B. Andine Forms. 
f. 3, jucunda (Fée). — Syn. Aspidium jucundum Feée, 10. mém, 41. 1865 (excl. t, 42 f. 1). 
Dryopteris formosa Maxon, Contr. U. S. Nat. Herb. 18: 17. 1909, 
In its typical form that occurs in southern Mexico to Costa Rica this differs 
mainly from f. genuina by its smaller size: lamina 20—30 cm long and_ broad, 
3-pinnate—4-pinnatifid, seldom 4-pinnate; texture thinner, colour often fresh green, 
and the scales of the rhizome smaller and fewer. Ultimate segments variable in 
shape, from ovate to oblong, their teeth spinulose. Indusium small, deciduous, its 
sinus often very low. 
—Panama—Colombia are often considerably 
larger, rivalizing the typical form in size, but otherwise they do not differ from the 
true jucunda. From f. genuina they differ, as a rule, by their more open lamina with 
more oblong ultimate segments, 
Maxon has named this form D. formosa (Fée), believing it to be Fée’s Aspidium 
formosum and separable from D. denticulata; now he agrees with me that this is 
not the case and that the name formosa properly must be applied to that Cuban 
species previously known as D. cubensis (Mett.) O. Ktze., under which the question 
is discussed. The original D. jucundum Fée is Mexican (GALEOTTI nr. 6563, not seen).

f. 4. var. barbensis nov. var. — Fig. 25 b. — Large, about as f. genuina, 5- 
or even 6-pinnate; ultimate segments small, oblanceolate, scarcely 5 mm long, 2—3 
mm broad, very close. Texture herbaceous, slack. Sori one to each segment, small, 
indusium vaulted, deciduous. — In habit not unlike D. formosa, ‘but the scales and 
teeth are like those of f. jucunda.
