it. Coste and costule above antrorsely strigose and the veins with scattered setee, the 
margins ciliated; coste, costule and veins beneath densely and shortly tomentose 
partly by short Ctenitis-hairs, partly by some -slender and somewhat longer hairs, 
and scaly; leaf-tissue of under-surface densely and minutely downy by short, erect 
hairs. Sori small, exindusiate. 
By its bright-brown, thin scales this species resembles D. ampla, but the whole 
Structure of the frond shows that its real affinity is to species of the group of 
D. subincisa. It differs from all andine species of that group by its bright-brown 
scales; in pubescence and scales of the rachis it is similar to D. squamosissima, 
but it lacks the rigid, castaneous scales and it is much smaller. It comes near to 
D. atrogrisea in size and cutting, but differs in colour and pubescence. — CHRIST 
referred to this species two specimens, one from Pont du Navarro, the rhizome of 
which was described by the collector »comme rampant et entortillé A Végal de 
Pteridium«, the other from Luna, which is described as »semi-arborescente«, It is 
clear that those two specimens must be two quite different things; the former is 
unknown to me. : 
Dryopteris vasta var. bogotensis Hieron. Hedwigia 46: 347. 1907 from Colom- 
bia: Bogota, Stipe nr. -434 (B) is a critical form much resembling D. lunensis in 
size, colour and bright scales, but the scales of the rachis are finely toothed and 
_ the underside nearly glabrous; still there are traces of a tomentum, and it seems 
better to place this fern provisionally under D. Iunensis as a variety than under 
D. vasta. 
330. Dryopteris pansamalensis pn. Sp. 
Similis formae minori D. villosae, exindusiata, paleis basalibus ovatis, inte- 
gerrimis, pubescentia densiore. Habitu D. atrogriseae similis, differt: paleis valde 
diversis, pilis numerosioribus, omnibus longis, articulatis, soris medialibus vel 
supramedialibus. 
This new species is no doubt a near ally of D. villosa; it is smaller and 
apparently exindusiate. In general habit it is very similar to D. atrogrisea, from 
which it differs clearly by its broad, entire, brighter scales and the more numerous 
and longer hairs; the hairs of the upperside are rather many and not confined to 
the veins. As a whole it is more long-hairy than any other species of the group. 
Pinne of largest specimen seen 35 cm long; pinnules broadly obtuse with 6—8 
subentire segments to each side; those of the largest specimen acuminate with about 
15 pairs of tertiary, broadly obtuse segment, the lower of which are again pinnatifid. 
The posterior basal segment of the upper pinnules are adnate with their whole 
base to the costa, and their midvein springs out from the costa up to 2 mm from 
the base of the costula. . 
a _ Although the specimens referred here are different in size and degree of divi- 
sion, they no doubt all belong to the same Species. The smaller specimens (nr.
