APIOS. (GROUND NUT.) 



A genus of four twining perennials (prd. Legum- 

 inos;r), only one of which is in commerce. They 

 have tuberous roots and purplish flowers. In- 

 creased by division of the tuberous roots. A light, 

 warm soil and a sunny sheltered position, with a 

 trellis or shrub to climb over, are the principal 

 requirements of the Apios. Plant the tubers in 

 spring and mulch in winter. 



Principal Species : 



tubenw.-i. climbing, Jy., etc., hdy., br. pur. A 

 graceful twiner with Pea-shaped flowers. In its 

 native habitats in Canada and the United States 

 it grows in moist soil (syiis. Glycine Apios, 

 Apios Apios). 



APIUM. 



r.i'-nnial hardy herbs, or perennials (prd. Um- 

 bellil'eras) of no horticultural value except in the 

 case of Celery, which see.

APLECTRUM. 



A terrestrial Orchid (ord. Orchidacea?) having a 

 tuberous rootstock, and succeeding in the open air 

 in tliis country if planted in shady spots in suitable 

 soil, as in the case of Trillium. Propagation is by 

 offsets from established clumps. A compost con- 

 sisting chiefly of peat, leaf soil and sand should be 

 prepared to replace the natural soil in shady situa- 

 tions. 



Principal Species :

APOCYNUM. (DOG'S BANE.) 



Hardy herbaceous plants (ord. Apocynacess) of 

 easy culture, with numerous small flowers. Propa- 

 gated by seeds. Or division of the clumps in 

 March or April, when growth is commencing, will 

 readily give all the stock required. Any well- 

 drained garden soil will suit. 



Principal Species :

Aug., pale red with pus).

APODOLIRION. 



A genus of six species of bulbs, including 

 Gethyllis lanceolata, allied to Cooperia, and be- 

 longing to the order Amaryllidea:. Leaves linear 



like those of a Crocus, as is the white, reddish, or 

 rose flower which nestles among the leaves. They 

 are propagated by offsets, and require greenhouse 

 treatment in a compost of light sandy loam and 

 peat. Keep them dry while resting in winter.

APONOGETON. 



Interesting and beautiful stove or hardy aquatic 

 plants (ord. Naiadacese) worthy of increased culti- 

 vation. Increased by division or seeds. Loam, 

 leaf soil, and a little gritty sand, suit them. The 

 tender species thrive in small tanks under glass, 

 where a winter temperature of 60 to 65 is main- 

 tained, rising in summer to about 10 more. The 

 hardy species can be grown in ponds, small tanks, 

 and tubs in the open air. The latter increase very 

 rapidly, and require occasional division to prevent 

 overcrowding. A depth of water of from 1' to 

 1J' is most suitable. 



Principal Species : 



angustifolium, pk., bracts wh. A grh. plant of 

 considerable beauty. 



distachyon, Je., etc., wb. The Cape Pond 

 Weed, or Water Hawthorn. A charming hdy. 

 aquatic with a delicious fragrance. There are 

 several varieties, few being as hdy. as the type. 

 The variety monostachyon, formerly considered a 

 separate species, requires a St. temperature. Sep., pk. 



Legrangei, wh., ro. bracts. 



roseum, ro. 



fenestrale, Aug., grn. The Lattice or Lace-leaf 

 Plant. Its beauty consists in the lace-like leaves, 

 which are much admired (syn. Ouvirandra 

 fenestralis.) 



spathaceum junceum, half-hdy., blush. 



Other Species : 

 berneriauum, Aug., st., pk. crispum, Aug., st., wh. 



APPENDICULA (nyns. COSCHOCHILUS 

 and METACHILUM). 



Epiphytal Orchids (iird. Orchidacese) with 

 leafy stems, often compressed, or two-edged, and 

 bearing short racemes of small or minute flowers 

 in the axils of the leaves, and often towards 

 the apex of the stems. They are propagated by 

 division or by offsets. For compost use fibrous 

 peat and chopped sphagnum with plenty of 

 drainage. Grow them in the East Indian house. 



Principal Species : 



peyeriana, 1' to 1' 6", st., wh. 



APPLE. 



Description. One of the most useful and 

 profitable hardy fruits (ord. Rosacese). In the 

 form of the Crab it grows wild in Britain, but it is 

 generally supposed that the race of varieties grown 

 in this country was introduced, at different times, 

 from the continent. 



Propagation. By seeds, cuttings, and layers ; 

 also by budding and grafting on various stocks. 

 For commercial purposes the last two are the 

 methods generally adopted. 



Stocks. There are several different stocks used, 

 and the best for dwarf trees which are desired to 

 come quickly into bearing is the broad- leaved 

 English Paradise, a dwarf variety of Pyrus Mains of 

 bushy habit, producing masses of fibrous roots near 

 to the surface of the ground. The stocks are 

 chiefly obtained by layering and pegging down the 



Apiirum (see Detulrobium).
