Described from several living and dried specimens. The 

 drawing was made from plants collected on Table Mt. The species 

 is very distinct, in general habit most nearly resembling luxuriant 

 specimens of Z). tabularis, Sond., but readily distinguished from 

 that by its twice larger flowers, and its thin, straight, intrusely- 

 set spur.
