1 96 Baker . — A Summary of the new Ferns 
53 *. Trichomanes veil o sum, R. Br. I cannot separate T. venus- 
tulum, Colenso, in Trans. New Zeal. Instit. XII, 366. 
54 . T. crispum, L. I can only separate as a variety T. digitatum, 
Sodiro, Recens. 4, non Swartz. It differs from the type by 
having the •indusium protruded entirely from the lamina. 
61 *. T. Hosei, Baker, in Journ. Linn. Soc. XXII. 223, tab. 12. 
Sarawak, Borneo, Bishop Hose. 
61 *. T. Beekeri, Krause; Philippi, in Linnaea, XXXIII. 305. 
Chili. Habit of Hymenophyllum dichotomum. 
63 *. T. Luersseni, F. M. ; Luerss., in Bot. Centralblatt, 1882, 440. 
Mountains of Aneiteum, G. Braithwaite. 
70 . T. rigidum, Sw. Surg. Halcro Johnston sends specimens con- 
necting with this species T. Hartii , Baker, in Gard. Chron. 1882, 
II. 680, collected at Sierra Leone by the late Dr. W. Hart. 
71 . T. apiifolium, Presl. Hymenophyllum? puellum, Cesati, 
Fil. Polyn. Becc. 6, collected by Beccari on the mountains of 
New Guinea, is probably a form of this species. 
POLYPODIACEAE. 
I should like to separate Hymenophyllaceae from Polypodiaceae as 
a distinct sub-order, and divide the latter into four tribes as follows : 
viz. (1) Indusium none (e. g. Acrosiichum, Polypodiuni) ; (2) Indusium 
formed only from the altered margin of the frond (e. g. Adiantum , 
Pteris) ; (3) Indusium formed in part from the altered margin of the 
frond, with an inner valve in addition (e. g. Dicksonia, Lmdsaya) ; 
and (4) Indusium truly dorsal (e. g. Aspidium, Asplenium). 
Genus 11. Woodsia R.Br. 
4 . W. lanosa, Hook., must be omitted. It is identical with Gymno- 
gramme Andersoni , Beddome, Fil. Brit. Ind. tab. 100. 
6. W. insularis, Hance, must also be omitted. It is made up of a 
mixture of W. ilvensis and manchuriensis , as is shown by the 
type specimens, now at the British Museum. 
6*. W. Haneockii, Baker, n. sp. Stipes densely tufted, 1-1 J in. 
long ; paleae ovate or lanceolate, pale brown. Frond lanceolate, 
bipinnatifid, 2-3 in. long, \ in. broad ; rachis slender, strami- 
neous, naked ; pinnae deltoid, J in. long, cuneate at the base, 
toothed on the outer edge ; lower lobes cuneate. Veins few,
