144 UNITED STAIES AND MEXICAN BOUNDARY. 



wliere they are united to the appendages of the corolla ;" Thurher, MSS. The corolla is pale 

 purple, not *' lutescens?" as Alph. DC. supposed it to he. 



Phacelia (Eutoca) Parryi (n. sp.) : parce hispida, pilis longis patentibus pubescentia viscosa 

 intermixtis ; foliis ovatis grosse inequaliter serratis ; racemis plurifloris foliis multo longioribus ; 

 pedicellis calyce fructifero 2-3-plo longioribus ; lobis caljcis anguste-linearibus corolla ampla 



r 



campanulata cluplo brevioribus ; filamentis basi squamaB coroll(^ adnatis ; placontis 20-25-ovu- 

 latis. Mountains east of San Diego^ California^ June ; Parry. Stem 1-2 feet high, apparently 

 erect. Leaves 1-1^ inch, long^ tapering at the base to a petiole which is 6 or 8 lines long. 

 Eacemes at first circinate, when in fruit nearly a foot long. Pedicels about an inch in length, 

 spreading horizontally. Segments of the calyx a little dilated upward. Corolla two-thirds of 

 an inch in diameter, purplish, the lobes rounded and entire. Stamens scarcely exserted ; the 

 filaments with a small truncate or bidentate adnate scale at the base. Capsule ovate, rather 

 acute, containing about 40 oblong and scabrous seeds. As remarked in the Botany of Parkes' 

 P, R. R. Report, this species seems almost intermediate between Phacelia (Eutoca) and Whitlavia. 

 It has the corolla of the former, with the long pedicels and corolline scales of the latter. 



Phacelia (Eutoca) iNPUNDiBULiFORms (n. sp.) : annua, erecta, hispida, pilis rigidis patentibus 

 pubescentia nigra viscosa intermixtis ; foliis pinnatifidis, segmentis 7-9 inciso-lobatis, lobis 

 obtusis integris vel dentatis ; racemis scorpioideis plerumque bifidis multifloris, floribus congestis 

 brevipedicellatis ; lobis calycinis spathulatis ; corolla semiquinquefida, lobis integris, tubo infun- 

 dihuliformi ; placentis 10-12-ovulatis. Overhanging rock on a mountain near Lake Santa Maria, 

 Chihuahua^ April ; Bigelow^ Wright. Plant 6-8 inches high, somewhat branching from the 

 base. Leaves 1-2 inches long in Bigelow's specimens, somewhat longer in Wright's. Spikes 

 30-^0-flowered, when in fruit 2|-4 inches long; the flowers very closely approximated, on 



in length. (Jalyx hispid and glandularly pubescent, the segments unequal, 

 about two-thirds the length of the corolla, linear-spatulate, obtuse. Corolla pale purple, 2\ 

 lines long, the tube narrower and funnel-form ; lobes rounded. Stamens included, with a pair 

 of oblique folds near the base of each filament. Style 2-cleft about half its length, hairy at the 

 base. Fructiferous calyx nearly the length of the obtuse capsule. Seeds about 20, oval, com- 

 pressed, scabrous, with an elevated ridge on the face. This species is remarkable for its funnel-

a Conanthus of Eutoca {Alph. DC. Prodr.) ; 

 but the habit of the plant is different from that of E. aretioides, Wright's specimens have a 

 laxer habit, as well as larger and more membranaceous leaves than Bigelow's, probably from

having grown in a shady place. 



Phacelia (Eutoca) Douglasii, Eutoca Douglasii, Benih. I. c. ; Alph. JDG.l. c. Sandhills, 

 Danas' Ranch, California, March ; Parry. 



Phacelia mtcba^^tua (n. sp.) : annua, erecta, gracilis, parce glanduloso-pubescens ; foliis 

 pinnatifidis, segmentis 5-9 obovatis obtusis integris vel 1-2-dentatis ; petiolis marginatis basi 

 auriculatis ; racemis simplicibus vel bifidis paucifloris ; calyce pedicello subfequali, segmentis 

 obovato-oblongis obtusissimis, corolla late campanulata calyce vix longiore campanulata; pla- 

 centis 8-12-ovulatis ; seminibus oblongo-cylindricis incurvis transverse valde rugosis. Stony 

 hills, near El Paso, March ; Blgelow. Santa Cruz, near Tubac, Sonora ; Parry. (No. 1582, 

 Wright.) Plant 4-8 inches high, moderately branching. Leaves about an inch in length 

 contracted below to a narrowly winged petiole and then dilated and auriculate at the base- 

 Flowers distant, 1-| line in diameter, the pedicels slender and a little spreading. Calyx some- 

 what enlarged in fruit. Corolla pale purple ; the 10 appendages minute, transversely lunate.
