form of D. IJndiyii of a somewhat firmer U-xtiiie, but the specimen is too incom- 

 plete for a certain identification willi Ü. Liiuligli. 



16. Dryopteris Galanderi (Hier.) C. Chr. Ind. 267. 1905. 



Syn. Aspidiiim Galanderi Hieron. Engl. Jahrb. 22: 369. 1896. 



Tvi)e from Argentina: Sierra de la Eslanzuela, leg. C. Galander (HB!). 



Besides this ralher incomplete specimen I refer here a plant from Brazil: 

 Lagoa Santa, E. Warming (HH), from which I supplement the original diagnosis 

 with the following: 



Rhizomate adscendente, nudo, c. 3"^' cm. crasso. Stipitibus I'/u dem. longis, 

 rigidis, stramineis, basi fuscescentibus, glabris, ad basin squamis nonnullis sub- 

 rigidis, opacis, mox deeiduis instructis. Lamina lanceolata, ä'/a — 6'/2 dem. longa, 

 medio 15 cm. lata, coriacea. Pinnis inferioribus distantibus, 3—4 jugis reductis, 

 inlimis minimis, a jugo superiore 4 cm. remolis, omnibus exacte oppositis, sub- 

 horizontalibus, glabris vel denudatis, inlerdum sparse ciliatis, subtus sparse glan- 

 dulosis. Laciniis basalibus majoribus. Venis 7—8 jugis, simplicibus vel in laciniis 

 basalibus furcatis. 



Very near D. oligocarpa and especially Ü. argentina, but distinguished by its 

 coriaceous lamina and opposite pinnæ. 



17. Dryopteris laevigata (Mett.) C. Chr. Index 273. 1905 — [Fig. lOJ. 



Syn. Phegopteris laevigata Melt.; Kuhn, Linnaea 36: 112. 1869; Pohjpodiuin 

 lacvigatiim Bak. Syn. Fil. 505 (non 348). 1874; Pohjpodium Lechleri Bak. Ann. of 

 Bot. 5: 456. 1891. 



Type from Peru: Tatanara, leg. Lechler n. 2628 (HB!). 



Stem and rachis dark-purplish, shining, like 

 the subcoriaceous lamina quite glabrous, 4 pair 

 of distant (3'/3 cm.) glanduliform pinnæ, lowest 

 pair of developed pinnæ scarcely abbreviated. 

 Pinnæ opposite, 4'/3 cm. long, I'/l- cm. broad with 

 distinct circular aërophore. Segments few, some- 

 what oblique, obtuse, the edges somewhat revolute; 

 veins 5 — 6 to a side; sori exindusiate, about me- 

 dial. Developed lamina 40 cm. long.

 From the type spcciiiieii. 



18. Dryopteris Pavoniana (Klolzsch) C. Chr. Ind. 283. 1905. 



Syn. Pohjpodium Pavonianum Klotzscli, Linnaea 20: 386. 1847; Phegopteris 

 Pavoniana Mett.; Kuhn, Linnaea 36: 112. 1869; Nephrodium Pavonianum Hieron. 

 Engl. Jahrb. 34: 445. 1904. 



Tj'pe from Peru, leg. Ruiz i.<: Pavon n. 55 (HB!). ^- Further I refer here two 

 specimens from Peru and Bolivia, Mandon n. 16 (HB). 



This species is allied to D. oUgocdrpa, 1). argentina and D. Galanderi distinguished
