600 m (no. 360). — Only collected once before in Masatierra: REED(!) without 

 locality. 



*Masafuera: Q. del Mono, dense forest, 475 m (no. 388); Q. de las 

 Chozas, in the forest; 0. de las Casas, innermost part of the canyon, under 

 stones below the cascade, 215 m (no. 465); Q. Loberfa, under stones and in 

 moss between huge blocks, 180—300 m (no. 481). — New for Masafuera, where 

 fine, richly fertile specimens were collected in O. de las Casas. 



The specimens belong to the typical form. 



Area of distribution: South Chile, Valdivia to Western Patagonia (49 

 S. L.); Juan Fernandez. South Brazil. 



8. II. fuciforme Sw. Syn. 148 (1806) et auctt; C. Chr. Ind. 361 (where 

 for »China austr.» read » Chile austr.»); Hemsl. 67; Johow 1893: 41, f. 28, 1896: 

 170; C. Chr. Arkiv for Bot. 10: 24 (1910). -- Syn. H. semiteres Colla 1836: 

 32, tab. 61. 



Humid montane forests in rich soil or on decaying trunks, not observed 

 below 480 m. (Fertile Dec. — Jan.) 



Masatierra: Slope of C. Chifladores, above the Frances valley, c. 500 m; 

 V. Anson, slopes of El Yunque, 480 m; near the road to Portezuelo, c. 500 m 

 (no. 138); north face of Co Piramide, with the preceding; Q. Villagra, mountain 

 spur W. of El Yunque, c. 500 m and at the road-side in the highest part of 

 the Villagra valley below the pass, c. 500 m (also JoHOW). 



This species, the largest of the genus, varies in cutting from tri- to quadri- 

 pinnatifid. The less divided form is not, as we supposed in 1910, the only 

 one found in the island. Specimens in the present collection are quite as much 

 divided as specimens from Chile. 



Area of distribution: South Chile to Western Patagonia; Masatierra.

 H. Bcrieroi Hook. Sp. fil. 1: 93 tab. ^ C (1844); Gay 6: 534. 



Damp, shady forests of the highest mountain slopes, not found below 

 480 m; characteristic of the darkest corners in the fern groves. (Fertile in Jan.) 



Masatierra: C. Chifladores, woods in the highest part of the Frances 

 valley, on Dicksonia c. 500 m; the ridge between Q. Laura and Q. Piedra 

 agujeriada, c. 600 m and high up in this valley, 650 m; C. Centinela, under 

 old stumps, 530—560 m; V. Anson, slopes of El Yunque, 480 m (no. 159, also

 Q. Villagra, high up near the pass, rare.

 (no. 535). — New for this island. 



With this characteristic species most authors unite //. Frankliniae Colenso 

 from New Zealand, to which it is so closely related that it is not unnatural to
