1908] Deane,— Trillium undulatum 23 
On another sheet in the Gray Herbarium I find the third unre- 
corded instance of teratology in the species in question. The speci- 
men was collected in Fitzwilliam, New Hampshire, in May, 1891, by 
Miss K. L. Kimball. In this plant the leaves, sepals, petals, and styles 
are in fours. There are seven stamens but there was probably an 
additional one originally. - 
In the Plant World for April, 1903, p. 89, Mr. E. L. Morris states 
that abnormalities in Trillium undulatum “have been noted by the 
Macouns, father and son." In regard to this Mr. J. M. Macoun 
writes me that "neither my father nor I have ever noted teratology in 
T. undulatum," so there must have been some misunderstanding in 
regard to the matter. 
Two other records deserve mention. In Кнорока for February, 
1905, p. 40, Mr. Frederick S. Beattie says, "I collected a specimen 
of this [T. undulatum] on May 21 in Gloucester which possessed 
two stems proceeding from the same corm. Furthermore, on the 
flower of one of the two twin-stems, one of the sepals was enlarged 
to a length five-sixths that of the ordinary leaves, the shape of this 
sepal also approximating that of a leaf, rather than that of a sepal." 
In the American Journal of Science and Arts, 3d serles, vol. XV, 
February, 1878, p. 153, Dr. Asa Gray says, “ Pastor Wibbe also sends 
a polymerous state of Trillium erythrocarpum. Something of the kind 
not rarely occurs in Trillium. This plant, which has been constant 
since discovered five vears ago, has all the parts from leaves to carpels 
regularly increased (in the leaves apparently by chorisis) from three to 
nine, except that the stamens hardly keep up to double the number 
of the petals.” Doubtless the very specimen referred to is the one that 
I find in the Gray Herbarium. Itis labelled in Dr. Gray's handwrit- 
ing, “Т. erythrocarpum — 8-merous — Lily Marsh near Oswego, 
N. Y.— J. Н. Wibbe — 1877." A careful examination of the plant, 
however, shows a discrepancy between the number of parts and the 
description as quoted above, the statement on the label being more 
nearly correct." There are eight sepals and eight petals and all these 
are normal with the exception of one sepal which has a white petaloid 
growth on one side. There are at least 20 stamens and on the side of 
the pistil that is visible there are six carpellary divisions of the ovary. 
The leaves are in a whorl at the top of the stem and are seven in num- 
ber, but the S-merous character is shown by the fact that one of the 
leaves is double. It has two midribs and is forked at the tip, the sinus 
between the two apices being half an inch deep.
