being abundant in tropical continental America, belong to 
Phragnipedium. 
The leaves in both of these genera are strap-shaped, thick, fleshy, 
and narrow. This character serves at once to distinguish them 
from the two other genera, Cypripedium and Selenipedinm, com- 
pleting the group of four already referred to. In these latter the 
leaves are broad, thin, and many-nerved, a character by which 
they may be readily separated from Paphiopedilum and Phragmi- 
pedium. In this latter group of two the perianth falls off early, 
while in Cypripedium and Selenipedium the perianth is persistent, 
remaining in a withered condition upon the developing seed-ves- 
sels. To Cypripedium belong all the plants of our woods and 
The remaining genus, Selenipedium, is a native of acechern 
South America. It is very rare in cultivation, and is repre- 
sented by only three species. 
The interesting forms in this collection are so numerous that 
it would be impossible to designate them all. Some of those 
which have flowered recently or are now in flower are referred 
to below. 
In Poplipedion in insigne, one of the early introductions from 
the Himalayan region, we have a charming orchid, quite varia- 
ble in its ane scheme, the various color-forms apparently being 
of local distribution. Mr. Ames has brought together a choice 
collection of these Hari among them eae Dorothy, Chan- 
tinii, Laura Kimball, Sanderianum, Harefield Hall, and Sande- 
The last, cane , is the most ee of them all, the 
whole flower being of a beautiful ae ice with the ex- 
ception of the upper part of the dorsal sepal, which is a pure 
white, with a few minute brown dots at its base. This has been 
onjunction with another Himalayan orchid, de ede 
Pitcherianum, in the production of an exquisite little hybri 
eral plants of which came from Mr. Ames labeled: “ Cas 
x tsigne Sanderae.” These vary considerably in shades and 
markings, but all of them are free-flowering and good growers, 
the flowers being large and of clear color. One of these plants is 
especially noteworthy, having a large, pure white dorsal sepal,
