1 78 Rosaces Amelanchier. 



varieties are very hairy when 3 7 oung, but eventually become 

 glabrous. A. spicatus, A. Botryapium, A. ovalis, &c., are 

 slight varieties. In fact, we have been unable to find con- 

 stant characters to separate European and American forms. 

 Those adduced by Koch break down when tried with a complete 

 series of specimens. 



ORDER XXXIX. SAXIFRAGES. 



(Including Escallonidcece, Hydrangeacece, CunoniacecB, Francoacece, 

 Grossulariacece, Philadelphece, &c.) 



Trees, shrubs, or herbs of variable habit. The structure of 

 the flowers in this order is very similar to that of the Rosacece, 

 and in some species so close as to render it a matter of doubt 

 to which order they should be referred. The tendencies in this 

 group are to few stamens, united carpels with numerous seeds, 

 and abundant albumen. 73 genera, including about 540 species, 

 are brought together under this order. They inhabit all 

 countries. 



TRIBE I. SAXIFRAGES. 



. Herbs, often scapigerous. Leaves usually alternate. Flowers 

 nearly always pentamerous. Fruit 1- to 3-celled. 



1. ASTlLBE (Hoteta). 



Tall branching herbs with triternate leaves and membra- 

 naceous stipules, having the aspect of some Spiraeas, and very 

 near them in structure ; but differing in the stamens not 

 exceeding 8 or 10, and the carpels 3, and the numerous 

 albuminous seeds. The few species known are from the 

 Himalayas, Java, Japan, and North-eastern America. The 

 name is derived from a privative and o-r/X/Sr/, brilliancy, in 

 allusion to the inconspicuous flowers of some of the species. 



1. A. barbata, syn. A. Japonica, Hoteia barbata, H. 

 Japonica, Spircea barbata and S. Japonica. The latter is 

 the name it usually bears in gardens, though it does not belong 

 to that genus. This is a very handsome plant, and now very 

 extensively cultivated. It grows about 18 inches or 2 feet 

 high, with triternate or pinnate leaves on long petioles. 

 Leaflets serrated, bearded with rufous bristly hairs, especially 

 on the joints of the petiolules, hence the specific name. The
