NEW PLANTS FROM MEXICO. 



Socorro Island, where it is said to be abundant in places, as a 

 bush 3-4 feet high. Anthon3^'s No. 376. 



Alvordia fruticosa. A much- branched scabrous shrub 1-2 

 meters high; leaves strigose pubescent, ovate-lanceolate, entire, 

 3-nerved, 3-5 cm. long, on petioles 5-8 mm. long; heads 1 cm. 

 long, glomerate at ends of peduncles 3-4 cm. long; involucres nar- 

 row, flatteiied; bracts obtuse, ciliate, about 5, the exterior ones 

 navicular, the inner much longer; flower yellow, solitary in the 

 involucre and rayless; paj)pus of many lanceolate, unequal palefe, 

 sliorter than the 3-mm.-long, flattened akeue. 



San Jacinto, San Jose, and Todos Santos of the Cape Region of 

 Baja California. This plant has been distributed as A. glomerata 

 Brandegee. It is a bush sometimes 6 feet high, much bratiched, 

 and forming clum[)s 4-5 feet in diameter, covered witli yellow 

 flowers at the ends of the branches. The distinctions between 

 herbarium specimens of this species and A. glomerate, are found 

 mainly in the inflorescence. The single flower, the absence of 

 sterile akenes and bracts upon the receptacle, the smaller fruit and 

 different pappus easily distinguish it from the original species. If 

 this species from the Cape had been the one first collected, its rela- 

 tionship would have been somewhat doubtful on account of the 

 absence of receptacular bracts. 



Leptosyne insu'.aris. Herbaceous, diflTusely branched, and 

 spreading; leaves 2^ cm. long or less, once or twice dissected into 

 narrowly-linear divisions; heads small, 5-7 mm. wide, axillary 

 aM<l terminal on peduncles 6-10 cm. long; bracts of the outer 

 involucre linear lanceolate and loose, of the proper involucre ovate 

 or oblong-.acuminate, 4 mm. long; bracts subtending the flowers in 

 the head linear; ray flowers pistillate, yellow, 2-lobed, 5 mm. long; 

 akenes broadly winged, elliptical, smooth; disk akenes narrowly 

 margined. 



The specimens, consisting of branches about 3 dm. long, are 

 fragmentary. It seems to be an herbaceous perennial, though 

 better material is needed to be certain. No hairy ring is found 

 within the corollas. Anthony's No. 394. Socorro Island. 



Cordia Socorrensis. Scurfy pubescent except the inflorescence 

 and upper surface of the leaves; leaves 2-3 cm. long, |— 1 cm. wide, 

 lanceolate, cuneate at base, crenate, rugose, on petioles 2-5 mm.
