218 ACROSTICHUM, § ELA PHOGLOSSUM. 



49. A. (Elaphoglossum) Martinicense, Desv. ; " fronds 

 rigid coriaceous opaque linear long-attenuated below decurrent 

 very glabrous smooth, veins lying at an angle of 45°, margins 

 revolute ; fertile fronds scarcely broader than the sterile, 

 stipes longer, margins plane repand, costa broad canaliculate, 

 younger ones with the margins plicate, caudex creeping thick 

 as a child's finger, scales lanceolate margined with long arti- 

 culated or sometimes strangulated hairs/' F'ee. — Desv. in Fee,

Hab. Tropical America : Souffriere, Guadeloupe, Parker, " one specimen pass- 

 ing into ^. simplex;" Cuba, C. Wright, n. 789; Jamaica, M'Fadyen; Guiana, 

 Schoniburlk, n. 447, Appun, n. 138 ; Brazil, Baua de Rio Negro, Spruce, n. 

 1426. — Many other localities are given by Moore, but which I have not the 

 means of identifying. Fee's figures of A. Martinicense, t. 16, f. 3, well repre- 

 sent our plant from Cuba ; they are taller and more graceful than our Mexican 

 and Guadeloupe ones. In our plants the fronds are 6-8 inches long, quite nar- 

 row, spear-shaped, sharply acuminated, and narrowly attenuated below, every- 

 where glabrous and scaleless ; stipites 2-3-6 inches long. 



50. A. (Elaphoglossum) leptophyllum, Fee; " fronds linear 

 rather obtuse attenuated at the base, petioles helveolous, 

 scales ovate acuminate dentate ; sterile ones thicker, costa 

 narrowly canaliculate ; fertile ones larger longer stipitate, 

 caudex creeping thick as a goose-quill clothed with soft ful- 

 vous scales." — Fee, Acrost. p. 45. t. I7. /. 1. Elaphoglos- 

 sum, Moore. 



Hab. Brazil, 5/ancAe/. " Venezuela, jPe?«rf/er, w. 276, 277 " {3Ioore). — "Elle 

 differe de VA. Martinicense par des petioles libres de tout parenchyme et paleaces 

 k la base, par des lames terminees en pointe emoussee, par la nature des squames 

 de rhizome," etc. Some of my specimens under A. affine much resemble M. 

 Fee's figures, as do Fendler's Acrost. from Venezuela, n. 276 and 277. 



51. A. (Elaphoglossum) Calaguala, Kl. ; caudex thick 

 clothed with small black glossy straight (not flexuose) subu- 

 late imbricated scales, stipites crowded at the extremity of 

 the branches reddish-brown as well as the rather stout bright 

 reddish costa and both (at the base especially) rough with small 

 blackish rather rigid scales, stipites of the sterile fronds 1 inch 

 long, of the fertile ones 4 inches ; fronds coriaceous reddish- 

 brown, sterile ones 3-4 inches long \ of an inch wide linear 

 very obtuse and very long and narrowly attenuated upon the 

 stipes lepidote above being sparsely dotted with very minute 

 whitish closely pressed irregularly orbicular scales which are 

 more numerous and patent at the margin beneath indistinctly
