 ralty Head, 0. Piper, May, 1898; Whidby Island, Gardner 194; Seattle, Piper 137; Tacoma, 

 Flett 219.

3. Ledum, columbianum sp. nov. 



Erect with erect branches, 60 to 90cm. high; bark becoming smooth and brown; leaves' 

 oblong, reticulate, 4 to 6 cm. long, rather obtuse but apiculate, strongly re volute, dark green 

 and glabrous above, whitish and resinous-dotted beneath, the midrib and short petiole 

 minutely puberulent as well; corymbs terminal, convex, 3 to 5 cm. broad; pedicels slender, 

 puberulent and resinous-dotted, recurved in fruit, 1.5 to 3 cm. long; lobes of the calyx very 

 small, broadly rounded; petals white, oval, 5 to 6 mm. long, obtuse; stamens 5 to 7, the 

 filaments sparsely hirsute at base; ovary minutely canescent and resinous-dotted; capsules 

 oblong, acutish. 



Collected by the writer in a sphagnum bog at Ilwaco, Pacific County, June 22, 1904 (no. 

 6451). The type is deposited in the U. S. National Herbarium. Also collected at Clatsop, 

 Oreg., by Coville, September, 1, 1898 (no. 869). 



This species is nearest related to L. groenlandicum, from which it may at once be distin- 

 guished by the absence of the tomentose pubescence. In this respect it resembles L.glan- 

 dvlosum alone, but the capsule characters are those of the former species. Its zonal 

 position is apparently Humid Transition.
