 R o ot  pyriform-bulbous,  invested  with  loose,  brownish  tunics,  
 shrivelled longitudinally, sheathing a bifoliate stem, and buried from  
 six to nine inches beneath the  surface  of the  ground;  subterraneous  
 portion of the stem white, shining, cylindrical and delicate, sometimes  
 slightly  angular.  Stem  above  ground,  sheathing  petioles,  
 and  a portion of the base of each leaf,  dull-purplish.  Leaves destitute  
 of veins, unequal, one  always narrower than the  other, lanceolate, 
   and oval-lanceolate, channelled, slightly undulate, and terminating  
 in  a  thick  acumination,  made  by  a  sudden converging  of  the  
 margins.  Young plants  of the first year have but one leaf, which is  
 often quite  elliptical,  (as fig.  3.)  next  year the plant sends  up two  
 leaves  and  a  flower.  Leaves  always  shining  and  glabrous,  and  
 maculated  by  large,  irregular  spots  of  reddish-brown  or  umber-  
 brown,  which give them the  appearance of  a dingy green.  Under  
 side of the leaves paler  and without spots.  Peduncle  radical, one-  
 flowered, proceeding from the point of meeting  of  the two  leaves,  
 about  five  or  six  inches  long,  cylindrical,  glabrous  and  shining,  
 greenish below, and yellowish  towards  the  summit.  Flower  consists  
 of  six  lanceolate,  reflected  petals;  the  three  outside  yellow, 
   acuminated,  striped  and  veined  with  dull  brownish-red;  the  
 three inner yellow, without stripes,  having a cartilaginous notch on  
 each side  near the base, and a longitudinal furrow running into the  
 small nectariferous pouch at base.  The inner side of  all the petals  
 spotted  with  long  dots of reddish  purple,  and  each  has  a stamen  
 better than half its length attached to its base.  Filaments broad, comis  
 rj.
