subrigid, green, glabrous, \ ft. long, i-ij in. broad at the 

 middle, narrowed gradually to the base. Pinnae sessile, un- 

 equal-sided, laciniate-pinnatifid. Veins indistinct, erecto- 

 patent. Sori finally forming a continuous mass, covering the 

 whole pinna, except the tip and outer edge. China ; Chefoo, 

 Hancock, 14. 



106*. A. formosanum, Baker; A. Hancockit, Baker, in Journ. Bot. 

 1885, 104, non Maxim. Formosa, Hancock, 134. Allied to 

 A. laciniatum and the small forms of A. affine. 



107*. A. subacjuatile, Cesati, Fil. Born. Beccar. 20, tab. 3, fig. 5. 

 Borneo, first gathered by Beccari, later by Curtis and Bishop 

 Hose. 



114*. A. Lydgatei, Hilleb. Fl. Hawaii, 596. Sandwich Islands. 

 " Allied to A. difforme, R. Br." Not seen. 



119. A. pekinense, Hance. Further material shows that 132, 

 A. Saulii, Hook., in Blakistone's Yangtsze, 303 (1862), is a 

 larger, more compound form of the same species, and the 

 latter is the older name. It has lately been found by Levinge 

 in the Himalayas (Chumba and Jhelum Valley). 



124*. A. sphenotomum, Hilleb. Fl. Hawaii, 529. Sandwich Islands. 

 Not seen. 



125. A. furcatum, Thunb. An earlier name for this cosmopolitan 



species is A. praemorsum, Swartz, Prodr. Fl. Ind. Occ. 130 

 (1788). 



126. A. affine, Swartz. In Madagascar this proves to be excessively 

 variable in cutting. I now refer here A. simillimum, Kuhn, 

 in Hildeb. PI. Madag. Exsic. No. 3773 ; A. Gilpinae, Baker, 

 in Journ. Linn. Soc. XVI, 200 ; A. herpetopteris, Baker, in 

 Journ. Linn. Soc. XVI, 20 ; and A. viviparoid.es, Kuhn, in 

 Hildeb. PI. Madag. Exsic. No. 4148. See also vars. Pecten 

 and tanalense, Baker. 



133. A. fontanum, Bernh. I place as a variety very near exiguum, 

 A. yunnanense, Franchet, in Bull. Bot. Soc. France, XXXII, 

 28, gathered in Yunnan by Father Delavay. 



133*. A. chihuahuense, Baker, n. sp. Stipes densely tufted, casta- 

 neous, green upwards, |-i in. long. Frond oblong-deltoid, 

 bipinnate, moderately firm, glabrous, an inch long. Lower 

 pinnae the largest, sessile, ovate, lobed down to the base on 

 the upper side (lobe obovate-cuneate), cuneate-truncate on the
