Hab. Island of St. Thomas, lat. 0, Mann. 
Pale glaucous green; stems two to three inches high, curved; leaves 
secund, at the apices of the stems faleate. A more robust species than 
L. macrodon, Hook.

D. oBLIQUATUM, sp. nov. Dioicum, ezspitosum, caule humili ramoso, 
foliis subsecundis e basi latiore sensim longe angustatis, nervo latitu- 
dinis folii partem tertiam occupante fere ad apicem a pagina distincto, 
apice dorso marginibusque serrulatis, cellulis alaribus a reliquis non 
discretis, basi oblongis rectangularibus, ad nervum majoribus et spa- 
tium fere quartum folii basis occupante, inde oblongis, ad apicem 
rotundatis, perichztialibus e basi latiore oblongo-ovata convoluta su-

recto inclinata cylindracea inzquali viridi siccitate plicata, operculo 
subulato longe rostrato rubro, peristomio dentibus elongatis dicranis. 
Hab. Peak Clarence, Fernando Po, on trees, Mann. 
The foliage of this species resembles that of D. fulvum, Hook. ; but the 
capsule is more like that of D. Scottianum, Turn., which is a much larger 
species. D. flagellare, Hedw., has leaves wider upwards, with a different 
structure at the base; in D. obliquatum the place of the alar cells is 
evident, but the brown enlarged cells appear to be dispersed through the 
base of the leaf in an irregular manner. The inclined capsule of this 
moss gives it a different appearance from any of its near allies. 
(Pedunculus flexuosus.)
