NEW BRITISH MOSSES. 181 
siecitate erecto-patulis, anguste-ovatis, acuminatis, enervi- 
bus, sparsim denticulatis, perichætialibus spinuloso-ser- 
ratis; seta levi; capsula parva, ovali, suberecta ; operculo 
conico, obtuso. 
Hypnum confervoides Drummond's Musci Americani, No. 
190; (nec Bridel). 
Has. Growing intermixed with Jungermannia trichophylla on 
basaltic rocks in a shaded situation by the Tees’ side below 
Winch Bridge. I observed only a single patch, destitute 
of capsules, but possessing perichetia. 
Guided by the authority of Drummond’s Musci Americani, 
I published this moss in my “ Musci and Hepaticæ of Tees- 
dale” as Hypnum confervoides, Brid., not, however, without 
adding a mark of doubt, for I perceived that it differed in 
Some points from the character given by Schwaegrichen. I 
have since received from Dr. Montagne and Mr. Borrer (ex 
Schimper) specimens of the £rue H. confervoides, which 
enable me to decide that my moss is a very distinct (though 
allied) species. M. Bruch, in the London Journal of Botany, 
has referred Drummond’s moss to Leskea subtilis, Hedw., 
and a similar opinion was formerly entertained by Dr. Taylor ; 
but both these distinguished Cryptogamists now declare 
themselves convinced of its being a new and undescribed 
Species. The former has observed to me, “entre Hypn. con- 
Servoides, Leskea subtilis et votre Leskea il y a une telle affi- 
nité dans le habitus, la forme et le tissu réticulaire des feuilles 
et dans l'inflorescence, qu'elles doivent étre placées dans une 
disposition naturelle à la méme section. C'est pourquoi je 
Proposerais, pour éviter de l'erreur, de changer le nom et de 
donner à cette belle espèce celui de Leskea Sprucii.” I am 
happy to add also the testimony of two such able botanists as 
T. Wilson and Dr. Montagne, who have from the first main- 
tained the same opinion respecting this moss as myself. 
Leskea Sprucii differs from L, subtilis in being still smaller 
and more delicate ; the stems erect and very sparingly branched 
(but in L, subtilis procumbent and much branched); the
