urtica/blia. Medicago suffruticosa * occurred in the bed of 

 a torrent. But what principally delighted us, was Cardamine 

 lati/blia, and a new species of Santolina {^S. pect'mata, Benth. 

 Cat.). This is a remarkable species, closely allied to S\ cdpina 

 and S. ej'iosperjua, and agreeing witlv^eni in having the leaves 

 pinnatifid, but differing in being a shrub, and having the scales 

 of the involucruni nervose and slightly pubescent. 



Prats de Mollo is a very pretty small town, situated in an 

 agreeable and picturesque valley. 



With the exception of a short walk the evening of our arrival 

 along the banks of the river that passes the town, in which we 

 found Scropkular'ia Scopolii, Thalictrinn aquilegi/blium, Saooi- 

 Jraga rotundrfblia, Cardamine lati/blia, Lamium stoloni/erum, 

 Lap. (which is certainly the same with L. maculatum, Linn, and 

 L. hirsutiim, Lam.), and Bunium pyrenaicurn^ Lap. (Myrrhis 

 j)tjrenaicum, Spr. but not distinct even as a variety from the 

 common M. Bunium, Spr.), we made no excursion but to the 

 Tour de Mir, an old watch-tower on the summit of the hill to 

 the south of the town. As Prats de Mollo is about 500 toises 

 above the level of the sea, and the Tour de Mir is still more con- 

 siderably elevated, I should not suppose it to be at a less elevation 

 than 4000 feet, and of course we expected plants of a somewhat 

 different description than we had as yet encountered. On our 

 ascent, we deviated slightly from the road, to seek for the Se- 

 dum divaricatum^ Lap. auA^Orobanche pru'mosa. The former 

 was not yet in ffower ; but notwithstanding the long argument 

 held forth by Lapeyrouse in the Supplement to the " Histoire 

 abregee des Plantes des Pyrenees,'*' it was perfectly clear that 

 De Candolle was right in saying that it was identical with 

 S. saxatUe of other authors -f-. As to Orobanche pruinosa, this 

 locality was interesting, as being the only one in France, and 

 the only one known to Lapeyrouse when he described the spe- 

 cies. The plant had^ however, been imported along with beans 

 from Catalonia ; and it is not probable that the farmer here shall 



• The flowers of this are yellow, not blue, as Lape^'rouse says. Can his 

 Jlf. tornata be the same plant ? 



-f Such I state as my own opinion, after a careful comparison of numerout 

 specimens gathered principally in the Vallee d'Andorre, with the Swiss S. so*' 

 atile. My friend Mr Benthani, however, considers the two as rery distinct,
