246 Mr Arnotfs Tour to the South of' France 



his C. ericoides, but with which plant the phrase of Linnaeus has 

 no relation. This circumstance induced Dunal to doubt that 

 Willdenow was correct ; but it was not till after the publication 

 of De Candolle's Prodromus, that he discovered, by what he 

 considers an authentic specimen in M. Bou chefs herbarium, 

 that it belongs to his first section Halimium. It has exactly 

 the habit and appearance of Hel. libanotis, and only differs by 

 the peduncles being equal in length to the bracteae, while in 

 H. libanotis they are twice as long ; but these characters seem 

 too variable to constitute of it more than a mere variety." 



9^Qth April,- — " To-day, we made an excursion for a*couple of 

 hours not far from the house, hiter alia, we met with Orni- 



thopus scorpioides, Lathyrus (not agreeing well with the 



description of any in De Candolle's Flore Fran^aise or the Sup- 

 plement), Vicia narbonensis^ and some other rare species. It is 

 strange that Willdenow quotes England as a locality for Vicia 

 narbonensis ; I know not upon what authority. Smith and 

 the other English botanists who write on the Flora of Great 

 Britain, have prudently left it out, but take no notice of Will- 

 denow"'s assertion. I suspect that many other species allowed 

 in the British Flora, ought to be dismissed with as little cere- 

 mony. Thus, Euphorbia characias has surely no title to rank 

 as indigenous ; when found in France, it never gets beyond the 

 region of the olive trees. We to-day gathered and examined 

 a moss that Mr Bentham first observed a few weeks ago : it was 

 not in a very perfect state, ])ut I consider it a Didymodon 

 (D. Benthamii, nob.) at least it accords with that genus in its 

 peristome. Its habit is precisely that of a var. of Tortula cir- 

 rata f Trichostomutn barbula, Schw. but a decided Tortula), 

 that I have received from Rio Janeiro. On the rocks around 

 the source of the Lez are a few plants of Asplenium glandulo- 

 sum. 



*' As some of our plants have been very long of drying, par- 

 ticularly the germens of some Irides and Narcissi we gathered 

 at the Pont du Gard, we resolved this evening to make some 

 large packets of the whole we had at present in progress, and 

 put them into the large oven used for baking the out-of-doors 

 servants' bread."
