I spoke of the Angrecum eburneum (see our Tab. 4761) with 
admiration on account of its noble aspect. But it shrinks into 
insignificance in comparison with the present Madagascar rarity, 
known to botanists only through the figures above quoted of 
Aubert du Petit-Thouars (published about 1822), till the Rev. 
William Ellis, the distinguished traveller and historian of Mada- 
gascar, on his last return from that wonderful island, made us 
acquainted with the living plant, which that gentleman has twice 
flowered, first in 1857 , when the interesting account and figure ap- 
peared in the ‘ Gardeners’ Chronicle,’ and now again in the winter 
(February) of 1859, at his residence, Hoddesdon, Herts. ‘There 
our figure was taken, and though not one of the figures quoted, 
not even the original ones of Du Petit-Thouars (though there 
* In neither of these two works of M. Aubert du Petit-Thouars is there any 
description of the plant. The first of them stops short at the thirty-second page, 
and before any descriptive matter of the genera and species appears, and Pritzel 
notices this deficiency. Of the second work, in large folio, with six coloured 
figures of Orchideous plants of Madagascar (presented to me by the author, and 
pare never published), Pritzel has no record, nor of any work in folio by 
1s author.
