1. Aralia Thomsoni, Seem. Rev. Hed. 91. A large prickly shrub, 

 all parts more or less softly pubescent or tomentose. Stem slender, 

 the prickles remote. Leaves large, 2-3-pinnate ; leaflets thickly membra- 

 nous, 5-9 in each ultimate pinnule, ovate-lanceolate, acuminate, the 

 base rounded and somewhat oblique ; the petiolules of all except the 

 terminal very short (usually less than '1 in. long), that of the terminal 

 leaflet "5 in. or upwards, the edges entire or minutely serrulate ; upper 

 surface sparsely strigose, the nerves and midrib pubescent ; the lower 

 softly tomentose ; length 2*5-3'5 in., breadth 1-1*75 in. Panicles 15-20 

 in. long, with short sub-horizontal branches ; the ultimate branches 

 umbellate ; the bracts narrowly lanceolate, "25 in long. Fruit '15 in. 

 long, somewhat wrinkled, glabrous, the ridges broad. Clarke in Hook,

 slightly oblique or sub-cordate ; sessile except the terminal one ; petiolule 

 of the terminal leaflet under 1 inch ; length of leaflets 3-5 in., breadth 

 15-2 in. ; upper surface with a few sparse adpressed hairs, otherwise 

 glabrous ; lower with scattered white flexuose hairs especially on the 

 nerves and midrib. Panicle 15-18 in. long, pubescent in its ultimate 

 3-fid branches, the lower part glabrous, ultimate branchlets umbellate ; 

 the pedicels slender •3-4 in. long, tomentose. Fruit nea^rly '2 in. long,
