 gularia rubra, Tott. Pacif. R. Rep. iv. 70. — California, chiefly on or near the coast. A 

 polymorphous species, the varieties of which, although diverse in aspect, appear in a large 

 series of specimens to be thoroughly connected by intermediates. 



Var. leucantha, Robinson, 1. c. Erect or nearly so, more slender, with long inter- 

 nodes : leaves somewhat narrower and more erect than in the type : floral bracts reduced 

 and inflorescence more distinctly cymose ; pedicels elongated, slender, rather rigidly spread-

Var. scariosa, Robinson, 1. c. Low, pale, smoothish near the base, and often very 

 glandular-viscid above, densely leafy ; the internodes scarcely or not at all developed : leaves 

 4 to 6 lines long, acute ; stipules conspicuous, ovate-lanceolate, acuminate, 3 to 5 lines long : 

 inflorescence racemiform ; pedicels not greatly exceeding the calyx : flowers inclining to be 

 smaller and more numerous than iu the type. — Tissa macrotheca, var. scariosa, Britton, Bull.
