of these cedars, which cover all the uncultivated regions. 

 This tree is also called the pencil cedar, although the 

 wood does not appear to be used at present in the manu- 

 facture of lead-pencils in England. It is much prized 

 for ship-building. Reid thinks that the Bermuda cedar 

 does not occur in the hot climate of the West Indies, but 

 it is very common on the mountains of Jamaica. 



V. AMERICA. 



The plants collected by Simpson and Dease, in their 

 voyage of discovery on the arctic coast of America, have 

 been named by Sir W. Hooker (Narrative of the Disco- 

 veries on the North Coast of America, by T. Simpson. 

 London, 1843, Svo, Appendix). These plants had, how- 

 ever, been previously found in Eranklin's travels in the 

 same region, and admitted into Hooker's Flora of British 

 America, with the single exception of Salix nivalis 

 Hooker, which was discovered by Drummond on the 

 Rocky Mountains, and occurs also on the coast below 71 

 N. lat., west of Mackenzie. 



A coast-landscape of Unalaschka, by Kittlitz (pi. IV), 

 represents luxuriant meadows, in which various subalpine 

 shrubs, forming most luxuriant thickets of plants, are 

 intermixed with strong turf composed of Cyperaceae : 

 amongst the former are Aconitum, Heracleum, JEpilobium, 

 and especially Lupinus. The dwarf shrubs, also, of the 

 alpine region, Salices and Rhododendron Kamtschaticum, 

 extend on these islands, which are situated beyond the 

 tree-limit, into the vicinity of the sea. Two views of the 

 island of Sitcha, the forests of which they represent (pi. 

 II and III), may serve as contrasts. They give a dis- 

 tinct representation of the mixed foliage of the Canadian 

 larch (Pinus Canadensis) and a species of pine (P. Mer- 

 tensiana), the growth of Panax horridum, the palmate 

 auricled leaves of which are sometimes crowded together 

 upon a turfy kind of brushwood, at others upon shrubby
