60 BOTANY OF THE ROUTE. 



two species. On the interior prairies they begin to flower in February, and continue till July, 

 the fruit ripening from May 1 to August. (On summit of Cascade mountains.) 



F. VESCA, Linn. (G.) Certainly grows on the prairies of the interior. 



F. CHILENSIS, Ehrh. (G.) On sandy prairie along the coast. Flowers much larger than the 

 others are, commonly; open in May. Fruit ripe in July, small, but I have not found it more 

 &quot;villous&quot; than the other species; flavor the same. (Steilacoom.) 



RUBUS NUTKANUS, Moc. (G.) Abundant in dry hilly woods, everywhere; May 1. Fruit 

 ripe in July, dry and acid. 



R. LEUCODERMIS, Dougl. Common in dry open grounds, burnt woods, &c. ; May. Fruit ripe 

 in July, like the common &quot;blackcap.&quot; but larger and covered with a white bloom. 



R. SPECTABILIS, Pursh. (G.) In damp, shady places, especially along the coast. The 

 bright purple flowers expand in February to April. Fruit ripe in July; very fine in good 

 situations. 



R. TRIVIALIS, Michx. Not common. Wet, shady woods near Olympia. Flowers in May; 

 much resembles R. hispidus, Pursh. Fruit not seen. Differs from description, in its far 

 northern locality, in its leaves, which are not coriaceous, and in being more villous. &quot; A form 

 very like it occurs in Sonora.&quot; THURBEE. 



RUBUS MACROPETALUS, Dougl. (G.) Common on dry hills, forming prostrate branches, and 

 resembling R. Canadensis, Linn. Fruit very good; June. 



ROSA FRAXINIFOLIA, Bork. (G.) Common in wet ground, everywhere; June 16; 6 feet. 



ROSA GYMNOCARPA, Nutt. On borders of woods in dry soil, (Vancouver and Puget Sound.) 

 Not rare; May 20. Flowers small, dark red, and inodorous. 



PYRUS RIVULARIS, Dougl. Oregon crab -apple. Wet grounds everywhere west of Cascade 

 mountains; April, May. Fruit small, but good; ripe in July. Very useful for grafting on. 



P. AMERICANA, DC. Mountain ash. On higher parts of Cascade mountains; rare. Fruit 

 collected in July, ripe, larger than common, and of a bright orange color. 



AMELANCHIER CANADENSIS, Linn., var., y., Torr. & Gray. Abundant on borders of woods of 

 the interior, but rare along the coast; May. Whole plant larger, and fruit much larger and 

 finer than in New Jersey. &quot; Service berry,&quot; (Steilacoom, S.) 



EPILOBIUM ANGUSTIFOLIUM, Linn. (G.) Exceedingly abundant, especially in the dead forests, 

 where its bright flowers color the surface for miles together in July; flowers from June to 

 October, purple. (Steilacoom, S.) 



E. TETRAGONUM, Linn. (G.) Not uncommon in large prairies near the coast; July. 



E. COLORATUM, Muhl. Abundant in wet grounds everywhere ; June to October. 



E. MINUTUM, Lindl. (G.) Rare on the dry prairies near Steilacoom in shade; June 10; flowers 

 very small, pale purple; plant somewhat decumbent, branching from the base; leaves nearly 

 linear; flowers much smaller than in E. paniculatum, which it seems to resemble much. (S.) 



E. PANICULATUM, Nutt. (G.) With E. coloratum, but less common; June to August. (E. 

 luteum, said to be found there, I never met with.) 



E. LUTEUM, Pursh. ? (G.) Without flowers. (Steilacoom, S.) 



(ENOTHERA BIENNIS, Linn. (T.) Very common on every prairie throughout the country. A 

 very large flowered variety grows in meadows at the mouth of the Columbia, with low, spread 

 ing, slender branches, not more than a foot in length, in habit resembling (E. fruticosa. 



(E. VINOSA, Lindl. (G.) O. Romanzovii? On the prairies near Vancouver and Steilacoom 

 I collected two quite distinct purple species, growing in the same soil, and apparently holding
