HOOKERIA RADICULOSA.
Hookeria caule repente vage ramoso, ramis compressis
subtus denudatis, supra foliosis, foliis ovatis subacuminatis
integerrimis, nervo ultra medium evanescente,
capsula ovata cernua, operculo rostrato curvato, calyptra
basi integra. ( T a b . LI.)
H a b . Crepidines juxta Caripe, locis scopulosis, temperatis, irri-
guis, altitudine 480 hexapod. Humholdt et Bonpland.
Caules repentes, ramosi, subtus foliis destituti, fibris numerosis
fuscis radicantibus obsiti, lateribus facloque superne foliosi.
Folia siibcoinpressa, parum concava, ovata, subaciiminata, nitida,
flavo-viridia, omnino integerrima, nervo ultra medium
evanescente instructa. Suhstaniia compacta, minute punctata.
Perichcetialia magis acuminata, nervosa. Seta subunciam
longa, flexuosa. Capsula ovata, cernua. Calyptra
subulata, integra. Operculum conico-rostratum, flavum, rostro
decurvo. Peristomium, ut in Leskea, flavescens.
Among the Humboldtian mosses a considerable portion belongs
to the genus Hookeria, or such plants as have all the characters
of a Hypnum or a Leskea, except the dimidiate calyptra.
The present species differs from most of the family in having a
single nerve to the leaf, and the under side of the stem destitute
of leaves, as in Anictangium torquatum.
