trary to the results with the М. flavo-virens 9 ХМ. capensis 
var. zanzibariensis f. rosea 8 cross, no doubt being derived 
from М. ovalifolia, as the pink М. са ай Лога is apparently 
fixed. It suggests that N. ovalifolia is derived from a blue 
parent. 
There are two separate leaf characters which warrant a 
segregation: (1) a distinct marmoration on the upper sur-

plainly evident in the seedling leaves only of №. castaluflora 
and in both seedling and developed leaves of N. ovalifolia; 
(2) the dark green color of the upper surface and the light 
green densely spotted with purplish blue on the under side, 
this being the dominant leaf character. The former is char- 
acterized below as a horticultural variety marmorata. 
Some parental characters are plainly evident, and others 
are exaggerated; as, for instance, the number of petals and 
stamens are intermediate, showing an increase over the pis- 
tillate parent and a decrease from that of the staminate side. 
The outer petals are hooded and show the influence of N. 
castaluflora, and an improvement over either parent is evi- 
dent in the size of the flower. The prominent markings on
