NO. 15] Pyxie ( Dyapensiace<z.) 121 



balls may be found nearly the year around, and its blos- 

 soms from spring to fall. Moreover, it has but slight care 

 concerning location. It rather prefers damp, rich ground, 

 but it thrives also in the sandiest and driest. It can ac- 

 complish something more perhaps where sun and sand are 

 not against it ; but the pretty little thing seems equally 

 happy everywhere.
