Sceptridium dissectum leaves are a light green during the spring and early summer, with the leaves becoming deciduous in late summer. The leaves usually turn a bronze color in late fall through winter. The grape like sporangia range from green to yellow. The petiole or stalk of the plant is green from top to bottom and glabrous as is the ...
Fern spores are borne in sporangia which are usually clustered to form sori. The sporangia may be covered with a protective coating called an indusium. The arrangement of the sporangia is important in classification. [6] In monomorphic ferns, the fertile and sterile leaves look morphologically the same, and both are able to photosynthesize.
The fern has spores on the bottom of the fronds, contained in sori. Sori can be found aligned in rows on the underside of fertile fronds. They start as yellow, but as they mature, they turn brown and split. [13] The fern sporulates in summer and early fall. Rhizome sections are also viable offspring and can root themselves in new medium.
Propagating ferns from spores is a delightful process, but requires a fair bit of time. If you're looking for instant gratification, propagating from rhizome is an easier way—although plants may ...
The sori, producing the spores, are large and round. Like many tree ferns, it features a "skirt" of dead leaves that do not drop off the crown and form a barrier for parasitic climbing plants.

Fern spores require light to germinate. [8] Following major disturbances that clear or reduce plant life, the ground would receive ample sunlight that may promote spore germination. Some species' spores contain chlorophyll , which hastens germination and may aid rapid colonization of clear ground.
An annulus in botany is for ferns an arc or a ring of specialized cells on the sporangium. These cells are arranged in a single row, and are associated with the release or dispersal of spores. In mosses it is a ring of cells around the tip of the sporangium. In flowers it is a ring of hairs within the flower tube.
The ferns also develop hanging fertile fronds that can reach up to 2 metres long. [2] Both fertile and non-fertile fronds are broad and branching and grown to resemble the horns of a stag or elk, thus the common names stag horn or elk horn. [2] The plant gives off many tiny spores that drift to nearby trees to reproduce. [3]
