236 Pteridophyten. 



generic name Ananthacorus Underw & Maxon is proposed, the sole 

 species being A. angustijolius (Sw.) Underw. & Maxon , of wide 

 distribution in the American tropics. The relationship of this is with 

 Vittaria, from which it differs radically in its type of venation which 

 is strictly areolate without lateral veins. 



VIl! Miscellaneous notes and changes of name. The distribution 

 of Asplenium conqiiisitum Underw. & Maxon is indicated, specimens 

 being cited from Jamaica and Guatemala; the type is from 

 Jamaica, Maxon 1558. Diplasiuni oreophyhim Underw. & Maxon is 

 a new name given to Jamaican plants wrongl}'' described byjenman 

 under the name Asplenmm franconis Mett. Dryopteris oligophylla 

 Maxon is a new name given to the tropical American fern first de- 

 scribed under the invalid name Polypodiiim invismn Sw. (1788), 

 usually known under the invalid name Nephrodiuni Sloanei Baker; 

 specimens are cited, and the reason for the erroneous reference of 

 Nephvodiuin paucijugum Jenman to this species is indicated. Dryo- 

 pteris pyrarnidata (Fee) Maxon {Goniopteris pyramidata Fee), described 

 from Guadeloupe, is reported from Santo Domingo; it is a 

 true Dryopteris, not of the section Goniopteris. Dryopteris radicans 

 (L.) Maxon is the new name given to plants known usually as Ne- 

 phrodiuni reptans Diels, the various Synonyms being: Asplenium 

 radicans L. (1759), A. rhisophvUum L., Sp. PL ed. 2, 1540, 1763 (not 

 L., Sp. PL ed. 1, 1078, 1753; Sp. PL ed. 2, 1536, 1763), A, rhisophorum 

 L. (1764), Polypodiiim reptans GmeL, etc., etc., all of which were 

 founded upon Sloane's plates representing a species oi Dryopteris \ 

 there is no evidence that any Aspleniinn formed a part of tliese; the 

 synonym}/- is explained in considerable detail. A somewhat similar 

 confusion has existed in the case of Dryopteris serndata (Sw.) C. 

 Chr., of which Polypodiiim asplenioides Sw. is a true synonym; the 

 synonymy is discussed. Goniophlehiiini ampliatiim Maxon is a new 

 name given to Polypodiiim gladiatiun Kunze, 1834, (not Vell. 1827), 

 a species known from Jamaica and Cuba and incorrectly merged 

 with P. attenuatum H. & B., from which it differs constantly in 

 various characters, especially in its more numerous and deeply im- 

 pressed or pustulate sori, these commonly borne in four rows. It is 

 pointed out that Polypodium Kalbreyeri Baker (1886) is an earlier 

 name for P. transiens Lindm., the latter having been proposed as a 

 Substitute for P. longipes Fee (invalidated by P. longipes Link); the 

 species is known from Brazil, Guiana, Colombia, and Costa 

 Ri c a. The following new combinations are published : Phymatodes 

 nematorhison (D. C. Eaton) Underw. {Polypodiiim. nematorhison D. C. 

 Eaton), known previously only from Trinidad, now reported from 

 the Island of Margarita, Venezuela; Polystichum solitariiim 

 Maxon) Underw. {Polystichum mtinitum solitariiim Maxon), from 

 Guadeloupe Island, Mexico; Tectaria martinicensis (Spreng.) 

 Maxon (sjm. Aspidiiim martinicense Spreng., A. macrophyllum Sw.); 

 Tectaria plantaginea (Jacq.) Maxon [Polypodiiim plantagineum Jacq.); 

 Tectaria piirdiaei (Jenman) Maxon {Aspidium Purdiaei Jenman). 



Vin. New species in several genera. Asploiium sarcodes Maxon, 

 sp. nov. , the type from Cuba, related to A. sanguinolentum Kunze; 

 known also from Porto Rico. Cheilanthes aemiila Maxon, sp. nov., 

 the type from Victoria, Tamaulipas, Mexico, E. Palmer 187; 

 somewhat related to C. microphylla. Cheilanthes peninsularis Maxon, 

 sp. nov., the type from Lower California, Mexico; related to C. 

 Pringlei, Diplasium delitescens Maxon, sp. nov,, the type from Cuba; 

 known also from Honduras and Panama; remarkable for its
