LIST OF FLOWERS 



RAGGED ROBIN. See Lychnis. 



RANUNCULUS (Buttercup). Among the cultivated species 

 R. alfestris, the Alpine Buttercup, makes a good plant for the Rock 

 Garden if set in a moist and porous soil. It grows in small tufts, 

 and its large flowers of pure white, borne singly on erect stems, form 

 an attractive contrast to its mass of shining dark-green leaves. R. 

 amplexicaulis is another species well suited for the Rock Garden. 

 It grows about i foot high, with grey-green leaves, slender stems 

 and flowers of pure white with yellow centres. R. asiaticus, the 

 Turban Ranunculus, is a garden variety of which there are many 

 sorts and many colours, all of some value. It is less delicate than 

 some of the named varieties of the garden Ranunculus, and in a 

 well-worked soil and open situation it thrives well. The bulbs 

 should be planted in the latter half of February, claw downwards, 

 about 2 inches deep, and as soon as the leaves fade, after flowering, 

 the bulbs should be lifted and stored in a cool place in sand, as they 

 seldom withstand the coldrains of winter though delighting in warm 

 moisture. 



RED-HOT POKER PLANT. See Kniphofia. 



RESEDA-ODORATA. See Mignonette. 



REST HARROW. See Ononis. 



RHODANTHE. A half-hardy annual, one of the brightest of 

 " Everlasting " flowers and useful also for the garden border. R. 

 Mangiest is the original species, and has rose-coloured blossoms with 

 yellow centres, while R. maculata may be had with either white or 

 carmine flowers. R. atro-sanguinea differs from the foregoing by 

 being more branched and of dwarfer growth, and bears flowers of 

 bright magenta, but it is somewhat tender. Seed should be sown 

 in heat in February or March, and the seedlings pricked off as soon 

 as possible, as they do not transplant successfully except when quite 

 small. 



RICHARDIA. There are several species of this genus, but that 

 which is generally known and cultivated with us is R. cethiopica, 

 commonly called the Arum Lily or the LUy of the Nile. The latter 

 name is certainly a misnomer, the plant not being found anywhere 

 near the Nile, though it may be seen in profusion, growing rampantly 

 wild, throughout the Cape. Its handsome white spathes and fine 

 foliage make it an effective plant for the greenhouse, and it may be
