566 BOTANICAL EXCURSIONS 
Brown, the highest of all authorities on botanical questions, 
did not find, in the collections from Congo, a single ex- 
ample of any of the tribes most characteristic of the Cape 
vegetation. 
NOTES TO CHAPTER I. 
(A) Here, in particular, is found a rare and curious moss, first discovered 
by Mr. Harvey, and named hy him Wardia Aygrometrica.* It grows plenti- 
fully on the steep face of this rock, where it is constantly wet. Harvey found 
it also in astream on the opposite side of the Table Mountain, and at the 
Drakensteen waterfall, in the district of Stellenbosch. 
(B) The following are some of the most remarkable plants which I gathered 
on and near the summit of Table Mountain, in my first ascent 
Disa grandiflora, D. ferruginea, D. tenuifolia, Gladiolus brevifolius (of Ja- 
quin), Penea mucronata (very plentiful), Hermas villosa, Crassula coccinea, 
Erica glutinosa, E. coccinea, Teedia SC? Osteospermum ilicifolium, Spheno- 
udicaulis, Todea Africana, Schizea pectinata. 
In November, I collected there : 
, Erica sexfaria, E. sees E. petiolata, E. brevifolia, E. 
tubiflora, gaz: nsis (of Harv Grubbea rosmarinifolia, Pterygodium 
aetatum, Ce [SERA (st: De Candolle), H. Seri (De C.) 
enecio verbascifolius, Eurvops pectinatus, Villarsia ovata, Penea Sarcocolla, 
Staavia glutinosa, nsn Sarniensis, and numerous Restiacee. 
That pretty and well known grass, Briza mazima, a native of the South of 
rope, grows rather plentifully on the top of Table Mountain, a fact which 
seems adverse to the opinion of those who consider it as merely naturalized at 
the Cape. It is common in the neighbourhood of the town. 
(C) The upper part of this'mountain is kept almost constantly moist, during 
even the greatest heats of summer, by the clouds which rest on it, and is 
very favourable to the growth of mosses, which, in the valley below, 
are to be met with only during the wet season, and then but sparingly. A 
— but curious mass, the dndrea subulata, one of T. Harvey's disco- 
veries, grows on the rocks in the gorge of the mountain ; Jungermannia Hy- 
Keess (t Hooker) occurs in the same situation, ed overhanging 
rocks, where there is a continual drip of water; on the summit there is abun- 
dance of Trichostomum lanuginosum and Dicranum flexuosum, (two of the
