a woolly substance, and hence the botanic name 

 Eriobotrya, which signifies woolly grapes. 

 The tree will stand out in the open air in 

 England, and it will flower freely in a green- 

 house, but it requires a stove to ripen its fruit. 

 Cotoneaster and Amelanchier were also for- 

 merly included in Mespilus, and they are very 

 closely allied to Photinia and Eriobotrya. The 

 species belonging to Photinia, however, are 

 easily known by their shining leaves, and the 

 petals of their flowers being reflexed, that is, 

 curved back ; and the species of Eriobotrya are 

 distinguished by their woolliness, which spreads 

 over even the flowers and fruit. The Coto- 

 neasters are known by the small petals of their 

 flowers, which curve inwards, and remain a long 

 time without falling. The leaves are also thick, 

 and w^oolly or clothed with rusty hair on the 

 under side ; and the flowers, which are pro- 

 duced in cymes or panicles, with woolly pedi- 

 cels, are followed by bright red havrs, resem- 

 bling those of the hawthorn. Lastly, the genus 

 Amelanchier is known by its long narrow petals, 

 and its ovary having five or ten cells, with five 

 styles united at the base.
