“This section, which probably extends across the con- 
tinent of Asia, from Nepal to China, is readily 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 stipule 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 from 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 the scale of developement.” 
© 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- 
pula, which are nearly distinct, downy, and divided at 
the margin into several capillary compound segments, here 
and there fringed with glands ; on vigorous rootshoots they 
are united half way, and then the part which is disengaged 
frequently extends into a small pinnate leaf; petioles slen- 
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; bractee pectinate, woolly, as are the short pe- 
duncle, globose tube of the calyx, and spreading entire ©
