basi nunc snbcordatis ; spicis laxiusculis ; sepalis 4 spatliulatis, uno 

 sa3pius obovato multo majore ; corolla parva (vis nltra lin. 2 loiiga 

 alba vel purpurascente) ; staminibus styloque inclusis. — Moist and 

 shady grounds, Lake Co. and northward in California, V. Rattan, 

 June, 1884, Airs. Layne-Curran, July, 1884. Grant's Pass, S. Oregon, 

 Howell. Seeds barely half the size of those of P. malvcBfolia, with 

 inner angle acute but less carinate, and the converging sides plane. 

 Tliis was separately discovered by three collectors nearly at the same 

 time ; but it first came to hand from Mr. Rattan. 



PiiACELiA INVKNUSTA. Eupliacella , P. crenulotce quoad folia sub- 

 similis, hand graveolens, semi- vel sub-pedalis ; foliis omnibus petiolatis 

 oblongis obtusissimis crenato- vel sinuato-paucilobatis nunc lyrato- 

 pinnatifidis adpresso-puberulis ; cymis viscidulo-glandulosis absque 

 pilis setiformibus ; floribus parvulis ; sepalis sursum jjarum dilatatis ; 

 corollis lin. 2 longis ; staminibus styloque inclusis; capsula globosa; 

 semiuibus ovalibus marginibus incurvis carinaque demum tuberculato- 

 rugosis. — Arizona, on Patagonia Mountains, 1880, Lemmon (84, 161), 

 and near Flagstaff, Lemmon, 1884; also near Tucson, Pringle, 1884, 

 along with P. crenulata. The latter is unpleasantly scented (which 

 this is not) and has much larger flowers, with well-exserted stamens 

 and style and usually hirsute pubescence. P. ccerulea, Greene, also 

 of Arizona, is the nearest to P. invenusta. 



Phacelia Popei, Torr. & Gray, is a good species, as distinct from 

 P. glandidosa, under which name it has recently been distributed by 

 A. H. Curtiss (no. 2128). It has short-oval and more pitted seeds, 

 the edges of the pits muriculate-toothed, therefore rougher. 



Phacelia Arizonica, Grav. To this no. loSO of C. "VYriijht's 

 Arizona and New Mexican collection appears to belong. 



Phacelia (Eutoca) Lyoni. Viscido-pubescens ; caule pedali sat 

 robusto ; foliis et inflorescentia fere P. glandidoscc ; corolla lato-cam- 

 panulata, appendicibus semi-ovalibus ima basi filamentis suis accreti& ; 

 genitalibus baud exsertis ; capsula angusto-oblonga polysperma sepalis 

 lineari-spathulatis hispidis et viscosis paullo breviore ; seminibus ovali- 

 bus (paullo ultra semilineani longis) scrobiculatis. — Island of Santa 

 Catalina off Los Angeles, California, W. S. Lyon, 1884. — This is 

 most nearly related to the following, of which a long description has 

 been published, but which still needs a diagnostic character. 



Phacelia ixodes, Kellogg in Bull. Calif. Acad. i. G. Undique 

 viscido-villosa, graveolens, procera; foliis amplis pinnatipartitis nunc 

 pinnatifidis, segmentis lobisve oblongis inciso-dentatis vel sinuato- 

 pinnatifidis ; corolla (cajrulescente) lato campanulata, lobis latissimis
