or the sides inflexed or reflexed, orbicular and emarginate ;

 (P. humile, Mill. Diet. No. 2. 176S.) Dwakf pea. Low, a

 greenish : peduncles usually shorter, often little exceeding 

 the stipules : leaves sometimes spotted with gray : pod and

BEANS 



Garden beans represent several species, but all the com- 

 mon hinds in North America are very tender to frost 

 and require a warm season and sunny exposure; soil 

 should be open and light, but fertile; seed is sown where 

 the plants are to grow; usually grown in drills, except 

 the tall hinds; the common bush beans are partial-season 

 plants.
