138 Mr Arnott's T(yiir to the South of' France 



net and Villefranche we found Quercus tauzin, Hypeccmm gran- 

 diflorum, Benth. and Myosotis lappula^ and about Villefranche 

 Galium maritimum ! Bupleurum fruticosum, Cnidium pyrence- 

 um, Spr. and Galium Iceve. 



At Prades we made acquaintance with M. Coder, a zealous 

 botanist, who, during our stay at this place, procured us every 

 possible facility for the excursions and researches we had to 

 make. Like M. Xatard of Prats de Mollo, he opened to us his 

 collection of plants, particularly of the department we were in, 

 and shewed us also several specimens that had served M. De 

 Lapeyrouse wherewith to make several of his species. He ac- 

 companied us also in a part of our excursions, and got us ex- 

 cellent guides for the others. The most important we made 

 were to the Trancade d'Ambouilla and the Font de Comps. 

 The former is close to Villefranche, and, with the assistance of 

 M. Coder, we procured a few good plants, though the greater 

 part had long since done flowering : — Salsola prostrata^ Buffo- 

 nia perennisy Galium glaucumy Lysimachia ephemerum^ Ge- 

 nista hispanica^ Antirrhinum latifolium, all occurred here. 

 Bupleurum petiolare. Lap. a mere variety of B. jfalcatum, was 

 also met with. One specimen was got in an advanced state of 

 Orobu^s Jiliformis *, Lam. and a few of Alyssum halimifolium. 

 This plant, though De CandoUe quotes this exact locality for his 

 A. macrocarpum^ is nevertheless the true A. halimifolium, Linn, 

 at least it accords precisely with what is found under that name 

 in the maritime Alps ; but A. pyrenaicum. Lap. is, on the other 

 hand, a variety, if not identical with the true A, macrocarpum 

 from the Cevennes, as De Candolle properly judged in the Sup- 

 plement to the " Flore Fran^aise," but which, by some mistake, 

 he has kept up as a good species in his " Systema. •[•" 



• Mr Bentham refers this to O. albus, but Seringe in DC. Prod, to O. ca^ 

 nescens. My specimen is too far gone for me to determine to which it belongs. 

 I may state here, that, in the three first varieties of O. canescens of Ser. the 

 alae of the corollae are in part soldered to the carina, which is not the case with 

 O. aJbus. The style in his var. y is nearly linear ; but in his var. /3, it is ex- 

 tremely broad towards the apex. Perhaps this last is a distinct species, and 

 to be referred to Lathyrus. 



+ At the Trancade d'Ambouilla, we also met with Hippocrepis comosa. 

 I merely mention the circumstance here, in order to state what Mr Ben- 

 tham and I only a?»certained lately, that Hippocrepis scorpioides, Req. in Benth. 

 Cat. and in the former part of this journal, is identjical with //. glauca^ Ten.
