BOTANY OF THE ROUTE. 63 



wings of the fruit equal, (broad and white.) On the sands of the sea-shore at Shoalwater 

 bay, scarcely rising above the surface, where its leaves lay prostrate. These are dark green 

 and glabrous, and nearly white below, drying up, but not deciduous ; flowers gray and white ; 

 ripe fruit, white." — Dr. Cooper. "Root thick, petioles stout, a span long. Leaflets and 

 divisions of the leaf 1 or 2 inches long ; peduncle 1 to 2 inches long ; rays 10 to 12, half an 

 inch to an inch in length ; umbellets capitate, many-flowered. The verj^ little fruit gathered 

 is imperfect, but accords with that of Cymopterus, (except that the vittee were not made out,) 

 but the foliage is widely different from that of any species before known." — Gray. 



Pedcedanum leiocarptjm, Nutt. (G.) Prairies generally ; on sandy sea-shore varies with 

 leaves broader and shorter; stem coarse, 1 to 2 feet; June. "The green stems are peeled 

 and eaten." (G.) 



P. fceniculaceum, Nutt, (T.) Prairies about Puget Sound; March 15 to June — ; common; 

 flowering when two inches high to one foot. "Root boiled and eaten." (G.) 



Heracleum lanatum, Michx. (G.) Abundant on sandy prairies along coast; May. 



Daucus pusilltjs, Mich. (G.) Rare on sandy prairie near mouth of Columbia; July. 

 (Steilacoom, S.) 



Glycosma occidentalis, Nutt. (T.) Common on rich prairies in shade ; June to August. 



CoNiUM MACOLATUM, Linn. "Large form of the northwest coast." (T.) Abundant every- 

 where in wet grounds, the large variety mostly near the sea, 8 feet high ; June to October. 



EcHiNOPANAX HORRiDUM, Smith, (G.) Common in springy woods, from the highest parts of 

 the Cascade mountains to the coast; May 15. (Steilacoom, S.) 



CoRNUS Drummondii, (G. a. Meyer,) C. sericea, var.? Torr. & Gray. Abounds along the 

 edge of rivers, in sandy soils, down to tide-water. I think this is distinct from the following, 

 though my specimens are too incomplete to decide from. 



C. PUBESCENS, Nutt. (T.) Not very common, in damp woods, Steilacoom ; May 28 ; 15-20 

 feet high. Bark greenish, twigs dark purple, leaves from two to four inches long, one to two 

 and a half wide, ovate, obtuse or mucronate, glabrous, petals white. 



C. NuTTALLii, Aud. (G.) Common in the fir forests, about as far north as Steilacoom ; May 

 1. Very similar to C. Florida, and about twice as large in all parts. Much more ornamental 

 in flower. 



C. Canadensis, Linn. Cascade mountains, 4, 000 feet to the mouth of Columbia ; May. 



LiNNEA borealis, Gronovius, (G.) Common in the same situations as Cornus Canadensis; 

 June. (Steilacoom, S.) 



Symphoricarpus racemosus, Mich. (G.) Common along river banks down to tide-water ; 

 June. (Steilacoom, S.) 



S. OCCIDENTALIS, R. Br. (T.) With the preceding, but less common; June to August. 



LoNiCERA OCCIDENTALIS, Hook. Not Uncommon about Puget Sound or borders of prairies. 

 Resembles L. sempervirens in habit and growth, but the flowers are much less beautiful and 

 smaller ; orange ; May 1 to June. Limbs of the corolla slightly unequal. 



L. HISPIDULA, Dougl. Not very common ; woods near mountains ; May-June. Flowers rose. 



L. (Xylosteum) involucrata, (Rich.) Wet ground, Cascade mountains to coast, especially 

 about brackish marshes ; April to July. Corolla bright yellow, bracts purple, becoming much 

 larger and brighter as the fruit ripens. Berries united, dark rich purple. A variety collected 

 in flower, April 22, on Whidby's island, has all parts much smaller, the leaves ovate-lanceolate, 

 flowers paler, and bracts green. The larger form seems rare near Puget Sound.
