194 NEW MUSCI 
Stems loosely cæspitose, whitish, with dark purplish-brown 
radicles. Shoots of a lively green, scarcely exceeding three lines 
im length. In a dry state the white nerves are conspicuous on the 
ineurved backs of the leaves.  Perigonial and perichætial leaves 
cellulose but not papillose, whiter than the cauline. Perichetia 
curving up from the under side of the stem, the exterior leaves 
very minute, the upper and inner lanceolato-subulate, and with a — 
percurrent nerve, all closely adpressed and erect; the perichætia 
have their own radicles. Seta very slender, about half an inch 
long, curved at the top. Calyptra subulate, entire at the base. 
Inner peristome with sixteen subulate Jucinia. Allied to its 
congener from the Andes, H. radiculosa, Hook., differing (if we 
may judge by the figure given in Muse. Exot. t. 51,)by its far 
minuter size, the longer hyaline nerves of the leaves, the more 
pinnate habit of its stems, the more distant leaves, the longer 
operculum, and the scabrous pedicels.

1. H. clinocarpum, Tayl. Caule procumbente, implexo, vage 
ramoso, ramis brevibus, subcomplanatis ; foliis laxis, patentibus, 
concavis, estriatis, late ovatis, acuminatis, dentatis, ultra medium 
uninerviis ; setis scabris apice decurvis; capsula ovato-oblonga, 
inzequali, inclinata. 
On Pichincha. Prof. W. Jameson. Dec., 1846. 
Stems one to two inches long; shoots rather compressed. Pe- 
dicels about one inch high, roundly curved down at their tops. 
Inner peristome divided into sixteen split /acinia, with three very — 
short filiform processes interposed between each pair. Calyptra 
dimidiate. This may be compared with H. rutabulum, L.; but — 
the leaves are more distant, more patent, and destitute of s/rie; 
while the capsule is cernuous from the curving down of the pedi- 
cel. No male flowers observed. 
2. H. Conostomum, Tayl. Caule decumbente ; surculis erectis, ra- — 
mosis, erectiusculis, subcomplanatis ; folis arcte imbricatis, — 
erectiusculis, concavis, ex cordato-ovata basi longe tenuiterque | 
acuminatis, serrulatis, margine reflexis, substriatis, ruptinervibus; 
capsula cylindrica, leniter incurva; operculo conico; seta levi.
