serrate or nearly entire ; bracts and stipules not prominent. Umbels 

 solitary or in racemes or panicles, rarely in compound umbels ; pedicels 

 usually jointed close under the flower. Flowers often polygamo-monce- 

 cious. Calyx with its margin truncate or 5-toothed. Petals 5, ovate, 

 imbricate in bud. Stamens 5. Ovary 2-5-celled ; styles 2-5, free or 

 shortly connate at base. Fruit 4-5-celled, 4-5-angular, or subglobose, 

 2-3-celled. Albumen uniform. Distrib. Species about 50 ; extending 

 from India and Malaya to Japan and North America. 



Leaflets entire or minutely serrulate, densely ferrugineous- 



tomentose on the lower surface ... ... ... 1. A. Thomsoni. 



Leaflets coarsely and somewhat unequally serrate, the lower 



surface with scattered flexuose white hairs ... ... 2. A. armata. 



Leaflets obscurely undulate-serrate, quite glabrous on both 



surfaces, the lower sub-glaucous ... ... ... 3. A. ferox. 



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 25-3"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.

2. Aralia armata, Seem. Rev. Hed. 91. A prickly shrub ; stem 

 slender, almost glabrous except the puberulous young parts. Leaves 

 very large, 3-pinnate, the rachises puberulous ; leaflets thinly mem- 

 branous, 9-11 in each ultimate pinnule, ovate-lanceolate, acuminate, 

 the edges coarsely and somewhat nnequally serrate ; the base rounded, 

 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 

 1*5-2 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 nearly *2 in. long, 

 glabrous; the ridges broad, flat. Kurz For. Flora Burma, I, 536;
