Dutchman's Pipe
Aristolochia macrophylla
(old A. durior)
Birthwort Family
A strange flower, the tubular calyx is J-shaped with three lobes (that may appear to be joined) around a dark opening that
gives access to insects, by which the flower is pollinated. Dutchman's Pipe is a native vine. The best way
to find them is by searching for the large heart-shaped leaves that twine up tree trunks, then look under the leaves for the
inconspicuous flowers, which vary in color from yellow to reddish-brown. This one is on Hwy 276 in Pisgah Forest, NC but are widespread throughout the
area... photo 17 May, 2004.
