Ha b . In sinu Dnsky bay dicto apud Novain Zeelandiam.
D . Menzies, 1791.
Caulis repens, flexuosus, filiformis, ramosus, foliis plerumque de-
stitutus, ramis erectis iterum saepissime divisis. Folia fusco-
viridia, nitentia, undique inserta, falcato-secunda, ovata, concava,
longe acuminata, integerrima, vel sub lente apice minutissime
serrulata, omnino enervia. Seta subimciali.s, flavo-ru-
fescens. Capsula ovato-oblonga, cernua, fusca. Operculum
rostro longo tenui. Calyptra pallide fusco-flavescens, ditni-
diata. Peristamii externi dentes 16, intense flavi, transversim
striati, margine quasi denticulati ; interni membrana plicata,
16-fida, segmentis ciliis interpositis.
H. tenuirostre belongs to a numerous family of the genus remarkable
in having falcate leaves; and though the habit of this
plant is very unlike that of PI. cnpressiforme, yet the leaves, when
magnified, bear no inconsiderable resemblance to some of its
varieties, from all which it may be at once distinguished by the
length of the operculum.
