Smith, W. W. and G. H. Cave. The Vegetation of the Zemu 

 and Llonakh Valleys of Sikkim. (Rec. Bot. Surv. Ind. IV. 

 p. 141—260. 1911.) 



The first 20 pages of this paper are given up to an account of 

 the various days' marches which, including as it does, notes on the 

 preliminary preparations, on the practicability of the various routes, 

 etc. should prove useful to intending travellers in this part of N.W. 

 Sikkim. In a chapter on the general aspect of the Llonakh flora 

 the Vegetation is treated under three heads: I. plants of the open 

 flats and marshes. IL those of the moraines and screes and III. the 

 extreme alpines of the Upper cliffs. Thereafter follows a general 

 survey comprising a brief review of the chief natural Orders and 

 genera above 11,1)00 ft. and treating of their habitat and relative 

 frequency. So far the paper is the work of the Joint authors but 

 the concluding chapter devoted to the systematic enumeration of 

 the plants collected is entirely by W. W. Smith who describes 

 the following new species: Clematis semuensis, Cochlearia (?) serpens, 

 Arenaria thangoensis, Astragalns semuensis, Potentilla perpusilloides, 

 Saxifraga llonakhensis, S. Caveana, S. coarctata, S. iuconspicua, Cre- 

 manthodium cucidliferum , Primula atrodentata, P. Caveana, P. fla- 

 gellaris, Eritrichium(?) acaule, Aphyüorchis Pantlingii and Allinm 

 Gageanum. Besides the above Burkill describes a new genus of 

 Gentiatiaceae with one species Parajaeschkea Smithii and the fol- 

 lowing names of new species without descriptions appear: Pedi- 

 cidaris Smithiana, Bonati, Sedum Smithii, R. Hamet, 5. Cavei, R. 

 Harnet and Sedum Quevai, R. Hamet. Accompanying the paper is 

 a map on a scale of 4 miles to an inch showing the routes followed 

 and also reproductions of photographs of Llonakh and Zemu 

 Valley. W. G. Craib ;Kew).
