Hab. Common on the plains of the Multnomak and Umptqna rivers ; also near the sea at Cape Orford, 

 North-West America. — If this plant be rightly referred to the S, TnalvcBflora of De Cand., it is a native also 

 of Mexico, and perhaps of all the intermediate country near the coast. 



2. jS. coccinea; stellato-pubescens incana, caulibus erectis, foliis longe petiolatis pro- 

 funda tripartitis fere ternatis, segmentis lateralibus bipartitis, intermedio trifido, racemis 

 terminalibus foliosis. — De Cand, Prodr. v, 1. jp. 465. — Malva coccinea. " Frasefs Cat J*

Hab, On the plains of the Saskatchawan. Drummond. — There certainly is no involucre to the calyx of 

 this plant, only a solitary linear-subulate hractea ; hence, with De Candolle, I refer it to Sida : but, it must be 

 confessed, in habit and in the rich scarlet hue of its flowers, it much resembles Malva Munroana, with which 

 Mr. Douglas compares it. The germen is globose, densely covered with a white, compact, cobwebby sub- 

 stance. Capsules 1-seeded, about 6, very compactly and circularly arranged, as in Malva, forming a somewhat 

 transversely-oblong fruit, depressed in the centre. The capsules are easily separated in maturity, and are 

 indehiscent.

Hab. Throughout Canada. {Lady DaUiousie ; Mrs, Sh^^ard; Mrs. Percival ;) and in the interior, as 

 far as Norway House; Dr. Richardson ; Drummond; JOouglas.—The bark of this tree, which is called Bass- 

 wood, is employed for a variety of economical purposes where a coarse kind of cordage is required ; and 

 the wood is used by cabinet and carriage-makers. Mr. Douglas speaks of this as one of the most ornamental 

 and useful trees in Canada.
