Franseria. At Miraflores ihis is the most common Composite- It 

 grows about 10 feet high, with acuminate leaves 6 inches long. It is a 

 bad hay fever plant and abounds from the Cape north on both sides. It 

 gave me a bad cold. 



Franseria Bryanti Brandegee. This rather densely branched shrub is 

 about 2 feet high, shrubby below. Was in full bloom January 31, 1928, 

 at Todos Santos. It produced an enormous amount of pollen with a very 

 strong odor that readily caused hay fever reactions. 



Viguieria deltoides Gray. Shrubs allied to E. albescens; 8-10 feet 

 high, tufted at base, with slender stems branching widely and gray- 

 barked, forming an open and rounded outline, decidedly taller than the 

 usual Encelia, wi^ black, center. Upper side of leaves shining and green, 

 appearing as if smooth but really very rough with very short and stiff 

 white hairs from a pustulate base but the hairs sparsely scattered, with 

 veinlets rather impressed. The lower side of leaves lighter colored, and 

 with rather more hairs somewhat longer and becoming hispid on the veins 

 and nerves, but still very short, with veins and veinlets raised into sharp 

 ridges. Leaves rhomboidal-ovate, obtuse, entire and with slightly revo- 

 lute margins, 2-3 inches long by l.S-2 inches wide, leathery, deltoid- 

 cuneate below into a stout petiole about 4 mm. long, opposite, 3-ner\-ed 

 from the base. Intemodes 2-4 times as long as the leaves. Inflorescence 

 terminal, rather corymbiform (but really racemose), witji single heads m 

 the axils of reduced leaves below and on long peduncles, and the upper 

 htads on shorter peduncles which are subtended by mere bracts. Heads 

 with yellow disk flowers, and disk rather hemispherical. Heads 5-10 mm. 

 wide and long. The ashy bracts linear, acutish, not over 1 cm. long, the 

 outer ones rather spreading, all ashy but smoother at tip, and rough witn
