ONAGRACEAE. 



2. Raimannia laciniata (Hill.) 

 Rose. Sinuate-leaved Evening- 

 primrose. (Eig. 289.) Decumbent 

 or ascending, sometimes branched, 

 4'— 20' high, glabrous or sparingly 

 hirsute-pubescent. Leaves oval-lan- 

 ceolate, oblong, or oblanceolate, acute 

 or obtusish at the apex, sinuate-dentate 

 or often pinnatifid, l'-2' long; flow- 

 ers axillary (or on small plants some- 

 times solitary and terminal), 6"-15" 

 broad; calyx-lobes reflexed; capsule 

 linear, I'-IJ' long, more or less pu- 

 bescent ; seeds strongly pitted. [Oeno- 

 thera laciniata Hill; Oenothera sinu- 

 ata L. ; Oenothera sinuata hirsuta of 

 Moore.] 



Frequent in sandy fields near the 

 South Shores, and in cultivated lands 

 on St. David's Island. Native. Eastern 

 United States. Flowers in spring and 

 summer. The seeds of this and the pre- 

 ceding species were, presumably, brought 

 from the continent by birds. 



Reade records one of the true Evening-primroses, under the name Oeno- 

 thera longiflora, as not uncommon in waste land as an escape from cultivation, 

 prior to 1883, and Lefroy also records a plant under this name, and another 

 as Oenothera biennis. The genus Oenothera differs from Raimannia in habit 

 and by having prismatic-angled seeds. None of its species have been found 

 wild in Bermuda by recent collectors. 



Oenothera Lamarckiana Ser., Lamarck's Evening Primrose, a tall herb 

 with bright yellow flowers up to 4' broad, opening at dusk has, it is said, been 

 grown in gardens. Reade 's description of the plant observed by him might 

 apply to this kind, and H. B. Small's record of Oenothera longiflora points to 

 the same plant. 



3. HARTMANNIA Spach. 



Annual or perennial herbs with branched stems. Leaves alternate, com- 

 monly pinnatifid or lyrate; buds drooping. Flowers white, red, or purple, 

 diurnal, in terminal spikes or racemes. Calyx-tube funnelform. Ovary elon- 

 gated; ovules numerous on slender stalks, in many rows. Capsules club- 

 shaped, 4-winged. Seeds not tuberculate. [In honor of Emanuel Hartmann, 

 a resident of Louisiana.] About 10 species, natives of America. Type species: 

 Eartmannia faux-gaura Spach.
