this in habit is the purple poppy-mallow, Callirrhoé involucrata, 
f our western area, a member of the mallow family, with its 
long trailing stems and carrot-like roots. The flowers are a rich 
rple and very attractive. Another worthy representative of 
this family is the Virginia mallow, Sida hermaphrodita, a native 
of the Virginias and southern Pennsylvania; the flowers are 
white and small for the size of the plant, its ae value lying in 
its imposing foliage of five- para leaves and tall growth, some-

the Aryngium aquaticum, sometimes called rattlesnake master, 
probably from some reputed value. It increases rapidly, soon 
forming large masses which send up their large odd leaves

umbels of showy bright orange flowers, while the other forms 
a strong contrast to this, ae slight, smooth stems, rarely ex- 
ceeding a foot and a-half, whorled linear leaves, and cream- 
colored flowers borne in delicate bels. Anotier representa-
