Pyrus communis, pollveria, nivalis, Malus, dioica, speetabilis, 

 prunifolia, baccata, coronaria, angustifolia, salicifolia, Aria, 

 intermedia, -WiWt > elaeagrifolia, Pall. ; amygdaliformis, Jill;

3. Folia simplicia. Petala parva, erecta, concava,

To the first section must be added several nndescribed species 

 from India and China in the herbaria of Sir Joseph Banks and 

 Mr. Lambert, with one from Mexico in the collection of the last 

 gentleman. Malus of Tournefort and Jussieu has styles united 

 towards their base. But this is scarcely of even specific import- 

 ance ; for it occurs in Cratagus Oxyacantha, which has com- 

 monly separate styles, and is variable in Chcenomeles and Ame- 

 lanchier Botryapium. 



Pyrus arbutifolia, and perhaps those allied to it, has the rudi- 

 ment of a spurious dissepiment.

 dium barbati. Ovula solitaria. Pomtim clausum, (ianatum,)
