58 Ferns of British India and Ceylon. 



margin ; sori apical or towards the apex of the veinlets. Lastrea 

 assamensis, Hope, four. Bot. 1890. 



Nambur Forest, Assam. (Mann.) Mr. Hope also gives as 

 localities Lukhimpur, in the Upper Dehing Forest ; Garo Hills, 

 1,000 feet alt. ; and he states that the lower pinnas are sometimes 

 not reduced ; it comes nearest to Moore's odontoloma. Mr. 

 Baker informs me that it is very close to some of the European 

 forms of the type of Filix-mas. 



Var. Schimperiana.'\ The typical form of this is well 

 marked, though I formerly followed Sir W. Hooker in including 

 it under elongata ; it is intermediate between cochleata and 

 odontoloma. (Moore.) There are two forms in N. India, a 

 large and a small variety. I have only seen the latter (L. inter- 

 media, Bedd. F. S. I. tab. 113) in Southern India. In the Kew 

 Herbarium there is a specimen collected by General Strachey 

 which is intermediate between this and elongata, i.e., the habit of 

 elongata with the very large sori of this variety, and a specimen 

 collected by Colonel Bates above Simla, quite intermediate 

 between this and cochleata. 



Var. lachoongensis. Stipes 8-9 inches, densely clothed 

 towards the base with orange-eoloured very thin lanceolate hair- 

 pointed scales ; fronds elongate-deltoid, about 2 feet long ; pinnae, 

 the lower pair 4-5 inches long by i-J- inch broad, gradually 

 decreasing upwards, cut down to the base or nearly to the base 

 (leaving a very narrow wing to the rachis) into oblong blunt seg- 

 ments, which have a broad square base, about 1 inch long by f inch 

 broad, nearly entire, except the rather sharply-toothed apex, or in 

 some of the lower larger ones a tendency to become pinnatifid ; 

 veins very deeply chanelled, especially on the lower surface ; sori 

 very large, in a single row on each side of and close to the midrib. 



Lachoong, in Sikkim, at 12,000 feet alt., collected by Mr. 

 Levinge's Bhootea collector. (Burr.) Lachen, 9,000 feet alt,
