cup. Bulbosus is the Crowfoot, a troublesome garden weed with 

 great tenacity of life, best extirpated by uprooting it while the soil 

 is moist. Ficaria is the Lesser Celandine. The following are good 

 garden species and varieties: aconitifolius plenus (Fair Maids of 

 France), double white flowers in late spring, height about 18 ins.; 

 amplexicaulis, white, spring, 9 ins. (Botanical Magazine, t. 266); 

 Lyalli, white, spring, 2 to 3 ft. Asiaticus has given us the florists' 

 Ranunculus. See Bulbs. 



Rape (Brassica Napus). Often sown to accompany Cress as a 

 substitute for Mustard, and may be treated like the latter. Rape 

 dust, the refuse of the seed, may be dressed into ground infested 

 with wire worm. 



Raphanus. See Radish and Kitchen Garden. 



Raffia or Raphia. A cheap, strong, and flexible tying material, 

 sold by florists; it is prepared from the hothouse palm, Raphia 

 pedunculata. 



Raspberry (Rubus Idaeus. Ord. Rosaceae). See Fruit. 



Raspberry-Blackberry. A cross between the two fruits named. 

 Culture as for Blackberry. See Fruit. 



Rat's-tail Cactus, Cereus flagelliformis. 



Red Cedar, Juniperus Virginiana. 



Red Gum, Eucalyptus resinifera. 



Red Spider. Tetranychus telarius is one of the most troublesome 

 of plant enemies, attacking both indoor and outdoor crops. It is 

 really a sucking mite, not a true spider, although it spins a web on 

 the under side of the leaves. When the leaves of Grape Vines, 

 Peaches, Cucumbers, Scarlet Runners, and many other plants 

 which might be named turn bronzy or yellow before the natural 

 period of decay, red spider may be suspected. A dry atmosphere 

 encourages it, a moist one is inimical to it. Frequent syringing is 

 a preventive. In case of emergency, syringe with hot water in 

 which soft soap at the rate of i lb. per gallon and sulphur i 

 handful per gallon have been stirred; or dust with flowers of 

 sulphur. 



Rehmannia (rehman-nia, after Dr. Rehmann. Ord. Scrophulari- 

 neae). Handsome herbaceous perennials, nearly hardy, but best 

 grown in a cool house. They are not particular as to soil, and are 

 propagated by cuttings in spring. 



Renanthera (renanthe-ra, from ren, a kidney, and anther a, an 

 anther, in allusion to the form of the anther. Ord. Orchidaceae). 

 A small genus of Orchids. Coccinea grows 4 to 5 ft. high, has red 

 flowers, and looks well trained against a fern stump in a hothouse, 

 also in a basket (see the Botanical Magazine, tt. 2997, 2998). Im- 

 schootiana has red and yellow flowers, and is also a good basket 

 plant. They thrive in peat and Sphagnum moss, with sand and 

 charcoal, and may be increased by cuttings in a propagating case. 



Reseda, Mignonette (rese-da, from resedo, to calm, on account of 

 soothing qualities being ascribed to it. Ord. Resedaceae). See 

 Mignonette and Annuals.
