 and a new species, Coleus clivicola. 



10,000 to 11,000 feet: This is the zone of moss par 

 excellence. It forms round cushions on the trees (most 

 of them Erica arborca), and masses 2 feet deep on the 

 ground and amongst the fallen logs, where the h3^raxes 

 make their burrows. Two tree-lobelias [L. Deckenii 

 and L. Stuhlmanni) appear at this level, also a fine 

 tree-hypericum with a big yellow flower. A blue 

 violet {Viola abyssinica) is found in the more open 

 spaces. At 11,000 feet were found two new species, 

 Conyza niontigcna and Calannntha parvula, and the 

 widely spread northern temperate Cerastiurn vulgare. 



11,000 to 12,000 feet: Helichrysums (including a new 

 species, H. IVollastoni), tree-lobelias, tree-heaths, and 

 tree-senecios, are the most conspicuous plants at this 

 altitude, though the two latter attain their greatest 

 growth above 12,000 feet. A handsome Rubus (R. runs- 

 sorensis) with a pink flower and a large but tasteless 

 fruit is fairl}^ abundant, and a small Sedum (S. ruwen- 

 zoriense, sp. nov.) grows on the rocks. The plants 

 found at 12,000 feet include Alchemilla geranioides, 

 Alchemilla argyrophylloides (a new species), Senecio 

 sycephyllus, the tree-senecio 5. adnivalis, and several 

 Alpine species, which have been found on the mountains 

 of Abyssinia and Kilimanjaro — Ranuncidus oreophytus, 

 Cardamine obliqua, and Hypericum keniense. 



12,000 to 15,000 feet: The tree-heaths cease about 

 12,500 feet, but the senecios continue much farther, 

 in some places above 14,000 feet. A fourth species of 

 Lobelia [L. Wollastoni, allied to L. Rhyncopetalum from the 

 mountains of Abyssinia) appears at about 12,500 feet, 

 and is found growing on the steepest slopes almost up 

 to the snow-line. L. Deckenii, which grows only on 

 the level terraces in verj^ moist ground, does not occur 

 above 13,000 feet. Helichrysums, sometimes forming
