(no. 1 183); Q. de las Casas, growing on the rocky wall not far from the en^ 

 trance; and also found in the canyon on a fallen tree (no. 546). 



All the numerous specimens collected belong to the genuine P. lanceola- 

 tum and no form seen can with any right be placed under Gymnogramme 

 elongata (Sw.) Hook. HEMSLEY says that the subspecies had been collected 

 once but that he had not seen specimens. Johovv had two species in 1893; 

 in 1896 he merges P. lanceolatum into Gr. elongata, evidently unaware of the 

 differences between the two types. It seems certain that only one form occurs 

 in the islands, and, therefore, G. elongata must be excluded form the list. 



Some of the specimens are very large (leaves 25 cm long by 2V2 cm 

 wide) and several have the edges of the upper part sinuate. No. 32 includes 

 several frond with the tips once or twice furcate or cleft into three lobes. 



Area of distribution: Pantropical; also in Chile. 



Elaphoglossum Schott 



*45. E. Lindenii (Bory) Moore. C. Chr. Ind. 310. — Syn. Acrostichum 

 Lindenii Bory; Fee Acrost. 48 tab. 18 f. 3. 



Masatierra: north precipice of Co Piramide, c. 600 m, among mosses on 

 a narrow ledge; very few specimens seen (no. 193). 



A most interesting addition to the flora of the islands. The few plants 

 found agree in all details with the Mexican' form described as Acrostichum ve- 

 nustum Liebm. A possible explanation of the occurrence of this species in the 

 islands is given under Polypodium pyenocarpum above; the mountain wall where 

 it was found faces the North and will be struck by the rare but strong north- 

 erly storms. 



Area of distribution: Tropical America; Masatierra. Not in Chile. 



Gleicheniaceae. 



Gleichenia Smith 



While Hemslev listed two species of Gleichenia, G. cryptocarpa Hook, 

 and G. revoluta H. B. K., evidently overlooking that Hooker in Syn. Fil. 13 

 quoted the locality »Juan Fernandez, Bertero», for G. pedalis (Klf.) Spr., JOHOW's 

 list contains only G. pedalis, as he believed that both species listed by Hems 

 LEY were incorrectly named and only represented G. pedalis. In this he is 

 quite right: G. cryptocarpa, quoted on the authority of PHILIPPI (Bot. Zeit. 

 1856: 631) is shown by the specimens in Mus. Nac. Santiago to be G. pedalis 

 (they were thus labelled by PHILIPPI himself), and Mr. WRIGTH kindly informs 

 us that DoWNTON's specimen of G. revoluta in the Kew Herbarium is G. peda- 

 lis and that MoSELEY's fragmentary plant also belongs to the same species. 

 Thus, only one species of the genus was hitherto known from the islands.
