THE FLORA OF SOUTH AMERICA. 509 
about 4 in. long; the calyx is campanular about 4 lines long 
with 5 equal, 3-angular lobes; the corolla is tubular below, 
somewhat swollen at base around the disc, above it swells 
into a somewhat campanular form, with 5 short revolute 
lobes, it is about an inch long, of a bluish violet colour, 
pubescent and apparently not marked with the radiate 
nervures so conspicuous in Nolana and Sorema. "The con- 
tracted portion of the tube of the corolla is pubescent within, 
whence the stamens arise, the filaments are dilated, tapering 
upwards, smooth, and unequal, the anthers are oval, bluish, 
and included within the mouth : the style is of equal length. 
The disc has a 10-lobed border, and supports 8 to 12 ovaria. 
The drupes are fleshy, and vary in size. I found in one case 
five nuts, each 3-celled, and seven 1-celled—in all twelve 
nuts with 22 cells: in another instance, I observed three 
nuts each 4-celled, two 3-celled, one 2-celled, and two 
l-celled, in all eight nuts with 22 cells. The whole plant 
is densely covered with short greyish tomentum, the hairs of 
which, when magnified, appear sometimes articulate, but 
most generally stellate and stipitate, a form of pubescence 
peculiar to this genus. I confess, however, that I feel some 
hesitation in referring this plant here, as its corolla more 
nearly approaches that of Sorema and Alona in size and 
colour, but in its general aspect, peculiar habit, the size and 
shape of its leaves densely covered with remarkable tomen- 
tum, as wellas in the form of its nuts, it greatly resembles 
the two preceding species. 
GRABOWSKYA. 
This genus was founded by Prof. Schlechtendahl (Linn. 7. 
72) upon the Ehretia halimifolia of L'Heretier (Stirp. p. 45. 
tab. 23). By Linnæus and succeeding Botanists, it was as- 
signed to Lycium, without doubt on account of the similarity 
of its flowers and habit to that genus. Schlechtendahl, for 
the same reasons, preserved his new genus Grabowskya 
among Solanacee, but Nees von Esenbeck restored it to 
Ehreliacee, because of its unilocular 4-celled. ovarium, be-
