A slraggling plant. with yellow flowers spotted witli brown. Tbc petals are 

 broader ihan ibe sepals. more ovaie , and like them very acuie. The crest consists 

 of fivc long, blunt. somewhat cylindrical. rugged processes next ibc column , and 

 three olhers raili^-r hirgcr in front. It is much like ramosum (no. 185), but tbe crest 

 is totally difl^erent, wiih none of ihe additional ihreads and varicosilics of ibatspecies. 

 It al.so seems to be a jdant wiih a more lax panicle.
