GooDYERA. ORCHIDACEiE. 285 



Rhizoma somewhat branching, throwing off thick fleshy fibrous roots. Leaves 1-2 inches 

 long, abruptly narrowed at the base into a petiole, of a dark dull green, marked with whitish 

 coarsely reticulated veins. Scape 8-12 inches or more in lieiglit, terete, pubescent, bearing 

 from 5-8 lanceolate scales. Flowers small, greenish white, in a close spike which is from 

 2-4 inches long. Bracts longer than the ovary, lanceolate, acuminate. Sepals broadly 

 ovale, obtuse, concave. Petals obliquely obovate. Lip deeply saccate, with a small abrupt 

 recurved acuminalion. Anther not mucronate. Summit of the column obscurelv 2-toothed 

 and mucronate. 



Shady fertile woods : frequent. Fl. July - August.

Rhizoma creeping and branching. Leaves 1-2 inches long, acute, entirely green, or much 

 less reticulated than in the preceding species, tapering at the base into a petiole. Scape 

 slender, bracteate. Spike 2-3 inches long ; the bracts and flowers more or less pubescent. 

 Sepals ovate, obtuse. Petals oblong. Lip moderately saccate, somewhat fleshy, with a 

 rather long slightly recurved acumination. Stigma with 2 teeth or short horns at the summit. 



Shady woods in the northern counties, and on the higher parts of the Catskill mountains. 

 Fl. July and August. Our specimens from the northern part of the State agree very well 

 with the European G. repens, but the Catskill plant differs in several points. The anther is 

 distinctly mucronate, and the summit of the column terminates in two long subulate processes.
