doubt to Navarretia cotulaefolia or to Navarretia pubescens or indicated as allied to one or the 

 other but different. This material has been segregated by Virginia Bailey and a diagnosis prepared 

 for this unit. It seems to be the same as Navarretia bowmanae Eastw. of Lake County and that 

 name is here tentatively used, although Navarretia bowmanae lies outside the main range of this 

 unit. Navarretia bowmanae rests, as to its type, upon specimens collected at Anderson ranch near 

 Lower Lake in Lake County. For this problem two excellent collections, one in flower and one in 

 fruit, have been made at the type locality by Mabel H. Hazell. The corollas in the Hazell plants are 

 either blue or white. The corollas in the type were described as yellow. In the Sacramento Valley 

 plant the corolla is blue, but in one instance has been observed to change from blue to dull yel- 

 low in drying. As here described, the following stations are cited for collections of Navarretia 

 bowmanae :

 Stem erect, usually branching above, 5 to 18 

 inches high ; herbage puberulent ; leaves % to 2 

 inches long, pinuately divided with the divi- 

 sions pinnatifid or pinuately divided or toothed, 

 terminal portion of the upper leaves less deeply 

 divided or merely laeiniate-toothed, so that the 

 raehis appears as if spatulate-dilated; bracts 

 villous, palmately parted above the broad base, 

 the spinose divisions spinosely pinnatifid or en- 

 tire, the broad base covered outside with a web 

 of villous hairs or subglabrous; basal portion of 

 bracts and calyces white-chartaceous; middle 

 portion of calyces villous, sometimes merely pu- 

 berulent ; calyx-lobes unequal, 3 entire and the 

 2 longer toothed, or all pinuately toothed; co- 

 rolla narrowly funnelform, deep blue (a white 

 line in throat below each sinus, or throat and 

 t times as long as the calyx ; corolla-throat longer 

 than corolla-lobes; stamens esserted, the filaments inserted in base of throat; style 

 2-cleft; capsule 1-celled, 4-valved, dehiscent from below, 1 (or rarely 2) -seeded; 

 cotyledons of the embryo pai'ted into 3 lobes, the divisions so deep as to give the
