THE PTBRIDOPHYTA OF THE JUAN FERNANDEZ [SLANOS 



43 



••.((). G. quadripartita (Poir.) Moore, Ind. 382 (1862); C. Chr. hid. 324. 

 Only in the Alpine region, in sheltered places. Rare. (Fertile Feb. 



March.) 



Masafuera, in the highest parts: The Correspondencia Camp, in the ravine, 

 1 160 m (no. 409); Las Torres, 1370 m; C. del B'arril, 1290 m; Los Inocentes, 



1375 m. — New for Juan Fernandez. 



The specimens agree closely with an anthentical specimen leg. COMMER 

 SON, Herb. Haun. The primary branches are sometimes once, sometimes twice 

 furcate. Younger leaves decidedly glandulose, especially beneath. 



This species is often confounded with G. cryptocarpa Hook., but it is not 

 proliferous although having a scaly bud in the primary furcation; the costae 

 and costules are rather densely chaffy with rufous scales and flaccid hairs, the 

 edges revolute but not covering the sporangia, and the slender, branched rhi- 

 zome is very sparingly paleaceous with ovate, peltate, appressed, very deciduous 

 scales, while the rhizome of G. cryptocarpa is stronger and more densely and 

 permanently paleaceous. 



Area of distribution: Llanquihue to Fuegia; Masafuera. 



47. G. pedalis (Kaulf.) Spr. Syst. 4: 26 (1827); Johow 1893: 20 f. 1, 

 1896: 153. — Syn. Mertensia pedalis Kaulf. Enum. 39 (1824). 



Rocky ridges in dry, sunny places, very local. (Fertile in March.) 

 Masatierra: V. Colonial, near the road to Portezuelo, 3 — 400 m, forming 

 small beds in places (no. 563); C. Central, on the narrow crest, 570 m; C. Sal- 

 sipuedes, narrow ridge between O. Salsipuedes and Q. Helechos, c. 500 m, Q. 

 Villagra, low ridge near the camping place, c. 200 m. 



The specimens are rather typical, still the costa and costules are per- 

 fectly destitute of scales; both surfaces are finely glandulose by minute, glist- 

 ening glands. 



Area of distribution: Cordilleras of Southern Chile; maritime provinces 

 from Valdivia to the Chonos Islands; Masatierra. 



*48. G. cf. litoralis (Phil.) C. Chr. Ind. 322. 



Masafuera: The Correspondencia Camp, in the ravine, very scarce (no. 403.) 

 Sterile specimens from Masafuera that resemble G. pedalis in colour, veins, 

 structure of scales and growth, but differ in its palaceous costae and costules; 

 the scale are rufous, paler with age, ciliate, those of the costules lacerate, 

 small, all leaving small red spots when falling; it also differs in the shape of 

 the segments, which are broader below, gradually tapering toward the apex 

 and finally in the primary branches being twice furcate, carrying segments 

 above quite to the base, naked outwards from the first to the second furcation. 

 Typical G. pedalis, as a rule, has the primary branches prolonged without seg- 

 ments on both sides save for a larger one close to the furcation. After 

 inspection, Prof. HlERONYMUS informs as that it stands near litoralis of Phi- 

 lippi, which has narrower scales on the midrib.
