23. Gametrophytes of botrychium
While botanizing in a fenced and unpastured timber lot on top of a hill one and a half miles south of Ladora, Iowa Co., Iowa, May 26, 1928, we found some very small leaves of Botrychium virginianum emerging from the ground cover of dead oak and elm leaves. On digging about them with a pocket knife, each leaf was found to arise from the side of a gametophyte. The soil was a fine dark brown leaf mold. The gametophytes lay about 12 cm. below the surface of the ground, and all were within a circle 15 cm. in diameter. They were irregular roundish tubers, dark brown and coarsely bristly outside, with one end - apparently "anterior" - of a paler color. The dense interior tissue was of the color and consistency of white potato. No studies of structure have been made.
