2. L. decurrens, Torrey. Syn. Thuja Craigiana, Jef- 

 frey ; T. gigantea, Gordon ; T. Lobbii, Hort. Leaves 

 very small, adpressed, awl-shaped or scale-formed, sharply 

 acute, decurrent, not acerose, bright glossy-green color. 

 Branches, spreading, incurved at the extremities, with nu- 

 merous, compressed branchlets. Cones, ovate-oblong, 

 pendulous (Bigelow) ; scales enlarged below the apex, 

 with recurved, tubercle-like spines, the upper ones much 

 the largest. Seeds, two-winged, unequal in size. 



This is not a synonym 

 of Thuja gigantea, as

 pean authors claim ; but 

 a very distinct tree be-

 genus. Douglas was 

 greatly in error when he 

 made the assertion that 

 it was found near Nootka 

 Sound. Seeds of Thuja 

 Craigiana, collected by 

 Jeffrey, and grown near 

 Philadelphia, have pro- 

 duced young plants iden- 

 tical with the L. decur- 

 rens. Dr. Torrey, in the 

 Smithsonian Contribu- 

 tionsf states that it in- 

 habits the upper waters
