and nearly the capsule and seeds of Lobeliaceje ; the free stamens of Good- 

 ENOViE^, though of a very different character, and with a stigma without 

 indusium, nearly as in the Cyphiaceje, but the corolla gamosepalus, and di- 

 vested of tube. 



Order CAMPANULACE^. (Decand.) 



Heterocodon. 



Calyx foliaceous, five-cleft, or by abortion three or four-cleft, the adnate tube 

 roundish and turbinate. Corolla campanulate, five-lobed, in the lower 

 flowers wanting or minute stamina, five, free, shorter than the anthers. 

 Stigmas three, short. Capsule roundish, membranaceous, with salient 

 angles; three-celled, dehiscing irregularly at the base. Seeds compressed, 

 triquetrous, even. A slender, divaricately-branching annual of Oregon, 

 scattered with almost retrorse, flat hairs, with the aspect of Campanula 

 perfoliata. Leaves alternate, short, roundish, toothed and amplexicaule. 

 Flowers solitary, sessile, the terminal ones only perfectly corolliferous. 

 Corolla strictly campanulate, blue, and small, the stigma and style included. 

 (The name alludes to the unequal character of the flower.) 



Heterocodon ^ rariflorum.Q 



Ha.b. Grassy plains of the Wahlamet and Oregon. Root very small, with a few simple fibres. 

 The plant six to twelve inches high, slender, with few branches, often wholly simple; the stem 

 angular, and pilose. Leaves numerous on the lower part of the stem, roundish-cordate, elegantly 

 and very equally dentate, amplexicaule. Flowers solitary, axillary. Segments of the calyx folia- 

 ceous, wide and somewhat toothed; in the lower subapetalous flowers only three or four-cleft. 

 Corolla about the size and form of that of Campanula hederacea, segments acute. This plant 

 appears intermediate in genus between Campanula and Dysmicodon. 



DYSMICODON, as a section of Specularia, Endlicher. Gen. Plant, p. 5] 8. 



Triodallus. {Rajinesque.) 



Calyx in the upper flowers five-cleft, in the lower imperfect, or apetalous ones 



three or four-cleft, the adnate tube cylindric-obconic, compressed, even and 



without prominent angles. Corolla pelviform, five-lobed. Stamens five, 



free, filaments smooth, not dilated at base, much shorter than the anthers.
