132 THE ORCHID REVIEW. [May, 1909. 
differing from the preceding in its evergreen habit, conduplicate 
leaves, and deciduous perianth, and from all the others in having an 
imbricate (not valvate) perianth. The two first are Tropical American, 
and have the ovary of Apostasiez, the third is widely diffused through the 
North temperate zone, and the last extends from North India and South 
China through Malaya to New Guinea. The tribe is in a transition state, 
for the two latter genera have the ovary of Monandre. Selenipedilum is 
probably not in cultivation, the species so-called in gardens really belonging 
to Phragmopedilum. 
We now come to the great suborder Monandre, characterised by the 
possession of a single stamen—the median one of the outer staminal whorl. 
The simple pollen grains of the Diandre are now left behind, and we find 
them cohering in fours (tetrads), or the contents of each pollen sac cohering 
in masses, called the pollinia. Correlated with this character we find that 
the third stigmatic lobe (the median one) is modified into a totally new 
organ, the rostellum, whose function it is to secrete a viscus by which the 
pollinia are attached to the body of the fertilising insect, and to prevent 
them from falling on to the stigma of the same flower. The stamens and 
pistils are confluent into a central column, and the two lateral stamens of 
the inner whorl are only present as staminodes, which usually take the form 
of a pair of wings or teeth, situated at the sides of the stigma, while those 
of the outer whorl are confluent with the median petal, forming the lip and 
its crests. It is believed that the third stamen of the inner whorl is also 
frequently represented in the crests of the lip. These characters may be 
regarded as common to the suborder, but there are other phases of 
complexity which will be mentioned under the different groups in which 
they are found. These must be left for a later paper.

AN ANOMALOUS CYPRIPEDIUM CAPSULE. 
Last year, in the collection of G. Shorland Ball, Esq., Under Fell, Burton, 
Westmoreland, on a plant of Cypripedium x Eve, the flower of which had 
been fertilised, I noticed on the base of the seed capsule, a small leaf, which 
kept growing, and after a time made a second leaf. I tied some moss on 
the flower stem underneath the leaf; and in about a month a young root 
was pushing through the moss. After sowing the seed I placed the lower 
portion of the seed capsule, with the young growth attached, in a pot with 
a little loam and moss, and now it is showing another root, also a third leaf, 
I should be glad to know ifany of your readers have had a similar experience.
