HYPNUM LARICINUM.
Hypnum stipu'atiim, caule erecto inferne denudato,
apice pinnatim ramoso, foliis bifariis verticalibus oblique
erectis submarginatis denticulatis, basi uninervi-
bns, stipulis cordatis breviter acuminatis serratis, nervo
perbrevi, capsula ovata nutante, operculo rostro curvato.
(Tab. XXXV.)
H a b . Ad promontorium Bonæ Spei. D. M e n z ie s,\7 ii\. In ju gis
Andiuin regione temper.ata. Huniboldl et Bonpland.
Radix repens, dense tomentosa. Caulis 2-3-uncialis, erectus,
inferne ramis destitutus, superne pinnatim divisus, ramis patentibus
vel etiam deflexis, plerumque simpiicibus. Folia intense
viridia, bifariam inserta, disticha, patentia, verticalia, oblique
late ovata, acuta, subundulata, mollia, indistincte marginata,
denticulata, nervo satis distincto prope medium evanescente
instructa. Stìpulce foliis düplo minores, cordatæ, breviter
acuminatæ, serrulatæ, nervo perbrevi. Perichcetialia
ovata, firistato-acuminata, nervo brevi. Selce numerosæ, non
raro aggregatæ, subunciam longæ. Capsula ovata, nutans,
punetulata. Operculum rostratum, rostro curvato. Calyptra
dimidiata. Peristomii dentes ext. angusti, flavi.
This approaches very near to the Leskea fiJicnlceformis, the
L.rotulata, and Leskea {Hypn., Sclivvacgr.) iamariscinaofW&A-
vvig. From the first it differs in its much smaller size but larger
leaves, and in its branches being never legularlv twice pinnated;
—from the second, in the stipules, which want the excurrent
nerve ;— and from the last, iu the absence of the setce among
the leaves. With regard to the Hedwigian L . tumariscina, indeed,
it does not accord either with Swartz’s deseiiption, or
with the specimen which he has kindly sent to me; and Swartz
is the original authority. His plant is destitute of setae, and I
do not find that it differs essentially from L . rolulata of Hedwig,
which ought thus to bear the n.ame of tamarlscina. I shall have
the opportunity of saying more of these species hereafter.
f l . laricinum is fouiKras well
the continent of Africa as
America.
