2. N. amphibium (R. Br.) ; pods elliptical much shorter than 
their pedicels, /. oblong- lanceolate attenuated at both ends sessile

R. 4363. ct. /3. y. — Fl. yellow. Submersed 1. pectinate-pin- 
natifid. Pod erecto-patent. Should not this plant be referred

Nasturtia by its very short pods with remarkably convex valves ; 
and that is the only character which separates Armoracia from 
Nasturtium. Its habit is that of A. rusticana. Watery places.
