EXPLORATION OF ADEN.

mrnosa, Cadaba glandulosa,, continue shrubby, covering beds of tor- 
rents, Cassia lanceolaia and angustifolia , Gynandropsis pentaphylla , 
Cleome angystifolia , Anastatica Hierochuntica , Psoralea bituminosa 
Indigo ferae, spec., Staticis spec., are among the scanty, stunted vegeta- 
tion, which is met with in more protected situations, affording some 
appearance of verdure during one half of the year. Corn and vegetable 
as well as fodder, have all to be imported, partly by sea, from the 
African coast, and partly, in times of peace, from the continent. The 
coast to the westward is less barren than Aden ; here are seen groups 
of palms and of shrubs consisting probably of PUiamnus Napeca , and 
Acacia planifrons. " l 
We have not seen Roth's specimens (if he made a collection at all), 
but considering that his Sterculia urens, Acacia planifrons, Euphorbia- 
triaculeata, Cap par is carnosa, Cassia lanceolata , Gynandropsis penta - 
phylla, Cleome angustifolia, Anastatica Hierochuntica, and Psoralea 
bituminosa have never been noticed at Aden by any other botanist land 
there were a good many of them between 1846 and 1860), we are 
inclined to think that the identification of the plants mentioned was done 
in a somewhat superficial way. It is for this reason, that we did not 
take notice of Roth's names when drawing up the list of Aden plants. 
J. D. Hooker, 1847. — On his route to India in December 1847, 
J. D. Hooker remained two days in Aden, where he made an extensive 
collection of its plants. r l he ‘ Extracts ' from his private letters 2 are 
so valuable that we shall reproduce below the passage relating to Aden 
in extenso. 
For his second visit to Aden, see under f T. Thomson.' 
The plants are in Herb. Kew. 
E. Madden, 1850. Lieutenant-Colonel Edward Madden 3 , of the 
Bengal Artillery, collected a few Aden plants in 1850. They were sent to 
Sir W. Hooker among his general collection and are now at Kew.
