increased by cuttings of the half- 

 ripened shoots, or by layering the 

 ripened stems. The species figured 

 here, A. Goldieana, is a remarkable 

 native of old Calabar, West Africa. 

 It has a swollen woody root-stock, 

 from which the stems shoot up 

 annually. The large leaves are 

 heart - shaped, and the enormous 

 flowers (over a foot across) are of 

 brownish - red colour, mottled with 

 yellow, while the distended throat 

 is streaked with red and creamy 

 white. (Hot. May. t. 5672.)

This plant rarely flowers, but when 

 it does it excites attention. It must 

 be kept dry when in a dormant 

 condition, but water must be given 

 freely as growth commences and 

 increases. The atmosphere also 

 should be humid, and the night 

 temperature should not fall below 

 65 to 70 F.

A. Engleri. This is a handsome 

 plant about 6 ft. high, native of 

 Zanzibar. It grows partly submerged, 

 and has stems about 2 in. thick at 

 the base. The leaf-stalks are about 

 2 ft. long, with sheaths copiously 

 striped with black. The leaf-blade 

 is lj ft. long and about 1\ in. broad, 

 while the spathe is 2 ft. long and 6 

 in. broad. The fruit-bearing spadix 

 becomes as large as a child's head.

ARTHROPODIQM (arthron, a joint ; 

 pous, a foot ; the flower-stems being 

 jointed). Nat. Ord. Liliacese. A 

 genus containing about a dozen 

 species of plants with thickened 

 rhizomes or bulbous root-stocks, 

 and resembling the Anthericums in 

 appearance. They are easily grown 

 in a cool greenhouse in a compost of 

 sandy loam and peat or leaf -soil, 

 and may be increased by division, 

 offsets, and seeds. 



In the following species the leaves 

 are all radical, narrow or linear, and 

 the flowers, mostly white, are borne 

 in loose spikes during the summer 

 months. They are nearly all natives 

 of Australia or New Zealand, viz. : 

 A. drrhatum (Bot. Mag. t. 2350); 

 A. fimbriatum ; A. neo-caledonicum ; 

 A. paniculatum (Bot. Mag. t. 1421) ; 

 and A. pendulum (Red. Lil. t. 360). 



ARUM (aron, the Greek name for 

 the common species). Nat. Ord. 

 Aroideae. A genus of herbaceous 

 perennials with thick or tuberous 

 root-stocks, and pedate or hastate 

 leaves. Flowers monoecious, female 

 ones below, and separated from the 

 males by barren or rudimentary ones 

 on the more or less club-shaped 

 spadix. Berries fleshy. 



The Arums are a curious race of 

 plants, often with unpleasant odours 

 when in blossom, but nevertheless or-
