NEW MUSCI FROM THE ANDES. 187 
L4 
On some new Musor, collected by Proressor W. JAMESON on 
Pichincha. By the late Tuomas Taytor, M.D. 
Professor Jameson continues to transmit to Europe his dis- 
coveries in the Quitenian Andes. A tropical sun cannot exhaust 
his zeal, or enervate his exertions; and his success is measured 
not more by the multitude than the distinctness of the species he 
has collected. It will readily be perceived that the following species 
yield not in interest to any of those formerly described. The 
entire must form an important element in ascertaining, at a future 
period, the just relations of muscological life. 
Puascum, L. 
1. P. Jamesoni, Tayl. Hermaphroditum. Caule subsimplici, erecto; 
foliis congestis, rigidis, erectiusculis, summis subpatentibus, ex 
oblonga amplexante basi subulato-setaceis, margine planis, ser- 
rulatis; setis subflexuosis, exsertis; capsula erecta, spheerica, 
apice obtuse apiculata, siccitate corrugata. 
On Pichincha. Prof. W. Jameson. May, 1847. 
Plants loosely aggregate, 2—3 lines high, dark olive green. 
Shoots attenuated below, bushy above. Leaves half as long as 
the shoots, their nerve percurrent, their points sometimes colour- 
less and transparent. Fruit terminal, but by the prolongation of 
the new shoot at length appearing lateral. Flowers hermaphrodite ; - 
anthers oblong, pellucid, pistilla opaque; paraphyses numerous. 
Capsule round, yet slightly produced at the base, as well as at the 
apex, the sides very thin, wrinkled when dry. Pedicel 2-3 times 
as long as the capsule. Seeds rather large, dark reddish-brown, 
their coats pellucid. The habit of a Bartramia, the rigid leaves, 
the great diameter of the capsule, and the hermaphrodite flowers, 
render this species remarkable in the genus. 
Tortura, Hedw. 
1. T. campylocarpa, Tayl. Caule laxe cæspitoso, subramoso ; 
foliis laxe imbricatis, patenti-recurvis, ex lata ovata basi lineari-
