Flora Pittsburghensis

Orchidaceae

Helleborine (Epipactis helleborine). A spike of fascinating little orchid flowers, with broad pointed leaves alternate on the stem. The distinctive flowers have lips that look like little slippers filled with chocolate sauce. The color of the flowers is quite variable, according to botanical references; they may be yellowish, or green, or purple.  The species is quite uncommon around here, but weedily abundant in some places, such as Schenley Farms, where Helleborine grows abundantly on otherwise neatly kept shady front banks.
