denticulate, blade narrowing gradually to a very short petiole, 
midribs and petioles bright red dorsally and ventrally; lower- 
most bracts 17 mm. in width by 9 em. in length, upper bracts 
11 mm. wide by 58 mm. in length. .The buds most resemble 
those of (E. grandiflora, being nearly devoid of long hairs, slender 
and somewhat rounded, with setaceous sepal tips and some red 
on the sepals; length of petals 32 mm., hypanthium 43 mm., 
sepal tips 9 mm., ovary 10 mm. 
In 1912 three families of Е, offspring, numbering in all 236 
plants, were grown from the plant just described. АП three 
families agreed in containing several types exhibiting a remark- 
able degree of variability. 
An attempt was made to place the plants in five classes, but 
the categories overlapped and made classification for the most 
part impossible. Тһе majority of the plants resembled the 
parent individual in their main features but they varied enor- 
mously in width of leaf from broad (21 mm.) to very narrow 
(8-6.5 mm.). These conditions were connected by interme- 
diates, and, moreover, there were considerable variations within 
the individual, one braneh with very narrow leaves being found 
on a plant with broad leaves. In addition to these variants, 
the three families contained 35 dwarfs, or 14.8 per cent, and 
the latter varied in leaf-width in the same remarkable manner. 
The dwarfs agreed only in having short internodes. Two of 
them are shown in pl. 21 figs. 13, 14, the former having narrow 
leaves and extremely short internodes, the leaves of the latter 
being quite linear. Тһе plant would never be taken for an 
cenothera. 
Тһе advent of a large percentage of dwarfs in this family is 
similar to their occurrence in other G7. grandiflora races from 
that loeality (see Gates, '14, p. 246). Тһе precise manner in 
which this capacity for producing dwarfs is inherited, is a diffi- 
cult question which need not be considered here, particularly 
as it has been discussed elsewhere (Gates, '14). 
Plate 22 fig. 15 represents one of the Lamarckiana-like 
rosettes from this source, grown in 1909. Others approached 
de Vries’s race more closely, to the point of identity. Plate 22 
figs. 18, 19 represent selected rosette-leaves taken from this cul- 
ture to show the range of types exhibited. Such leaves as the
