The results obtained in pedigreed cultures indicate that various 
races exist within the species of H. Moscheutos and that hybridiza- 
tion among these and H. oculiroseus will result in increased 
variability. 
There is considerable literature (no attempt will be made here 
to summarize the literature) which indicates that there is more 
or less marked geographic limitations or even isolation of various 
races and that other races than those here mentioned may exist. 
Thus the variability may be quite different at various stations 
throughout the range. 
Very little is known regarding the range of Hibiscus oculiroseus. 
In some localities plants resembling this species seem to pre- 
dominate. Rev. J. P. Otis (personal correspondence) finds this 
to be the case near Marshallton, Delaware. However, flowers 
of nine plants which he sent to the writer showed that none of 
these conformed to the type of the species: the eye was much 
paler and the corolla-blades were either of pinkish tinge or were 
white instead of sea-foam yellow. Although there are many 
plants somewhat resembling H. oculiroseus to be found along 
the coast southward from New York City, none that the writer 
has yet seen have agreed with the type of the species grown at 
the New York Botanical Garden. | 
With the exception of Race 7, all the races of H. Moscheutos 
thus far tested hybridize readily with H. militaris giving highly 
fertile F; progeny. The latter species is decidedly distinct from 
either H. Moscheutos or H. oculiroseus and has a range that is 
more exclusively inland. It would seem, however, that in many 
localities both H. Moscheutos and H. militaris are to be found 
and that in such regions natural hybridization may occur pro- 
ducing much variability. Dr. O. E. Jennings has informed the 
writer, in a letter, that the form of H. Moscheutos which grows 
at Presque Isle, Lake Erie, has prevailingly three-lobed leaves. 
Evidently the shape of the leaves is somewhat like that seen in 
H. militaris, a condition which has not been seen in any of the 
races of Moscheutos that the writer has seen along the coast. 
It will greatly facilitate the writer’s efforts to make a field 
survey of the rose mallows if persons who have opportunity will
