glaucous. It loses its leaves in the winter, and in its native country 
is probably quite denuded at the time of flowering. The petals are 
erect at first, but soon become reflexed. It is not unlike the Caroli- 
nea alba of Hooker’s Exotic Flora, but that plant is of much larger 
owth.” Notwithstanding this latter ci tance, we cannot observe 
a sufficient difference etek these plants to warrant our considering 
them as distinct species. The number of the subordinate parts of the 
pistil and the degree of development in the lobes of the stigma are 
very variable characters; but beyond these, the chief difference in our 
descriptions of the present flower and that of Dr. Hooker, consists in 
our specimen having the inner surface of the Calyx and petals clothed 
with a velvety tomentum. Dr. Hooker has noticed the close resem- 
blance which exists between C.alba and C. insignis, the flowers of the 
latter however being twice the size of the former, and the tomentum 
on the petals notin fascicles. The flowers of our plant are still smaller 
than those of Dr. Hooker’s, and although the tomentum is distinctly 
fascicled in many places, yet in — it loses this = probably 
from the fascicles being so much 1 that they distinctly 
LLGat co 
observed. From these circumstances we cannot help suspecting that 
C. alba may after all be a dwarf form of C. insignis. Dr. Hooker 
remarks (apparently from examining the ovarium only) that “in hay- 
ing-cells to the fruit, this plant departs from the generic character of 
Carolinea” and he has figured the ovules attached in several rows to 
a large central placenta. But it may be observed that this central 
placenta readily separates into as many subordinate portions as there 
are dissepiments, forming so many distinct placente at their inner edge, 
to which the ovules are attached in double rows. So far then as the 
examination of a dried specimen may enable us to judge, these separ- 
ate placentz do not cohere into a solid central column. It seems there- 
fore extremely probable that in the ripened capsule both the dissepi- 
ments and central mass may be so far obliterated or modified, as to 
give the pericarp the character of a unilocular fruit, as in the other 
species from which the generic character has been framed.
