great profusion through the whole season. It is raised 
from cuttings, the same as the Verbena, and like that 
plant, must be housed during the winter. All the Cu- 
pheas, with which I am acquainted, are tender; most suc- 
ceed well as annuals, of which I have grown a number of 
species, but believe, those who have seen the one described 
above, and compare it with any other sorts introduced, 
will be satisfied with that alone. C. Zimpanii is a pro- 
fuse growing, spreading plant, with dark-purple flowers, 
which wither soon under a hot sun, and, although very 
pretty, not worth the trouble of raising.

CYPRIPEDIUM.—Lavy's Surrer. 
[From Greek words, Venus, and a slipper, an allusion to the elegant slipper- 
like form of the labellum.] 
Cypripédium acatile, differs from the other species in 
having no stem leaves. The leaves are two, springing 
from the root, large, oval-lanceolate, plaited, and downy. 
This is the most common species, sometimes called Two- 
leaved Lady’s Slipper, or Whip-poor-will’s Shoe. It is 
found in rich and somewhat shady woods. This singular 
flower has its sepals and petals spreading, green with a pur- 
ple tinge, except the petal which forms the lip, or purple 
inflated bag, which is veined, villous, and longer than the 
other parts of the flower. The flower stems are about one 
foot high, bearing one solitary flower, in May and June. 
C. parvifl6rum.—Y ellow Lady’s Slipper.—Thisis another 
beautiful indigenous species, not very common about Bos- 
ton, but found in some localities in this State, New Hamp- 
shire and Vermont. The lip of this flower is oblong oval; 
yellow, dotted inside; its aperture roundish with an in- 
flexed margin; stem erect; leaves alternate, clasping, 
oval, nerved, downy; blooms in June.
