304. Dryopteris chiriquiana n. sp. 
Type from Panama, leg. Maxon nr. 5729 (W!) 
Species D. hirtae et D. oophyllae proxima, differt major, minus incisa, costis 
costulisque subtus parcius paleaceis, paleis nec bullatis, et pilis articulatis Ctenitidis 
molliter pubescentibus; indusiis perparvis. 
Rhizome thick, erect, densely clothed with castaneous, entire, lanceolate scales. 
Stipites fasciculated, about 20 cm long, brownish, like rachis with similar but 
smaller, retrorse scales and finely glanduloso-puberulous by minute, appressed, 
deciduous hairs. Lamina about 20 ecm long, 15—20 em broad, deltoideo-ovate, fresh 
green, firmly herbaceous, tripinnatifid below, bipinnate-bipinnatifid at the. middle. 
Pinne about 10-jugate, basal ones opposite, short-stalked, about 10 cm long, scarcely 
longer than the next following, bipinnatifid at base, their lower side somewhat pro- 
duced with the basal lower pinnula a little longer than the next. Middle pinne 
short-stalked or sessile, ovate-oblong, broadest at base, upcurved, acuminate, at base 
incised to midrib. Secondary pinnules or segments oblong, broadly adnate and de- 
_ current, the lower ones of larger pinnz free, obtuse or subacute, about !/2 em broad, 
_ those of the lower half of the 2—3 pairs of lower pinne pinnatifid, lobed or ser- 
: rated into subfalcate, acute lobes or teeth, those of the upper half of the leaf mostly
