Horticultural Society, have upright slender 



branches ; glabrous green leaves, somewhat 

 like those of the elder; and small black fruit, 

 like those of P. «rbutifolia. It is a very dis- 

 tinct kind, and well deserves a place in col- 

 lections. It is probably the same as P. 

 sambucifolia of Cham, in Linn., ii. p. 36., and 

 of Don's Mill., ii. p. 648., which is stated 

 to be a native of Kamtschatka. There are 

 fine specimens of this tree in the Horticul- 

 tural Society's Garden, and one at Syon 

 which is 12 ft. high. In the Bot. Reg., t. 1 196., 

 it is stated that the figure of this species in 

 Watson is by no means that of P. sorbifolia, 

 but is that of P. pinnatifida ; but this appears 

 to us a mistake, since P. pinnatifida has red 

 fruit, and the figure in Dendrologia has black fruit, with the leaves answering 

 to the specific "description given above, and to the plants under this name 

 in the Horticultural Society's Garden, and at Messrs. Loddiges. 



Variety. 



¥ P. s. 2 pendula Hort., Sorbus hybrida pendula Lodd. Cat., P. spuria 

 sambucifolia Hort. Brit., and the plate of this sort in our Second 

 Volume, has pendulous shoots, and is a very distinct and most inte- 

 resting kind. There are fine low trees of it in the Horticultural So- 

 ciety's Garden ; and, if grafted 10 ft. or 12 ft. high, instead of only 

 3 ft. or 4 ft., as it is there, it would form one of the most beautiful 

 of pendulous trees. It is prolific in flowers, and dark purple fruit ; 

 and the leaves die off of an intensely dark purplish red. 



App. i. Additional Species of Yyrus belonging to the Section 



Sorbus. 



F.foliolbsa Wall. Cat., p. 677. ; PI. Asiat. Ear., 2. p. 81., 1. 189. ; is a tree growing to the height of 

 20 ft., with pinnate leaves, and elliptic-lanceolate, mucronate, leaflets, pubescent beneath ; with white 

 flowers, succeeded by small roundish red fruit. 



P. hircina Wall. Cat., p. 675., and Don's Mill., 2. p. 648., is a native of Nepal, with pinnate leaves, 

 and numerous leaflets, rusty beneath ; with red fruit, about the size of those of the common mountain 

 ash. 



Other Sorts. There are some other names in the nursery catalogues, which are probably synonymes 

 to some of the preceding sorts ; but, at all events, we can make no use of them here ; the species and 

 varieties of this section being, as we have already observed, in a state of great confusion. 



§ vii. Adenorachis Dec. 



Sect. Char. Petals spreading, each with a claw, and a concave limb. Styles 

 2 — 5. Pome globose. Leaves simple, the midrib bearing glands on its 

 upper surface (which is the character expressed in the sectional name). 

 Flowers in branched corymbs. Deciduous shrubs, natives of North 

 America; growing to the height of 4ft. or 5ft., and prolific in flowers, 

 followed by red, dark purple, or black, fruit. They are all readily 

 propagated by division, by suckers, or by grafting on the common hawthorn. 

 This section is so unlike the others in habit and general appearance, that 

 it would be much more convenient to have it as a distinct genus ; say 

 Aronia, as it was before the change referred to in p. 879.
