Directors *. To that istitution it was sent, with many other 
rare plants, from Rio Janeiro, in the autumn of 1822, by Mr 
JOHN F’orBEs, a most meritorious collector to the Society, 
who afterwards proceeded upon a mission into the interior of 
Africa, where he died as he was proceeding up the Zambezi 
river, in the 25th year of his age, to the irreparable loss of. 
‘science, and to the great grief of his employers. 
This plant struck me as bearing so much similarity in its 
parts of fructification to those of our Malawis paludosa, that 
I should have been induced to refer it to that genus, if my va- 
lued and able friend Mr LinpLey had not expressed himself 
of a different opinion; and as that gentleman has devoted 
much attention to the Orchideous plants, with a view to pub- 
lishing a History of that tribe, his ideas are entitled to the 
highest respect. 
The following remarks were kindly communicated to me 
by Mr Lrypiey, along with his generic character of Pres- 
cotta. “ Strongly resembling this plant in habit, especially in 
its minute green flowers, is a singular individual, of which I 
possess specimens from Mexico, and which is still more nearly 
related to Malawis, as it agrees with that genus in its sec- 
tional character. I call it 
PepILea, (from wed:aov, a shoe). Perianthum rectum 1 (resupinatum aucto- 
rum). Lacinice ovate ; due labello suppositee, ceeterae (quorum interiores 
lineares) dependentes. Labellum erectum, ovatum, calciforme, integer- 
rimum, apertum. Columna quadrata, minutissima. Anthera terminalis, 
opercularis, decidua, bilocularis. Pollinia bina, cereacea. Gyniza por- 
rectus, subquadratus, tridentatus. . | 
“ T have given the name Prescoria after our friend 
JOHN Prescot, Esq. of St Petersburg, who is known no less 
by his acquaintance with the more minute departments of bo- 
tany, than by the facilities which he affords to communication 
between men of science in this country and in Russia.”
