SYNOPSIS OF THE GENUS LONICERA. 203 
species of the subsection Ochranthae, especially L. Ru- 
prechtiana and L. Morrowii, to hybridize with L. Tata- 
rica that it is almost impossible to raise them true from 
seed if ZL. Tatarica grows near the mother plant; conse- 
quently the typical species have become comparatively rare 
in gardens, while the hybrids are often met with. These 
hybrids fruit as profusely as the species and seedlings raised 
from their seeds show almost invariably a reversion to 
L. Tatarica; probably they are usually fertilized by the 
pollen of that species. 
I. Subgen. CHAMAECERASUS.

L. propingua, Zabel, l. c. 
L. propinqua superalpigena, Zabel, l. c. 
Originated in the botanic garden at Muenden! and is 
sometimes cultivated (Arnold Arboretum, etc.). 
A very interesting hybrid showing in its two forms, one 
more resembling the ZL. alpigena, the other more the L. 
Ledebourii, clearly its origin by its curiously mixed charac- 
ters.
