1. Stigmatopteris rotundata (Willd.) — fig. 2. 



Syn. Aspidium rotioidatum Willd. spec. 5: 247. 1810; Dryopteris 

 rotundata G. Ghr. Ind. 289. 1905. Polypodiuni flavopunctatum Klf. 

 Enum. 108. 1824. 



This species was founded by Willdenow on Plumier tab. 38, which 

 illustrates a plant from Martinique and no doubt is the same species as 

 Pol. flavopunctatum Klf., based on Sieber Fl. Martin, n. 350, gathered 

 in the same island. With this specimen, the accepted type of the species, 

 agree the following West-Indian specimens. 



Montserrat, Ryan (HH). 



Martinique, Sieber n. 350 (HB), Isert (BR), Pere Duss n. 8 

 (HG), L'Herminier n. 115 (HB), Holm n. 37 (HB), Richard, Bot. Belang. 

 n. 821 (HB). 



Dominica, Imray n. 865 (HB), Eggers n. 668 (HB). F. E. Lloyd 

 1903 n. 902 (HW). 



St. Vincent, H. & H. Smith n. 659 (HB), Gheckley n. 7 (HB), 

 Eggers 6869 (HW). 



Guadeloupe, Duschassaing (HB), L'Herminier (HB, HG). 



Grenada, Mt. St. Gatharina, 2200', Eggers n. 6164 (HW), R. V. 

 Sherring n. 141 (HW). 



Trinidad, Hillebrand n. 355 (HB). 



The specimens from Guadeloupe differ from the type by rachis and 

 especially costse being densely clothed beneath with light-brown, ovate, 

 fringed scales; in the type the scales are very few. 

 var. trinidadensis n. var. 



Trinidad, Fendler n. 98 (HB, HW), Hart 3707 and 6259 (HG), 

 Hb. Trin. Bot. Garden 337 and 1236 (HW). 



Upper pinnae nearly entire, the lower ones with a cuneate base, ir- 

 regularly lobed; rachis rather scaly, the scales with papillose margins. 

 Veins irregular, very short or long and then sometimes connected. 



In southern Brazil a long series occur of forms, which probably are 

 all specifically distinct from S. rotundata. Intermediate between this 

 species and S. Carrii is the form described as Fhegopteris heterocarpa 

 Fee, Grypt. vase. Bresil 1: 100 tab. 30 fig. 2. 1869, Glaziou n. 2401 

 (HH, HRg). It resembles the former in general habit, the latter in its 

 more distant and more erect veins and in its sori being distinctly infra- 

 medial. From S. tijuccana it is distinguished mainly by its short lobes. 

 To this form I refer the following specimens in Hb. Ghrist.
