the close affinity of this species with A. escidcnta f. iypica^) as 

 \vell as with A. Pyhu'l, A. memhranacea and A. f/randifolia J. Ag. 

 The roscmblanco of this species to A. cscuhnta Grey, is merely 

 superficial. Both are readily distinguished by the disposition of 

 sporophylls and by other characters. With A. PtjJaii Geey. and 

 A. memhranacea J. Ag., as far as I understand these species, A' 

 doUchorhachis Kjellm.' has nothing to do. 



A fully matured specimen of this species is not known to us 

 It can not, therefore, be ascertained whether the species belongs 

 to the Holosoria or to the Metasoria. The type specimen of A. 

 doUchorhachis is provided with sporophylls yet faintly soriferous 

 So also A. crispa Kjell:\[. The sori appear to dcYclop first in the 

 lovfcr halves of the sporophylls and then spread gradually upwards. 

 In the specimen (No. 2101) under A. muscefolia J. Ag. in the 

 Agardhian Herbarium, the sori begin to appear as an elliptical 

 patch at a point a little below the middle of the length of each 

 sporophyll. In both cases there is no sudden change of breadth 

 in the soriferous and non-soriferous part. These examples lead me 

 to assume, after considering the other species, that the present 

 species belongs to the Holosoria. 



Remarks on the synouyins. Unfortunately I failed to study the 

 type of A. elUptica in K.tellman's collection at Upsala. Its co- 

 type, collected at Pitlekay in July, 1840, was found in the 

 Agardhian Herbarium at Lund (specimen No. 2082). Its stipe 

 measures about 6 cm. in length, with numerous, long, cuneate 

 sporophylls closely pinnately disposed. The midrib is about 3 mm. 

 wide, imich narrowed at the transition region. The blade is un- 

 dulately plicated, acute at the base but abruptly broadened upwards.
