some of the leaves of vigorous young shoots are more or less wrinkled. 

 The stamens are 7-10, the anthers rose-red and the styles 3-4. 



Crataegus glaucophylla Sarg. 

 Seneca park and Genesee Valley park, Rochester. Westport, 

 Essex CO. In the typical form of this species the leaves at flower- 

 ing time have a glaucous bloom on the upper surface and are pale 

 and glaucous beneath. This glaucous bloom is sometimes wanting. 

 The stamens vary from 5-10 and the anthers are rosy red. On 

 vigorous shoots the leaves are sometimes slightly cordate. The 

 fruit is longer than broad, bright red or scarlet and sometimes 

 hangs on the branches long after the leaves have fallen. 



Crataegus ornata Sarg. 

 Genesee Valley park, Rochester. Found also at La Salle, 

 Niagara co., by J. Dunbar. On fertile branches the leaves are 

 often oblong ovate but on vigorous young shoots they are broadly 

 ovate. The stamens are 10, the anthers rose-red and the styles 

 2-3. The fruit hangs in drooping clusters, is of a bright scarlet 

 color and quite ornamental. 



Crataegus rubicunda Sarg. 



Genesee Valley park, Rochester. It has been found at Buffalo 



by J. Dunbar. It closely resembles the preceding species, from 



which it differs in the slight hairiness of the calyx and pedicels, in 



the red flesh of the fruit and in the yellowish green color of the 



foliage. 



Crataegus tenuiloba Sarg. 



River bank south of Rochester. The thin lobed thorn has ovate 

 or broadly ovate leaves and is similar in its general characters to the 

 two preceding species but it differs from them in having smaller, 

 fewer flowered clusters and in its bright scarlet fruit which is gradu- 

 ally narrowed toward the base. 



Crataegus colorata Sarg 

 Genesee Valley park, Rochester. It has also been found at Mur- 

 ray, Orleans co. by M. S. Baxter and at Buffalo by J. Dunbar. It 

 differs from the five preceding species in having its ripe fruit crim- 

 son instead of scarlet. Its stamens are 10, anthers rose-red and 

 styles 3-4. Its branches bear numerous spines which are slender or 

 stout, straight or curved.
