on the Andes to 10,800, and it is marked by escallonia 
myrtilloides, aralia avicennifolia, and drymis winteri ; on 
the mountains .of Mexico to 12,000 feet, and is marked by 
pinus montezumz; 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 ot 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
