R U 



comes from the fame Country ; there- 

 fore thefe three fhould be planted in 

 Pots, and (helter'd in Winter from 

 fevere Froft ; but they mult have 

 free Air in mild Weather. 



All thefe Plants may be propagated 

 either by fowing of their Seed?, or 

 by planting Slips or Cuttings; both 

 of which muft be done in the Spring. 

 The manner of propagating them 

 from Cuttings being the fame with 

 Rofmary, &c. I mall not repeat it 

 here, but refer the Reader to that 

 Article ; and if they are propagated 

 by Seeds, there needs no farther Care 

 but to dig a Bed of frefh Earth in 

 the Spring, making it level ; then to 

 fow the Seeds thereon, and rake the 

 Ground fmooth : after which you 

 muft obferve to keep the Bed clear 

 from Weeds until the Plants are 

 come up about two Inches high ; 

 when they mould be tranfpianted out 

 into frelh Beds, where they may re- 

 main for Ufe. All thefe Plants muft 

 have a dry Soil, otherwife they are 

 very fubject to be deftroy'd in Win- 

 ter. The two Aleppo Rues, and the 

 wild Rue, are fomewhat tenderer 

 than the common Sort ; but thefe 

 will endure our ordinary Winters 

 very well in the open Air, efpecially 

 if they are planted on a dry Soil. 



The firft Sort was formerly ufed 

 to plant for Edgings on the Sides of 

 Borders ; it was then called Herb of 

 Grace ; but was by no means pro- 

 per for this Ufe j for the Plants 

 ihoot fo vigoroufly, that there is no 

 keeping them within the Bounds of 

 an Edging ; befides, when they are 

 kept clofely mear'd, they appear 

 very ragged and ftumpy ; and their 

 Roots fpread fo far, as to exhauft the 

 Goodnefs of the Soil, fo that the 

 other Plants would be deprived of 

 their Nourimment j which Reafons 

 have caus'd them to be wholly neg- 

 lected for this Purpofe ; fc that at 



R U 



prefent they are chiefly cultivatej 

 for medicinal Ufe, or to furnifh the 

 Balconies for the Citizens in the 

 Spring. 



RUTA CANINA. Vide Scro- 

 phularia. 



RUTA MURARIA, Wall-rue, 

 or White Maiden-hair. 



This Plant is found growing out 

 of the Joints of eld Walls in divers 

 -Parts o{ England, where it is gather 'd 

 for medicinal Ufe ; but as it cannot 

 be cultivated in Gardens, fo as to 

 grow to Advantage, I fball not fay 

 any thing more of it in this Place. 



RUYSCHIANA. 

 The Characters are } 



It hath a lahiated Flower cgv fif- 

 ing of one Leaf whofe Upper-lip ( or 

 Creft J is divided into two Parts ; but 

 the Beard is cut into three Segments^ 

 the middle Segment being divided into 

 two Parts, and is twijled like a Screw: 

 out of the Empaiemcnt arifes the Poin- 

 tal t fixed like a Nail in the hinder 

 Part of the Flower, attended by four 

 Embryoes ; which afterward become 

 fo many Seeds inclofcd in the Empale- 

 ment. 



We have but one Species of this 

 Plant ; which is, 



Ruyschiana fore cceruleo ma- 

 gno. Boerh.Ind. alt. Ruyfchiana with 

 a large blue Flower. 



This Name was given to this 

 Plant by the learned Dr. Boerbaave, 

 ProfefTor of Botany at Leaden, in 

 Honour to Dr. Ruyfcb, who was Pro- 

 fefTor of Anatomy and Botany at Am- 

 fierdam. It was by fome Writers in 

 Botany ranged among the Hy flops ; 

 by others it was made a Ground- 

 pine ; and by fome a Self-heal ; to 

 neither of which it exactly agreed: 

 which occafion'd Dr. Boerhaave to 

 conftitute a new Genus of it by this 

 Name. 



This is a perennial Plant, which 

 dies to the Root in Autumn, and rifes 



again
