112 NEPHRODIUM § LASTREA. 



cially, including the involucres, are deeply tinged wirli almost a vermilion colour. 

 This specimen has a portion of the caudex attached, al)out 1^- inch long, which 

 would appear to be procumbent or scandent, stramineous, with numerous but 

 sparse subulate scales, mixed with needle-shaped bristles; this caudex, together 

 with the peculiarity of the texture and the obliquity of the involucres, induce me 

 to think it may prove to be a Davallia. — Perhaps no part of the world, at this 

 time, would yield a finer harvest of Ferns than Borneo.

 This is a large handsome Fern, with fronds of a delicate texture, 2-3 feet long 

 and pinnae 7-9 inches long and I inch broad, the segments long and narrow, ob- 

 tuse, with no very striking characters. 



92. N. (Lastrea) immersum, Hook. ; " caudex creeping, 

 stipes elongated, 3-4 feet long, frond coriaceous (?) glabrous 

 or finely pubescent with scattered glands beneath from a 

 broad base ovato-oblong or oblong acuminate pinnate, pinnte 

 8-10 inches long sessile articulated at the base (?) linear at- 

 tenuated at each extremity long acuminate at the apex 

 deeply pinnatifid, segments linear-oblong entire obtuse, sori 

 immersed arranged between the costule and the margin of the 

 segments, involucres reniform glabrous entire persistent."

 can be called "coriaceous;" there is a swelling around the base of the pinnae, 

 but scarcely an articulation. The species is closely allied to A^. ligulatum.
