This is a more robust plant than D. pusilla witii all free pinnae auiicled on 

 both sides of the base and the central ones lobed with subpinnale secondary veins. 

 D. coarctala has most pinnæ regularly pinnatifid and a scaleless rachis. D. sagittala 

 is apparently similar, but it belongs to ,^ Goniopteris and its hairs are stellate.

Type from Panama, eastern slope of Chiriqui Volcano, 2100 — 2300m; leg. 

 Maxon nr. 5294 (W). 



Rhizomate erecto, breve, dense radicante, squamis parvis ovatis parce onusto. 

 Stipitibus dense fasciculatis, gracilibus, rubrescentibus, nitidis, ad basin sparse palea- 

 ceis, glabris, 6 — 10 cm longis. Lamina anguste lanceolata, ad 22 cm longa, medio 

 3 — 4 cm lata, versus basin breviter attenuala, gramineo-viridi, firmo-herbacea, bi- 

 pinnatifida; rachi gracili, brevissime et tenuissime puberula. Pinnis multijugis, 

 sessilibus, alternis vel inferioribus suboppositis, falcatis, infimis 2 — 3 paris auri- 

 culiformibus, medialibus maximis, 2— 2'/^ cm longis, basi 5—8 mm lalis, acutis, 

 supra ad costas sparse setosis, infra ubique glandulosis, inaequaliter pinnatifidis. 

 Laciniis 6 — 7-jugis, ovato-oblongis, obliquis, acutis, anterioribus majoribus, basali 

 anteriore semper maxima, posterioribus minoribus, basali minima. Venis simpli- 

 cibus, 3— 4-jugis. Soris supramedialibus, indusio late affixo glanduloso persistente 

 obtectis. Sporangiis glabris. 



This new species resembles very much certain forms of /). sancta, mainly in 

 size and its unequal-sided pinnæ; it differs by its indusiate sori and its lamina 

 being shortly narrowed downwards about as in D. concinna or I). Limligii, but its 

 real affinity is with I), sancta and I), pseiidosancta. The indusium is peculiar; it 

 is glossy, red-brown and impressed in the centre, while the free edges are greenish 

 or whitish and glandular; it is not exactly reniform but rather variable in shape. 

 To this species I refer Spruce nr. 5297 (RB) from Ecuador that is rather 

 typical and further two other specimens, which are not glandular beneath and 

 somewhat more pubescent but agree in size and shape of pinnæ:

pi. tab. 1658. 

 Type from Colombia, Province of Antioquia, leg. Kalbreyer nr. 1454(Kew!). 

 A remarkable species well figured by Baker. It belongs to the small group 

 of Ü. sancta by its narrow leaf and unequal-sided pinnæ dillering from all other
