DIADELPHIA. OCTANDRIA, 
cumbent, apetalous. P. rubella. Willd. Han. In the Pine 
forests of Lake Michigan. Ons. Perennial, and subde- 
cumbent; flowers reddish. Allied to P. Senega. Myr. 
Pursh’s plant appears to differ considerably from the one 
here described, but 1 am persuaded it is the same, from 
a food specimen which J] have seen in the possession of 
Z. Collins, Esq. agreeing with the Michigan plant. 
9. lutea, Stem branching, lower leaves spathulate, upper 
lanceolate; spike subcapitate, obtuse; wings of the calix el- 
‘liptic, acute, bractes shorter than the flowers. Naz. New 
Jersey to Florida. 10. viridescens. Stem simple or none; 
radical leaves spathulate, often retuse, cauline ovate; 
spike ovate; wings of the calix acuminate; braces nearly 
as long as the sessile fowers. Han..In the Pine forests 
_of Carolina and Georgia. Oss. Autumnal and winter 
spikes squarrose and stemless, sessile amidst the radical 
leaves; flowers always green with a tinge of yellow. It 
appears to be very nearly allied to the preceding, but 
what resemblance it bears to P. incarnata is more than I 
can imagine, and Mr. Pursh’s giving it a habitat in Penn- 
sylvania almost proves that he had never seen our plant.
