DOWNINGIA Torrey. 
_ Glabrous annual herbs with sessile narrow leaves, the upper 
ones reduced to bracts, and axillary sessile flowers. Calyx-tube 
and adnate ovary very long and slender, 3-sided, usually twisted, 
its limb divided down to the ovary into five foliaceous lobes. 
Corolla with very short but entire tube and bilabiate limb; the 
smaller lip of two narrow recurved or spreading divisions, the 
other very broad and 3-lobed. Filaments and anthers both uni- 
ted into a somewhat curved tube; two of the latter bristle-tipped. 
Capsule very long and slender, early becoming 1-celled, with two 
filiform parietal placentae. remaining closed at the tip but the 
sides dehiscing by 1-3 long fissures. | 
B. elegans Greene Pitt. ii, 126. Downingia elegans Torrey. Stem 
simple or diffusely branched, 4-12 inches high: leaves ovate to lanceolate, 
acute, 3-15 lines long: calyx-lobes linear-lanceolate, 6-9 lines long: larger 
lip of the corolla 3-lobed, the lobes acute or acutish the other lobes lanceo- 
late: capsule often two inches or more long: seeds short-oblong. In wet 
ground, Brit. Columbia to southern Oregon and Idaho. 
B. pulchella Greene 1c. Downingia pulchella Torrey, ‘‘ Mostly low- 
ér or weaker-stemmed: leaves more linear and obtuse: large lip of the 
corolla deeply 3-lobed; the other two lobes oblong-ovate: seeds elongated- 
oblong. Wet banks, Oregon to California and Nevada ”’ 
OrperR LIII, CAMPANULACEZ Juss. Gen. 163.; 
Herbs, rarely shrubs or trees, with bland milky juice, alter- 
nate simple leaves without stipules, regular 5-merous flowers, 
and 2-5-celled many-seeded capsules or berries. Calyx-tube 
adnate to the ovary; its 5-lobed persistent limb usually divided 
down to the ovary. Corolla valvate, induplicate or rarely im- 
_ bricate in the bud, inserted on the calyx just where it becomes 
free from the ovary. Stamens inserted with the corolla and 
free or adnate at base: anthers with two parallel cells. Style 
one, almost always pubescent or puberulent for some distance 
below the 2-5 introrse stigmas. Ovules anatropous, on pla- 
centae projecting from the axis. Seeds small, usually smooth. 
Embryo straight, in the axis of fleshy albumen. ae 
* Ovary and capsule long.and narrow, or-at least oblong. 
1 Githopsis Capsule opening at, the top by a hole left by the falling 
away of the base of the style between the long calyx-lobes. 
2 Legouzia Capsule opening on the sides by 2 or 3 little valves which 
leave small round perforations. -
