For this pretty and singular plant we are obliged to Messrs. Loddiges, who sent it us in the middle of last Decem- 
ber. We incline to believe that if the plant had flowered at a more favourable time of the year, it would have 
been much more handsome than it was when we made our drawing. Messrs. Loddiges inform us that they are un- 
certain from what quarter they received it, but they think from South America. It is not uncommon in collections 
about town ; and is very readily distinguished by its spotted dull green leaves, and the pale neck of the bulbs, which 
appear to us to be constant characters. 
The only trace we can find of the genus Angrecum of M. du Petit Thouars is in a single plate, intended as a 
specimen of some very extended work upon the Orchide@ of the islands off the south-éast coast of Africa, which 
that most excellent botanist has announced his intention of publishing. For the opportunity of seeing the plate we 
are indebted to our liberal friend Mr. Lambert, who received it from the author with the unpublished part of his 
Plantes des Isles australes d’ Afrique. M. Petit Thouars appears to have employed a method of dividing the genera 
of this order into tribes, which the work we have just mentioned will doubtless explain satisfactorily. But as at pre- 
sent it is impossible to ascertain what that method is, we have ourselves framed a character which will serve to distin- 
guish Angrecum, as a genus, from the others of the same section as at present constituted. The greater part of 
Swartz’s Limodora, when they shall have been submitted to a more rigid examination, will probably be referable 
to this genus ; which, in fact, may rather be considered the same as Limodorum, certain species referred to it being 
excluded. Among these must be numbered the Limodorwm abortivwn of the South of Kurope, which has granular 
pollen, and being the type of the genus must retain the name of Limodorum. 
At first sight, it might be supposed that Vanda and this plant were nearly related to each other, on account of a 
general external similarity of appearance which they possess. We believe, however, on the contrary, that they will 
not eventually be placed in the same section ; for we are persuaded that the parasitical Orchidee with waxy pollen 
are capable of being separated into at least two divisions, distinguished by certain peculiar and important modifica- 
tions of the pollen and its appendages. 
The name Angrecum seems to have originated with Rumphius, who formed it from the word Angrec, an appella- 
tion given by the Malays to parasitical Kpidendra ; but the meaning of which we have not been able to discover. We 
learn from Keempfer that Angurdk is also the name applied by the Japanese to these plants.
