* This name was proposed by Mr. Ashe to replace Crataegus densiflora Sargent for the 

 reason, as he states, that the latter had been previously used in the genus (Desf . ex K. Koch, 

 Dendr. 1. 186, as a synonym). However, Desfontaines does not appear to have made such a 

 combination, the error apparently having been made by Koch in transcribing from Spach 

 (Hist. Veg. ii. 88). Since the name Crataegus densiflora Desf. is thus not a valid name and 

 has no standing, Sargent's specific name must be maintained.
