What is sporangia in Psilotum?
The sporangia of Psilotum are trilocular synangia resulting from the fusion of three adjacent sporangia, and these are borne laterally on the axes. In the rhyniophytes and trimerophytes the sporangia were single and in a terminal position on branches.
Do Psilophyta have roots?
Phylum Psilophyta. They look very similar to 400 million year old fossils. They have no roots or leaves, just a photosynthetic stem. They can either grow in the ground or be epiphytes (growing on the stem or branches of another plant).
Is Psilotum a bryophyte?
In Psilotum, much like in bryophytes (especially mosses), the embryo starts out with a single pole of growth that points away from the foot. Growth from the apical cell of this pole produces the undifferentiated branching sporophyte axis (Fig. 5).
Where are whisk fern found?

What are whisk ferns used for?
The species is still often used in making traditional Hawaiian leis. Its common name, whisk fern, alludes to its use in the past as a small broom, made by tying a handful of its branches together.
Do whisk ferns have roots?
A whisk fern has water- and food-conducting tissues but lacks true leaves and roots. Photosynthesis occurs in the aerial stems, and water and mineral absorption occurs in the horizontal underground rootlike stems (rhizomes), which receive water and nutrients from fungi through a mycorrhizal association.
