PHACELIA FAMILY 281 



Mum 12,448. All these loosely branched plants have small corollas as in typical P. pachyphylla, 

 but in habit resemble more closely Phacelia calthifolia and are thus different in aspect from the 

 compact dwarfs of the former species. 



Eefs. — Phacelia pachyphylla Gray, Proc. Am. Acad. 19:88 (1883), type loc. Calico Mines, 

 Calico Mts., cent. Mohave Desert, S. B. 4- W. F. Parish; Jepson, Man. 830 (1925). P. neglecta

63. P. calthifolia Brand. Stem stout, erect, commonly branching from the 

 base, 3% to 11 inches high ; herbage densely glandular-pubescent throughout, stain- 

 ing paper brownish in drying; leaves mostly basal or subbasal; leaf -blades sub- 

 orbicular or orbicular-ovate and subcordate, erenate or crenulate, 1 to 2 inches long, 

 the lower long-petioled, the upper almost sessile and nearly opposite, smaller; 

 racemes less densely flowered than in P. pachyphylla, II/2 to 6 inches long, the flow- 

 ers almost sessile; calyx-lobes broadly linear, 2 to 3 lines long, very glandular and 

 often very black; corolla purple, broadly campanulate, 4 to 6 lines long; scales 

 narrow, adnate to coroUa, united below to the base of filament so that the pair makes 

 a pocket behind stamen; stamens unequal, included ; capsule oblong-rotund, equal- 

 ing or slightly exceeding calyx. 



Sandy or gravelly washes or flats or talus slopes, -280 to 2000 feet : Death Valley 

 region, Inyo Co. ; south into the central Mohave Desert. Apr. -May.

64. P. gymnoclada Torr. Stems several from the base, radiately branching, 

 the branches 5 to 9 inches long, decumbent ; herbage hirsutulous ; leaf -blades oblong 

 to elliptic, coarsely erenate, Y2 to 1^/4 inches long, on petioles % to as long ; racemes 

 becoming loose ; calyx-lobes linear, i/o to % the length of corolla ; corolla purple, 

 campanulate, 4 lines long, shallowly lobed (the lobes transversely elliptic) ; stamens 

 V2 as long as corolla; style shortly bifid at apex ; capsule 8 to 16-seeded. 



Sandy foothills, 4000 to 6000 feet : eastern borders of California in Sierra Co. 

 and perhaps Mono Co. East to western Nevada. June. 



Locs. — No precise station for Phacelia gymnoclada is known in California but there is a 

 record of occurrence in Sierra Co. (Engler, Pflzr. 4-''i:129). This species has, in addition, been 

 attributed to Mono Co. and it may occur, since a definite station in the state of Nevada, namely, 

 mouth of Pinchot Creek, White Mts., Esmeralda Co., Duran 3261, lies within a few miles of the 

 Mono County, California, line.

7. MILTITZIA A. DC. 



Annuals, similar to Phacelia. Flowers in racemes, the pedicels during anthesis 

 commonly % to i/^ as long as the flowers. Calyx-lobes linear (or linear-oblauceo- 

 late). Corolla persistent, the scales in its tube very minute. Ovary 2-eelled by 

 meeting of the placentae in the center, the placentae very narrow, borne on half- 

 partitions ; ovules 2 to 8 to each placenta. Style in ours persistent. Capsule ovoid, 

 compressed. — Species 5, western North America. (Friederich von Miltitz of Dres- 

 den, author of a handbook of botanical literature, 1829.) 



Corolla 1% to 2 times as long as calyx; flowers ascending, the pedicels straightish or slightly 

 curved, % to 1% lines long; Lassen Co 1. il. Intea. 



Corolla only slightly exceeding calyx; flowers spreading, the pedicels retrocurved, 1 to 2 lines 

 long ; Inyo Co 2. M. inyoensis. 



1. M. lutea A. DC. Stems several from the base, branching, procumbent or 

 diffuse, 2^4 to 6 inches long ; herbage pubescent, the inflorescence usually slightly
