central column, thus dividing the base of the involucre into five com- 
partments ; erect fimbrie arising from their margins partially divide 
the upper part of the involucre into a similar number of cells; teeth 
of the involucre numerous, connivent, whitish, woolly on the inner side; 
near the top of the inyolucre are several appendages, or nectaries, of 
which four are abortive and one perfect, which is round, entire, peltate, 
and so constructed at the margin, as to appear two-lipped. SvTamni-— 
FEROUS FLOWERS about 10-12, in double rows in each compartment 
of the involucre, from the base of which they spring, each accompanied 
with a scale, which is hairy towards the top; monandrous. STAMENS 
articulated on small pedicels, filaments whitish, anthers two-lobed, 
yellow. PisTILLIFEROUS FLOWERS solitary, central, supported on a 
short stalk, naked, ovary three-lobed, styles three, each style — (?)

Poputar aNp Grocrapnicat Notice. This variety was dato: 
yered about 400 miles from the city of Mexico, by Wm. Bates, Esq., 
by whom it was sent to Charles Tayleure, Esq., Toxteth-Park, near 
Liverpool. Whether it is a distinct species, or merely a variety of pul- 
cherrima, is somewhat doubtful; we deem it safer to regard it only 
as a variety, rather than create new species on imperfect data. Poin- 
settia pulcherrima was in flower in the Liverpool Garden, at the same 
time, a coincidence which further disposes us to think that they are 
the same; and this view we are happy to have strengthened by Pro- 
fessor Graham, who has carefully compared both plants. A white 
milky juice, flows from any wounded part. Large drops of clear sweet 
~ fluid collect at the mouth of the nectariferous appendix. gee

which our drawing was made in December, was obligingly supplied 
from the Garden of the Liverpool Botanical Society, to which it had 
been presented by Charles Tayleure Esq. This gentleman had also 
received the red-bracted Poinsettia pulcherrima from Wm. Bates, Esq. 
previous to its introduction from Philadelphia by Mr. James Me Nab, 
so that it was by his exertions in the gardens of England before the 
specimen from which the drawing in the Botanical Magazine, 3493, was 
made. It should be kept in a cool stove or warm AOE
