 EvEN-iNG FniMK<isE. Herbs, or sometimes slirubby at 

 the base, with alternate simple or pinnatiseet leaves and 

 mostly showy fls., which are yellow, white or rose-color: 

 calyx with a tube prolonged beyond the angled or cylin- 

 drical ovary, with 4 usually strongly reflexed lobes; 

 petals 4, mostly obovate or spatulate; stamens 8, with 

 narrow mostly versatile anthers: fruit a 4-valved locu- 

 licidal capsule. The (Enotheras are mostly dry-soil 

 plants and are chietiy North American. Some of them 

 are South American, and Bentham & Hooker admit one 

 plant which grows in Tasmania. The genus is poly- 

 morphous, and there is consequently great difference of 

 opinion as to generic bounds. What is commonly re- 

 garded as one genus is broken up into ten or a dozen 

 genera by some authors. These minor genera are here 

 treated as subgenera, for the group is fairly homoge- 

 neous from the horticultural point of view, and an en- 

 tirely new set of names in several strange genera could 

 scarcely be forced on the trade. The Godetia section 

 c >ntains some excellent tiower-garden plants, and some 

 of the true CEnotheras make glowing displays of yellow 

 in the border; but the greater number of the species 

 are of only secondary importance to the cultivator. 

 Amongst the best of the border-plant species are (E. 

 frittico:>a, var. Youngii, (E. giavca, var. Eraseri, CE. 

 ciespilosri, IE. Missouriensis, (E. speciosa. For a

the latter species. The western type seems not to be in 

 the trade. 



As to culture, most sorts seem to prefer a porous soil 

 with a rather large proportion of sand, an ideal soil 

 consisting largely of decomposed granite with some 

 vegetable matter. They seem to be quite adaptive, and 

 (E. brachycarpa, Missouriensis, etc., are found some- 

 times in stiif clay soil. An abundance of sunshine is 

 natural to most sorts. q jj Andrews.
