16 em. long. The peduncle varies from 2 to 220 mm. in length. 
The sepals may be sessile or on stems 44 mm. long, and sim- 
ilarly the stalks of the petals may reach 64 mm., the ovary 
stalks 23 mm. The stem-leaves are sometimes absent. 
From the fact that the same rootstock produces the same 
peculiar condition year after year, as has been shown by 
transplanting the specimens, it is evident that the various 
abnormal conditions are inherited and not environmentally 
produced, as has been so frequently conjectured ; though the 
type of abnormality produced by a given rootstock will per- 
haps vary within limits from year to year. It would be in- 
teresting to know what these limits of variation are for indi- 
vidual rootstocks showing different stages of the abnormality.

In Troy, Ohio, was found T. sessile L. with three stems 
arising together from rootstock. The first stem had 3 whorls 
of 3 leaves each, the lower 2 crowded together, 4 petals, no 
sepals, 5 stamens, 3 styles and stigmas, and ovary 6-angled. 
The second stem had 2 whorls of 3 leaves each, no sepals, 6 
petals, 7 stamens, 4 styles and stigmas, and 8-angled ovary. 
The third stem had leaves as in the second, but 3 sepals, 6 
petals, 9 stamens, 2 styles and stigmas.

Near Washington, D. C., was found a plant of T. sessile L. 
bearing two single leaves with very long petioles, direct from 
the rootstock.

This figure is a plant of T. grandiflorum var. variegatum 
from Hamilton, Ont. Two specimens from Moose Head Lake, 
Maine, 1898 (Aug.), collected by С. B. Grant, “һауе the 
simple leaves long-petioled from the rootstock." Probably 
these free, single, long-petioled leaves are an extreme case
