 y^ARJEELING, in the Sikkim portion  of  the  Himalaya,  the  native  country of  the  plants figured and described  in  the  
 Mowing  pages,  is  situated  in  lat.  27° N., and long, the  same  as  Calcutta,  from  which  it  is  distant  about  880  miles.  
 Its elevation above the sea is 7,200 feet.  The  mean  temperature  of  the  year is about 55° of Fahrenheit, and that of each  
 month,  as  detailed  in  a  Calendar  communicated  by  Dr. Campbell, the Hon. the E.  I.  C. Resident at Darjeeling,  to  the  
 late Lord Auckland,  and now lying before me, is as follows 
 January 41* May 59° September 
 February 43° June 64° October  .

 “ In five years,” further observes Dr. Campbell,  “ there  have  been  three  heavy  falls  of  snow:  one  in  December,  1842 ;  
 one in January,  1839;  and one in February,  1841.” 
 The  mountain  Sinchul,  upon  a  spur  of  which,  looking  north,  Darjeeling  stands, attains an elevation of 9,000 feet,  
 and to the west of it, next Nepal, rises another conspicuous mountain, Tonglo, reaching a height of 10,000 feet.  Due north  
 of Darjeeling, at a distance  of  only  sixty  miles,  the  horizon  is  bounded  by  the  great  snowy  range  (as seen, or rather  
 attempted to be shown, in the vignette of the title-page), having for its principal feature the peak of K in c h in - ju n g a ,  which  
 has lately been ascertained to be 28,172 feet in elevation, the loftiest mountain  yet  known in the world.  Dr. Hooker thus  
 describes his first impressions of this  scene:—“ Much as I had heard and read of the magnificence and beauty of Himalayan  
 scenery, my highest expectations have  been  surpassed!  I arrived at Darjeeling on a rainy  misty  day, which did not allow  
 me  to see ten yards in any direction,  much  less  to  descry  the  Snowy Range,  distant sixty miles in a straight line.  Early  
 next morning I caught my first view,  and I literally held my breath in awe and admiration.  Six or seven successive ranges  
 of forest-clad mountains, as  high  as  that  whereon I stood (8,000 feet), intervened between me and a dazzling white pile of  
 snow-clad  mountains,  among  which  the  giant  peak  of  Kinchin-junga  rose  20,000  feet  above the lofty point from which  
 I gazed!  Owing  to  the  clearness  of  the  atmosphere,  the  snow  appeared,  to  my  fancy,  but  a  few  miles  off,  and  the  
 loftiest mountain at only a  day’s  journey.  The  heavenward  outline  was  projected  against  a  pale  blue  sky;  while  little  
 detached patches of  mist clung  here  and  there  to  the  highest  peaks,  and  were  tinged golden yellow, or rosy red,  by the  
 rising sun, which touched these elevated points long ere it reached the lower position which I occupied.
