THE PHANEROGAMS OF THE JUAN FERNANDEZ ISLANDS 225 



ambigua DC, and collected by SCOULER; C. ambigua is a synonym of E. 

 linifolius. 



*II4. Xanthium spinosum L. — Masatierra : On a road in the 

 colony (no. 627). — Also in Chile. 



115. Bidens leucantha (L.) Willd. — Johow 1. c. 52. — Masatierra: 

 REED; Pto Frances (CjUENSEL 1908); V. Colonial (SICOTTSB. 1908). — 

 Centr. Chile. 



116. Galinsoga parviflora Cav. — Johow 1. c. 53. — Masatierra: 

 Germain. — *Masafuera: B. Tolten, a small hispid specimen (no. 469). — 

 Also in Chile. 



117. Amblyopappus pusillus Hook, et Arn. — Johow 1. c. 53. — 

 Masatierra: B. del Padre, especially on the Puente (no. 290); west parts of 

 the island (JOHOW). — Santa Clara: JOHOW; Morro de los Alelies (JOHOW, 

 SKOTTSB.). — Peru — Chile. In Stud. 29 I listed this among the indigenous 

 species. JOHOW supposed that it had been accidentally introduced, and I now 

 agree with him. It is hardly probable that a plant, so numerous in places and 

 quite conspicuous on account of the barren soil, should not have been collected 

 before JoHOW. Known in Chile for its medicinal properties, and perhaps inten- 

 tionally introduced to the islands. 



118. Bahia ambrosioides Lag. — Johow 1. c. 52. — Masafuera: 

 Entrance to Q. de las Casas, extending a few hundred meters to the north and 

 a little to the south of this place (Guajardo, Johow, Skottsb. no. 443). 

 The limited distribution of this species, confined to a place where almost every 

 visitor lands (if he is able to), makes me believe that it was introduced with 

 the traffic. It is also noteworthy that Bahia is not in Germain's collection. 

 Still, there is perhaps as much reason to call it indigenous. — N. and Centr. Chile. 



*I 19. Anthem is cotula L. — Masatierra: B. Cumberland, between 

 stones on the shore (no. 143). — Masafuera? no material preserved. — Also 

 in Chile. 



*I20. Cotula australis Hook. fil. — Masatierra: B. Cumberland 

 (Fcentes, April 191 1, Herb. Santiago!). — Masafuera: Q. de las Casas 

 (no. 1231). — Widespread, also in Chile. 



*I2I. Senecio vulgaris L. — Masatierra: Q. Salsipuedes (no. 631). — 

 Masafuera: Q. de las Casas, in the settlement (no. 419). — Also in Chile. 



*I22. Cirsium lanceolatum (L.) Scop. — Masafuera: El Papal, near 

 the old huts. — Also in Chile. 



*I23. Cynara cardunculus L. — Masafuera: the abandoned village of 

 Las Chozas. — Also in Chile. 



124. Silybum Marianum Gaertn. — Johow 1. c. 64. — Masatierra: 

 DOUGLAS etc. Very abundant in the bottom of valleys from Pto Frances to 



15 — 20100. The Nat. Hist, of Juan Fernandez and Easter Isl. Vol. II.
