A Michigan Trillium. — Five or six years ago, I found a single 

 Trillium. The petals were white with a greenish stripe through the 

 center, obovate-mucronate in outline. The plant seemed specifically 

 different from other members of this genus, but, search failing to 

 reveal any more, I considered it. for some time, as merely a curious 

 sport — a sort of bisus naturpc. The next year I found more of them, 

 and have continued to find more or less every year since. Several of 

 my friends have also met this plant in their collecting. I am now 

 inclined to think it is rather widely distributed in Michigan; and the 

 facts I have gathered concerning it seem worth recording. 



The typical form of this plant is about the size of T. grandiflorum, 

 Salisb., blossoms at the same time, and is sometimes found growing 

 with it. The leaves are broadly-ovate, acuminate-pointed, and re- 

 semble those of T. grandlflorum, but are long-petioled ; the petals are 

 large, obovate-mucronate, white with a narrow or wide green stripe; 

 the ovary is green, elongate, tapering into the styles, and round, or 

 obscurely three-sided ; the ovules are sometimes 12 in number, but 

 general!}" less, often none, or only one or two, the cavity being filled 

 by an enlarged placenta. 



I have not raised plants from the seed, nor can I say, positively, 

 whether it matures seeds. My impression is that the plant fruits 

 sparingly. 



The variations from the common form are quite remarkable. Spec- 

 imens have been found with leaves not distinguishable from those of 

 T. grandiflorum:, others, with leaves reduced to mere stubs, i-i of an 

 inch long. Sometimes two leaves of the whorl will be thus reduced, 

 and the other, of normal size and shape. Often the leaves are en- 

 tirely wanting, in which case the calyx is generally larger and per- 

 forms the function of leaves. Flowers showing all sorts of grades 

 Vietween the typical form and genuine T. grandifioruin also occur. 

 Individuals with the white petals and six-angled ovary of the latter 

 in connection with long petioled leaves have been seen; also, forms 

 with sessile leaves, six-angled ovary, and greenish, green-striped, or 

 wholly green petals; also, green-striped petals and elongate ovary — 

 not angled — along with sessile leaves. The shape of the petals va- 

 ries, and they are, indifferently, smooth or wavy. As before stated, 

 when the stem is leafless, the calyx is commonly enlarged to take the
