ETENING-PRIMROSE FAMILY. 143 



2. GAURA. (Name in Greek means superb, which these plants are not; 

 only one of them is worth cultivating. ) Fl. all summer. 



G. Lindheimeri, of Texas, cult, for ornament, nearly hardy N., about 

 3 high, hairy, with lanceolate sparingly toothed leaves, long weak branches 

 producing a continued succession of handsome white flowers ; the calyx hairy 

 outside ; petals nearly 1' long. ^ 



G. biennis, the common wild species, 3 -8 high, soft-hairy or downy, 

 with oblong-lanceolate obscurely toothed leaves, small white or flesh-colored 

 flowers, and downy fruit. (2) 



3. EPILOBIUM, WILLOW-HERB. (Name compounded of three ( 

 Greek words, meaning violet on a pod.} Fl. summer. The pods opening 

 give to the winds great numbers of the downy-tufted seeds. ^ 



1. Flowers large and shoioy, in a lung spike or raceme, the widely spreading 

 petals on short claws, the stamens and long style bent downwards, and the 

 stigma of 4 long lobes : leaves alternate. 



E. angustifdlium, GREAT W. or FIRE-WEED. One of the plants that 

 spring up abundantly, everywhere northward, where forests have been newly 

 cleared and the ground burned over: tall (4 -7 high) and simple-stemmed, 

 smooth, with lanceolate leaves, and a long succession of pink-purple flowers. 



2. Flowers small, in corymbs or panicles terminating the branches, with petals, 

 stamens, and style erect, a club-shaped stigma, and ail the lower leaves 

 opposite: stem l-2 high. 



E. COlor^ltum. Almost everywhere in wet places, fl. through late sum- 

 mer and autumn, nearly smooth ; with thin lance-oblong leaves generally with 

 purple veins, and purplish petals deeply notched at the end and a little longer 

 than the calyx. 



E. molle. In bogs N., less common, soft downy all over ; leaves crowded, 

 linear-oblong, blunt ; petals rose-color, notched, 2" -3" long. 



E. pallistre. In wet bogs N., slender, minutely hoary all over ; leaves 

 linear or lance-linear, nearly entire ; petals purplish or white, small. 



4. ZAUSCHNERIA. (Named for Zauschner, a Bohemian botanist.) 11 

 Z. Californica. Cult, for ornament, from California, flowering through 



late summer and autumn, 1 - 2 high, the oval or lanceolate leaves and the pods 

 with downy-tufted seeds resembling those of Epilobium ; but the handsome 

 scarlet flowers more like those of a Fuchsia : these are single and sessile in the 

 axils of the upper and alternate leaves, or at length somewhat racemed, about 

 2' long. 



5. CLARKIA. (Named for Capt. Clark, who with Capt. Lewis made the 

 first official exploration across the mountains to the Pacific, and brought home 

 one of the species.) Herbs of Oregon and California, with alternate mostly 

 entire leaves, and showy flowers in the upper axils, or the upper running 

 into a loose raceme : cult, for ornament : fl. summer. 



C. pulch^lla. About 1 high, with narrow lance-linear leaves, deeply 

 3-lobed petals (purple, with rose-colored and white varieties), bearing a pair of 

 minute teeth low down on the slender claw, the lobes of the stigma broad and 

 petal-like. There is a partly double-flowered variety. 



C. elegans. Fully 2 high, more commonly dowered in the conservatory, 

 with long branches, lance-ovate or oblong leaves, the lower petioled, lilac-purple 

 entire petals broader than long and much shorter than their naked claw, 

 smaller lobes to the stigma, and a hairy ovary and pod. 



6. EUCHARIDIUM. (Name from the Greek, means charming.) 

 E. COncinnum, of California, cult, for ornament; a low and branching 



plant, like a Clarkia in general appearance, except in the long tube to the calyx, 

 and with ovate-oblong entire leaves on slender petioles, and middle-sized rose- 

 purple or white flowers, in summer.
