The distinguishing characters of this Genus were pointed 
out by L’Hérrrier when he figured his Exreria halimifolia 
(the Lycium boerhaviefolium) ; for he says; ‘ ad Atropam 
‘ex corolla infundibuliformi et staminibus distantibus fere 
referenda est, sed calyx vesicarius baccam recondens Phy- 
salidem rectius declarat.”’ 
ScHLEcHTENDAL upon the same plant, a native of Peru, 
established the Genus Grasowskia ; and Mr. Arnotr has _ 
added two species in the “ Linnea” above quoted, the one, 
G. obtusa, from Mendoza, at the eastern foot of the Chilian 
Andes, and our present plant, from Buenos Ayres and South 
Brazil. We have received wild specimens from Mr. 'Twes- 
pig, and seeds were sent by the same meritorious Botanist 
to Mr. Moore at the Glasnevin Botanic Garden, whence 
we were favoured with the flowering specimens in July, 
1840. Mr. Moore informs us that it requires the moderate 
heat of a stove to bring the plant into flower, and that even 
then the blossoms are produced but sparingly. These flow- 
ers are different in form and in colour from the Gr. boer- 
haviefolia figured by Dr. Liyptey at tab. 1985 of the Bot. 
Register : but the specimen there figured seems to be from 
South Brazil, and is probably the Gr. obtusa of ARNoTT. 
The true Gr. boerhaviefolia has dense corymbs of white 
flowers. The essential character of our species is the sin- 
gular inflation at the base of the segments of the calyx, 
which rises into a tooth-like form. 
Descr. Stems shrubby, rambling, twelve feet high. Branches 
terete, bearing a straight spine from the axil of many of the upper 
leaves. Leaves alternate, very broadly ovate, or almost orbicular, 
exceedingly glaucous, waved, entire, slightly attenuated at the base into 
a moderately short petiole, and having a small acumen at the point. 
Flowers axillary, fascicled, from the upper leaves, which, sometimes 
becoming abortive, the inflorescence appears terminal and subcorym- 
bose. _ Calyx-tube short, hemispherical: the limb of five, spreading, 
ovato-lanceolate segments, each with the base inflated into an evident 
tooth. Corolla hypocrateriform, greenish-white ; the tube straight, very 
hairy within, the /imé of five, ovate, veined, spreading segments. Sta- 
mens five, exserted, arising from near the middle of the corolla. Base 
of the filaments (like the inner part of the tube of the corolla) villous 
with jointed hairs. Andthers oval, yellow. Germen ovate, four-celled. 
_ Style rather longer than the stamens, white. Stigma capitate, green.
