Nos. 2 and 4 show the effect of the father. 
It is equally important to secure fruits of the Pomelo type, which have 
the easily removable skin and easily separable segments of the Mandarin 
type of Orange, and to secure improvements in this direction many 
hybrids of the Tangerine and Pomelo have been made. The resulting 
seedlings, as in the case of the Tangerine Orange hybrids, mainly resemble 
the mother parent ; but the Pomelo foliage being more markedly different 
from the Tangerine than that of the Orange, the differences are much 
plainer. Of 116 hybrids of the Pomelo crossed with pollen of Tan- 
gerine 111 had plainly the broad-winged petioles and robust foliage of the 
female parent, while only five showed the foliage characters of the Tan- 
gerine or male parent. No reciprocal hybrids were made in this case.

Change of Quality—Among the varieties of citrous fruits now culti- 
vated are several fairly desirable fruits, quite distinct in their characters, 
which from their appearance seem to be hybrids of the Orange 
(C. awrantium sinensis) and Pomelo (C. decumana). The variety known 
as the Aurantium-Pomelo is so called because of its supposed hybrid 
nature. A fairly well-known Jamaican Pear-shaped Pomelo of small 
size, with orange-yellow skin and Pomelo-like pulp, seems also to bea 
hybrid between these two species. We have made quite a number of 
crosses of these species, hoping to secure fruits markedly different from 
those now in cultivation, and which will prove valuable commercial 
varieties. Of 126 hybrids of the Pomelo with pollen of the Orange 106 
resembled the mother parent and twenty the male parent.
