412 Select Plants for Industrial Culture and 



four feet [J. R. Jackson], is regarded by Dr. Th. Anderson as a 

 mere variety, and he thinks, that all have sprung from the ordinary 

 R. Raphanistrum, L., of Europe. Indeed, R. maritimus seem also 

 a primitive form of the coast, with a root of fine quality and 

 great pungency [Chambers.] All radishes succeed best in a 

 calcareous soil, or their culture must be aided by manure rich in 

 lime. The root of the black radish is comparatively rich in starch. 

 The seeds, according to Vilmorin, will keep about five years. 



Remirea maritima, Aublet. 



Intra-tropical coast-regions around the globe. A perennial 

 creeping sedge for binding sand. Hardy a considerable distance 

 beyond the tropics. 



Reseda Xmteola, Limn'. 



The Weld. Middle and Southern Europe, Middle Asia, North- 

 Africa. An herb of one or two years' duration. Likes calcareous 

 soil. A yellow dye (luteolin) pervades the whole plant. The plant 

 must be cut before the fruit commences to develop, otherwise the 

 pigment will much diminish. 



Reseda odorata, Linne. 



The true Mignonette. North -Africa and Syria, A favorite 

 garden-herb of one or very few years' duration. Ripens in West- 

 Europe ; seeds still in lat. 69 18'. About 40,000 Ibs. are annually 

 gathered at Grasse for distillation, the price being about lOd. a Ib. 

 The delicate long enduring scent can be concentrated and removed 

 by enfleurage, or better still in Blogg's process by methyl chloride, 

 fixed as so-called " concrete oil.'' To be counted also among the 

 honey-plants. Mess. Dippe in Quedlinburg devote regularly about 

 50 acres to rearing of mignonette-seeds. 



Rhagrodia Billardieri, E. Brown. 



Extra-tropical Australia. An important bush for binding moving 

 sands on sea-shores. Resists the severest gales as well as the spray 

 of the sea. Browsed on by pastoral animals. 



Rhag-odia nntans, E. Brown. 



Southern, Eastern and Central Australia. This is a good fodder- 

 herb for saltbush-runs. R. linifolia is similarly important [Alex. 

 Hamilton]. Further may be mentioned R. spinescens (R. Brown), 

 the spineless variety of which is greedily eaten by horses, cattle 

 and sheep, according to Mrs. Biddulph. The rather tall and bulky 

 R. hastata (R. Br.) is equally valuable [Rev. Dr. Woolls]. Mr. 

 W. A. Dixon found the proportion of saline substance in this plant 

 very large. Several other species deserve attention. Some other 

 species, mostly shrubby, are equally valuable.
