32. Pleopeltis juglandifolia. Munipore, 7,500 feet. 

 {Watt.) 



Small undivided and trifid fronds often occur in this, as in 

 trifida and himalayensis ; var. pauper, Clarke, /our. Linn. Soc. 

 xxiv. 418, is described from these simple fronds. Fronds with 

 solitary and with twin sori may be found on the same plant, so 

 that Clarke's biserialis cannot be considered as a variety. 



32. Pleopeltis Lehmanni. Khasia Hills, 5,000 feet alt. 

 {Mann.) 



Mr. Baker considers this species a variety of himalayensis ; 

 but the fronds are more membranous, the pinnae narrower, and 

 without the hyaline margin ; I have not seen intermediate forms. 



34. Pleopeltis himalayensis. 

 (Also in Western China.) 



[Pleopeltis Wardii. {Clarke, Jour. Linn. Soc. xxv, p. 99, 

 tab, 43.) "Rhizome creeping, furnished with many soft lanceolate 

 spreading yellowish-brown scales ; stipes naked, 6-18 inches long ; 

 fronds 1-3 feet long, pinnate ; pinnae broadly lanceolate caudate, 

 margin hyaline undulated ; main veins parallel, 30-40 on each 

 side of the costa ; sori large in a single series between the main 

 veins, 1-6 between the costa and margin. Kegwima Edge, 7,000 

 feet alt. ; Naga Hills. I cannot regard this as anything but 

 luxuriant himalayensis. Mr. Clarke considers it a distinct species 

 on account of the uniseriate character of the sori ; I have speci- 

 mens, however, of himalayensis showing both forms on the 

 same plant, and the same variation occurs in juglandifolia ; I 

 do not see that it can even be made a variety.]
