Gymmstomuin caule elongato subramoso, foliis ovato-
lanceolatis margine insigniter involutis, nervo ad apicem
attingente, seta elongata, capsula anguste cylm-
dracea,ore annulato, operculo subulato. (Tab.CLIV.)

Caules laxe cæspitosi, vix unciam longi, simplices vel .licbotome
divisi. Folia intense-viridia, sublaxe undique disposita, erecto-
patentia, siccitate crispa, ovato-lauceolata, subcannata, margine
insigniter involuta, integerrima, nervo valido concolore
ad apicem attingente sed non excurrente instructa. Perichcetialia
reliquis similia. , Se/acaule paulo longior, erecta,flava.
Capsula elongato-cylindracea, erecta. Os annulo elastico horizontali,
demum erecto et dissiliente, præditiiin. Calyptra dimidiata,
anguste subulata. Operculum subulatum, capsula
triplo brevius.
This has much the habit of a Toriula ; but the capsule is altogether
destitute of a peristome, though furnished wiih an annulus
exactly a s in G ym n o s io r n u r n juiaceum of this work. ( F a b .
XLH.)* On removing the operculum, a portion of the columella,
as it appears to be, always adheres to the inside of it, as
may be seen at fig. 9.
