rather, as Fries has stated, to 0. globularis or its allies. C. pedata 

 is undoubtedly a fictitious plant, and the name, as used by Linnaeus, 

 cannot be pressed into service. It is interesting in this connection, 

 however, to find in the herbarium prepared to represent the Hortus 

 Cliffortianus, which is deposited at South Kensington, a specimen 

 of C. ornithopoda which is labelled C. pedata. How much importance 

 can be attached to this specimen is uncertain, as it is not known 

 whether this herbarium passed through Linnseus's hands. 



The curious herbarium of Thomas Walter, author of ' Flora 

 Caroliniana ' (1788) is also at South Kensington, but its collection 

 of Carex is confined to a single unnamed scrap of Carex riparia Curt. 



ON A THIRD COLLECTION OF FEENS MADE IN WEST 



BORNEO BY THE BISHOP OF SINGAPORE AND 

 SARAWAK. 



By J. G. Baker, F.R.S. 



The present collection is a continuation of two previous ones, 

 reported upon in the 'Journal of the Linnean Society,* vols, xxii., 

 p. 222, and xxiv., p. 256. West Borneo is evidently very rich in 

 ferns, and no doubt a large number of new species still remain to 

 be discovered. The numbers are Dr. Hose's collecting numbers, 

 and those within brackets indicate the position of the new species. 



217. Dicksonia sorbifolia Smith (D. papnana F. M.).— Miri, 

 Sarawak, Chas. Hose. A very rare species, known only in New 

 Guinea, besides C. Smith's and Roxburgh's original localities. 



218. Trichomanes rigidum Sw. — Matang, Sarawak. 



219 (17*). Davallia (Leucostegia) Hosei, n. sp. — Rootstock 

 creeping, £ in. diam., clothed with minute adpressed linear brown 

 palese. Stipes naked, brownish, 12-16 in. long. Lamina oblong- 

 lanceolate, bipinnate, firm in texture, green and glabrous on both 

 surfaces, l|-2 ft. long, 5-6 in. broad. Pinn® distant, lanceolate, 

 ascending, subsessile, f-1 in. broad, cut down to the rachis into 

 unequal-sided oblong-lanceolate deeply crenate pinnules £ in. broad, 

 produced on the upper and cut away on the lower side at the base. 

 Veins indistinct, one to each final lobe. Sori small, one at the base 

 of each final lobe. Indusium as broad as long, rigid, glabrous, 

 persistent, free at the sides. — Lambur, Sarawak, Gluts. Hose. Allied 



to 1). Khit/ii, nephrodioides, and ciliata. 



220 (18*). D. (Leucostegia) oligophlebia, n. sp. — Rootstock 

 slender, creeping, clothed with minute adpressed 

 palese. Stipe slender, naked, under an inch long, minutely scaly 

 towards the brown base. Lamina lanceolate, rigid, pinnate, green 

 and glabrous on both sides, l£-2 in. long, £ in. broad. Pinnae 

 sessile, rhomboid, obtuse, 3-lobed, with only one vein to each lobe. 

 Sori usually only one to a pinna, placed in the small anterior lobe. 

 Indusium suborbicular, rigid, glabrous, free at the sides. — Laupi,
