MORE TERATOLOGICAL FORMS OF TRILLIUM 
UNDULATUM. 
WALTER DEANE. 
I HAVE recently received, through the kindness of Mr. Edwin 
DeMeritte, some more examples of teratology in our common Painted 
Trillium (Trillium undulatum Willd.) from Holderness, New Hamp- 
shire. A specimen of this species, illustrating this curious modifica- 
tion, was collected in August, 1907, by Mr. DeMeritte, in the same 
locality, and it formed the basis of an article, which I published some 
months ago (Внорова, x. 21-24). The locality, as I described 
before, is on the shore of Squam Lake “‘in the leaf-mould and scanty 
soil on a rocky ridge" near the water. 
It was in early July that Mr. DeMeritte visited and collected the 
plant for the second time. Оп the very same spot as before, and one 
stem at least evidently from the same rootstock as the plant of 1907, 
there were five stalks growing in a close cluster, three of them with 
three whorls of three leaves each, one with two whorls of three leaves
