18 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



southward to Costa Rica, as evidenced by the following specimens in the U. S. 

 National Herbarium: 



Mexico: District of Cordoba, State of Vera Cruz, Fink 33a. 

 Guatemala: San Miguel Uspantan, Department of Quiche, altitude 1,800 

 meters, Heyde & Lux (J. D. S. 3243). Forest near Tactic, Alta Verapaz, 

 von Turckheim, December, 1879 (without number). 

 Costa Rica: Estrella, Province of Cartago, altitude 1,320 meters, Cooper. 

 Mountains 5 miles south of Cartago, altitude about 1,800 meters, Maxon 515. 

 Forets de l'Achiote, volcan de Poas, altitude 2,200 meters, Tonduz 10698. 

 Without exact locality, Cooper; Werctle. 

 With regard to the Aspidium jucundum of Fee mentioned above, it is not stated 

 whether this was figured from the Cuban or the supposed Mexican element; pre- 

 sumably upon the Cuban, however, for the plate and description agree well with 

 the Cuban plant described afterwards by Mettenius" as Aspidium cubense, with 

 Wright's no. 1099 as type, and no Mexican specimens similar to this have been seen. 

 It may be noted that the alliance of these, as well as of Fee's A. gracilipes and A. 

 tenerum, both Brazilian, is with Dryopteris denticulate (Sw.) Kuntze. 



Dryopteris lanceolata (Baker) Kuntze. 

 II. 839. Cubilquitz, altitude 350 meters, July, 1907. 

 II. 1620. Coban, altitude 1,350 meters, January, 1907. 

 II. 1621. Near Coban, altitude 1,600 meters, February, 1908. 

 The first two specimens cited above were distributed under the name Nephrodium 

 salvinii Baker. The species is known only from Guatemala. Other specimens, all 

 from the province of Alta Verapaz, are: 



Pansamala, altitude 1,140 meters, von Turckheim (J. D. S. 626; distributed as 

 Nephrodium hirtura; identification changed later to N. salvini Baker.). 

 Pansamala, altitude 1,140 meters, John Donnell Smith 1563 (distributed as 

 N. salvini). Cubilquitz, altitude 350 meters, von Turckheim (J. D. S. 

 8647). Senahu, Cook & Griggs 482. 



Dryopteris longicaudata (Liebm.) Maxon. 



Poly podium longicaudatum Liebm. Vid. Selsk. Skr. V. 1: 209. 1849. 



II. 1691. High forest near Purulha, altitude 1,800 meters, April, 1907. 



The specimens accord perfectly with Liebmann's very full description and agree 

 also with the following in the U. S. National Herbarium: 

 Mexico: District of Cordoba, State of Vera Cruz, Fink 67£. 

 Guatemala: Near the Finca Sepacuite, Alta Verapaz, Cook & Griggs 178; 613. 



This species is of the group of Dryopteris rotundatu (Willd.) C. Chr., a species 

 founded upon Plumicr's plate 38, representing a Martinique plant. To this arc- 

 referred also by Christensen J "oly podium ftavopunctatum Kaulf., founded upon Mar- 

 tinique and Montserrat plants, and Nephrodium imrayanum Hook., originally from 

 Dominica. All three were kept distinct by Hooker, yet are closely related, and 

 perhaps are only extreme forms of a single highly variable species. The Mexican 

 and Guatemalan plant is notable for the narrow and long-decurrent bases of the 

 pinna;, the rachis being alate throughout, only the lowermost pinnae free and long- 

 cuneate. 



The sori are nonindusiate, and the veins are normally quite free. In the Fink 

 specimen, however, the lowermost pair of veins is joined casually, the resulting vein 

 sometimes irregularly short-excurrent.
