Onagrariecz Epilobium. 



ordinary wild one in its larger flowers and shorter seed-vessels. 

 There is also a good white variety. 



2. ZAUSCHNfiRIA. 



A genus of one herbaceous species having the same 

 quaternary structure of the flowers and plumose seeds as 

 Epilobium, but the calyx is coloured, and the tube prolonged 

 above the ovary. A commemorative name. 



1. Z. Californica. A much-branched dwarf plant bearing 

 sessile linear -lanceolate pubescent leaves and axillary solitary 

 sessile scarlet ftowers with a long slender projecting style, 

 resembling those of a Fuchsia. It is a native of California, 

 flowering in June. 



3. CLARKIA. 



Elegant slender branching annual plants with linear or 

 lanceolate leaves and solitary or racemose flowers. Parts of 

 the flower in fours. Petals clawed, often deeply 3-lobed. 



Capsule linear, many-seeded ; seeds 

 neither plumose nor winged. Only 

 four species are known, all from 

 North-west America. Named after 

 Captain Clark, a traveller. 



1. G. pulchella (fig. 105). This 

 grows from 18 inches to 2 feet high, 

 with glabrescent linear leaves and 

 large flowers having deeply trilo- 

 bate petals with a pair of small op- 

 posite teeth on the claws. Under 

 cultivation this has given birth to 

 a double variety, and the flowers 

 vaxy in colour from lilac-purple to 

 white. There is also a variety with 

 entire petals. 



2. C. elegans. A rather smaller 

 flowered species. Leaves lanceolate, 

 dentate. Petals entire, without 

 teeth on the claw. 



C. gauroides, syn. C. rhomboldea, 

 is a less attractive species with smaller purplish flowers.
