obtuse. Gostae and costulae beneath rather densely squamose. Veins 

 10 — 12 or more, simple or with a very short anterior branch, on which 

 the sori appear to be apical. Sori about medial, generally with an in- 

 ferior, indusium-like scale. Lamina distinctly pellucido-punctate by numerous, 

 rather large immersed glands. 



To this species I refer the West-Indian fern hitherto determined as 

 P. caudatum; the specimens seen agree, as to the essential characters, 

 very well with the andine type, although they very much resemble S. 

 caudata by their acute, oblique segments, which are toothed throughout.

Syn. Aspidium caudatum var. contractum Christ, Bull. L'Herb. 

 Boiss. II. 6: 162. 1906. 



Type from Costa Rica, Navarro, leg. Werckle 1905 (HC, HW). 



A near ally of D. ichtiosma, from which it may be distinguished by 

 1) its size, 2) its subdimorph leaves and 3) its sessile pinnae with the 

 basal segments both considerably larger than the other ones. Leaf pro- 

 bably more than IV2 m. high; lower pinnae of sterile leaves up to 5 

 dcm. long by 10 cm. broad, unequal-sided, incised to a narrow wing to 

 the costa. Segments patent, the posterior ones much the largest, sub- 

 acuminate and lobed more than Vs of the way down with the veins 

 pinnate in the lobes. — Fertile leaves with narrower more distant seg- 

 ments, which are almost entire or obtusely serrate, falcate and separated 

 by broad, open sinuses. Veins about 10, rarely forked, indistinct. Sori 

 inframedial with inferior, indusium-like scale. — Leaves firm, rather thick, 

 dark- green, distinctly pellucido-punctate. Scales few. 



12. Stigmatopteris pellucido-punctata G. Chr. — fig. 15. 



Syn. Polypodium macrophyllum Hook. sp. 4: 241. 1862 (non Mett.); 

 Dryopteris pellucido-punctata G. Chr. Ind. 283. 1905. 

 Type from Peru, Tarapota, Spruce n. 4720. 

 Of this I have seen only two segments of the type specimen (HB).
