368 HORTUS MORTOLENSIS 
A, Dawei. 
Only succeeds in very sheltered places. It was grown from 
seeds sent from Entebbe by Mr. Dawe in 1905. 
A. dichotoma. 
One of the giants of the genus; is only represented by a few 
seedlings, which are of slow growth. They came from seeds sent 
from German South West Africa by Mr. K. Dinter. 
A, eru. 
This is the plant almost invariably seen in gardens under the 
wrong name of A. abyssinica. It was re-introduced by Prof. 
Schweinfurth. There are several forms, named by Cay. C. 
Sprenger, Naples, from whom we received the following :—erecta, 
glauca, maculata, and parvipuncta. 
A. ferox. 
Seeds of this species, which, next to A. swpralevis, yields most 
of the drug Aloe,* were introduced to La Mortola in June, 1872, 
by Mr. Daniel Hanbury, probably received from Prof. MacOwan. 
Further, seeds of ‘a medicinal Aloe of Natal, 10-15 feet high,” 
were sent in 1871, no doubt from the same source. From these 
seeds all the tall specimens in the garden must have grown. 
The variety xanthostachys has flower-spikes entirely yellow, 
whilst in the type the buds are red and the open flowers yellow. 
A. Greenii. 
This was received, in 1905, from Mr. I. Lynch, of Cambridge, 
and Prof. 8. Schoenland, of Grahamstown. It grows and flowers 
abundantly, though rather sensitive to cold. 
A. hereroénsis. 
This has been repeatedly tried, but has never succeeded for 
any considerable period. 
A. lateritia. 
Ts rather tender. It has flowers of an extremely fine glossy 
red. We are indebted for the plant to Prof. Dr. A. Engler, 
Director of the Botanic Garden, Dahlem, who brought it from 
Mount Bomule, near Amani, German East Africa, in 1902. 
A. longiflora. 
Belongs to the section “ Principales,” and has yellow flowers. 
It was received from Glasnevin through Mr. (now Sir Frederick) 
Moore, in 1906. 
A. Marlothit. 
Was kindly sent by Dr. R. Marloth, of Cape Town, in 1905. 
It belongs to the section ‘“‘ Pachydendron,” and is allied to A. 
ferox, but has the leaves more prickly on both sides, and the 
branches of the inflorescence spread almost horizontally.
