20. Dicranum (Campylopus pilifer) subcuspidalum Hpe., n. sp. 
Laxe cæspitosum, elatum, triunciale, stramineo-lutescens, 
splendens. Caulis crassus, adscendente ramosus ubique, usque 
ad comam interrupte fusco-tomentosus, apice penicillato-cuspi- 
datus, laxe foliatus. Folia firma, rigide patentia, in ramulis 
flagellaribus attenuatis, accumbentia, in coma paulo longiora, pe- 
nicillato-conniventia, e basi anguste cordata, latere rotundata, 
fuscata, late lanceolata, planiuscula, apice involuto-subulata, mar- 
gine infero anguste hyaline limbata, superne serrulato-denticulata, 
nervo basi latissimo latera folii ( 3 /s) superante, e cellulis rectan- 
gulis formato, versus apicem folii cellulis elongatis, subulam totam 
occupante percursa, apice hyalino parce dentato cuspidata, cel¬ 
lulis alaribus quadratis, maxime orbatis, interstitiis fuscis re- 
ceplis, in lamina lutescente, isolatis, inferioribus ovalibus majo- 
ribus, sensim versus apicem folii angustatis, minoribus, ellipticis, 
supremis minutissimis aggregatis. Cætera desunt. 
In vicinia Rio de Janeiro (Glaziou). 
Species peculiaris, ex habitu D. penicillaii , vero D. cuspidato 
affinis, sed caule interrupte tomentoso, laxe foliato, lutescente, 
splendente, foliis paterilibus, nervo laxiore, triplo latiore omnino 
diversa.

caulina inferiora laxius imbricata, superiora magis adpressa, hu- 
mida erecto patula, brevia, anguste ovato-lanceolata, apice pilo 
stricto dentata, hyaline cuspidata, concava, sicca convoluta, sub-
