5 2 Ferns of British India and Ceylon. 



decipiens, I fear, is not always constant in its deltoid form and 

 runs into the type. Dr. Watt has collected glanduligera abun- 

 dantly in Munipore (pinnse often very narrow and pinnules 

 revolute). Mr. Mann sends very fine specimens of the same from 

 Sebsagur, in Assam, the frond with stipe nearly 30 inches long, 

 the pinnules sharply lobed at the margins, Mr. Day also col- 

 lected it in Perak. 



I exclude Clarke's var. hirsutipes and describe it as a species 

 as the rhizome is erect and the sori basal or medial on the veins. 



8a. Lastrea hirsutipes. Rootstock apparently erect, with, 

 tufted stipes ; stipe hirsute, rather densely so at the base, that of the 

 fertile fronds much elongated (15-20 inches long) ; fronds lanceolate 

 10 inches or more long by 4-8 inches broad, texture coarser than 

 in gracilescens and drying rather black, the fertile often more or 

 less contracted ; the pinnse cut down two-thirds or more towards 

 the costa into oblong blunt segments, which are a little hairy both 

 on the veins and lamina above, the costas densely clothed with 

 rather short hairs ; veins all simple ; sori large, basal or medial on 

 the veins in two rows close to the midrib, indusium hairy, often 

 didymochlaenoid. Neph. gracilescens var. hirsutipes, Clarke, 

 F.N.I, p. 514. Khasia and Jaintea, 4,000-5,000 feet alt.; also 

 var. didymochlaenoides I.e. Khasia Sohra Coalhill 4,300 feet 

 alt., which only differs in the stipe being less hairy and the invo- 

 lucres being larger. This fern does not appear to have been 

 gathered except by Mr. Clarke. I have only seen a few specimens, 

 and hope it will be searched for. 



8b. Lastrea thibetica. {Franchet.) Rhizome ? stipes about 

 6 inches long, furnished with narrow-lanceolate fulvous scales ; 

 fronds about 2 feet long by 7 inches broad at middle, attenuated 

 at the base, papyraceous, pale green, pinnate ; rachis angled, 

 furnished with linear scales ; pinnae 25-30 sessile narrow lanceo- 

 late from a scarcely broader base, acuminate, patent, slightlv 

 falcate, the veins underneath pubescent, lobed down about J of 

 the way to the rachis ; lobes ovate, rounded, obsoletely toothed ;
