long, sparingly appressed pubescent, not thickened below the apex. 

 Fruits unknown. Fruit sparingly produced, subglobose, 5-6 ram. thick 

 blue or rather light blue, appressed-setulose; stone slightly higher than 

 broad, 4 mm. long and 3.75 mm. wide, slightly compressed and slightly 

 oblique, faintly ribbed. 



Cultivated at Highland Park, Rochester, New York and in the Arnold 

 Arboretum; specimens seen: Highland Park, August 29, 1919, and July 

 9 and September 6 or 16, 1920, Wm. L. G. Edson (No. 0-1108, type), 

 July 12, 1920 (No. 0-1105); August 29, 1919 (No. 0-1106); Aug. 29, 1919 

 and July 17, 1920 (No. 0-1109), and July 17, 1920 (No. 0-1110), Wm. G. 

 L. Edson; Arnold Arboretum, September 13, 1921, A. Rehder (plants 

 received from Rochester in 1916). 



This hybrid originated in Highland Park at Rochester from seed of 

 Cornus macrophylla Wall. (C. brachypoda C. A. Mey.), but differs from 

 that species in the slenderer paler colored branchlets, in the narrower 

 somewhat smaller leaves, rough above by short scabrid hairs, and be- 

 neath covered with more numerous longer less closely appressed and 

 partly curved hairs, in the fewer more or less pubescent veins, (usually 

 7-8 in C. macrophylla and glabrous beneath), it further differs in the 

 denser and smaller, more pubescent umbel-like corymb, in the pubescent 

 style and in the blue fruit. In these characters the hybrid approaches 

 C. asperifolia Michx. which is probably the other parent, but it differs 

 from that species in the larger leaves, only slightly rough above, and 

 beneath with nearly appressed pubescence, in the more numerous slightly 

 appressed pubescent veins (in C. asperifolia 4-5 and furnished with 

 spreading villose hairs), in the sparingly appressed pubescent inflores- 



, in the longer sepals and longer petals and in the blue fruit. 



Though this hybrid is not as handsome as C. macrophylla it has the 

 advantage of being hardier and therefore may be recommended for re- 

 gions where C. macrophylla will not stand the winter. 



X Cornus Horseyi (C. amomum x macrophylla) , hybr. no v. 



Large shrub, with spreading branches, young branchlets slightly quad- 

 rangular with sparse short appressed hairs, becoming dark purple at the 

 end of the season. Leaves elliptic-ovate to oblong ovate, 5-10 or on 

 shoots to 12 cm. long, 2-5.5 cm. broad, long-acuminate, broadly cuneate 

 or nearly rounded at base, dark yellowish green above and appressed- 

 pubescent at first, soon glabrous, grayish green or pale green beneath 

 sparingly furnished with straight appressed hairs, occasionally inter- 

 mixed particularly toward the base of the leaf with fulvous hairs, with 

 5-7 pairs of veins, prominent beneath and slightly appressed-pubescent or 

 nearly glabrous, the midrib beneath furnished with scattered appressed 

 minute fulvous hairs, intermixed with pale hairs; petiole 0.5-2 cm. long, 

 with minute appressed fulvous and pale hairs. Flowers in rather dense, 

 convex or rather flat corymbs 5.5-6.5 cm. across; peduncle 3-4 cm. long
