Perennial herbs with horizontal rootstocks. Leaves alternate or mainly 

 radical, pinnate or pinnately parted, long-petioled. Flowers in capitate cymes. 

 Calyx without appendages. Corolla campanulate, 5-lobed, the tube with a 

 nectar-bearing grooved appendage opposite each lobe. Stamens exserted, the 

 filaments hairy at the middle. Style filiform, exserted. Capsule 1-celled, 

 2-valved, 1 to 4-seeded. (Greek hudor, water, and phullon, leaf.)

 leaflets 9 to 15, incised, the terminal ones not distinct; peduncles generally

 Nevada.

Leaves, especially the upper, sometimes alternate, typically with 5 to 9 suborbicular 

 petiolulate lobes, but very diverse 7. X. exilis. 



1. N. aurita Lindl. Climbing Nemophila. Weak and straggling; stems 

 angled or winged, armed with retrorse prickles which enable it to climb over 

 other plants; petioles broadly winged and auriculate-clasping; corolla violet, 

 paler outside, with a short throat constricted below top, and spreading limb. 



Shady places in Coast Ranges and Sierra Nevada foothills. 



2. N. maculata Benth. Spotted Nemophila. Branches ascending or de- 

 cumbent; leaves pinnately parted into 5 to 9 ovate or suborbicular, mostly 1 

 to 3-lobed divisions, the upper usually with only 3 or 5 entire lobes at tip and

 leaves; corolla white, with rows of purple dots radiating from the center to 

 the purple spot at the end of each lobe; scales half free, rolled toward the

 succulent, ascending, more or less hirsute-pubescent; lower leaves 1% to 3% 

 in. long, pinnately divided into 5 to !> mostly 2 or 3-lobed divisions; upper
