Species: Botrychium pedunculosum
Encyclopedia of Puget Sound
Stalked moonwort is a perennial with a single above ground frond up to 25 cm tall. It is divided into two segments that share a common stalk. The lower common stalk is usually reddish brown and the upper part of the plant is a dull green. The mostly sterile segment is conspicuously stalked and once to twice pinnatifid with up to five pairs of primary pinnae. The pinnae have irregular lobes and vary from pinnatifid to bifid to narrowly fan shaped and the lower ones often bear sporangia. The fertile segment is longer than the sterile segment and bears grape-like sporangia that contain thousands of spores; larger plants usually have two large ascending lateral branches.
