Fig. 2. 



A SINGLE FLOWER OF THE STEER'S HEAD. 



The horns represent the two lower petals. Between them is shown a 

 sepal ("forelock"), the other sepal of the pair being behind and invisible 

 in the drawing. The "snout" is formed of the upper petals, which are pro- 

 longed downward into a terminal spoon-shaped process which covers the 

 anthers and stigma. One of the petals is behind and thus invisible in the 

 drawing. The figure is one and one-half times natural size.
