Pleione is a small Indian and Chinese genus of Orchids 
which was established by D. Don, in 1825, and after- 
wards united with Celogyne, Lindl., though markedly 
different in habit, in its annual pseudobulbs, thin, deci- 
duous Jeaves, erect, one-flowered inflorescence and in 
floral structure. At least eleven species are known, six 
of which are natives of Northern India, and all have ap- 
peared in cultivation, and been figured in the Botanical 
Magazine. These are Pleione prxcor, D. Don (t. 4496), 
P. maculata, Lindl. (t. 4691), P. lagenaria, Lindl. 
(t. 5870), P. humilis, D. Don (t. 5674), P. reichenbachiana, 
T. Moore (t. 5753), and P. hookeriana, T. Moore (t. 6388) 
—all under the name of Celogyne. They are charming 
little plants, and are often called Indian Crocuses. Two 
of the five Chinese species have also recently been intro- 
duced, but only this one has as yet flowered. 
Pleione yunnanensis, Rolfe, was originally discovered by 
Mr. W. Hancock, F.L.S., in mountain pastures at Mengtse, 
November Ist, 1906.
