habit, and very coriaceous texture, it is, however, that of a new and 

 very distinct species of high andine habit, distinguished by the 

 glabrous upper surface, the scales along the lower part of the costse 

 beneath, and by the crisped, lax pubescence of the rachis and of the 

 costae and costules beneath. 



DRYOPTERIS LANIPES C. Chr., sp. nov. 



Guatemala: Pinula, Depart. Guatemala, 4,300 ft., /. Donncll Smith 2462, 

 April, 1889, type; U. S. National Herbarium, No. 828979. 



Endryopteris rhizomate obliquo-erecto, i cm. crasso. Stipitibus 

 fasciculatis, ad auriculas infimas a.d 12 cm. longis, stramineis, pilis 

 mollibus luteo-albidis patentibus ad 5 mm. longis densissime vestitis. 

 Lamina lanceolata, 5-6 dm. longa, medio 15 cm. lata, ad basin sub- 

 abrupte valde reducta, ad apicein serratum vel integrum breviter 

 acuminata, subcoriacea vel papyracea, luteo-viridi, rachi straminea 

 maxime ad basin pilis mollibus patentibus luteo-albidis dense vestita, 

 bipinnatifida. Pinnis oppositis vel subalternis, sessilibus, inferioribus 

 3-4 jugis gradatim abbreviatis, infra has 3-4 jugis subito valde 

 reductis auriculiformibus ca. i mm. longis et latis, medialibus maxi- 

 mis 8 cm. longis, 1.5 cm. latis, subfalcatis, utrinque glaberrimis vel 

 subtus ad costas pilis longis nonnullis deciduis instructis, apice 

 integro breviter acuminata excepto pinnatifidis, superioribus serratis 

 vel integris. Laciniis approximatis, sinubus rotundis angustis sepa- 

 ratis, integris, parum obliquis, acutis, 2.5 mm. latis, basalibus 

 aequalibus vel posteriore paulo longiore. \'enis distinctis, approxi- 

 matis, ca. 10 jugis, simplicibus. Soris margini approximatis, parvis ; 

 indusiis deciduis, glabris. Sporangiis glabris. 



This new species is different from all known species by the pecu- 

 liar lanose pubescence of the stem and lower part of the rachis. It 

 is evidently a member of the Sprengelii group, although it is rather 

 small and has few veins, which, however, are closely placed. In 

 color it is not unlike typical D. chcilanthoides from Brazil. Remark- 

 able also is the reduction of the lamina. Below the 3 or 4 pairs of 

 gradually reduced pinnae is a similar number of suddenly reduced 

 very small auricles, not glanduliform w^arts, as in certain species of 

 the Sprengelii group. Further must be mentioned the nearly entire 

 upper pinnae. The position of the species in my ''system" must be 

 before no. yG, D. strigifcra. 



To this species belongs, I have no doubt, as a forma minor, Don- 

 nell Smith's no. 2463, also from Guatemala (Department of Guate- 

 mala, 4800 ft.). It is quite identical in pubescence, but smaller (20
