Mt Arnott's Tour to the Pyrenees. 2>T 



informed me, that the true L, heterophyUus^ as it is cultivated, 

 is a very different plant. I have long ago ascertained our plant 

 to be L. cirrhostiSy Ser. (gathered by Ph. Thomas in the ndgh- 

 bourhood of Olette), by means of an original specimen ; but in 

 order to avoid any mistake in others who may detect again this 

 species, I must remark, that, by a singular confusion, this is 

 placed in a section of Lathyrus, not only by Seringe, in De 

 Candolle's " Prodromus,'' but by Duby, in the " Botanicon 

 Gallicum,*" with which it does not agree. The character, as 

 given, is to have the petiols many- (5 or 6-) leaved, and the pe- 

 duncles many-flowered, while it is put into the section **' Annuiy 

 pedunctdis IS^/loriSfJbliis 2-3 jv^is^ The root, however, is 

 really perennial, and it belongs to the section " Perennes, pe- 

 dunculis muUifloris, Jbliis mvltijugis^ and it must be arranged 

 next to L. Iieterophyllus. I may add, that the other species of 

 this last section seem to be ill understood ; for my part, all the 

 specimens that I have seen of L. venosus, myrtifolius (with which 

 Torrey says L. stipulaceus Le Comte, is identical), polymor- 

 phus and pisi/brmis^ appear to me states of Pisum maritimum. 

 Our expedition to the summit of Mont Cady, on the 6th, was 

 also, on the whole, a prosperous one. This mountain consists of 

 three separate ridges. To the first is a very long, but not very 

 steep ascent ; and unless Lavandula pyrenaica^ which was every- 

 where, Siderites hirsuta, Vicia anobrychoides, and one or two 

 specimens of Trifolium lagopus, we scarcely saw any plant of 

 interest. The second ascent is much more steep, particularly 

 as, instead of following the easiest, or mule road, up to the ridge, 

 we took the shortest, and mounted through a wood as straight 

 as a narrow footpath among the trees permitted us. Here the 

 plants we observed of note were Teucrium pyrenaicuni and 

 Hypnum ru^idosum, Web. and Mohr, which last was very com- 

 mon all the way from Seo. Towards the base of the third 

 ridge, however, we found every thing more interesting : here 

 were Onopordon pyrenaicum, Scutellaria alpina, and Ononis 

 cenisia. On our ascent to the high peaks, we examined the 

 rocks on our right, and found Ramondia pyrenaica *, and Va-
