of the pod. The color of the corolla-blades is a sea-foam yellow 
rather than white, and the eye is of Tyrian rose, which is a rather 
intense shade of red. ‘There are further distinguishing characters 
in the small stigmatic lobes, which here are scarcely expanded 
ends of the divisions, and in the light yellow or almost white 
color of the pollen. There is also a considerable difference in 
the length of the various stamens, those at the base of the 
stamen-ring having shorter filaments, and there is considerable 
red in stems and foliage quite as in Races 6 and 7 of Hibiscus 
Moscheutos described above. 
Some lines of descent have bred remarkably true to the above 
mentioned characters, but others have shown considerable varia- 
tion in the color of the flowers, the tendency seeming to be 
toward decreased intensity of the eye area and to the develop- 
ment of pale diffuse colors in the blade. There has also been a 
pronounced tendency toward dwarfness, as has been discussed 
by the writer (Stout, 1915). 
HYBRIDS BETWEEN H. oculiroseus AND H. Moscheutos. 
Britton and Brown (1913) recognize a hybrid between these 
two species and note that it is intermediate in flower character. 
The writer has produced these hybrids in pedigreed cultures 
from seed obtained by controlled pollinations. The F; hybrids 
between the typical oculiroseus and Moscheutos (Races 1, 2 and 3) 
have flowers with an eye of less intense color than has H. oculiros- 
eus combined with a pale pink blade. The stigmas, stamens 
and pod characters are rather intermediate. It may be noted 
that the beautifully colored illustration given in Flore des Serres, 
vol. 12, Plates 1233-1234, 1857, and there identified as Hibiscus 
Moscheutos is an exact representation of the F; hybrids of this 
cross. The F, generation breaks up into almost every conceiv- 
able grade of variation in regard’to eye and blade colorations 
and to characteristics of stigma, stamens and pods. 
F, plants of the cross between H. oculiroseus and H. Moscheutos, 
Race 5, are at first sight quite readily taken for H. oculiroseus, 
but a more careful examination shows that the eye is paler and 
the blades are dead white instead of pale sea-foam yellow. 
Plants of the F; generation of this cross have not yet bloomed.
