solitary) flattened mid hidden betvve:-n its placenta and the valve : leaves twice or 

 even thrice pinnately parted. Eucrypta, Nutt. PI. Gamb. 159. 



B. chrysanthemifolia, Benth. 1. c. Afoot or two high, erect, paniculately branched, 

 more or less hirsute and scabrous : leaves opposite or the uppermost alternate, on short 

 petioles auriculate-dilated at base, finely twice or thrice (or the uppermost once) parted or 

 cleft into small and short lobes : flowers loosely racemose, the short filiform pedicels bract- 

 less : calyx-lobes ovate or broadly oval, about equalling the small striate-nerved capsule, 

 shorter than the open-campanulate corolla : seeds oval; the ordinary ones (2 to 4 maturing) 

 rugosc-tuberculate, terete, discharged upon dehiscence ; a posterior one (or sometimes a pair) 

 enclosed between each valve and the placenta which lines it, meniscoid, smooth, usually 

 rather larger than the others. Eucrypta puntcnlata & E.foliosa, Nutt. 1. c. Phacelia micran- 

 tha, var.? Upinnatifida, Torr. in Ives Colorad. Exped. Bot. 21. California, from Contra 

 Costa Co. to San Diego and to the borders of Arizona. Corolla and fruiting calyx about 

 3 lines in diameter, sometimes smaller. (Islands of Lower Calif.) 



4. DRAPERIA, Torr. (Dedicated to Professor John William Draper of 

 New York, chemist and historian.) A single species. Gray, Proc. Am. Acad. 

 vii. 401, x. 316, & Bot. Calif, i. 505. 



D. systyla, Torr. 1. c. Low and diffuse or decumbent perennial herb, branching from 

 slightly lignescent base, silky-hirsute and somewhat viscid, leafy : leaves all opposite, ovate, 

 entire, pinnately veined, slender-petioled : flowers crowded in a pedunculate terminal once 

 or twice 2-3-fid cyme ; the unilateral spikes or racemes of which slightly elongate in 

 age: sepals narrow-linear: corolla light purplish, 4 or 5 lines long: capsule thin; the oval 

 placental portion usually separating from the dissepiment in dehiscence : seeds oval and 

 angled ; the coat very minutely or obscurely reticulated. Nama systyla, Gray, Proc. Am. 

 Acad. vi. 37. California, ravines and shaded hillsides, along the Sierra Nevada ; first col- 

 lected by Lobb. 



5. PHACELIA, Jnss. (From cpuxel.o^ a cluster or fascicle, alluding to the 

 crowded flowers of the original species.) -- Annual or some few perennial herbs 

 (all American, chiefly N. American) ; with alternate simple or compound leaves, 

 and more or less scorpioid cymes or so-called racemes or spikes. Corolla deciduous 

 (as generally in the order), at least thrown off by the enlarging capsule (ex- 

 cept in P. sericea /), blue, purple or white, never yellow, except the tube of certain 

 species ; the tube with or sometimes without appendages within ; these when 

 present generally in the form of 10 vertical folds or lamellar projections (borne 

 on a lateral vein), in pairs, either adnate to or free from and alternate with the 

 base of the slender filaments. Calyx-lobes commonly narrow, often wider up- 

 wards, more or less enlarging in fruit. Seed-coat reticulated or pitted. Gray, 

 Man. ed. 5, p. 3G9, & Proc. Am. Acad. x. 31(3. Phaceiia, Cosmanthus (Nolte), 

 Eutoca (R. Br.), & Microgenetes, A.DC. Prodr. ix. 292, 297. 



1. EUPHACELIA, Gray. Ovules 4, i.e. a pair to each placenta: seeds as 

 many or by abortion fewer, vertical ; the testa areolate-reticulate or favose : lobes 

 of the campanulate corolla entire (or rarely erose-dentate) ; the tube with 10 lami- 

 nate appendages in pairs at the base of the stamens. -- Phacelia, Juss., A.DC. 



* Lower leaves and all the branches opposite : no hispid or hirsute pubescence : spikes or branches 

 of the cyme hardlv at all scorpioid: pedicels much shorter than the calyx. (An anomalous 

 species.) 



P. namatoides, Gray. Annual, a span high, brachiately branched, glabrous and glau- 

 cous below, above glandular-pubescent : leaves narrowly -lanceolate, entire, tapering at 

 base, obscurely petioled ; only the uppermost alternate, equalling or surpassing the rather 

 loose spikes or branches of the cyme : sepals spatulate-linear, a little shorter than the
