exceptions 60-70 specimens each, and almost all of these have 
flowered. As the types of the triple hybrids were exactly the same 
as in the first generation, no special descriptions will be necessary. 
In this table + means that a second generation of the type men- 
tioned in the heading above it has been cultivated, whereas — indi- 
cates that no culture of the type has been tried. 
A third generation of ovata was cultivated for O. nanellaX 
grandiflora. From the reciprocal cross /utea and brunnea were con- 
tinued during one generation more. I shall treat the crosses of 
O. grandiflora lorea separately, since they split off this mutant type, 
and deal first with the others. Among the special combinations 
appearing in the second generation there were three which could 
clearly and easily be distinguished, but only two of them were fre- 
quent. I shall designate them by the letters R, 7,and L. Among 
these, R was a return to the rapid production of a stem, without 
preparatory rosette of radical leaves, which is so characteristic a 
mark of O. grandiflora, but which was always dormant in the first 
generation. The plants were usually slender and small, the leaves 
broad and dark green, and they flowered one or two weeks before 
their stouter sisters. In July they reached 10-30 cm. more in height 
than these, but during the flowering period they were overgrown 
by them. Their flowers showed the same forms. The progeny 
of the type R was uniformly so. The type T was easily recognized 
by its truncate flower buds; these are conical in the parental 
species and in the triple hybrids. The flowers were correspondingly 
smaller. The leaves were almost like those of ovata, but strikingly 
broader in their upper half. The height and stature were also the 
same. In their progeny they repeated their characters exactly, but 
split off some specimens of the type R. Type T was remarkably 
rich in the production of pitchers. The type L combined the char- 
acters of the hybrid called Jutea with the slender stature, rich 
branching, and thin flower buds of O. grandiflora. It produced 
some specimens of R among its progeny, which was otherwise 
uniform. A continued study of these and other hybrid types of 
O. grandiflora would probably offer the material:for an analysis of 
the characters of this species. In counting my cultures of the off- 
spring of self-fertilized ovata at the beginning of the flowering period, 
I found the figures as given in table VIII.
