of about 7 or 9 leaflets, these obovate, obtuse, closely serrate, 

 green and nearly or quite glabrous above, glaucescent and 

 soft-pubescent beneath ; stipules broad and short, the petiolar 

 vein beneath with a few firm spines, their margins more or 

 less glandular-ciliate : flowers solitary, the short petiole 

 sparsely armed with gland-tipped spines ; calyx-tube with not 

 a few stout sharp spreading spines, but sepals quite densely 

 glandular-prickly ; corolla large, the petals obcordate. 



Species known only in good flowering branches collected at 

 Moose Jaw, Assiniboia, by Mr. William Spreadborough, in 

 June, 1892, and communicated to me by Mr. J. M. Macoun. 

 The Canad. Survey number is 10,624. 



The type of my R. Macounii (Pitt. iv. 10) is also from 

 Assiniboia, but is very different from this. 



Some Allies of Hibiscus Moscheutos. 



Taking Gray's Synoptical Flora for the authority upon our 

 hydrophile kinds of Hibiscus, a northern botanist would believe 

 without a doubt that the broad-leaved pink-flowered plant of 

 New England marshes is to be H. Moscheutos, Linn. Never- 

 theless Linnaeus, who rarely distinguished species where they 

 were not well marked, said that this northern plant should be 

 called H. palustris. Its leaves are not only broad, but are 

 lobed, and this with some suggestion of the outline of maple 

 leaves. They say that the flowers of this, commonly of a 

 pinkish or light rose-color, are sometimes white. But let the 

 New England plant lover, taught that his northern plant is 

 H. Moscheutos, come southward in summer time to the marshes 

 of Chesapeake Bay and its tributaries, and he will be apt to 

 ask what this hibiscus is that has always large cream -colored 

 corollas, and with long narrow lanceolate and wholly uncut 

 foliage ; for he will not believe, unless his faith in great books 

 is immovable, that this and the other are the same. 



The northern plant is H. palustris. Only the great yellowish-
