A very remarkable-looking plant, native of the Arabian de- 

 serts, and first noticed by Forskahl, in his « Flora iEgyptiaco- 

 Arabica.' It was, prior to 1846, introduced, in a living state, to 

 the Horticultural Society's Garden, through the medium of the 

 Directors of the East India Company, from Aden. Several 

 healthy plants were kindly sent to us also from Aden, by J.
