DECANDRIA. MONOGYNIA. 279 



Ehdea; in E. campanulata, the stamina are usually 9 to 

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

 inflection of the marg-ins of the valves S-celled, at length 

 on opening resolving into a single cell with 3 parietal se- 

 miniferous margins, the seeds are in many respects simi- 

 lar to those of Dionxcy and Drosera, 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 odly, in the central and sepa- 

 rate situation of the receptacle, rhe importance of the 

 first of these objections is removed by the example of iSa- 

 rothra inseparable from this order, in which there is also a 

 capsule of a single cell, many species o^ Hijpericum have 

 also separated stamina; the second and third objections ap- 

 pear of considerable importance, and operate also against 

 imiting Dionxa with Jtrosera, notwithstanding their other 

 affinities and the additional one of a simple style, though 

 deeply and divaricately divided, which we have found in 

 the genus Drosera. — The liniiis of this little work will not 

 admit of extended discussions; and we shall now merely 

 suggest that these plants, if not actually mcorporated with 

 the Hypericina, ought to form a proximate order. 



S97. JUSSIEUA. i. 



Calix 4 or S-parted, superior, persistent. 

 Petals 4 or 5, ovate. Capsule 4 or o-celled, 4 

 or 5-valve(l, 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 (Enothera principally by the persis- 

 tence of the calix, and from Luckuigia by the form of the 

 capsule and number of stamens. 



Species. 1. J. grandiflora. Herbaceous and aquatic. 

 Flowers conspicuously pedunculate, germ bibracteolate at 

 the base; flowers equal to (Enothera fruticosa. 2. erecta. 

 3. subacmdis, Ph. 4. *leptocarpa. Annual; erect; stem and 

 calix partly hirsute; leaves lanceolate subglabrous atten- 

 uated at both extremities; flowers sessile 5 or 6 petalled; 

 . capsule slender and cylindric. Hab. On the Missisippi 

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

 cens, but smooth except the stem, w^hich is nearly simple 

 about a foot high and irregularly angular; leaves about 2 

 inches, attenuated, but sometimes obtuse; germ cylin-
