and shallow rooting crops being alternated. Crops 

 in which the roots are used, such as Turnips, 

 Beetroots, Parsnips, etc., should not follow each 

 other, but be divided by Beans, Peas, or Cabbages. 

 Celery might be succeeded by Beans or Peas, and 

 these again by Potatoes, followed by Cabbages or 

 Cauliflowers, and these again by root crops. 



ROTHIA. 



Two species of dwarf, spreading annuals (ord. 

 LeguminosiB). Propagation, by seeds, ; n sheltered 

 parts of the garden, in rather light soil. 



Only Species Introduced : 



trifoliata, 2', Jy., sulphur. 



rose flowers in terminal heads. Propagation, by 

 cuttings of side shoots, getting firm, in sand in a 

 propagating case, with a fairly dry atmosphere. 

 .Soil, equal parts fibrous loam and peat, with 

 plenty of sand. Grata flowers best when planted 

 in a brick pit or narrow border to confine the 

 roots. Train the shoots to the rafters. The roots 

 must be kept rather dry in winter. 



Only Species : 



grata, >' to 20', My., pk. or flesh, very fragrant.

ROUREA. 



Stove shrubs (ord Connaracere). Propagation, 



ROTHMANNIA 



RANDIA). 



GARDENIA and 



ROUPALA (syns. RHOPALA and ROPALA). 



Stove trees (ord. Proteacese), grown only in the 

 juvenile state as fine foliage plants. At this stngc 

 the leaves are pinnate and smooth or rusty woolly. 

 Propagation, by cuttings of mature wood in sand, 

 under a bell-glass, and kept dry overhead. After 

 some weeks, rooting may be hastened by plunging 

 the pots in bottom heat. Soil, equal proportions 

 of fibrous loam and peat, with sand. 



Principal Species : 



:iurea, Ivs. with gold felt, 

 elegans, Ivs. slender. 

 Pohlii,6'to20', Ivs. with 



rusty or. felt (.<(/. cor- 

 eovadeusis).

reddish br. felt.

 aceie), sometimes climbing, bearing white or 



Itiittlera. of Roxburgh (see Mallotiis). 

 Houge Plant (see, liivina Tiumilu). 

 Ronliamon (sec Strydinos). 



by cuttings in sand, in heat. Soil, fibrous loam, 

 with a third of peat, and sand. 



Principal Species : 

 frutescens, 6', wh. (syn. fulgeus, 4' to ">', red. 



Robergia frutescens) . 



ROYDSIA. 



Shrubs (ord. Capparidece), with fragrant flowers. 

 Fruit Olive shaped, red. Propagation, by cuttings 

 of side shoots in sand. Soil, fibrous, mellow loam, 

 with plenty of sand. 



Principal Species : 



suaveoh'iis, Jan., My., dull red, yel., racemes or 

 panicles 3" to 7" long, free flowering. 



ROYENA. (CAPE SNOWDROP.) 

 Greenhouse evergreen shrubs (ord. Ebenacese). 

 Propagation, by cuttings of shoots, getting firm, in 

 sand, under a bell-glass. Soil, mellow loam and 

 good peat, half and half, with sand.
