IDENTIFICATION OF CHERRY VARIETIES 15 



6. OSTHEIM 



This variety is easily distinguished from others of the Morello type by its 

 rather short slender growth, yellowish brown bark, slender pointed buds, small 

 elliptic leaves, with very dull, fine texture, light yellowish green color, and fine 

 single serrations. Its glands are also distinctive, being very small, round, and 

 usually on the base of the blade. 



7. Olivet — Early Richmond 



Olivet more closely resembles Early Richmond than any other common vari- 

 ety. It is a somewhat stronger grower, slightly more upright, with a little darker 

 bark and fewer, larger, and more raised lenticels than Early Richmond. Olivet 

 leaves are larger, more pointed, with a tendency toward twisted tips, less folding, 

 more spreading position, duller surface, and sharper serrations. 



8. May Duke, Reine Hortense, and Abbesse d'Oignies 



These three varieties are distinctly sweet-type Dukes. All have upright - 

 spreading trees with rather long slender branches, fairly large pointed buds, and 

 rather large leaves with fa>rly coarse serrations. As distinguished from the two 

 others, the young tip leaves of May Duke are reddish; there is less pubescence 

 on its petioles; its leaf glands are smaller, fewer, and redder; and its leaf color 

 shows less yellow in the green. May Duke shows less of the crooked branch 

 character than does Reine Hortense; also its leaves are somewhat smaller and 

 less folded and have shorter petioles and somewhat more glossy surfpce than that 

 variety. May Duke bark is darker brown than that of Abbesse. 



9. Reine Hortense — Abbesse d'Oignies 



Reine Hortense has darker colored bark, more crooked branches, more pointed 

 buds, and fewer lenticels than Abbesse. Its leaves are darker green, with more 

 acuminate apex, and coarser, more prominent serrations than those of Abbesse. 

 Reine Hortense petioles are longer, with less pubescence and the glands are more 

 apt to be stalked. 



10. Royal Duke — Brassington 



In many respects these two varieties are similar. However, Royal Duke is 

 taller and has somewhat more lenticels. Its leaves are somewhat larger and longer, 

 with narrower leaf base, somewhat longer apex, and coarser serrations than Brass- 

 ington. Royal Duke petioles are longer. The leaves on the upper half of Royal 

 Duke shoots are more folded and more erect in position. Royal Duke is also 

 more leafy in the head of the tree than is Brassington. 



11. Late Duke 



Two-year trees of this variety are similar to Reine Hortense in habit of growth 

 and like that variety have crooked shoots, but their bark color is darker brown. 

 Also they have somewhat more lenticels, which are both large and small with the 

 bark split above and below each. One-year trees of Late Duke most nearly 

 resemble those of Royal Duke. However, the side shoots on Late Duke curve 

 upward while those of Royal Duke are straight. Furthermore, Late Duke leaves 

 have somewhat longer tips, somewhat smoother surface, somewhat finer serra- 

 tions, and rather small reniform. greenish glands, often on the base of the blade, 

 while those on Royal Duke are larger, rounder, yellow, and usually on the petiole. 

 Late Duke loses most of its lower leaves with leaf spot, while those of Royal 

 Duke are little affected by that disease. The color of the young tip leaves is 

 darker on Late Duke than on any other variety in this group except May Duke.
