GYMNOSTOMUM GRACILE.
Gymnostonnmi caule casspitoso subramoso foliis ovato-
lanceolatls integerrimis nervosis longe piliferis, capsula
oblongo-cylindracea pendula, operculo hemisphse-
rico, mutico. ( T a b . XXII.)
Leptostomum gracile. Brow nin Limi. Traìis. v. 10.
p . 321.
H a b . In sinu Dusky Bay dicto, in Nova Zeelandia. D. Menzies,
1791.
Caules semiunciales, simplices vcl divisi, inferne radicibus tomentosis
fuscis obsiti. Folia erecto-patentia, ovato-lanceolata,
integerrima, inferiora acuminata, superiora obtusiuscula, omnia
nervo in pilum longum ultra apicem producto instructa.
Seta biuncialis, gracilis, flexuosa. Capsula oblongo-cylindracea,
pendula, ore intus membrana annulari alba. Operculum
hemisphaericum, pbtusum.
I have stated my reasons for not adopting the genus Leptostomum
under Gymnostomum Menziesii (T a b . VI.), a species
near to which tliis ought certainly to rank, although it differs
abundantly in the shape and direction of the capsule and the entire
leaves. In this plant, too, the hair-like points of the leaves
are much longer.
