1. Peltandra undulata Raf. 1819. Petiols 
equal to leaves striate dimidiate, leaves sa- 
gittate nndulate oblong cuspidate lobes oblong 
obtuse, scape striate terete punctate of black, 
spatha subequal, base inflate, split in the mid- 
dle, margin undulate, end narrow involute. In 
the Alleghany and Mattawan mts, also in New 
Jersey &c, it flowers in June, spathe lucid 
blackish green, margin yellow, spadix white, 
young petiols glandular, leaves 5 to 10 inches 
long. This was the type of my Peltandra 
having 3 to 5 seeds. It is hard to say which

Virginicum of Clayton and Linneus. 
2. Peltandra canadensis Raf, Arum sa- 
gittatum foliis elongatis, Charlevoix pi. canad. 
fig. 81. Arum Virginicum of many botanists, 
Lecontea virg. Torrey. Renselaria virg. Beck. 
Petiols elongate terete not punctate, leaves 
oblong flat hastate cordate, cuspidate, lobes ob- 
tuse : scapes several subcarinate, spatha lan- 
ceolate involute, margin undulate— In Canada, 
New York, New England and Pennsylvania. 
This is the type of Renselaria having only 1 
or 2 ripe seeds, easily known by flat leaves se- 
mipedal, long petiols not dimidiate & c. 
3. Peltandra latifolia Raf. Petiols short 
dimidiate flat above, leaves broad triangular 
sagittate, undulate cuspidate, lobes divaricate 
obtuse ; scapes several terete incurved, berries 
often one seeded — In the waters of marshes, 
ponds, creeks, in south New Jersey and Dela- 
ware, leaves often one foot long and broad : not 
rare there, but seldom found in flowers. It be- 
long to subgenus Renselaria, but is quite dis-
