Mr. R. Spruce on the Musei and Hepatice of the Pyrenees. 93 
Leskea rostrata and attenuata, Physcomitrium, acuminatum, Tor- 
tula cespitosa, Dicranum fulvum, Fissidens grandifrons, &e. _ Tor- 
tula chloronotos reappears in the isle of Teneriffe. There are only 
the following species whose occurrence westward of the Pyrenees 
has not yet been recorded :— 
Hypnum Pyrenaicum. Tortula inclinata. 
Vaucheri. Encalypta ligulata. 
Isothecium Philippianum. Buxbaumia indusiata. 
Bryum polymorphum. Plagiochila Pyrenaica. 
Mnium medium. Scapania apiculata. 
Of the few mosses which grow on the southern slope of the 
Pyrenees, only one species (Tortula cespitosa) was not found at 
all on the northern. The Spanish Pyrenees have in fact a pecu- 
liarly arid aspect (to the eye of a cryptogamist), and correspond 
well with the distant view I have had of the dry and naked 
sierras of Spain*. 
If we now compare the three districts of the Pyrenees, above 
defined, one with another, we find a considerable number of 
species peculiar to each. The following mosses, gathered in the 
Western Pyrenees, were none of them observed in the Central 
and Eastern Pyrenees. [Those species marked with a (+) are 
peculiar to the sandy plains of the Landes. ]

* Cavanilles, in his ‘ Observaciones sobre la Historia Natural, &c. del 
Reyno de Valencia (Madrid, 1795),’ amongst all the localities which he so 
minutely describes, mentions but one of bryological promise, where he ob- 
served the solitary moss which enters into his catalogue of the plants. In 
speaking of the mountains of Valldigna (p. 218) he says, ‘‘ Los montes por 
donde estén expuestos al mediodia son secos, y que no hay fuentes en sus 
raices : al contrario las faldas septentrionales de todos ellos estan sembradas 
de sitios himedos y frondosos, y en las raices nacen fuentes abundantes. 
. . -- Enel valle de Barig son innumerables las fuentes que nacen desde 
Aldaya hasta Puigmola..... En estos sitios htimedos y sombrios esta 
siempre viva la naturaleza, cubierto el suelo de vegetales, y casi siembre de 
flores : alli se disputan las plantas el terreno. La doradilla (Ceterach), el 
polipodio comun, el pteris (Pé. aguilina) y la jungermania allanada (Jo. 
complanata) occupan las hendeduras de las pefias.”
