Drosera, from the Greek, droseros (droseros), "dewy, watery"; intermedia, from the Latin, "intermediate";
Sundews
trap insects on the sticky, muciligenic hairs then digest them. New
Jersey has three species of sundews: spatulate leaved (intermedia),
round leaved (rotundifolia) and thread leaved (filiformis).
Witmer
Stone, in 1910, wrote "This seems to be the most abundant and most
generally distributed species of Sundew in South Jersey. There is
considerable variation in the size and appearance of the plannts. Those
of drier situations have a dense rosette-like cluster of small leaves
from which the flower scape arises, while those growing in water or wet
sphagnum develop a leafy stem often six or seven inches long; the
uppermost leaves, from the midst of which the scape springs, being
always the largest and freshest" (468).
Blooms slightly earlier than Drosera rotundifolia. D. filiformous blooms earliest.
Mary
Treat of Vineland researched Droseraceae and corresponded with Charles
Darwin regarding her research. For more information on this
