20. L. orcuttii (Parry & Gray) Jepson. Stem branched from the base, 3 to 

 6 inches high; herbage thinly puberulent; leaf-blades palmately parted, IV2 to 3 

 lines long; flowers in terminal capitate clusters, sometimes in small clusters in the 

 axils or solitary iu the forks; calyx deeply cleft, the lobes membranous-margined, 

 3 to 4 times as long as the tube, the tube membranous to base below the sinuses ; 

 corolla funuelform, pink-white, 8 to 12 lines long, the tube equaling the calyx, the 

 tliroat Ys to % as long as the tube ; filaments inserted on the base of the corolla- 

 throat and as long, the anthers barely exserted from the throat ; style exceeding the 

 stamens ; capsule oblong, the seeds small. 



Opens on brushy or wooded hillslopes, 3000 to 3500 feet : Palomar Mt., San Diego 

 Co. South to northern Lower California. May-June. 



Field note. — Linanthus orcuttii occurs locally on the northerly slope of Palomar Mt., in the 

 mountain valley called Cootca, where it is a shoivy annual in the latter part of May and early June. 

 It also occurs elsewhere on that mountain. Other stations in California are not kno%vn to us.

21. L. serrulatus Greene. Stem erect, simple or branched, 4 to 8 inches high, 

 puberulent; leaves in few whorls, the blades palmately 5 to 7-parted into linear 

 lobes, the lobes spinulose-ciliate; flowers capitately and terminally congested, occa- 

 sionally a few flowers in the axils of the branches ; calyx mostly chartaceous, not at 

 all or only slightly membranous below the sinuses, its lanceolate or subulate lobes 

 2 to 4 times as long as the calyx-tube ; corolla salverform, white to cream-color, the 

 tube purple, 3 to 5 lines long, pilose-puberulent, the tliroat yellow, often with black 

 markings at base ; corolla-lobes 2I/2 to 4 lines long; filaments inserted about middle 

 of corolla-throat, the anthers barely exserted from the throat; style exceeding the 

 anthers; capsule-cells 1 to 3-seeded. 



Mountain valleys and eaiion slopes, 2000 to 4000 feet : Sierra Nevada from 

 Mariposa Co. to Kern Co. June. 



Field note. — Linanthus serrulatus has been little collected and is known but from few sta- 

 tions: Mariposa, Congdon; Coarsegold, Madera Co., Benson 3582; Big Creek, Fresno Co., I. T. 

 Walker; Eshom Valley, Tulare Co., Jepson 2807; Bear Creek, Tulare Co., Furpus 1737; Laver's 

 Mdw., Greenhorn Mts., Krames. It is closely allied to and perhaps no more than varietally 

 separable from Linanthus androsaceus.

22. L. androsaceus Greene. Shower GrLL\. (Fig. 391.) Stem simple or 

 branched from the base, 3 to 14 inches high, puberulent; leaf-blades palmately di- 

 vided into oblanceolate or linear lobes, commonly ciliate or sometimes puberulent, 

 2 to 12 lines long; flowers in dense heads; bracts few to many; calyx herbaceous, 

 coarsely hairy to glabrous, cleft nearly to base into subulate lobes, not at all mem- 

 branous or only slightly below the sinuses; corolla salverform, white, pink, crimson,
