is also well illustrated by the length of the tail-like appendage 

 of the seed. The height at the plant and size of the leaf does 

 not exhibit much constancy, since the plant varies according 

 to the circumstances of its habitat. The following arrange- 

 ment is principally based on the seed-character, and will, I 

 hope, be a more natural one than treating them as distinct 

 species. I have to add here that I have not been able to 

 examine the seed of the form * ondakensis,' so that I cannot 

 place it in its proper position, but satisfy myself for the pre- 

 sent by placing it near var. rigidula as the fourth variety.
