approximate, and his description of the appearance of the leaves is just 
the reverse of that given in the Flora Capensis, where the leaves of 
A. 'purpurascens are called glaucous. Our observations on wild and culti- 
vated plants agree with the latter statement, for the leaves of A. succotrina 
are more greenish than those of A. pwyurascens, although we have both 
plants growing side by side. 
The illustrations which come nearest to the appearance of the wild 
plants are A. succotrina, as represented in DeCandolle, Plantes grasses, 
tab. 85, and for A. purpurascens, as shown in Curtis Bot. Mag., tab. 1474, 
while both figures of Salm Dyck (vol. iv., sect, xxii., figs. 1 and 2) repre- 
sent intermediate forms. 
The colour in the figures cited has changed, for these books were 
published about one hundred years ago. The flowers of A. succotrijia are 
a deep red, with small green tips, while those of A. pitrpurascens are 
somewhat paler, and the green part of the inner as well as outer segments 
is at least three times as large as in the other species.

Aloe Thraskii, Baker (Flora Cap., vi., 328). 
The original description of this species was made from a plant culti- 
vated in England (introduced by Cooper, 1860). As usual with our 
succulents, such plants are weaker, more elongated, and their inflor- 
escence poorer than of those growing under natural conditions. A. 
Thraskii occurs on the coast of Natal — e.g., at Umkomas — as a stout 
tree, 6-10 feet high, with leaves nearly twice as large as stated in the 
description, viz., 3^-4 feet long — in fact, they are the largest in the genus, 
even exceeding those of vigorous specimens of A. Bainesii. The inflor- 
escence is not simple, as stated in the original description, but much 
branched, bearing from 5-10 erect stout spikes of reddish-yellow flowers, 
and there are generally two, or even three, such inflorescences on each 
plant. 
A showy and very ornamental plant, flowering in my garden at 
Capetown in June.
