166 MENISCIUM. 



repando-dentate or obtusely crenate (not sharply serrated), 

 oostules horizontal very distinct, transverse soriferous veins 

 numerous but varying according to the breadth of the pinnae 

 prolonged into veinlets short or more generally continuous 

 to the margin, sori short and subrotund and appai-ently soli- 

 tary or geminate and more or less confluent into an ol)long 

 sorus or linear and extending in a more or less curved line 

 nearly from one costule to the adjacent one. — Siv. Syn. Fil.

 Le Prieur, n. 1396 (probably M. Guyanense, Fee, Gen. Fil. p. 224).— A very 

 variable species, it must be acknowledged, and further observations may yet prove 

 that the Meniscium cmpidatum, of Bl. Fil. Jav. p. 102, t. 45, is in reality neither 

 generally nor specifically distinct from this ; yet, on the other hand, I have mate- 

 rials for showing that that plant is one and the same as Polypodium (§ Gonio- 

 pblebium) uropliyllam.. Wall. ! See our remarks on that species, at p. 10 of this 

 volume. 



9. M. macrophyllmn, Kze.; " frond elliptical or oljlong mem- 

 branaceous glabrous pinnated, pinnae few alternate cune- 

 ato-decurrent at the unequal base upon the short petioles 

 which are dilated upwards acuminate, the margin sinuate and 

 slightly repand ; sterile ones elongato-lanceolate very large ; 

 fertile ones much smaller at both extremities much attenu- 

 ated, sori dense at length diffuse, costa and veins glabrous, 

 rachis and long stipes of both fronds tetragonous." — Kze. in 

 Schk. FiL Suppl. p. 93. t. 44. " Kze. in Comment, ad Martii 

 Herb. FL Braz. n. 362." 



Hab. Brazil, Bahia, Blanchet, near St. Sebastian, Martins. Cayenne, Le 

 Prieur. — I possess no exactly authentic specimen of this plant, but I have from 

 Blanchet, a Brazilian Meniscium, without name, which entirely corresponds with 

 Kunze's figure and description ; but I cannot feel satisfied that it is specifically dis- 

 tinct from AI. reticulatum. 



N.B. Our Meniscium Thwalfesii, briefly noticed in ' Filices Exotica;,' under 

 M. simplex, t. 83, appears to have iiivolucrate sori, and will probably have to be 

 referred to Axpleniece. It requires further investigation.
