Aspidium tenerum Fée, Cr. vasc. Br. 1: 147. 1869, 
Rhizome oblique with a fair number of dark-brown, + 
narrow, weak, often crisped scales. Stipes fasciculated, 
often 10—15, castaneous, 6—10 cm long. Lamina_ ovate 
or ovate-oblong, seldom subdeltoid, 10—15 cm_ long, 
8—12 cm broad, subcoriaceous, 3-pinnate, 4-pinnatifid. 
Ultimate segments ovate, shortly cuneate on the posterior 
side, the margins more or less deeply lobed, the apex Fig 36 Seneca y ihale of D. 
rounded with 3—4 triangular, acute teeth. Indusia brown,  genticulata var. aperta, nat. size. 
reniform, subpersistent. Spores papillose. 
The typical Jaeta, excellently figured by Swartz and Hooker (loc. cit.) is 
apparently not very closely allied to D. denticulata and it might be very natural to 
deal with it as a valid species. Still it is impossible to draw a definite line between 
it and the following f. gracilipes; in some specimens some leaves are typical laeta, 
others gracilipes and this is sometimes difficult to distinguish from some of the 
smaller Andine forms. The larger gracilipes is a form of the humid forests of the 
coast sierras, the smaller, more rigid /aeta a reduced form from the drier plateaus 
of Minas Geraes. 3

Differs mainly from typical laefa by its longer stipe, larger, less rigid and 
generally deltoid lamina, 15—-25 cm long and broad, and by its commonly longer 
(but scarcely aristate) teeth of the segments.
