A native of Sierra Leone, whence it was introduced about the 

 year 1834, by Messrs. Loddiges, in w4iose nursery at Hackney it 

 flowered for the first time in this country in August of the 

 following year. It appears to have been subsequently imported in 

 limited numbers, as it was generally cultivated by the most pro- 

 minent amateurs of the period 1840 — 60,* among whom it was in 

 high repute on account of its very curious flowers, of which the 

 unusual colour, the long tails, and the remarkable sexual apparatus 

 are striking peculiarities. It has since become quite rare in British 

 gardens, and at the present time it is represented in but few 

 collections.
