Pseudobulbs roundish, commonly 2, but sometimes 3 or 4 and rarely as many as 5, con- 

 nected in a string by a thick fibre. Leaf 4-6 inches long and 1^-3 inches wide, elliptical, 

 acute, petiolate, plaited and marked with numerous prominent nerves which converge at each 

 end : petiole inserted on the summit of the bulb. Scape 12-15 inches high, arising from 

 the side of the bulb, with 3 rather loose acute sheaths, purplish. Flowers 10 - 20 in a loose 

 raceme, of a dull yellowish brown mixed with purple : pedicels with small lanceolate bracts 

 at the base. Sepals and petals linear-oblong. Lip shorter than the petals, 3-lobed, obtuse : 

 middle lobe undulate and crenulate on the margm ; the palate prominently ridged, white 

 speckled with purple. Column slightly curved, shorter than the lip. Lid of the anther 

 roundish, caducous. 



Woods, in rich vegetable mould : rare. Western and northern part of the State {Dr. Gray 

 ^ Dr. Bradley) ; Washington county {Dr. M. Stevenson) ; north part of Westchester county, 

 near Long Island Sound (Dr. Meat?). Fi. middle of May. Fr. October. A new bulb, which is 

 connected with the preceding one by a thick fibre, is produced every year, and the old usually 

 remains till a third bulb is formed at the end of the season, when the first withers away ; 

 but sometimes they last for several years. The new leaf is formed in midsummer, remains 

 through the winter, and withers away about the time of flowering. The bulbs contain a large 

 quantity of viscid matter, which does not, however, answer as a cement, as asserted by Pursh.
