Has. Borneo, near Sarawak, Mr. Thos. Lobb. 
My only specimen of this Ophioglossum is that here re- 
presented, where three fronds arise from one small but some- i 
what tuberous root, and the plant seems to be terrestrial and ? 
to grow erect. Were it an epiphyte and a pendent frond, the j 
species might be supposed to be a form of the O. pendulum : 
(see Hook. et Grey. Ic. Fil. Tab. 19); but here is no disposition 
in the frond to be dichotomous; and the narrow stipes of 
our present plant, the elongated peduncle and the situation 
of the peduncle (itself as long as the spike) forbid such a 
supposition. The membranaceous texture is in favour of its 
being the same as OQ. pendulum; and it may be considered to 
hold an intermediate rank, between the terrestrial erect and 
the epiphytal pendent species.
