THE PHANEROGAMS OF THE JUAN FERNANDEZ ISLANDS 219 



Puente (no. 289); also Santa Clara (no. 1212) and Morro de los Alelfes, which 

 derives its name from it. Possibly sown by the fishermen in all these places. — 

 Masafuera: O. de las Casas, the colony. 



50. Fragaria chilensis Ehrh. Johow 1. c. 92. — Masatierra: Mrs. 

 GRAHAM etc.; V. Colonial (Johow) and Villagra (Johow); found by us in 

 Portezuelo by the path (no. 10). — *Masafuera: in the interior of Q. de las 

 Casas. Introduced with the convicts in 1909; cultivated in the gardens of the 

 abandoned Chozas Village. — Chile. 



51. Acaena argentea Ruiz et Paw JOHOW 1. c. 92. -- Masatierra: 



One of the most widespread and noxious weeds, in the basal region and on 

 the ridges, covering the ground for large stretches (no. 113, 113 b, t.grandiceps 

 Bitter; no. 113 c, 171, 1239). ^ n Masatierra, it has hybridized with Margyri- 

 carpns, see above p. 133. — *Masafuera: Las Chozas; Q, de las Casas, behind 

 the colony (no. 459, near f. pluribracteata Bitter). 



Professor BITTER remarks to this species: »Sowohl bei Pflanzen von 

 Masatierra (Nr. 113, 113 c) als auch von Masafuera (Nr. 459) habe ich bis 

 6 jochige Blatter angetroffen; die untersten Blattchen waren aber meist winzig, 

 schmal lineal, viel kleiner als die wohl ausgebildeten Nebenblatter. Die beiden 

 auf Juan Fernandez gefundenen Formen der A. argentea (f. grand iceps Bitt. in 

 Bibl. Bot. 74, S. 217 als var.) und f. pluribracteata (ibid. S. 216) weichen our 

 wenig von den festlandischen Formen der in Chile weit verbreiteten Art ab, 

 wahrscheinlich gehen sie auch in einander iiber; ich habe jedoch vom Festland 

 weder so grosskopfige noch mit so auffallig zu mehreren am Schaft verteilten 

 reducierten Blattern versehene Exemplare gesehen.» 



52. Medicago sativa L. — JOHOW 1. c. 89. — Masatierra: Common
