Crataegus cordata, coccinea, pyrifolia, elliptica, glandulosa, 

 parvifolia, flava, punctata, Crusgalli, Oxyacantha (including 

 monogyna), and Azarolus Jfilld.; crenulata, Roxb.; Mespilus 

 Pyracantha, W. ; tanacetifolia, Smith ; Pyrus terminalis, W. 

 And probably 



Crataegus viridis, maura, pentagyna, Willd. ; nigra, TV. et K. ; 

 apiifolia, spathulata, Mich.; turbinata, Pursh; melanocarpa, 

 orientalis, Bieberstein. 



CratcBgus thus limited is a strictly natural genus divisible into 

 two sections, of which the first may contain the species with 

 evergreen nearly entire leaves, and the other those with angular 

 deciduous ones. Each will be increased with several unpublished 

 plants in the Banksian herbarium ; and among the drawings of 

 the Chinese is a species with quinate leaves. 



Mespilus Pyracantha L. is referable to the first section, not- 

 withstanding it differs in some respects.
