Note on variation. — A species complex composed of continuous variables, yet Nemophila 

 menziesii is variable only within the limits of a fairly definite pattern as to the main species mass. 

 Variation in the size of the flower (often evidently ecological), variation in color, variation in 

 habit — these variations may be grasped. Although the eccentricities of leaf size and lobation are 

 often extreme in a single colony or even on one individual, such colonies seem undoubtedly of one 

 genetic constitution and leaf variation of a certain bias is thus readily accepted as a natural 

 expression in this species aggregate. All the forms here indicated as varieties are, however, con- 

 nected by obvious intergrades with the species. They are described as follows: 



Var. atomaria Chandler. More succulent and less pubescent; flowers usually fewer; calyx- 

 lobes shorter and broader; corolla white or pale blue, with radiating lines of black or purple dots, 

 somewhat more deeply divided, hairy at center, 6 to 10 lines wide; scales very narrow or linear, 

 usually hairy, often reduced to a mere line of hairs. — Moist places, Coast Ranges from the Santa 

 Cruz Mts. to Del Norte Co., near the coast except at the north where ranging east to eastern Men- 

 docino Co. and Trinity Co. North to Oregon.

 Tracy 6026; South Fork Mt., Trinity Co., Jepson 16,667; Gasquet, Del Norte Co., E. Van De- 

 venter 70. 



Var. venosa Brand. Corolla with a large purple blotch on each lobe and in throat, the pale 

 blue upper portion of each lobe conspicuously purple-veined. — Moist openly wooded hillslopes, 150 

 to 1000 feet: southern Napa Range (foothills e. of Yountville; Nai^a Soda Sprs.). 



Var. integrlfolla Parish. Stems often lax, trailing; herbage hirsute; leaves more variable 

 than usual in the species but mostly (a) obovate with cuneate base and coarsely 3 or 5-toothed 

 at apex, or (b) elliptic in outline and merely coarsely pinnate-lobed or cleft, or (c) some rarely 

 oblong and entire, or (d) sometimes narrow and sinuately pinnate-divided; corolla blue or white, 

 2 to 4 (or 8) lines wide. — Moist slopes and fiats, 50 to 6000 feet: cismontane and intramontane 

 Southern California from Ventura Co. to San Diego Co.; western and southern Mohave Desert. 

 South to Lower California.
