erous valves, or sometimes falling away. 
2 PHACELIA Juss. Gen. 127. 
Annual or perennial herbs with alternate simple or compound 
leaves, and more or less scorpioid cymes, or so called spikes or 
racemes, of blue purple or white flowers Calyx-lobes all similar 
or nearly so, more or less enlarging in fruit, deciduous, at least 
thrown off by the enlarging capsule, except in P. sericea; the tube 
with or sometimes without appendages within: these when present 
generally in the form of 10 vertical folds or lamellar projections in 
pairs either adnate to or free from and alternate with the base of 
the slender filaments. Stamens equally inserted low down on the 
corolla. Ovules and seeds when reduced to a pair collateral and 
nearly as long as the cell. Seed-coat reticulated or pitted. 
§ EupHacetia B. & H. Gen, ii, 818. Lobes of the campanu- 
late corolla entire ; the tube with 10 laminate appendages in pairs 
at the base of the stamens. Ovules a pair to each placenta. 
Seeds as many as ovules, or by abortion fewer, areolate-reticulate 
or favose. 
* Lower leaves and all the branches opposite: spikes or branches 
of the cyme hardly at all scorpioid: pedicels shorter than the calyx. 
P. Pringlei Gray Pre. Am. Acad xvii, 223. Stem slender, 2-6inches 
high from an annual root, glandular and pubescent : leaves linear-lanceolate, 
entire, tapering at,base, obscurely petioled, only the uppermost alternate: 
calyx-lobes linear, 3 lines long, about half as long as the very open-cam- 
panulate blue corolla, longer than the globose capsule: seeds angled and 
not hollowed ventrally. On the mountains of southern Oregon and north- 
ern California. 
* Pubescence or some of it hispid or hirsute: spikes or branches of 
the cyme scorpioid and dense: pedicels short or hardly any: appen- 
dages of the corolla broad and salient, usually more or less united at 
the base of the filaments. 
+ Leaves all simple and entire, or some of the lower pinnately 
3-5-parted or divided; the segments or leaflets entire: capsule ovate, 
acute: seeds densely alveolate-punctate, the upper end acutish. 
P. nemoralis Greene Pitt. i, 141. Perennial, often flowering the first 
year from seed, 2-6 feet high stout, loosely branching; hispid throughout 
and destitute of canescent pubescence: leaves simple and entire or the 
lower ones more or less lobed or parted at the base, ovate-oblong, 2-6 
inches long, petiolate, rugose and without conspicuous parallel veins; ra- 
cemes geminate, short and spreading, slender but not loose: corolla small, 
greenish-yellow: stamens exserted: fruiting calyx round-ovate or nearly 
globose; the oblanceolate calyx-lobes spreading away from the capsule be- 
low, connivent over it above: seeds 2, (the other 2 ovules always abortive, ) 
ovate, acutish, deeply pitted, dark brown. In rich alluvial soil, Washing- 
ton to Californ‘a. 
P. mutabilis Greene Erythea iv, 55. ‘‘ Biennial, erect, slender, 10 
to 18 inches high, not much branched, sparingly leafy, the radical leaves 
few and ascending, not forming a depressed tuft, sparsely hirsute through- 
out, and with a short somewhat villous pubescence beneath the hirsute: 
leaves of thin texture, mostly entire and simple, elliptic, acute, some of 
the radical with a pair of pinne at the summit of tLe slender petiole: ra-
