180 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 13 



Verbesina oligocephala Jtn., Proc. Calif. Acad. Scl. IV, 12: 

 1200. 1924. 



Canyon above Puerto Escondido, Sierra Giganta, March 13, Rempel 

 164, canyon bottom. 



Known only from the canyons of the Sierra Giganta, southern Baja 

 California; type from mountains back of Agua Verde Bay. Rempel's col- 

 lection is the second. The plant may well be a relic endemic of a Sierra 

 Giganta postinsular locality. Johnston reports it as an erect growing 

 little-branched shrub about 1 m tall. It is distinguished by its rather 

 large triangular, coarsely irregularly serrate to undulate leaves, the to- 

 mentose stem, and the long-pedunculate (2-4 cm) heads with a double 

 series of unlike involucre bracts, the outer of which are broader than 

 the inner and markedly reflexed. 



Viguiera deltoidea chenopodina (Greene) Blake, C.N.H. 54; 

 91. 1918. 



San Pedro Nolasco Island, February 6, Dawson 1033. Island in Con- 

 cepcion Bay, March 16, Rempel 201. 



Middle Baja California and adjacent islands; type from between 

 Santo Domingo and Matancita. 



Although Johnston (I.e. p. 1201) referred his Nolascan collection 

 {3127) to typical Viguiera deltoidea Gray, the present collection with 

 its small, deltoid, entire, strigillose leaves appears to relate the plant to 

 the variety, chenopodina. The flowers and achenes, however, are con- 

 siderably smaller and the leaves larger than Rempel's Concepcion Bay 

 number, which appears typical of the variety. 



Viguiera tomentosa Gray, Proc. Am. Acad. Sci. 5:161. 1861. 



Punta Frailes, February 16, Dawson 1117, 1129. San Jose del Cabo, 

 February 17, Dawson 1169. Cabeza Ballena, Cape District, March 3, 

 Rempel 58. 



Known only from the Cape District of Baja California; the type 

 from Cape San Lucas. A large-leaved and large-flowered shrub.
