 5. 2. blephariglottis. 3. cristata. 



4. * Integra. Lip oblong-, entire, long-er than the mner 

 petals; spur longer than the germ, acute at the point; stem 

 leafly, bractes shorter than the flowers. Hab. In the 

 swamps of New Jersey. Nearly allied to O. ciliaris and 

 with flowers of the same orange-yellow colour, but some- 

 what smaller. 



5. * nivea. Lip linear-oblong, entire, longer than the 

 inner petals; spur filiform, equal, longer than the germ; 

 segments of the corolla spreading; spike short and oblong; 

 lower leaves linear and very long, cauline subulate. Hab. 

 Betwixt St. Mary's and Satilla river. West Florida. — Dr. 

 Baldwyn, who favoured me with a specimen under the 

 above name. Flowers clear white, rather small. Lower 

 leaves narrow, a span long, upper ones disproportionately 

 small; bractes shorter than the germ. Genitaliferous co- 

 lumn remarkably small in proportion, not half so large as 

 the preceding, the pollinia are consequently subsessile. 

 Spike rather dense, J or 3 inches long. 



6. Java. Lip ovate, entire, partly crenulate; spur at- 

 tenuated, fihfoim and about ihe length of the germ; spike 

 crowded; bractes longer than the flowers. Hab. In New
