Ki The Miiiiiiluif Tundra at the Edge of the 1' The vegetation of the cliff tops develops into zones similar to those found around ponds, but in this case the zones depend on the depth of the soil and the exposure. The front rock is nearly bare, but supports a few foliose lichens (Parmelia sp.), a few small mosses seldom found in fruit, with occasional stunted stragglers fi'om the next zones. The outermost zone of vegetation is the lichen formation. It ex- tends from the bare rock back until the soil has reached a depth of about a decimeter, when it gives way to the Vacciniuin zone. The characteristic plants are: Cladonia spp. Polytricum spp. Lechea minor Panicum sphaerocarpon Car ex (two or three species, in- cluding C. triceps.) Houstonia Jonflifolia There are also numerous waifs from other associations. On this account the composition of the zone varies greatly from place to place.
