 of this region, informed me he had seen it growing native in the above locality. 



CLASS XVIII. GYNANDRIA. 



304. ORCHIS. Nutt. Gen. 706. 

 [A whimsical Greek name; and more tolerable in Greek than English.] 



L'oR. ringcnt, upper leaflet vaulted. Lip dilated, base spurred beneath. Pollinia 2, terminal, adnate.

Oba. This species grows in the alluvial district towards Wilmington, Del.— also in the Great Valley, ani 

 on the farm of Mr. John D. Steele, in West-Bradford: but has not yet been found in this immediaVe 

 vicinity.

Fl. Latter end of June. Fr- mat. 



Hab. Moist woodlands: Jesse Good's: rare. 1 to2 feethigh: flowers greenish white. 



Obs The O. psycodes, of Pur.ih, Willdenow, &c. is probably distinct from this; as they speak of the 

 flowers being yelloio. In other respects, however, it seems to approach it.

Fl. Beginning of June. Fr. mot. 



Hab. Moist thickets: onmyiarm: rare. 12 to 18 inches high: flowers 3'e;iowish green. 



Obs. The existence of this rare species seems to have been doubted by our later wviters on American 

 plants; as it is not noticed, either by Muhlenber.;-. Nuttall, or Elliott. Even Pursh himself did not see it. 

 But the description given in his Supplement, p. 743, tits my plant precisely, so f.ir as it goes; and 1 am fur- 

 ilier confirmed, as to the species, by Dr. Torrey, to whom 1 sent a specimen- The stem is angular, flexu- 

 ose, leafy; leaves 3, or 4, oblong-lanceolate,"acute, 1 to 2 inches wir'r. rvnd 4 to 6 inches long; bractes 

 lanceolate, twice as long a« the flowers; root fasciculate.
