1911] Deane,— Teratology in Trillium ovatum Pursh 191 
The shape of the petals are as follows: 
Ist whorl, broadly ovate. 
2d [11 [71 [11 
3d ^" ' first two slightly ovate, third oblong. 
4th “ first ovate, second and third obovate. 
5th “ broadly ovate. 
6th “ first ovate, second and third oblong. 
All the petals are obtuse. There are no stamens or pistil. An 
interesting accompaniment to the multiplication of petals is, as 
before related, in the color, the white turning to pink and white, instead 
of purple. The general resemblance of the flower to that of our 
beautiful sweet-scented Water Lily, Castalia odorata (Ait.) Wood- 
ville & Wood, with its many petals, is well shown in the accompany- 
ing illustration kindly drawn by Mr. F. Schuyler Mathews. A form 
of this Water Lily growing mainly near the coast has petals varying 
from white and pink to pink-red in color. 
Turning to the literature dealing with the multiplication of petals 
in Trillium I find that Prof. F. M. Andrews says in The Plant World 
for May, 1906, page 101, concerning some plants found near Bloom- 
ington, Indiana, “In Trillium recurvatum the number of these leaves 
[floral leaves or petals] in the flowers without reproductive organs was 
twenty-three, and in Trillium sessile fourteen.” A specimen of 7. 
recurvatum with twenty floral leaves or petals is figured on page 103. 
In the Asa Gray Bulletin for February, 1898, pages 18-20, Mrs. 
W. A. Kellerman tells a most interesting story of a double Trillium 
grandiflorum. The plant was found in the woods of Jefferson County, 
Ohio. It had thrived, after being transplanted, for ten years, always 
producing a double flower, when Mrs. Kellerman secured three flowers 
from the plant. Two she mounted in diagrammatic form, one show- 
ing nine, and the other thirteen whorls of petals. The latter is figured 
on page 20. 
The late Prof. William R. Dudley in The Cayuga Flora, 1886, page 
99, under Trillium grandiflorum Salisb. says, * Double-flowered speci- 
mens from Woodwardia Swamp Woods, have about 14 parts to the 
perianth." Instances might be multiplied, but enough have been 
given to show that this phase of teratology in Trillium is well known 
in a number of species, but, so far as I have learned, it has not been 
previously recorded for the northwestern Trillium ovatum.
