 growing, to keep Red Spider in check. 



Rhododendrons. 

 — The javanico jasmini- 

 Jiorum hybrids form a 

 group of this gorgeous 

 family well adapted for 

 cultivation in the cool 

 stove or intermediate 

 house, and where a col- 

 lection is kept some of 

 their lovely flowers are 

 thus obtainable all 

 through the year. They 

 range from almost pure 

 white through handsome 

 shades of orange, yellow, 

 pink, rose, and brilliant 

 scarlet. Cuttings of half- 

 ripened wood strike 

 tolerably freely in heat in a propagating-case, and the plants 

 thrive in fibrous peat and sand with good drainage. 



Rivina humilis. — A pretty little West Indian plant, producing 

 racemes of rosy flowers, succeeded by little bright scarlet berries. 

 It is readily raised from seed or cuttings, and delights in a 

 compost of equal parts loam and leaf-mould with the usual dash 

 ■of silver-sand. 



Rondeletia. — Stove evergreen shrubs from the West Indies 

 and Tropical America, with opposite leaves and fragrant flowers 

 in terminal corymbs. Propagate by cuttings and grow in fibrous 

 peat and loam with a few lumps of charcoal and a dash of 

 sand. Tie out the shoots to neat stakes. Sorts : R. cordata, 

 rose-coloured ; R. gratissima, carmine and very sweet-scented ; 

 R. speciosa (odorata), bright vermilion, salver-shaped, with a 

 yellow centre ; and R. speciosa major, a form with larger flowers 

 than the type. 



Russelia juncea. — This is a somewhat singular-looking plant 

 from Mexico. It grows about 3ft. high, with very small leaves, 

 and these only sparingly produced. The slender, angular, rush- 

 like branches hang out gracefully, producing at various seasons 

 rich crimson tubular flowers, which droop in an elegant manner. 

 It is of very easy culture, growing freely in peat, loam, and 

 sand, and is readily propagated by cuttings, or by allowing a 

 branch to lie on the moist soil, where it will soon throw out roots, 

 and may then be cut off and planted in a fresh pot of compost 



Saintpaulia ionantha is a charming little plant of somewhat 

 jecent introduction from East Africa. It is easily raised from
