sixteen trabeculate pale teeth, each marked at the base with a 
longitudinal opaque line, ¿nner of sixteen pale setaceous Jacinia, 
united at the base by the inner membrane of the capsule. The 
habit is of Pterogonium filiforme, Hedw., but the peristome is dif- 
ferent ; besides, the leaves are strongly nerved, and with longer 
apiculi.

On Pichincha, 1827. Prof. W. Jameson. Dr. Greville’s Herb. 
Stems eight to twelve inches long, the younger branches pale 
yellowish-green. Leaves distichous; in a third row beneath the 
stem, they are fewer and at unequal distances ; the inferior margin 
at the base is incurved; their summits have an exceedingly short — 
apiculus, beneath which is a considerable cavity. Calyptra dimi- 
diate. Inner peristome very slender, and sometimes very short, 
connected at the base by a very shallow membrane. This has the 
habit of Neckera disticha, Sw. Fl. Ind. Occid., which we have 
from the late Mr. Dickson. Swartz’s plant is much smaller, has 
leaves more obtuse, and destitute of any apiculus, besides, they 
are furnished with a distinct though short nerve, and the capsule 
is not concealed within the perichetium. No male flowers were 
observed. |
