'PHE FERJStS OF NORTH-WESTERN INDIA. 729 



The following are extracts from Kunze's description :— 



" 761, b— frondelanceolata, coriacea, pinnato-profundepinnatifida, 



pinnis alternis approximatis, horizontalibus, oblongis acnminatis ; acunune inciso- 

 serrato, laoiniis imbricatis, oblongin, truncatis subparallelogrammis, margin- 

 atis, apioe falcato irregulariter argute dentati? ; soris inter costulam et 

 marginem meJiis ; costulis costisque subtus laxe ; rhachique stipitique 

 sulcatis utrinque dense fusco-giandi-paleaceis. " 



" E regno Mexicano miserunt Hegewisch et de a Kawiuski (Herb. Leucse 

 anum). 



** Ad Preslii Lastreas ^s 2. Thelypteris pertinet, et A. filici-mari Sw. prope 

 accedit. Differt vero : fronde coriacea, pinnis approximatis, laciniis 

 imbricatis trimcatis apice argute dentatis, soris costulse minus approximatis, 

 paleis frequcntibus, eloogatis, indusiisque fuscis. Aspichum paientissimum 

 Wallich : fronde coriacea, pinnis approximatis, rhachique paleacea conveniens, 

 differt laciniis majis elongatis, basi latioribns, apioe distantibus. Laciniis 

 basris abrupte majoribus, incisisve, et forme laciniarum differunt. " 



a. Forma Ichasiana. 

 N. Filix-mas, Rich., var, vi Khasian-i, Clarke in ' Review,' 519, t. 69, tig. 1, 

 " Stipe and main rhachis with many linear blackish scales ; frond oblong- 

 lanceolate, very little narrowed at base ; pinna; approximate, patent, the lowest 

 equal-sided, cut down to the midrib ; secondary pinnse narrowly oblong, very 

 close and regular, glabrous beneath, rounded, finely serrulate at the apex ; 

 sori not large."

Clarke's type specimens of h'.s var. khasiana in the Kew Herbarium seem very 

 distinct from N. patentisit7nuin,Wa\\.; but in the Journ. Linn. Soc, 1n89, p. 94, 

 referring to the specimen from Kohima cited above, he says : — " This is very 

 large, and not distinguishable from some of var. patentissima (sp. Wall.) from 

 the Central Himalaya. The Khasi examples of var. patentissima have a soft, 

 thick stipe with pale yellow-brown scales." One of the Mackinnons' specimens 

 from Tehri Garhwal also is longer than most ; frond 25 in. 1., by 9| in. br 

 near the base ; lowest pair of pinnse almost 1| in. br. ; and another is but 16 

 in. 1., by 8^ in. br. at base. Mr. G-amble's specimen is 19^" x 8|" ; but 

 Mr. Blanford's is only 15 in. I., by 4^ " br., and it may not be Mr. Clarke's 

 plant.
