Ferns in this genus of ptisana are generally quite large, with fronds often reaching 2 to 3 m in length. Distinct sutures at the point of leaflet attachment, deeply cut synangia, and the absence of labiate sporangial apertures. Ptisana has a palaeotropical distribution, with the westernmost extreme of the range in Ascension Island and extending eastward through tropical Africa, Asia, and Oceania.
Propagation:
Propagation of ptisana can be achieved through spore sowing and division. Success depends on humidity, indirect light, and well-draining, organic-rich soil. Key steps involve collecting spores or divisions, sowing in sterilized peat, and maintaining consistent moisture and high humidity without waterlogging.
