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
conically, mature in autumn, and then wither. |
