NOTE ON THE INVOLUCRAL LEAVES OF SYNDESMON.
Reading edition
F. H. Burglehaus.
Syndesmon thalictroides is described in Britton & Brown’s Flora as having sessile involucral leaves, which character is contradicted in the plants growing in the vicinity of Toledo. Careful observation during the past season fails to reveal a single instance of sessile involucral leaves, and most of the specimens examined have these leaves borne on petioles from one-fourth to one-half inch in length. Should like to hear from others concerning this feature of one of our most beautiful and dainty spring flowers.
