|Other name:||Naiadaceae: Potamogeton interruptus Kit.|
|Filed in taxon folder:||Potamogeton pectinatus L. ("Fennel Pondweed")|
|Collected by:||Mr Job Edward Lousley|
|Locality:||Great Britain, VC14 East Sussex, Cuckmere Haven, TV59, Brackish pool near Cuckmere Haven, East Sussex|
|Institution:||South London Botanical Institute (SLBI)|
|notes:||Ref B.2. The correct citation for these fine examples is P.pectinatus L.var diffusus Hagstr.f.interruptus (Kit) Asch. This plant was originally described as a species by P.Kitaibel in Schultes, Osterr. Fl. 1814, 328. Babington (Man.ed.3. 1851, 343) still regarded it as such and named it P.flabellatus. In 1864, however, Ascherson (Fl.Prov.Brand.1864, 666) reduced it to a variety P.pectinatus var.interruptus (Kit.) Asch., and it has rightly been regarded as a form of P.pectinatus by German and Swedish authorities since that date. Dr Hagstrom's masterly treatment of the innumerable forms of P.pectinatus shows conclusively that all these are included under one or other of his 2 varieties - ungulatus and diffusus. Most British forms belong to the later. In Mr. Lousley's sheet the very important wider lower leaves are admirably displayed, and the plant amply justifies its label - W.H.Pearsall.|
