" This section, which probably extends across the con- 

 tinent of Asia, from Nepal to China, is re^ily distin- 

 guished from the preceding by the thick wooliness of its 

 fruit; a peculiarity entirely confined to itself. Its leaves 

 are very dense, usually shining, and the prickles are placed 

 under the stipulse in pairs : the species which compose it 

 may be considered to have their organs of fructification in 

 the highest state of developement in the genus. The sta- 

 mens vary ftom 350 to 400, and the pistilla from 140 to 

 190; the former being twice and the latter three times as 

 numerous as in the last, section (Feroces), which perhaps 

 holds the next rank in tl^-scale of develop^nent.** 



" Branches pale brown, flexuose, covered with very soft 

 down; prickles generally naked, with a long base, bright 

 brown, pointing upwards, placed by pairs under the sti- 

 pulse, which are nearly distinct, dowriy, and divided at 

 the margin into several capillary compound segments, here 

 and there fringed with glands ; on vigorous rootshoots they 

 are united halfway, and then the part which is disengiu;ed 

 frequently extends into a small pinnate leaf ; petioles sloi- 

 der, downy, with a few small prickles ; leaflets 3-9, elliptic, 

 lanceolate, obtuse, bluntly serrate, dull green, naked above, 

 downy (rarely naked) and paler beneath. Flowers white, 

 subsolitary, surrounded by three or four approximate 

 leaves; bractece pectinate, woolly, as are the short pe- 

 duncle, globose htbe of the cafyx, and spreading entire
