Popu.ar aNp GeocrapuicaL- Notice. This addition to the ge- 
nus Philibertia is a native of the district between Buenos Ayres and 
Tucuman, where it was discovered by Mr. Tweedie, who sent it to his 
friends in this country, under the name of “Green-flowering Ascle- 
pias of Saint Kathrens.” Its flowers serve well to exhibit the curious 
structure of asclepiadaceous plants, for our general knowledge of which 
we are indebted to Mr. Robert Brown (Memoirs of Wernerian Society, 
Vol. I, p. 19.) whose acumen has also revealed to us the singular mode 
of fecundation of these plants. (Trans. of Linnean Society, Vol. XVI. 
INTRODUCTION; WHERE GROWN; CULTURE. Seeds of the Philiber- 
tia gracilis, were sent by Mr. Tweedie, in the later part of the year 
1835, to various British cultivators. A portion of these were received 
by Mr. Nevin, of Glasnevin Garden, Dublin, who kindly supplied us 
with a drawing from one of his plants, which had been trained to a 
support in the stove, where it had proved evergreen, and flowered 
from May till October. It can scarcely be doubted but that if young 
plants be turned into the open ground, in May, and trained to a wall, 
they will become very ornamental. Cuttings strike root readily, and 
asoil composed of a sandy loam and peat proves suitable to its growth. 
Derivation or THE Names.
