75. Dryopteris Rimbachii Ros. Fedde, Repert. 7: 147. 1909. 
Type from Ecuador, Mt. Tunguragua, 2500 m, leg. Rimpacn nr. 119 (R! CC). 
Well-marked by its coriaceous lamina and long basal scales; the leaf is very 
shortly narrowed towards the base and bears 2—3 pairs of close, auriculiform 
pinnz. In general habit it resembles closely D. Pavoniana, specimens of which 
were collected at the same locality by Dr. RrwBACH (nr. 118, R, CC), but that spe- 
cies has a long-creeping, branched rhizome and wants the long basal scales and 
auriculiform pinne. 
76. Dryopteris brachypus (Sod.) C. Chr. comb. nov. 
Syn. Nephrodium brachypus Sod. Rec. 43. 1883; Cr. vase. quit. 228. 1893. 
Type from Ecuador, ad viam Quito-Guayaquil, leg. Soprro (specim. auth. 
in Kew). 
Rhizome erect, up to 15cm long, 1cm thick, like the base of stipe densely 
clothed with narrow, subulate, brown, firm, finely hairy, squarrose scales; similar 
scales are scattered along the stipe and rachis, but they are deciduous and not al- 
ways found. Stipites fasciculated, about 10 em long, finely hairy. Lamina 40—70 cm 
long, 10—15 cm broad, downwards gradually but rather shortly attenuate, firmly 
membranous, not glossy above, pale green beneath, the upperside finely pubescent 
by adpressed hairs, the channelled costa more decidedly strigose, the underside 
nearly glabrous; rachis sulcate and hairy above. Middle pinnz 6—9 cm long, 
1'/s —3?/|1 em broad, shortly acuminate, the lower ones gradually shortened, the 
lowermost auriculiform, about 1 cm long. Segments a little oblique, acute, larger 
ones often faintly toothed, the basal ones equal. Veins 5—7-jugate, simple, rather 
indistinct. Sori close to the margin with glabrous sporangia; indusium not seen; 
according to Soprno it is puberulous. 
D. brachypus is in general habit not unlike D. oligocarpa; it is best character- 
ized by its numerous basal, squarrose scales, agreeing in this character with the 
two following species; these three species (and perhaps D. Rimbachii) form a 
proper little group marked by the said character. 
77. Dryopteris supranitens Christ, Fedde, Repert. S: 19. 1910. 
Type from Costa Rica, Tablazo, Finca Haberl, A. et C. BRADE nr. 270 (R!); 
specimens from Panama, Chiriqui, Maxow nr. 5244 (W) are very alike. 
Closely related to tablaziensis with similar basal scales; it differs by its rigid 
texture, glossy upperside, narrower lamina that is suddenly narrowed downwards 
with 4—5 pairs of distant glanduliform pinne (type IV), by its sparse pubescence 
and long-acuminated pinna. From JD. brachypus it differs in shape of lamina and 
nearly glabrous upperside. — A peculiar form with the segments distinctly ser- 
rated is Maxon’s nr. 5524 from Panama (W).
