    53*. Trichomanes venosum, 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. Beckeri, Krause; Philippi, in Linnaea, XXXIII. 305. Chili. Habit of HymenophyUum dichotomum. 03*. T. Luersseni, F. M.; Luerss., in Bot. Centralblatt, 1882, 440. Mountains of Aneiteum, G. Braithwaiie. 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. apiifolmm, Presl. HymenophyUum? puellum, Cesati, Fil. Polyn. Becc. 6, collected by Beccari on the mountains of New Guinea, is probably a form of this species. POLYP ODIACEAE. 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. Acrostichum, PoJypodiuvi)\ (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, Lindsaya); and (4) Indusium truly dorsal (e. g. Aspidiwn, Asplejiium). 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. Hancockii, Baker, n. sp. Stipes densely tufted, 1-1J in. long; paleae ovate or lanceolate, pale brown. Frond lanceolate, bipinnatifid, 2-3 in. long, ^ in. broad; rachis slender, strami- neous, naked ; pinnae deltoid, ^ in. long, cuneate at the base, toothed on the outer edge; lower lobes cuneate. Veins few,
