22 Ferns of British India and Ceylon. 



The character of this variety is a very short, triangular frond 

 on a very long stipe ; it is, however, only an extreme form of deltoid 

 farinosa; some of my fronds are 14-15 inches long including 

 the stipe, the frondiferous apex being only 3 inches ; the 

 shorter stiped fronds are, however, all fertile in my examples, and 

 of the same triangular form ; it approaches C. argentea, but the 

 frond is much more cut. 



Cheilanthes farinosa var. albo-marginata. (=Cheilanthes 

 albo-marginata, No. 10 of Handbook.) Typical specimens of this 

 fern differ from Dalhousise in the scales having translucent 

 margins, in the presence of farina, and in the involucre being 

 much lacerate ; it is so closely allied to Dalhousiae that I now place 

 it also as a variety of farinosa ; the character of the scales is not 

 constant. 



9A. Cheilanthes Delavayi. {Baker.) Caudex erect ; stipes 

 tufted, hairy, castaneous, 5-6 inches long ; frond deltoid or 

 oblong-deltoid, tripinnatilid, 6 inches long, 2-3 inches broad 

 herbaceous, green on both surfaces, a little pubescent ; lower 

 pinnae the largest deltoia-petioled ; secondary pinnae deltoid, ^-f 

 inches broad, cut down nearly to the rachis into contiguous 

 oblong segments ; veins clearly visible, pinnate in the segments, 

 the veinlets forked ; indusium continuous, pale coloured crenate 

 persistent. Baker, Ann. Bot. v. 1891. 



Yunan, Shwang Sheteon, above Tapintze, near Tali. 

 {Delavay.) Very near some of the less cut forms of subvillosa, 

 and probably only a deltoid form of that species. 



12. Cheilanthes argentea. The Birmese locality is the 

 Zwakabin Mountain, where it was collected by Mr. Parish at 

 1800 feet alt, 



Pellsea tamburii {Hook.), Handbook, p. 101, is a synonym 

 here. 



2. Onychium japonicum. The root stock is generally creeping.
