Mr Dunbar. The late ripening globose fruit and the bronze red 

 autumnal foliage are noticeable characters of this species. It has 

 lo stamens with purple anthers as in C. diffusa, but in its 

 almost deltoid or triangular leaves and its nearly entire calyx lobes 

 it is quite distinct from it. 



Crataegus baxteri Sarg. 

 Seneca park, Rochester. It has also been found at Honeoye 

 lake by Mr Baxter and at Chapinville, Ontario co. by Professor 

 Sargent. It and the next following species belong to the section 

 Intricatae. 



Crataegus verecunda Sarg. 



Seneca park, Rochester. This is at present the only known 

 locality of this very rare thorn. It is a smaller shrub than the 

 Baxter thorn and its smaller fruit is longer than broad. The fruit 

 of C. baxteri is nearly or quite globose and ripens later. 



Crataegus fulleriana Sarg. 

 In the northern part of Rochester on the east bank of Genesee 

 river. It has been found at Rush and Rochester Junction, Mon- 

 roe CO., by Messrs Baxter and Dunbar. This and the two follow- 

 ing species belong to the section M611es. The Fuller thorn is a fine 

 and an attractive species. Its flowers have 20 stamens and its large 

 scarlet hairy but shining fruit is longer than broad. It may be 

 either rounded or pointed at the base and is crowned by the long, 

 very narrow and persistent calyx lobes which constitute a peculiar 

 feature of the species. 



Crataegus ellwangeriana Sarg. 

 Rochester and near Portage, Livingston co. The Ellwanger 

 thorn becomes a tree of considerable size. It differs from the 

 Fuller thorn in having only 8-10 stamens in its flowers, in its 

 shorter, stouter spines, shorter pedicels and broader calyx lobes. 



Crataegus spissiflora Sarg. 

 Genesee Valley park, Rochester. Between North Albany and 

 Menands, east of Troy road. The peculiar character of this species 

 and one suggestive of the specific name is its small compact clus- 

 ters of flowers. Much of the hairiness of its inflorescence and 

 early foliage disappears with age. Its fruit is generally a little 

 longer than broad. It is glabrous when ripe and of a bright scar- 

 let color, beautiful to behold.
