| Remarks | [unpublished passage from the Journal for this date: "In the ditch behind Peters [Path] -- (& in pools in Great Meadow) the ap.[parent] true Potamogeton hybridus in prime -- The 5th kind of Floating P.[otamogeton] seen this year -- This then I must call the Smallest Floating P.[otamogeton] with immersed capillary leaves -- stem about 1 foot long X 1/25 of an inch diameter, branching below -- Floating leaves sharp elliptic--but inclining to be broadest at base -- smaller ones lanceolate acute 5 to 7 /8 inch long x 7 to 16 /40 wide very distinctly 7 (5 omitting those next edge) nerved beneath --ap.[parently] all opposite -- …. I will call this P.[otamogeton] Hybridus for present, though the spike is not globular, nor the petioles commonly less than the leaves."] |
