DRYOPTERIS PIEDRENSIS C. Chr., sp. nov. 



Cuba: Upper slopes and summit of Gran Piedra, Oriente 900 to 1,200 

 meters, Maxon 4041, type ; U. S. National Herbarium, No. 522690. 



Biidryoptcris rhizomate erecto-obliquo, radicibus numerosis. 

 Stipitibus fasciculatis, gracilibus, angulatis, stramineis, 15 cm. longis, 

 minute hirtis, ad basin squamis paucis brunneis instructis. Lamina 

 lanceolata, 50-60 cm. longa, 15 cm. lata, utrinque attenuata, firmo- 

 membranacea vel papyracea, graminea, rachi tenui brevissime 

 puberula, bipinnatifida. Pinnis 2.5-3 cm. inter se remotis, alternis. 

 horizontalibus, sessilibus, inferioribus 3-5 jugis gradatim abbreviatis, 

 infimis auriculiformibus hastatis, inframedialibus maximis, oblongo- 

 lanceolatis, 7.5 cm. longis, 1.5 cm. latis, ad apicem serratum acumi- 

 natum sensim attenuatis, supra pilis microscopicis rigidis rudis. 

 subtus ad costas costulasque brevissime puberulis et glandulis rubris 

 sparse obtectis, ad alam vix 0.5 mm. latam pinnatifidis vel ad basin 

 perfecte pinnatis. Laciniis ca. 20 jugis, basalibus aequalibus vel 

 parum reductis, posteriori auricula interna instructa, superioribus 

 obliquis vel subfalcatis, ca. 2 mm. latis, subacutis vel obtusis, margin- 

 ibus integris vel leviter crenatis revolutis. Venis indivisis, 8-9 jugis, 

 utrinque prominulis. Soris margini approximatis, parvis ; indusiis 

 minimis, mox deciduis, glandulosis, ciliatis. Sporangiis glabris. 



This species is in size, shape of the lamina, and pubescence, almost 

 identical with D. concinna, but it differs from that species by (i) its 

 glabrous sporangia, (2) its firm lamina with prominent veins and 

 reflexed margins, which partly cover the sori. In these respects it 

 may be compared to D. scalptur aides, which, however, is much more 

 hairy and has many pairs of reduced pinnae. The basal pair of 

 segments is in the larger pinnae quite free. 



DRYOPTERIS COLUMBIANA C. Chr. 



(Revision 279, No. 9, Fig. 8.) 



Colombia: Cauca, Lehmann 2968. 



I now prefer to refer here this number, determined previously by 

 Hieronymus and myself as D. oligocarpa, from which it differs by 

 its longer leaf and by the shorter pubescence of the rachis. Never-
