Hab. N. W. America. Sitcha. Bongard. Columbia. Dr Scouler, N. E. of Fort Vancouver, in over- 

 flowed woods. Dr Gairdner.^My specimens from Dr Scouler and Dr Gairdner are considerably injured : 

 but they are sufficiently perfect to satisfy me that the plant is a Spnplocarpus, and the S. Kamtschaticus of 

 Bongard. The root is perennial, bearing large coarse fibres. Leaves, which are clothed at their base with large 

 membranous sheaths, a foot to a foot and a half long, thin, membranaceous, ovate, but tapering gradually 

 into a broad and short foot-stalk: the midrib very broad, especially at the base of the leaf. Spatha, includ- 

 ing the long tube, nearly equal in length with the leaves : the tubular part sheathing the long peduncle of 

 the spadix.
