The Growth Pattern of Ophioglossoid Ferns: A Case Study of Botrychium lunaria (L.) Sw.
The family Ophioglossaceae is one of the oldest fern lineages, characterized by a specific sporophyte structure where each leaf is divided into a fertile (sporophore) and a sterile (trophophore) segment. The aims of this study were to analyze: (1) the growth rate and duration for each developmental...
