length partially or wholly recurved margin of the frond. Spores 

 roundish-tetrahedral. 



Frond not covered with white papillae beaueath. Sori extending 



some distance from margin . . . . . . .1. tenuifolia. 



Frond pure white with waxy papillae beneath. Sori only forming a 

 line round the margin 2. farinosa. 



1. C. tenuifolia, Siv. 



A small very pretty fern with shortly creeping scal}^ caudex ; stipes 

 more or less tufted deep brown or black, those of the fertile fronds 

 much longer than of the barren. Barren fronds mostly 3-4" deltoid, 

 2-3-pinnate, pale beneath but not white-mealy, nearly glabrous, 

 sparsely hairy above. Fertile fronds usually more elongate up to 

 12" or 18" long including the stipes, otherwise similar. Lowest one or 

 two pairs of pinnae longest, 2-4", with the lowest basiscopic secondary 

 pinnae often twice as long as the others and pointing backwards, 

 ultimate pinnules with small elliptic lobes • 1--2" long only, the larger 

 crenate. Rhachis mnged above. Sori submarginal on the crenatures, 

 ultimately confluent, margin of the lobes more or less recurved. 



On moist banks. Eanchi ! Hazaribagh, Gamble, Clarke ! Manbhum, CampA 

 Singbhum ! Frequent throughout Chota Nagpm-. Puri (Barkuda I.), C. & N. ; 

 Sambalpur, Griff. ! Fr. Sept.-Nov. Beddome calls it annual, but although it 

 appears to curl up and die in the hot season, I think it is usually perennial. 



2. C. farinosa, Kaulf. 



A very pretty small tufted fern wdth more or less elongated black 

 or chestnut glossy stipes, scaly when young. Frond (with the stipes 

 which is usually about the same length as the blade) 4-20" long, 

 smaller usually somewhat deltoid, larger usually lanceolar in outline, 

 underside covered wdth a beautiful white indumentum of small 

 waxy papillae, usually 2-pinnate and pinnatifid. Lowest primary 

 pinnae longest, 2-4", with the lowest basiscopic secondary pinna 

 two-three times longer than the others and generally pointing back- 

 wards, pinnatifid with oblong rounded lobes. Sori at first small 

 globose in an almost continuous line close to the margin, finally 

 confluent. Edge of frond thin and simulating an indusium, sometimes 

 covering the sori. 



Kavines and damp hillsides, very common in the hill districts. All districts 

 of Chota Nagpm-, ascending to top of Parasnath ! Kajmahal Hills ! Angul, 

 Chattarjee ! Fr. Sept.-Jan. 



16. DORYOPTERIS, J. Sm. 



Rhizome short or creeping, the black polished stipes clustered or 

 scattered with diarch or triarch vascular bundles, scales with pro- 

 nounced central band. Fronds often dimorphic, simple or pinnatifid, 

 and the basiscopic side of segments more strongly developed ; tri- 

 angular ovate in outline. Veins copiously anastomosing without 

 free included veinlets. Sori marginal as in Pteris. 



1. D. ludens, J. Sm. Syn. Pteris ludens, Wall. 



A small fern with creeping rhizome furnished with linear adpressed, 

 white-margined brown scales. Stipes scattered, with sparse scales
