frequent fluctuations of temperature, the annual change of dress which

Lieut. R. Strachey had mentioned a remarkable phenomenon to Major 
Madden, that the seeds of the same species of plant ripen much earlier 
on the lofty passes of the Himalaya than at their base. 
M. Boureravun’s intended Excursions in SPAIN. 
M. Bourgeaud of Paris has distinguished himself as a Botanical 
Collector, lst, in the Canary Islands, 2ndly, in the Pyrenees, and 
3rdly, in Corsica and the French Mediterranean coast. Not only are 
his specimens well preserved, büt well selected, and liberally supplied 
to the subscribers. They have the further. advantages of being well 
named by able botanists, and offered upon reasonable terms. No 
wonder therefore if the demand for them is considerable, and if, of his 
last collections, the demand exceeded the supply. 
M. Bourgeaud has been advised during the present year, we believe 
by the Professors of the Jardin des Plantes at Paris, to prosecute his 
researches in Spain, suggesting either the environs of Malaga, in the 
extreme south, or of Madrid in the interior. Either of them we believe 
to be good localities, and well worthy of the exertions of so experienced 
a Collector, and we are much mistaken if there will not be found a 
disposition to encourage him by the botanists of this country as well 
as in France. 
' Pranta FENDLERIAN X. 
The nature of Mr. Fendler's collections from North Mexico (and 
which have now been transmitted to the subscribers) is noticed at 
p. 44 of our London Journal of Botany. The specimens have all 
the beauty and perfection of those of M. Bourgeaud, with the addi- 
tional merit of eoming from a most interesting country. Dr. Asa 
Gray has, we have reason to know, prepared a named catalogue of 
this collection, which will be printed in the forthcoming volume 
(vol. iv.) of the Memoirs of the American Academy, and which, we 
believe, will also be delivered to the subscribers gratis. 
We learn with much satisfaction that Mr. Fendler has it in contem- 
plation to spend a season in a very interesting and unexplored country ;
