ODONTOGLOSSUAI 



1876:222. This species sometimes produces stout few- 

 fld. stems, which should be cut to save the vigor of the 

 plant. 



32. Euckerianum, Reichb. f. Related to O. crispum : 

 sepals and petals lanceolate, acute, creamy white, 

 bordered with violet and spotted with brown, waved; 

 labellum rather narrow, oblong, angular-lobed on each 

 side of the base, yellow at base, with few chestnut- 

 brown blotches ; callus rhomboid serrate. Colombia.
