Some New American Species of Dryopteris 81 



The following two species were not dealt with in the 

 first part of my monograph. An examination of authen- 

 tic specimens of both shows that they ought to have 

 been included in the groups of species there treated. 



Dryopteris (Goniopterut) trinidadensis (Jenm.) C. 



Chr. Ind. 298. 1905. 

 Poly podium trinida dense Jenm. Gard. Chron. III. 



,s Falls, J. H. Hart, Bot. Gard. 



Herb. Trinidad no. 5886 (Kew!). 



The single sheet in the Kew Herbarium, consisting of 

 one leaf without rhizome, named by Jenman, shows ft 

 plant that in habit resembles Stigmatopteris Carm and 

 allied species very much, but is in reality a Goniopteris 

 of the section Eugoniopteris. It agrees in nearly all 

 characters with D. strain! nea (Bak.) C. Chr. and may be 

 a form of that species. It differs from it in its acute or 

 even submucroiuilate teeth, the serrated acuminate 

 apex of the pinnae (which are about 1.5 cm. broad , 

 the non-gnnmiferous rachis (an accidental character, 

 and by having only 2 or 3 tertiary veins on each side ot 

 the secondary vein, the two basal ones terminating m 

 the leaf-tissue and free, the upper ones running out to 

 the thickened margin. In size, color, perfectly glabrou* 

 frond, stramineous costae, shape of pinnae, son ana 

 kind of venation, the two forms wholly agree. Having 

 seen only the rather fragmentary authentic W™™£? 



both, it is not possible to decide now whether D. frw»*J 

 derm* is a form of D. stranunea; but I am ™ ch mc ^ 

 to so regard it. Dryopteris stran»i»ea was desenbea 



from a single leal collected by Fend er (no. 4,4) 



Tovar, Venezuela, a locality very rich in ferns, many 

 of which are found also in Trinidad.
