 DOWNINGIA Torrey. 



Glabrous annual herbs with sessile narrow leave?, 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. Doivningia 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

ORDER LIII, CAMPANULACE^ 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 

 adnafce 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 . 



* 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.
