Soil. Rich loam, with abundance of manure and 

 vruter. TIio soil should be deeply trenched, and

 manure water in summer are beneficial. (>St also

RHEXIA. 



Erect herbs and sub-shrubs (ord. Melastomaceae). 

 Two are showy hardy herbaceous plants that are 

 well worth a place in all gardens. Propagation, 

 by division. Soil, peat, or one containing a good 

 deal of leaf mould. Several species are now 

 referred to Tibouchina.

RHINACANTHUS. 



Loosely brandling, occasionally semi-scandent 

 shrubs (ord. Acanthacea;), of little garden value. 



RHINANTHUS (//. ALECTOROLOPHUS). 



Upright, hardy annuals (ord. Scrophularinere), 

 of no special garden value. They are more or less 

 parasitic on the roots of Grasses in damp pastures. 

 Propagation, by seed. Any moist soil will do. 



Principal Species : 



Crista-galli, 6" to 18", sum., yel. ; British. Penny 

 G'-ass, Yellow Rattle. 



RHIPOGONUM. 



Greenhouse, evergreen climbers (ord. Liliacefe). 

 Propagation, by cuttings of side growths in late 

 spring, beneath a bell-glass, over mild heat. Soil, 

 fibrous loam, peat, and plenty of sharp sand. 



Principal Species : 



album, 3', Je., wh. scandens, 2', Je., wh. 



(ni/n. parvifiorum). 



RHIPSALIS. (MISTLETOE CACTUS.) 

 Curious succulent shrubs (ord. Cacteoe), whose 

 nearly leafless stems assume various shapes. The 

 flowers of several species are showy. The fruit is 

 inurh like that of the Mistletoe. Propagation, by 

 cuttings, dried in the sun for a few days before 

 being inserted in sandy or gravelly loam, to root. 

 Soil, sandy loam two parts, and leaf mould and

RHIZOGLYPHUS. 



A species of Rhizoglyphus causes much damage 

 to Eucharises, and is known to gardeners as the 

 Bulb Mite. It also attacks Snowdrops, and numbers 

 of other Amarylliclaceous plants. Yellowing foliage 

 and premature death are tbe signs of infestation 

 (SIT EUCHARIS). Badly infested Snowdrops are 

 best burnt out of hand. 



RHIZOPHORA. (MANGROVE} 



Tropical sub-aquatic trees (ord. Rhizophorese). 

 The interest attaching to them is very considerable. 

 They are to be found on sea shores, mud banks, 

 and swamps, and frequently form impenetrable 

 fringes. The seeds germinate upon the parent plants, 

 and fall when they are furnished with roots and 

 have attained to considerable size. The Mangrove 

 is of the highest importance, as it assists to re- 

 claim land from the sea. The network of roots 

 and stems catches and holds vast quantities of 

 vegetable matter, which ultimately becomes more 

 or less solid ground. The fruit of Mangle, the 

 chief species, is edible, and by fermenting it a 

 kind of wine is obtained. 



RHODAMNIA (*</. MOSOXORA). 



Stove or greenhouse shrubs (urd. Myrtaceas), 

 with opposite flowers and broadly lanceolate leaves. 

 Of no special garden value. 



RHODANTHE. 



Charming greenhouse or half-hardy annuals (ord. 

 Compositse). The cultural conditions are simple. 

 Seeds may be sown in spring and onwards for 

 succession. They may be sown in a pan and the 

 seedlings transplanted, or in a 5" pot and the 

 seedlings thinned to 2" apart. The young plants 

 will need supporting by stakes round the outside, 

 and two or three circling bands. Green fly is very 

 fond of Rhodanthes, and must be kept down, or 

 the plants will be badly crippled. Except for this 

 there is no trouble in their culture.
