DR. HOOKER ON THE VEGETATION 
Mr. Mann’s account of the first of these ascents has already 
been read before the Society; he commenced the expedition on 
the 28rd March, 1860, and reached the summit on the 3rd April, 
where the temperature fell to 89° at night. The return was 
accomplished on the 13th of the same month. A second ascent 
was attempted on the 7th of November, and after eighteen days 
he had nearly reached the top, when his men rebelled, and he was 
obliged to return to Clarence. He started a third time, and 
reached the summit in December, but the dates and detailed 
narrative of this ascent have not yet arrived. 
The following notes chiefly refer to the temperate plants, all but 
one of whieh (Sanicula Europea) were collected at or above 5000 
feet elevation. They amount to 76 species (in 66 genera), a 
singularly small number for 5700 feet of vertical height almost 
under the equator. Of these fully 20 are tropical types that 
ascend a little above 5000 feet, and must be excluded from the 
temperate flora. The remaining 56 belong to no fewer than 45 
genera; proving the flora to be an extremely fragmentary one. 
Of the total 76, 37 are Abyssinian species, and 16 others closely 
allied to such; and of the 56 temperate, 32 are also natives of the 
mountains of Abyssinia, most of them being absolutely specifically 
identical, and others but slightly differing; such differences being 
in some cases doubtless apparent rather than real, and owing to 
the want of a larger suite of specimens; 13 others also are very 
closely allied to Abyssinian species. 
Again, of the Abyssinian mountain plants common to Clarence 
Peak, no fewer than 17 are absolutely peculiar to these two 
localities as far as is at present known, including some very re- 
markable plants; as 
Clematis Simensis 
Thalictrum rhynchocarpum 
Sagina Abyssinica 
Trifolium subrotundum 
Stachys aculeolata, n. sp. 
Pycnostachys Abyssinica 
Calamintha Simensis 
Cyanotis Abyssinica ? 
Simense Kyllingia macrocephala 
Helichrysum chrysocoma Trisetum lachnanthum 
—— Hochstetteri Festuca Schimperiana 
—— globosum 
Gymnandropogon, sp. 
Bleeria spicata 
Besides these are the following, 
which are not found south of 
Abyssinia in Africa :— 
Galium rotundifolium 
Deschampsia czespitosa 
Parietaria Mauritanica 
Brachypodium sylvaticum.
