red, throat very short and broad, yellow, lobes two lines long,

La Graciosa, Santa Barbara Co., and also San Luis Obispo 

 Co., Alice Eastwood, 1896. The former the type; both specimens 

 in the California Academy of Sciences Herbarium. 



26. Linanthus serrulatus Greene. 



Annual, four to five inches high, with many diverging 

 ascending branches, stems puberulent, internodes not much 

 exceeding one inch, leaves and bracts with very narrow, linear, 

 acerose segments, cuspidate-tipped, glabrous except the margins 

 which are not at all white-ciliate, but are closely slender- spiuose- 

 toothed; inflorescence of comparatively small clusters, not a 

 compact head as in L. ciliatus and near relatives, therefore the 

 individual calyces are in greater evidence; calyx five lines long, 

 tube one line, this and the lower part of the lobes coriaceous, 

 lobes acerose, subulate, sometimes slightly recurved; corolla 

 about one inch long, tube slender, red, limb two lines long, lobes 

 one and one-half lines, white to lavender; stamens shorter than 

 the lobes, anthers nearly round, stigma about equal to the sta- 

 mens; capsule oblong, three lines long. 



Madera, California, Mr. Buckminster, May, 1889, seen in the 

 California Academy of Sciences Herbarium and probably the type. 



27. Linanthus acicularis Greene. 



Small annual, two to four inches high, simple or branched; 

 short white pubescence on the stem and corolla tube, hirsute 

 pubescence on the leaves; leaves one-fourth inch long, lower 

 ones shorter, three-parted, segments acerose, stiff; inflorescence 

 of small terminal heads; calyx about two and one-half lines long, 

 narrow, acerose teeth longer than the tube; corolla light yellow 

 throughout or with darker throat, tube very slender, about three 

 times the limb, the whole less than one inch in length; stamens 

 about equalling the lobes, anthers oval; style short, three stigma 

 segments not equalling the stamens.
