Des. — Fronds numerous, pinnate, linear, from 3 to 6 inches high, 
of a very light green color. Pinnae petioled, alternate, the upper 
ones ovate, the lower roundly triangular, attached to the rachis by 
the centre of one of the sides, which is somewhat truncate, the 
other two sides being regularly and deeply crenate, sometimes 
doubly so. Rachis quite green, except at the lower part. Sori 
reddish brown, two to six on each pinnae, confined to the middle 
of it, finally becoming confluent, but even then not extending to 
the margin. 
This is immediately distinguished from the last by the lighter colour of all 
its parts, less spreading sori, and differently shaped and alternate pinnae, added 
to which the pinnae on the lower part of the frond are generally distant, and 
those near the top of the frond crowded, while the whole is very delicate and 
elegant. Sometimes the frond is divided into two, as represented in Bolton, 
t, 2, f. 3, when it becomes the Trichomanes ramosum of authors ; but this 
branching is an accidental circumstance, and by no means constant, it therefore 
does not constitute a variety, more especially as not more than two or three 
branched fronds are found upon a plant, all the rest being of the common 
character and appearance.
