Thoiigli aberrant tliis plant is, I tliink, bcst placée! in tlie genus 

 Cystorcliis. Habitus and inflorescence are wholly tliose of a Cystorcliis, 

 tlie lip, however, not only lacks a rcal spiir as in C. apliylla RiDl.. but 

 also the vesicles at tlie base of thc lip, which are présent in ail species 

 hitlierto described, are practically wanting- In othcr respects viz. tlie callosities 

 on the sides of the lip, which is also thickened inside, and thc apical lamina 

 it agrées vvitli Cystorcliis. The columii and anther are longer than usual. 



„Stem light violet; leaves silky green above, violet beneath, flowers
