Along the roadsides and in the black oak woods of the sand country there blossom in summer the bright flowers of poppy mallow. It is a color and a form not common in this pari of the country; and the poppy mallow is so splendid that it might seem to be a garden flower escaped to the woods.
Callirhoe triangulata (Leavenw.) A. Gray.
July - August Sands.
Poppy mallow is fairly common in the sand country, especially along Route l00 between Beardstown and Meredosia, and further north in the sands of the Havana region. It is one of the plants typical of the sands; in a haunt restricted to a specialized flora, it stands out as a beautiful flower.
The flowers are the typical mallow form- five petals, squared off and notched, arranged around a center composed of a club-shaped concentration of stamens and pistil. The petals are a silky, glistening, bright magenta-rose or lavender-rose, occasionally pure white. They stand erect on thin, wiry stems on plants which sometimes recline upon the sands. The upper leaves are narrow or three-parted, the lower leaves long and triangular or halberd-shaped, the lowermost heart-shaped. Many forms of leaves appear on one plant. They are thin, waxy, rough, and dark green.
Poppy mallow is found in the Bandy black oak woods where New Jersey tea, rabbit's bean, lead plant, aromatic sumac, and prickly pear cacti are common. It blooms from June throughout August.
