Tube of calyx adnate to the ovarium the whole length (f. 93. 

 a.), or only adhering to it at the base (f. 94. a.), and drawn out 

 beyond the ovarium at the apex (f. 94. a.) ; limb 2-4-lobed, 

 but usually 4-lobed (f. 93. a. f. 94. a. f. 96. a. f. 98. a.); lobes 

 valvate in aestivation. Petals equal in number to the lobes of 

 the calyx (f. 95. b. f. 96. b. f. 97. b. f. 98. </.), and alternating 

 with them, for the most part regular, twisted in aestivation, in- 

 serted in the top of the tube of the calyx (f. 95. b. f. 96. b. f. 

 97. b. f. 98. </.), rarely wanting. Stamens sometimes equal in 

 number to the petals (f. 93. d. f. 99. e.\ but usually twice that 

 number (f. 95. 6.) ; filaments free, filiform ; anthers oblong or 

 ovate. Ovary many-celled, usually crowned by a cup-shaped 

 gland. Style filiform. Stigma capitate (f. 95. c.) or lobed (f. 

 96. c. f. 97. a.). Fruit capsular (f. 96. d. f. 99./.), baccate 

 or drupaceous, 2 or 4-celled. Seeds many in each cell, rarely 

 solitary, fixed to the central placenta. Albumen wanting, 

 but the endopleura is sometimes tumid, and appearing like albu- 

 men. Embryo straight, with a long terete radicle and 2 short 

 cotyledons. Herbs or shrubs. Leaves simple, alternate or op- 

 posite, entire, toothed, or pinnatifid, feather-nerved. Flowers 

 axillary, and disposed in terminal spikes or racemes. 



This order is distinguished from Lythrariece in the calyx 

 being adnate to the ovarium, and from Haloragieae in the style 

 being filiform, in the seeds being exalbuminous, and never pen- 

 dulous in the cells. It is also distinguished from Myrtaceee in 

 the leaves being destitute of pellucid dots, in the stamens being 

 definite in number, not indefinite ; and from Lodsece in the seeds 

 being fixed to the central column, not parietal, as in that order. 

 The order is generally known by its pollen cohering by a kind 



of filamentose substance, an inferior polyspermous ovarium, a 

 tetrasepalous tetrapetalous flower, with a definite number of 

 stamens, and a single style ; from this form, however, there are 

 some anomalous variations, such as Circte'a and Lopezia, which 

 are however easily reconciled to the usual structure of the order. 

 Most of the genera are pre-eminently beautiful, as Epilbbium, 

 CEnothera, and Fuchsia, which are old favourites among gar- 

 deners. 



The properties of Onagrarice are but little known. The 

 leaves of Jussieea Peruviana are used as an emollient poultice, 

 and the root of CEnothera biennis as a sort of salad. The valves 

 and dry capsule of CEnothera telraptera contract when the at- 

 mosphere is dry, but when moist they expand.
