182 VITTARIA. 



** Sporangiasters mastoid, claviform. 15, 16. 



15. "V. stricta, Carm. Herb.; fronds linear coriaceous 

 opaque thick rigid striated, costa broad, margins revolute ob- 

 tuse at the apex the base stipitiform, sori rather remote from 

 the reflexed margin deeply immersed, caudex creeping scaly, 

 scales cinereous lanceolate very long-acuminate the margin 

 entire." Fee. — Carm. in Linn. Trans. xW.p. 513. V. revoluta. 

 Fee, Vittar. 21. 19. Pteris vittarioides, Thouars, FL Trist. 

 d'Acimha, p. 31. t. 1. 



Hab. Tristan d'Acunha, Du Petit Thouars, Carmichael, in Herb, nostr. — My 

 specimens are 1 foot to IG inches long, IJ scarcely 2 lines wide. Petit Thenars' 

 specimens appear to have been very small. Fee compares them to the pods of 

 Vanilla. 



16. Y. filifolia, Fee ; "fronds linear acute tapering below 

 into a long fihform fructiferous stipes, sori extraniarginal 

 when young covered with a plicature of the margin, sulcus 

 broad occuj)ying a third part of the lamina running from 

 the base to the apex, caudex thick the scr les brown lanceo- 

 late denticulate flexuose at the margin." Fee, Vittar. p. 20. 

 t. 3./. 6.— Teenitis linearis. Mart, and Gal. Fil. Mex. p. 144 

 [Fee). 



Kab. Columbia Linden {iyi Herb, nostr.), Jurgensen. Mexico, Galeotti, n. 

 6337. Guadeloupe, etc. — 10-12-14 inches long, httlc more than a line wide. 

 I fear this may be found in not a few herbaria under the name of lineata ; but M. 

 Fee tells us it differs from that and isoetifolia and tenera by the trigonous or cor- 

 diform spores. 



*** Sporangiasters cuculliform. 17. 



17. Y . scabrida, Kl. ; fronds linear more or less obtuse 

 and more or less elongated, veins spathulate, sori flexuose 

 continuous, sulcus deep (sulco cavo), the margins subindusi- 

 form, scales lanceolate toothed at the margin." Fee. — Kl. in 

 Fee, Vittar. p. 20. 



Ilab. Brazil, Sellow. Mexico, Schiede. — The fronds of my specimens from 

 Dr. Klotzsch are 2 inches long, 1 line widein the broadest part, tapering gradually 

 downwards so as to be subspathulate. 



C. Spores rounded (sjjorangiasters none). 18, 18*. 



18. Y.falcata, Kze.; "fronds rigid thick acute, costa con- 

 tinuous, caudex erect fibrillose, sori endophyllous, the margin 

 of the sulcus gaping." Fee, Vittar. p. 20. /. 4./. 1. 



Ilab. Java (Fee). Mount Ophir, Malacca, Griffith, in Herb, nostr. — " Fdix 

 pnsilla, habitu Tcenitidis linearis. Les frondes sont cpaisses et portees par uu 

 caudex dressee. On ne pent le confoudre avec nulle autre." The fronds of our 

 plants are 3-5 inches long, 1 2 line wide. The caudices are certainly erect.
