 minute, in simple or pauicled racemes or spikes. Lip various ; spur long or short.

 truncate or short side lobes and a short triangular or reniform aduate erose or 

 n'mbriate midlobe which is warted or echinate on the disk. Column very short; strap 

 of globose pollinia linear. (Sp. 20-27). 



Sect. III. ACAMPE. Stem usually long and very stout. Leaves keeled, thickly 

 coriaceous. Flowers corymbose as in Calceolaria, rarely in large spreading panicles. 

 Lip as in Calceolaria, but with a thicker warted reniform or ovate midlobe (spur 

 cylindric in 8. ochraceurn). Column very short; strap of globose pollinia linear.
