there are not unfrequently lateral, axillary peduncles, each 
resembling one of the rays or branches of the umbel. Invo- 
lucre cup-shaped ; its glands five, oval, fleshy, yellowish- 
green, dilated into a petaloid, large white membrane, so 
that the involucre looks like a five-petaled corolla. Mr. 
Nourratt observes, that these involucres are dicecious. In 
the plant here figured they are only pistilliferous ; whilst 
native specimens in my Herbarium, sent me by Mr. Nour- 
TALL, and from which the dissections were taken, seem to 
be almost wholly antheriferous (fig. 1.) ; for I found a few 
of the flowers bearing pzstils, though mixed with very im- 
perfect stamens. Staminiferous flowers as in most of the 
Genus, only some of them appear to be combined by their 
pedicels. Germen three-lobed, greenish, slightly warted? 
Styles three, bifid, purplish. 
Cultivated by Rosert Barctay, Esq. at Bury Hill, whence 
that most liberal admirer and patron of Botany commu- 
nicated the drawing here given. The plants flowered in 
the open air in July, and were raised from seeds sent from 
North America, by Mr. Nurraty. According to Linnzus, 
it inhabits Canada, and thence extends as far south as the 
Carolinas. 
It is one of the most remarkable of that extensive and 
curious Genus Evpnorsia; and the appendages of the 
glands of the involucre might, if not examined with some 
care, be taken for the white, spreading petals of a corolla.
