Family 40. CAMPANULACEAE Juss. Gen. 163. 1789. 



Bell-flower Family. 



Herbs (some tropical species shrubs or even trees), with alternate exstipu- 

 late entire dentate or rarely lobed leaves, acrid and usually milky juice, and 

 racemose spicate paniculate or solitary perfect flowers. Calyx-tube adnate to 

 the ovary, its limb mostly 5-lobed or 5-parted, the lobes equal or slightly un- 

 equal, valvate or imbricate in the bud, commonly persistent. Corolla gamo- 

 petalous, regular or irregular, inserted at the line where the calyx becomes 

 free from the ovary, its tube entire, or deeply cleft on one side, its limb 5-lobed, 

 regular, or more or less 2-lipped, or corolla rarely divided into separate petals. 

 Stamens 5, alternate with the corolla-lobes, inserted with the corolla; filaments 

 separate or connate; anthers 2-celled, introrse, separate, or united into a ring or 

 tube. Ovary 2-5-celled (rarely 6-10-celled), with the placentae projecting from 

 the axis, or i-celled with two parietal placentae ; style simple ; stigma mostly 

 2-5-lobed, pilose by a tuft or ring of hairs, or glabrous; ovules anatropous. 

 Fruit a capsule or berry. Seeds very numerous and small; embryo minute, 

 straight ; endosperm fleshy. 



About 60 genera and 1500 species, of wide geographic distribution. 

 Corolla regular, campanulate or rotate: anthers separate. 



Corolla campanulate, rarely rotate; flowers all complete. 



Corolla rotate; earlier flowers cleistogamous. 

 Corolla irregular; anthers connate around the style.

2. Legouzia. 



3. Lobelia. 



i. CAMPANULA L. Sp. PI. 163. 1753. 



Perennial or annual herbs, with alternate or basal leaves. Flowers large or small, soli- 

 tary, racemose, paniculate, or glomerate, regular, complete, blue, violet, or white. Calyx- 

 tube hemispheric, turbinate, obovoid, or prismatic, adnate to the ovary, the limb deeply 5- 

 lobed or 5-parted (rarely 3-4-parted). Corolla campanulate or rotate, 5-lobed or 5-parted. 

 Stamens 5, free from the corolla; filaments usually dilated at the base; anthers separate. 

 Ovary inferior, 3-5-celled; stigma 3-5-lobed. Capsule wholly or partly inferior, crowned by 

 the persistent calyx-lobes, opening on the sides, either near the top, middle or bottom by 

 3-5 small valves or perforations, or tending to be indehiscent in some species. [Diminutive 

 of the Latin campana, a bell.] 



About 250 species, natives of the northern hemisphere. Besides the following, some 8 others 

 occur in the southern and western parts of North America; all known as Bell-flower.
