GYNANDRIA, MONOGYNIA. 143 
Long-leaved Malaxis. 
From three to seven inches high. Leaves very long, always 
longer than the scape and spikes, when the plant is mature, 
i Root roundish. Flowers one-third the size of those in No. 1, 
and a little larger than those of No. 3, of a yellowish-green 
colour; lateral petals yellow. I first discovered this plant in 
June, 1814, in the woods north of Powelton, on the Mantua- 
road, at which time I detected only three specimens. I found 
it abundantly the next season in the same place, and have sub- 
sequently met with it in the shady woods bordering the Schuyl- 
kill. Mr. Nuttall has found it this year on the Wissahickon, 
near LangstrotlPs mills, growing with No. 1. Perennial. June. 
3. M. one leaf, ovate, amplexicaiile ; scape five- opiuogiossoi- 
angular; lip bifid at the apex. — Willd,
