1 00 Mr. J . Li ,nd l e y s Observations 



Petala orbiculata, patentia (margine crispa). Loculi cultarum 

 sapissime vacui. 

 1. Mespilus germanica Willcl. 2. M. grandiflora Smith Exot. 

 Bot. 



To plants with these characters I propose to limit Mespilus. 

 which will then include those species only with eatable fruit. It 

 will be distinguishable from all the other genera with osseous 

 endocarp by the foliaceous segments of its calyx, and fruit whose 

 cells are naked at the top, and not covered over by the incras- 

 sated disk and connivent segments, as in Crataegus, Sec. 



The remainder of the genus in Willdenow is a mass of species 

 differing as much from each other as from true Mespili. Thus, 

 M.japonica constitutes my genus Eriobotrya ; M. Pyracantha is 

 not distinct from Cratcegus ; M. Chaincemespilus is a Pyrus ; and 

 Cotoneaster and tomentosa belong to Medicus's genus Cotone- 

 aster.
