FIELD NOTEvS OF WESTERN BOTANY 317 



others the fullest complement of pistils but only a stamen or 

 two, or in some I think not one. I must here state, in passing, 

 that having a desire to study these New York plants another 

 season, I went out to Rock Creek Park, sought there in the deep 

 woods, a cool moist northward slope, such as this species likes, 

 and planted them with all care, and at a place to which I believed 

 I should easily find my way at any time; but I have sought it 

 since in vain. The species is entirely foreign to the flora of this 

 region. Supposing that colony w^hich I planted, the locality of 

 which I seem to have lost, survives, the possible future discoverer 

 of it will stand admonished not to take the species to be indigenous 

 there. 



In the middle of May of this year 191 4, in western Wisconsin, 

 I had an opportunity of seeing and collecting this species in fruit. 

 The achenes had reached their full size and were very nearly 

 mature; and now I noticed, while selecting good fruiting spec- 

 imens, that such as had no fruit bore among their leaves a full 

 complement of mere naked peduncles, which, however, had in 

 no degree withered, but were still alive and fresh despite their 

 infertility and their nudity, by which latter term I mean that 

 not only what we have been taught to call the flower had fallen, 

 but even also the so-called involucral leaves. I seemed to have 

 before me evidence not only perfect dioecism in this hepatica, but 

 also that what we have been taught to regard as the involucre 

 in these plants, is really a calyx, and that the supposed sepals 

 are a corolla. The consideration of such a fact as this, and one 

 so strongly suggestive of a possible revolution in our philosophy 

 of the hepatica flower, irust lead to its further observation. The 

 living but sterile peduncles seemed to end as abruptly as if there 

 had been a joint where the "involucre" had broken away. The 

 precise locality at which these observations were made is on a 

 steep rocky but densely wooded slope above the Wisconsin River, 

 at Woodman, Wisconsin.
