Eastern Tibet.

Many and interesting as are the specimens of Primulacee 
that have become known in recent years from Yunnan and 
Tibet, the forms which I describe below will serve to indicate that 
the area is yet far from being exhausted of novelties. Of the 
thirty-nine species of Primula in my collection enumerated 
here, fifteen are new ; of seven species of Androsace, one is new; 
and of thirteen species of Lystmachia, three are new. Many of 
them are of great beauty and should be welcome additions to 
the hardy plants of gardens of this country, and I am glad to 
say that seedlings of several of the best of them have been 
raised and will probably be within reach of horticulturists in 
the course of this year (1908). 
The most interesting amongst the known species of the 
collection are P. vincaefiora, P. Delavayi, and P. Franchetzt, 
three of the four species at present constituting the remark- 
able section Omphalogramma, which takes its name from the 
oval and flattened form of the seed. Certainly no one with 
knowledge of the form of seed usually met with in Primula 
would suppose at first sight that the seed belonged to a species 
of that genus. Franchet, who described the bulk of the col- 
lections made by Pére Delavay in the region from which the 
above came, was so struck by their singular appearance that he
