22 SILVA OF NORTH AMERICA. CORNACEA, 
loose spreading red-stemmed clusters, and ripens from the end of August until October ; it is subglobose, 
white, tipped with the remnants of the style, and about a quarter of an inch in diameter. The 
nutlets, which are covered with a thin coat of dry bitter flesh, are full and rounded, broader than high, 
somewhat oblique, and slightly grooved on the edge.! 
The wood of Cornus asperifolia is close-grained, hard, solid, and pale brown, with thick cream- 
colored sapwood. 
Cornus asperifolia is distributed from the northern shores of Lake Erie, where it is abundant 
on Point Pelee,” to Minnesota,’ eastern Nebraska‘ and Kansas,’ and through Missouri and the Indian 
Territory to eastern Texas, and to Mississippi, Alabama,’ South Carolina, and Florida. 
Cornus asperifolia, although it was discovered by the elder Michaux more than a century ago, is 
still rare in gardens. It was introduced into the Arnold Arboretum in 1884, and is perfectly hardy in 
eastern Massachusetts. 
1 The size and shape of the nutlet have been used to separate the 
trans-Mississippi plant as a variety of the eastern species (Coulter 
& Evans, Bot. Gazette, xv. 36). In Arkansas and Texas the nut 
is sometimes rather smaller and broader in proportion to its height 
than it is usually in the fruit of eastern plants, but the nuts vary so 
much in size and shape that it is hardly practicable to base varietal 
characters on them.
