216 CORNACEAE 



site leaves are broadly to narrowly ovate and have mostly 4 

 or 5 pairs of veins. They measure at most about 5 inches 

 long by 2i/2 inches wide. They are usually abruptly narrowed 

 to a short or longish point at the apex and rounded or nar- 

 rowed, rarely subcordate, at the base, and large leaves often 

 are conspicuously asymmetrical at the base. The surface is 

 pubescent above and distinctly rough to the touch. Beneath, 

 it is woolly and mealy, and the hairs beneath are usually color- 

 less but may be reddish on the veins. The petioles are short, 

 commonly about ]/^ inch long. 



The inflorescence, a convex cyme, is likewise covered with 

 pubescence which frequently contains reddish hairs. The flow- 

 ers, which are open from late May through most of June, 

 mature fruit on bright red pedicels in August and September. 

 The fruit is white, nearly globose, and pulpy, and contains 

 stones that are conspicuously flattened laterally, but broader 

 than high, and smooth on the surface. 



Distribution. — The Roughleaf Dogwood prefers moist soil 

 along streams and rivers and ranges from Ontario to South 

 Dakota and south to Florida and Texas. In Illinois, it may 

 be found throughout the state, along streams and rivers bor- 

 dered by woods or shrub thickets. A hybrid between this species 

 and C. Amomum is in cultivation as an ornamental and is known 

 as X C. Horseyi Rehder. 



CORNUS BAILEYI Coulter & Evans 



This dogwood, fig. 56, is an erect shrub 3 to 6 feet high with 

 purplish or bright red, smooth branches and green or reddish 

 branchlets, which are at first pubescent but eventually become 

 smooth and purplish. The ovate leaves are 1 14 to 4 inches 

 long by ^ to 2i/^ inches wide, short or long pointed at the 

 apex because of the narrowing of the leaf blade, and rounded 

 or narrowed to the petiole below. There are as a rule 4 to 6 

 pairs of veins per leaf. The upper surface is more or less 

 pubescent with appressed hairs, and the lower surface is woolly 

 and densely white-mealy. The veins are frequently reddish on 

 the underside of the leaf. 



The inflorescence, a pubescent and generally also woolly 

 cyme 1 to 2 inches wide, blooms from about the middle of 

 May through the first week in June, and rarely also late in
