on the Andes to 10,800, and it is marked by escallonia 

 myrtilloides. aralia avicennifolia, and dryrnis winteri ; on 

 the mountains of Mexico to 12,000 feet, and is marked by 

 pinus montezumae ; on the south side of the Himalaya to 

 11,500, and on the north side to 14,000 feet. On the Pyre- 

 nees its limits are marked at about 7000 feet by pinus unci- 

 nata, on the Alps at about 6000 feet by pinus picea, on the 

 Caucasian mountains at 6,700 feet, and in Lapland at about 

 1|500 feet by the birch. Next in order comes the Shrubby 

 region, the limits of which in Europe are marked by rho- 

 dodendrons, which cease on the Alps at 7,400 feet, and on 

 the Pyrenees at 8,332 feet ; on the Andes it is limited by 

 bejaris and shrubby composite, at a height of 13,420 

 feet; on the south side of the Himalaya, by species of 

 juniper, willow, and ribes, at an elevation of 11,500 feet. 

 In Lapland, species of willow and vaccinium, with the 

 dwarf birch, reach 3,300 feet. The next region is that of 

 grasses, which on the Andes and the Himalaya extends 

 to between 14,000 and 15,000. Finally, we come to the 

 region of Cryptogamic plants, which extend to the snow- 

 line, lichens being the last plants met with. , 



' In contrasting the zones of altitude with those of latitude, 

 Meyen gives the following regions of alpine vegetation : 

 The region of palms and bananas (equatorial) extending 

 from the sea level to 1,900 feet ; the region of tree-ferns 

 and of figs (tropical) 1,900 to 3,800 feet; the region of 

 myrtles and laurels (sub-tropical) 3,800 to 5,700 feet ; region 

 of evergreen dicotyledonous trees (warm temperate) 5,700 

 to 7,600 feet ; region of deciduous dicotyledonous trees 

 (cold temperate) 7,600 to 9,500 feet; region of abietineae 

 (sub-arctic) 9,500 to 11,400 feet; region oi rhododendrons 

 (arctic) 11,400 to 13,300 feet; region of alpine plants 

 (polar) 13,300 to 15,200. 



On the Table Mountain range there grows luxuriantly 

 the silver tree (Leucadendron argenteum), the sparkling 

 in the sunshine of the silver-like leaves of which charms 

 the eye of visitors. It grows at a certain altitude, not in
