ocrnotes:Potamogeton flabeltatus, Bab, A splendid scries of this distributed by Mr. Alfred Fryer, in sets of three, viz. :--839. Drain by For trey Hall Farm, Welches Dam, 12th Aug., 1887 : 840. Same locality, 22nd Aug,, 1888; S76. The New Bedford River, 15th July, 1887; all in Cambridgeshire, Co. 29. " The broader leaved forms from the Ouse and the New Bedford River agree well with Professor Babington:s typical plant; the finer leaved forms from Welches Dam are towards the P. "seoparius" of British authors. The Professor has kindly examined all my gatherings for some seasons past, and considers all the plants now sent as belonging to his P. flabeltatus. I have carefully watched these forms for four years, and have satisfied myself by the habit of growth and foliage, as well as by the fruit, that these plants cannot come under P. pectinatus, as at present restricted by Professor Babington, Occasionally, but not constantly, all these flabeltatus forms produce broad flat leaves at all scasofis of the year in our fenland waters; I think such leaves will only be found constantly in situations where the plant is unable to perfect its fruit. In cultivation some shoots from the same rootstock produce them, others do not, and they vary in abundance from season to season. Hence we ought not to attach too much importance to their presence in distinguishing between ftabellatus and pectinatus, but look chiefly to the differences between the fruit, on which Professor Babington founded his species."--Alfred Fryer.
