Pericartium, none. The Calyx grows hard and closes at the 



neck. 

 Seeds 2, roundish. 



N. B. The number of stamina exceedingly uncertain; in 

 some flowers 12, sometimes iO, frequently J. In the Agrimo- 

 nia eupatoria the outer calyx adheres to the inner one ; the seeds 

 are 2, the stamina from 12 to 20 ; the fruit surrounded by bris- 

 tles. — Stamina from 5 to 12. 



RESEDA. 



Calyx. Perianthium, 1 leaf, divided ; segments narrow, acute, 

 upright, permanent, 2 of them standing more open on ac- 

 count of the nectariferous petals. 

 Corolla. Peta.'ssevtral, unequal, always some, with 3 shal- 

 low clefts ; the uppermost bulging at the base, as long as the 

 calyx, and containing honey. 

 Nectarium, aflat uprightgland, risingfrom the receptaculum, 

 situated between the stamina and the uttermost petal, clos- 

 ing with the base of the petals, which on that side are 

 dilated. 

 Stamina. Filaments ll to 15, short. Anthene blunt, upright, 



as long as the blossom. 

 Pjstilla. German bulging, ending in some very short styles, 



Stigmata simple. 

 Peri car pi um. Capsula bulging, angular, tapering to the styles, 



with 1 cell, opening between the styles. 

 Seeds many, kidney-shaped, fixed to the angles of the cap- 

 sula. 



N. B. There is hardly any Genus so difficult to characterize 

 as this ; the different species varying so much both in figure 

 and number. The essential character consists in the petals with 

 3 clefts, l petal bearing the nectarium in its base, and the capsular 

 not closed, but always gaping open. In the Reseda luteola the 

 -calyx has 4 divisions, the petals are 3; the uppermost, contain-
