There can be no doubt that, although using the name R. maritima in 
the sense of R. rostellata Koch (not of R. spiralis Dumort), Hagstróm 
had the plant which is common, especially in Atlantic waters, in North 
America. His description clearly indicates this: “The European 
forms of R. maritima usually have rather short peduncles. A form 
from Asia gathered by Ove Poulsen at Buchara, in a saline pond, in 
1898 (12,183), however, has somewhat longer peduncles (3-6 cm. or 
more). We propose to name it var.longipes. In the United States 
of America this variety seems to be the commonest Ruppia. It 
appears in two forms: one with more prominent, thin beak, forma 
aculeata n. f., belonging chiefly, as I think, to the eastern States, and 
the other ‘with an almost sessile stigma’ (Rydberg, l. c.), spreading 
westward: forma pectinata (Rydb., as sp.)." Of forma pectinata 
we have little knowledge except the specimens referred to under 
R. maritima, var. obliqua. Our common plant with peduncles some- 
times reaching a length of 3 dm. is Hagstróm's forma aculeata. The 
following from the numerous specimens may be cited. NEWFOUND-
