20 PITTONIA. 
++ ++ Corolla small, as in most species. 
17. A. CALIFORNICA. Slender, sparingly setose, diffusely 
branching, the branches 6—15 inches long, weak and reclining: 
racemes with few bracts at base: calyx-segments slender, not 
accrescent, spreading in fruit: nutlet ovate, 2-line long, keeled 
and rugulose and granulated as in the last; scar roundish, 
nearly basal.— M yosotis Californica, Fisch. & Mey. Ind. Sem. 
Petrop. 1835: Eritrichium Californicum, DC. l. c., Gray l. c. 
excl. var. and also Krynitzkia. 
Common in the central and northern parts of the State, 
from the éoast to the foot-hills of the Sierra Nevada ; when 
in flower only rather hard to distinguish from the more slen- 
der forms of A. stipitata. 
* * Perennial ; soft to the touch, the dense pubescence villous. 
18. A. MOLLIS — Eritrichium molle, Gray, Proc. Am. Acad. 
xix. 89; Krynizkia, Gray l. c. 
Sierra Nevada, where it has been collected only by Mr. 
Lemmon. ; The plant from near Visalia, described as rougher 
in its pubescence, is not known to us. 
PLAGIOBOTHRYS, Fisch. & Mey. 
Racemes spike-like, elongated, loose, naked or leafy- 
bracted ; pedicels very short, filiform, persistent. Calyx 5- 
cleft or -parted, closed or campanulate, or even stellate- 
spreading and more or less accrescent in fruit, when not too 
deeply cleft irregularly circumscissile near the base. Nutlets 
ovate or indistinctly eruciform in outline, carinate on both 
sides toward the apex, usually with well defined lateral mar- 
gins, the back very regularly transversely rugose, smooth or 
roughened between the rugs ; insertion almost medial on a 
depressed gynobase: areola or scar rounded, hollow or solid, 
not rarely stipitate. Rather large but slender annuals with 
most of their leaves in a close radical tuft, the elongated
