The identification of the different species of Indian and Burmese bamboos is still 

 very obscure and requires considerable research to settle accurately. The large-leaved 

 bamboo of Dehra Dun, the one known as Dendrocalamus Parishii from the Punjab, 

 Bambusa spinosa, Roxb. and other species are mentioned by Brandis as still doubtful. 

 Munro gives long lists of doubtful species, many of which are Indian, while numbers 

 of species are known only by vernacular names. The following, of which Lepcha 

 names are given, have been collected in Sikkim by Mr. E. Fuchs : Pugriang, a mag- 

 nificent species with large thick leaves and stems having a diameter of 5 inches and 

 internodes 18 inches long ; Pogslo, a species with light hollow stem, 2| to 3 inches in 

 diameter and from 3 to 4 feet between the nodes ; Podiam, pshi, pagjiok, pobong, 

 pati, posonff, and bongshing. Lewin, in his account of the Hill tracts of Chittagong, 

 gives the following Bengali names for bamboos, the species of which has not yet been 

 definitely settled. Paia, dolu, Jcullai, boodoom, lota, kata, burria, turrets, while 

 Assam, Cachar, the Khasia, Jaintie and Garo Hills produce many more whose identifi- 

 cation is uncertain.

Tree Ferns are found in the whole of the Eastern and Western moist zones and 

 principally in the Eastern Himalaya, Khasia Hills, Eastern Bengal, Burma and on 

 the Western Coast. One species extends to Central India. 'The Burmese species art- 

 described by Kurz ; those from Ceylon are given in Thwaites' ' Enunieratio, ' while the 

 species from Northern India are to be found in the newly published ' Revision of the 

 Ferns of Northern India' by C. B. Clarke in the ' Transactions of the Liuueau Society 

 1880, p. 425. ' Of true tree ferns there are 4 genera : viz., Cyathea, Hemitelia, 

 AlsopJiila and Brainea. 



CyatJiea contains only one species from the Indian Peninsula, viz. : C. spinulosa, 

 Wall.'; Kurz ii. 572, Clarke p. 429, a small tree of Nepal, the Kkasia Hills, Tenas- 

 serim and South India, attaining 30 feet in height. In Ceylon, however, two or three 

 other species occur, of no great size, the most remarkable of which is the beautiful 

 C. sinuata, Hook, and Grev., with undivided fronds. 



Hcmitclia contains, according to Clarke, two species. H. decipiens, J. Scott, 

 Clarke 430, Gamble 83, is a common species in the Khasia Hills, and the Hills of 

 Sikkim, up to 6,000' feet. Numbers of fine specimens may be seen about Kurseong, 

 and some reach a height of 30 feet, with a rather thin, prickly stem. (E. 3423, Balasun 

 Valley, Darjeeling, 5,000 feet; E 3424, Dumsong, Darjeeling, 6,000 feet). H. Brununi- 

 ana, C. B. Clarke 430 (Alsophila Brunoniana, Wall., A. latcbrosa, Hook, (part) Veru. 

 Unyo, pakpa, Nep. ; Pashien, Lepcha, is a tall, thick-stemmed, handsome tree fern of 

 Sikkim (4,000 to 7,500 feet) and the Khasia Hills (3,000 to 5,000 feet). It is the 

 common species at Darjeeling, and often reaches 40 feet in height. 



In Alxophila, there are, as far as is yet known, seven Indian species, most of which 

 are found in the Eastern Himalaya. A. latebrusa, Hook, (part); Kurz ii. 573; 

 Clarke 431, is found in Burma, while a variety of it (A. Schmidiana. Kze.) occurs in
