the decurrent pinnae. Most of the specimens mentioned differ, however, 

 considerably from the former species by its shorter lamina, fewer and 

 much broader pinnse with irregularly lobed or only faintly crenate or 

 repand edges, and by its frequently irregularly anastomosing veins (fig. 

 11). It is possible that the original specimen belongs to true S. longi- 

 caudata, and that the form, here called alloeoptera, is a variety of that 

 species with broad pinnae. 



9. Stigmatopteris caudata (Raddi) — fig. 12. 



Syn. Polypodium caudatum Raddi, Opusc. sci. Bol. 3: 288, 1819, 

 PI. Bras. 1: 25 tab. 39. 1825; Kaulf. Enum. 113. 1824; Dryopteris 

 caudata G. Chr. Ind. 257. 1905. 



Type from S. Brazil, described both by Raddi and Kaulfuss 

 under the same name. The species was very well figured by Raddi, and 

 the plant of Kaulfuss is, as shown by an original specimen^ leg. Mertens 

 (HH) a narrower form of the same. Although considerably varying in 

 size and in breadth of the lobes, which are deeply toothed in their whole 

 length or only faintly toothed in their outer third, the following specimens 

 from S. Brazil must all be referred to this well-known species.

 Expl. Exp. 1838-42 n. 23 (HW).

Generally the lamina is distinctly pellucido-punctate ; the immersed 

 glands are in some specimens few, in others numerous, but varying con- 

 siderably in size in the same leaf. 



S. caudata is recorded also from the Andes and from the West 

 Indies. The specimens seen from these localities belong, however, to the 

 following species.

Syn. Polypodium ichtiosmum Sodiro, Recensio: 59. 1883; Gr. vase,

Type from Ecuador, Sodiro (HG); in the same country gathered 

 by Stiibel n. 797 (HB). 



Golombia, Schhm n. 1683 (HG). 



A larger species than S. caudata with pinnae sometimes more than 

 30 cm. long, 4 — 5 cm. broad; segments patent or a little oblique, sepa- 

 rated by rather narrow sinuses sharply toothed in the outer third, rather
