from the fruit of C . casta. Its flowers have 20 stamens with 

 pale pink anthers, and its branches are furnished with numerous 

 short branchlets and rather small slender spines. 



Crataegus hystricina Ashe 

 The hedgehog thorn is probably so named because of its numerous 

 spines. It has been found in our territory at Thompson Lake only. 



Crataegus illuminata Sarg. 

 The illuminated thorn, in habit and general appearance of its 

 foliage, is similar to C . d o d g e i . Its fruit is usually a little longer 

 than broad and ripens earlier than the fruit ofC. dodgei. 



Crataegus mellita Sarg. 

 The honey thorn is very closely related to the Brainerd thorn, 

 C. brainerdi, to which I formerly referred it, but from which 

 it may be separated by its thinner leaves. Its fragrant honey-pro- 

 ducing flowers are suggestive of the specific name. It is yet limited 

 to a single locality. It inhabits rocky soil. It is remarkable in 

 retaining the freshness of its reddish filaments almost to the time of 

 ripening of its fruit. 



Crataegus menandiana Sarg. 

 The Menand thorn is a large shrub belonging to the group Tom- 

 entosae. Its flowers have 20 stamens, but it differs from all our oth- 

 er species with 20 stamens in having red anthers. They are more 

 highly colored than in our specimens of C. gemmosa and 

 C. succulenta. 



Crataegus oblongifolia Sarg. 

 The oblong leaved thorn belongs to the group MoUes and is re- 

 lated to C. exclusa. Its flowers have the anthers more highly 

 colored than in the Albany form ofC. exclusa, and some of 

 the leaves are much longer than broad, a character suggestive of the 

 specific name. It is at present limited to the Menands locality so 

 far as is known. 



Crataegus peckietta Sarg. 

 The second Peck thorn is a northern species. It has been found 

 at Piseco and Lake Pleasant in Hamilton county, at Keene and 

 Port Henry in Essex county and at Horicon in Warren county. 

 It sometimes retains a part of its fruit through the winter. The 

 fruit is so peculiar in shape that often it is recognizable even after 

 the shriveling and discoloration it undergoes during the winter.
