Botrychium ternatum: A
fern putting forth buds in autumn and winter, withering in early
summer, and growing in sunny locations in fields and mountains.
Trophophylls have long petioles and branch out sporophylls; the
trophophyll's rhachises are cleft into three, and the segments are
in the shape of a broad ovate, with the tips obtuse, margins with
obtuse serrations, and both rachises and petioles without hairs. The
sporophylls are longer than the trophophylls; strobili set on the
upper parts bi-to tri-pinnately branch, producing spherical
sporangia conically, mature in autumn, and then wither. |
