Mr. Jackson’s Account of Ormosia, 359 
nigrá maculá notato, of Plumier's Catalogue, and unpublished MSS. 
tom. 7, tab. 145 excepted ; my first care was to endeavour to find 
out whether it might not be the same. That it was not the plant 
of Plumier I was well aware, a copy of his drawing of that, with 
many others of his unpublished drawings, being in the Sherardian 
collection at Oxford, and from which I had taken copies my- 
self for Mr. Lambert. I was, however, still uncertain about the 
plant of Aublet, very erroneous and even heterogeneous syno- 
nymy being often adopted by the botanists of that age with very 
little scruple. Fortunately, however, his herbarium was at hand, 
being now in the possession of the Right Honourable Sir Joseph 
Banks; and on being favoured by Mr. Dryander with a sight 
of Aublet’s original specimen, I found that Mr. Lambert’s plant 
was the identical Robinia coccinea. Characters exactly similar I 
have since discovered in another nondescript plant from Guiana, 
communicated to Mr. Lambert by Mr. Anderson of St. Vincents ; 
and also in the Sophora monosperma of Professor Swartz's Prodro- 
mus and Flora Indie Occidentalis, of which the Pseudo-acacia 
ingens fructu coccineo, &c. of Plumier's drawings, above mentioned, 
is a very good representation ; a plant essentially differing both 
from the original Sophora of Linnzus and the Virgilia and Po- 
dalyria of Lamarck, to the latter of which it has lately been re- 
ferred by Mons. Poiret, as well as the Edwardsia of Mr. Salis- 
bury, a very curious species of which, from South America, 
communicated by the late Professor Cavanilles, is also in Mr. 
Lambert’s collection. From these three species, therefore, agree- 
ing in habits and characters, and natives of nearly the same lati- 
tude, I have constituted a new genus, the characters of which, 
accompanied with sketches from the dried plants, I have now the 
honour to lay before the Society. The name Ormosia, by which I 
have distinguished it, is formed from the Greek Oguas, monile, a 
342 necklace ;
