Aralia continued. 



approaching maturity, the leaves are trifoliate, the leaflets being 

 rounded and toothed, and the terminal one being about double 

 the size of the lateral ones. Stems erect, brownish-green, spotted 

 when young with pale elongate blotches. Polynesia, 1882. 



A. Schefflerl (Scheffler's). L on long petioles, digitate ; leaflets 

 five, petiolulate, lanceolate, attenuated at the base, serrulated, 

 glabrous on both surfaces. Stem shrubby, smooth. New Zealand. 

 Greenhouse species. 



A. spectabills (showy). A synonym of A. concinna. 



A. spinosa (thorny).* Angelica Tree. I. doubly and triply pinnate ; 

 leaflets ovate, acuminated, deeply serrated. Stem simple, prickly 

 (as are also the petioles), forming into an umbrella-like head, 

 deciduous, h. 8ft. to 12ft. North America, 1688. A very fine 

 hardy species for sheltered spots. 



A. spinnloaa (small-spined). L alternate, pinnate; pinna; ovate 



Aralia continued. 



A. V. gracillima (most graceful).* I. alternate, spreading ; leaflets 

 nearly linear, but slightly narrowed at both ends, havmj a pro- 

 minent ivory-white central rib. South Sea Islands, 1878. An 

 erect growing species, with an elegantly graceful habit. It is 

 allied to A. reticulata, but is more handsome. This charming 

 variety is undoubtedly the finest for table decoration, and is 

 frequently grafted upon stocks of the typical form. It enjoys 

 plenty of heat. SYN. A. gracillima. 



ARALIACEJE. An order of trees, shrubs, or (rarely) 

 herbaceous plants, often pubescent, and sometimes spiny. 

 Flowers variously disposed, hermaphrodite or unisexual, 

 regular ; petals usually five, and valvate. Leaves alternate, 

 or (rarely) opposite. This order is closely allied to Umbel' 

 lifera ; and the best known genera are Aralia and Hedera.

A.ternata(three-leafleted). L opposite, ternate; leaflets oblong- 

 lanceolate ; margins in some cases deeply serrate, in others sinuate, 

 light green. New Britain, 1879. A slender growing species.

 undulated leaflets, glossy green above, dark red beneath ; petioles 

 long and slender. New Caledonia, 1867. A very handsome (said 

 to be the best) species, with slender, erect growing stem. See 

 Fig. 143, for which we are indebted to Messrs. Veitch and Sons.

ARAT7CARIA (from Araucanos, its name in Chili). 

 STN. Eutacta. OBD. Conifera. A noble genus of 

 dioecious or sub-dioecious evergreen trees, with usually 

 imbricated persistent flat sessile scale-like leaves. Male 

 cones large, cylindrical, terminal ; female ones very large, 

 globular, terminal, with dense ligneous deciduous scales, 

 each bearing a solitary seed. The majority of the species 

 aro not, unfortunately, sufficiently hardy to withstand our
