| notes: | botanical exchange club of the british isles (see report for 1893) copy from report? Potamogeton salicifolius, Wolf. In the Wye,Carey,Herefordshire, May and July,1893. This is the first year i have seen the plant since about 1877, although i have searched a good deal. At Carey it grew in three spots, in a range of half a mile: two in shallow water with a gravel bottom; one in deep water, on mud. Rev. E. F. Linton, to whom I shewed it, was fortunate enough to find one or two immature fruits. --Augustin Ley. "The former specimens gathered in July, 1877, and determined by Prof. Babington as the salicifolius of Wolfgang (although he then supposed this to be the same as Lonchites, Tuckerman), along with the 1893 specimens, seem to me to represent the plant of Wolfgang, Besser, and Gorski (P. Lithuanicus). Dr. Yiselius contends with some reason, that they are, along with his P. Upsaliensis, forms of P.decipiens, Nolte, the hybrid commonly accepted as lucens x perfoliatus. Perhaps such a cross with a long-leaved form of lucens, and the same of perfoliatus, might produce such a leaved plant as salicifolius. One can see with some reason the hybridity of the usual form of decipiens as about halfway, while others decidedly show a more lucens-like type. But Wolfgang's plant shows a peduncle and spike that can hardly be referred to either supposed parent. It may be that the original plant was a product of P. macrophyllus, Wolf., and some perfoliatus form but so faras i know no macrophyllus (longifolius, Gay.) form grows at the Herefordshire station. While not denying that this plant may be a hybrid, I cannot satisfy myself that it can be placed as a decipens state merely, much less differences are accepted as specific now, than these show in a series. On the other hand some of the Hants specimens of decipiens have a decided look of some of the forms P.Upsaliensis, Tis., but the difference has yet to be brigged over, I consider" --A.Bennett. |
