SPLACHNUM SCABRISETUM. 
Splachnum foliis lingulatis obtusissimis, nervo afte apl- 
cem evanescente, capsula ¢ylindracea apophysi vix la- 
tiore, seta scabra. (Tas. XXXII.) 
Has. In umbrosis temperatis Gonzanamam inter et Luearque 
(Prov. Jaen de Bracamoros), altitudine 1060 hexapod. Hum- 
boldt et Bonpland. 
Caules cxspitosi, vix unciales, subsimplices, inferne dense radi+ 
culosi. Folia laxe imbricata, erecto-patentia, undulata, flac- 
cida, sordide viridia, lingulata, integerrima, apice obtusissima, 
reticulata, nervo fusco ante apicem evanescente instructa. 
Seta unciam longa, flexuosa, pallide rubra, tuberculosa. Cap- 
sula cylindracea, apophysi vix latior, fusco-viridis; demum, 
post semina ejiciantur, intense fusca, magis angusta, et una cum 
apopliysi longe cylindracea. Calyptra integra. Operculum 
obtuse conicum. Peristomium intra marginem oris, e denti- 
bus constans sedecim per paria approximatis, rubro-fusciss 
siccitate erectis vel recurvis, madore insigniter involutis fere ut 
in Tayloria splachnoide. 
S. scabrisetum in the leaves is not to be distinguished from 
Weissia splachnoides, and the whole plant bears a great affinity 
to Splachnum Freelichianum. In the subject of this plate, the 
roughness of the fruitstalk will afford a sufficient mark of discri- 
mination ; and a further character is to be found in the teeth of 
the peristome being situated within the mouth of the capsule, and 
so remarkably involute when moist, that the plant in this state 
might be easily taken for a Gymnostomum.
