Botrychium lunaria (L.) Sw. f. incisum (Ophioglossaceae) (Finland, Lohja, Hermala, 1991). – Image: Harri Harmaja (scanned from dried specimen). – Besides the incised leaf lobes, this plant from limestone rock is remarkable as having a few sporangia in the normally sterile part of the leaf! In the same summer I found f. incisum (with normal placement of sporangia) also in a near-by locality (Lohja, Kokkila, 1991).
