solitary) flattened and hidden between its placenta and tlie valve : leaves twice or 

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



"B. ohrysanthemifolia, Benth. 1- c. A foot or two high, erect, paniculately hranched, 

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

 petioles auriculatc-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-campanulatc corolla : seeds oval ; the ordinary ones (2 to 4 maturing) 

 rugose-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 paniculata & E. foUosa, Nutt. 1. c. Phacelia micran- 

 (Aa, var."? lipinnaiiyida, 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. S^styla, Torr. 1. ^. 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 whicli 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. — Xama sijstijla, Gray, Proc. Am. 

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

 lected by Lobb. 



5. PHAC£lLIA, Juss. (From qjaxiXo^; 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 

 jjresent 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,

§ 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. — Pliacelia, Juss., A.DC. 



# Lower leaves and all the branches opposite : no liispid or hirsute pubescence: spikes or branches 

 of the cyme hardly 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 petiolod ; only the uppermost alternate, equalling or surpassing the rather 

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