 ihe siructure of ihe otber Aspisias, and not a double caudicula , as appeared Irom 

 the drawing ol Mr. Descourtilz , on which ihe species was founded. The flowers 

 bave long, narrowed sepals and petals yellowish blotched wiib browri; ibe lip is large 

 and wbiie. and is slained in ihe niiddle wilh pale purple, which had not, in ihe spe- 

 cimens seni us, tbat disiinci cresceut form from which the name has been derived.
