DECA.NDRIA. MONOGYNIA. 279 



J^loJea; in E. campanvlata, the stamina are usually 9 to 

 12, the capsule membranaceous, in an early slate by the 

 inflection of the marg'ins of the valves 3-ceiied, at length 

 on opening- resolving- into a sing-le cell with 3 parietal se- 

 miniferous marg-ins, the seeds are in many respects simi- 

 lar to those of DionjEUj and Brosera, both in relative si- 

 tuation and form. The discrepancy consists then princi- 

 pally, in the disunion of the filaments at the base, 2dly, 

 in the absence of valves, and Sdly, in the central and sepa- 

 rate situation of the receptacle. Ihe importance of the 

 iirst of these objections is removed by the example of Sa- 

 rothra inseparable from this order, in whicli iliere is also a 

 capsule of a single ceil, many species oi Hiipericum have 

 also separated stamina; tlie second and third objections ap- 

 pear of conbiderahle importance, and operate also against 

 uniting Dioncea with Drosera, not.vithstandmg their other 

 affinities and the additional f)ne of a simple style, tiiough 

 deeply and divaricately divided, v/hich we liave found in 

 the genus Dioaera. — The limits of this little woric v.'i]l net 

 admit of extended discussions; and v/e siiall noAV merely 

 suggest that these plants, if not actually incorporated wilii 

 the Hypericina, ought to form a proximate order. 



397. JUSSIEUA. L. 



Calix 4 or 5-parted, superior, persistent. 

 Petals 4 or 5, ovate. Capsule 4 or 5-celied, 4 

 or 5-vaIved, oblong, cylindric or angular, ma- 

 nyseeded, crowned by the calix; septa medial. 

 Seeds numerous and minute attached to an an- 

 gular axis. (Stamina 8 or 10.) 



Herbaceous; leaves alternate; flowers solitary, axillary. 

 Distinguished from CEnothera principally by the persis- 

 tence of the calix, and from Lnd~Mgia by the form of the 

 capsule and number of stamens. 



Species. \. 5. gramliji'jra. Herbaceous and aquatic. 

 Flowers conspicuously pedunculate, germ bibracteolate at 

 the base; flowers equal to (Eiiothe'^a fruticosa. 2. erccta- 

 3. subacaiiliSf Ph. 4. *leptocarpa. Annual; ei-ect; stem and 

 calix partly hirsute; leaves lanceolate subglabrous atten- 

 uated at both extremities; flowers sessile 5 or 6 pctalledi 

 capsule slender and cylindric. Hab. On the Missisippi 

 and Missouri, copious; not aquatic. Allied to J. pubes- 

 cens, but smooth except the stem, which is nearly simple 

 about a foot high and irregularly angular; leaves about 2 

 inches, attenuated, but sometimes obtuse; germ c;Uii-
