surfaces is also minutely hairy and without glands. Stipe long, up to 30 em to 
the lowermost pair of glanduliform pinnz, these in 3—4 very distant pairs and 
above them 3—4 pairs of auriculiform pinnz. Larger segments often serrate, linear- 
oblong or ligulate, 3-—4 mm broad with 10— 15 pairs of veins thatfare more distant 
than in D. Sprengelii; basal segments of lower pinnz not much reduced. Sori very 
close to the margin; indusium small, hairy, soon falling. Sporangia glabrous.

Type from Ecuador, Mt. Tunguragua, Spruce nr. 5254 (RB!). 
A most distinct species with long slender pinnae of thin texture and fully 
pinnate in the lower half. Evidently a near ally of the preceding species and of 
D. Mercurii, in pubescence and lack af glands resembling D. conformis, but basal 
pinnule much reduced, veins more numerous and sori not so close to the margin.

Type from Costa Rica, Irazu, leg. BRADE nr. 245 (RI). 
Of this I have seen a single leaf only and I dare not decide with certainty 
whether it is a good species or not. It is not improbable that it is a thin-leaved 
form of D. rudis or D. nervosa.

D. consanguinea (Fée) C. Chr. (see above nr. 59) may be a small form of this.
