HEDWIGIA SCHMIDTII. 
Hedwigia caule procumbente ramoso, foliis undique im- 
bricatis erectis ovato-acuminatis striatis integerrimis 
enervibus, capsula globosa, operculo subulato. (Tas. 
CES=.) 
Has. In sylvis umbrosis prope Laguna truncos et ramos arbus- 
torum vestiens. Teneriffe. D. Prof. Schmidt, 1815. 
Caules digitales et ultra, procumbentes, flexuosi, vage ramosi, 
ramis attenuatis. Folia undique imbricata intense atro-viridia, 
superiora pallidiora, omnia dense imbricata, erecta, ovato- 
acuminata, integerrima, enervia, longitudinaliter striata, mar- 
ginibus reflexis. Perichetialia insigniter convoluta, exteriora 
minora, late ovata, subacuminata ; interiora prelonga, magis 
acuminata. Seta lateralis, sesquiunciam longa, flexuosa, rufo- 
fusca. Capsula exacte spherica, erecta, ore contracto, in- 
tus membrana annulari alba. Operculum longirostrum, cur- 
vatum. 
The annular membrane within the mouth of the capsule of this — 
moss was noticed by its lamented discoverer Dr.Christian Schmidt, 
and it is very obvious in all the specimens which | possess. ‘“ In- 
ter 1000 specimina (he further remarks) unicum modo calyptra- 
tum et operculatum detegere potui ;” but that calyptra, repre- 
sented on the left hand specimen, is in too young a state to al- 
low of my determining the exact figure of it. In habit this moss 
accords very satisfactorily both with Hedwigia Humboldtii and 
H. secunda, though it is still nearer perhaps to Leucodon sciu- 
roides.
