Xanthosoma sagittifolium. Gerald McCarthy. (Vick’s Ill. Month. 
Mag., ix., p. 42.) 
This Aroid grows abundantly in certain boggy localities about 
Wilmington, North Carolina, and is locally known as Spoon 
Flower and Wilmington Lily. Its general habit and appearance 
is much like that of Sagittaria, but the leaves are more 
glossy and very dark green. It blooms from the first of June to 
the middle of July; the spathe is pure white and spoon shaped. 
The plant has a long tap root covered with warty excrescences 
and long, string-like fibres by which it is attached to the roots of 
the trees among which it grows. The large, coral-red seeds ripen 
about the beginning of September. 
Zamia integrifolia (Gard. Chron., xxvi., p. 146.) 
Prof. Sargent writes: “That in Florida this Cycad is largely 
cultivated for the sake of the starch contained in its roots, great 
quantities of the starch being made for the Key West and West — 
Indian markets,”
