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 are with long
petioles and branch out sporophylls; the trophophyll's rhachises
cleft theｍselves in three, and the segments are in the shape of a
broad ovate, with the tips obtuse, margins with obtuse serrations,
both rachises and petioles without hairs. The sporophylls are longer
than the trophophylls; strobili set on the upper parts bi-to tri-pinnately
branches, put spherical sporangia in a conical way, mature in
autumn, and then wither. |
