GENETICS OF THE ROSE.*
*A paper contributed to the international Rose Conference by Major C. C. Hurst.

Platyrhodon microphylla, from China and Japan, the so-called Chestnut Rose with cup-shaped fruits covered with fleshy spines, seems more promising in its fertility since I have succeeded in raising the second generation of a cross with Rosa rugosa. The results, however, although extremely interesting from the scientific point of view, are not very promising horticulturally, since the grandparent R. rugosa has been reproduced in facsimile several times, while the others resemble the parent hybrid with strange mutational variations.
