Broadhurst: Struthiopteris in North America 381 



Type: Fee, Mem. Foug. n: pi. 5- 1866; from Guadeloupe. 



Distribution: Known from Guadeloupe, Dominica, and Mar- 

 tinique. 



Specimens included: Guadeloupe: Duss 4165 (Y), Duss 

 3710 (Y). Dominica: Laudat, Lloyd 315 (Y, N). Martinique: 

 Montagne Pelee, Duss 4163 (Y). 



This species shows great variation in size, texture, and in the 

 length and apices of the pinnae; most of the smaller coriaceous 

 ones bear legends indicating that they are from high altitudes and 

 the sides of volcanoes. Parallel information is wanting, however, 

 for the larger specimens. The colored stipes and the heavy, 

 lacerate, whitish-dotted fertile pinnae are apparently common to 

 all mature specimens. Fee describes the sterile stipes as bearing 

 short, remote spines, which are not present on our specimens or 

 in his figure; the numerous projections figured on it resemble the 

 dried, viscid scales described above. 



24. Struthiopteris vivipara Broadh. sp. nov. 



Plants terrestrial. Rhizome 3 cm. thick in the fragment seen, 

 the scales very few, 2-2.5 cm. long, 4-6 mm. broad, brown umber, 

 more or less plicate. Sterile fronds 85-90 cm. long; stipes 24-25 

 cm. long, angulate, vestigial pinnae present throughout, shining 

 mahogany, the scales light brownish yellow, deciduous, shapeless 

 and wholly appressed to the stipe, their attachment indicated as in 

 S. lineata; lamina 64-66 cm. long, 28-30 cm. wide, oblong, 

 abruptly reduced at the base (type A, with vestigial pinnae), not 

 reduced at the apex, the terminal pinna 12-15 cm. long, viviparous 

 at or very near the apex of the rachis; pinnae 15-16-jugate, oblong- 

 lanceolate but broadest at the cordate base, straight or occasionally 

 very slightly curved near the apex, the apex acute, never long- 

 acuminate, the base cordate and free throughout, mostly sessile 

 and the rachis covered by the bases of the pinnae, the lower pinnae 

 petioled, 15 cm. long, 3-3.5 cm. wide; margins serrate, slightly 

 or not at all revolute; leaf tissue rigid-herbaceous, the costae 

 much like the stipe but also finely chaffy or fibrillose, the lower 

 surface of the pinnae decidedly and finely araneous over the once 

 forked veins; veins distinctly grooved above, raised below and 

 more perpendicular than in most species of the genus (except 

 the wider S. striata specimens), the vein spaces 12-14 to I cm. 

 Sporophyls 1 15-125 cm. long; stipes 34-45 cm. long, vestigial 

 pinnae barely visible; lamina 68-78 cm. long, abruptly reduced 

 at the base, not gradually reduced at the apex; pinnae I5 -I 7 _
