palese among the radiate florets.

Hab. Valparaiso.— In our plant the root is annual, and from the crown of it issue several short, usually 

 one-flowered stems. The leaves are narrowly spathulate, obtuse, and very sharply toothed. The figure given 

 by De Candolle bears hardly any resemblance to our specimens, and we should not have had the least idea ot 

 its being the same, did we not possess a specimen from Chamisso, which is consequently the same as that 

 described by Lessing in the Linna?a, named as above, and identical with our own. Mr. Cruckshauks, Mr. 

 Macrae, Mr. Bridges, and Dr. Gillies have also gathered it at Valparaiso. 



6. BARNADESIA. Linn. 



1. B.I ulicina; foliis subulatis rigidissimis pungentibus, spinis nullis, involucri foliohs 

 subulatis rigidis scariosis (flavis), exterioribus recurvis ciliatis interioribus erectis extus 

 sericeis, pappo plumoso. 



Hab. Coquimbo.— The only specimen we have ever seen is too imperfect for us even to ascertain the 

 genus with any certainty. The habit is very remarkable. The plant shrubby, with glossy, yet slightly tomentose 

 branches; leaves numerous, about three-fourths of an inch long, shining, with an obscure nerve at the back, 

 grooved within, very rigid, and tipped with a yellow pungent point, bearing always m their axils a cluster 

 of young leaves, which are slightly downy. The receptacle is dotted and naked, and the general aspect ot 

 the flower not unlike that of Carlina vulgaris. 



7. TRIPTILION. Ruiz §• Pav. DC. 



1. T. spinosum; herbaceum, foliis radicalibus pinnatifidis, caulinis sessilibus inciso- 

 dentatis spinosis, caule superne paniculato-corymboso. Spr. — Ruiz et Pav. 



Hab. Valparaiso.

1. E. retiadatum; fruticosum, ramis angulatis, foliis oblongo-ovat.s subattenuatis 

 petiolatis crenato-dentatis subcoriaceis subtus reticulatis junionbus pnecpue viscose, 

 panicula corymboso-capitata, involucri sub-13-flori foliolis serie duphci glanduloso-pilosis. 



Hab. Valparaiso.-This seems to approach very near to E. viscosum, Kunth, but that is described with 

 a diffuse panicle, while in our plant the flowers are in a compact head.
