The Rrfl: fort is a common weed in men: of the low 

 pailures and meadows in many parts of England 

 whtrrc it is one of the m.oft troublcfome weeds among 

 the Grafs, fpreading itlclf over the whole ground, lo 

 that in many of the water meadows, there is more 

 of this plant than Grafs. It is an annual plant, which 

 flowers the latter end of May, fo that the feeds ripen 

 by the time the Grafs of thefe meadows is mowed, 

 and the feeds fcatter and fill the ground with young 

 plants the following fpring ; therefore, in order to 

 dedroy it, the Grafs fliould be cut as foon as the 

 flowers of this plant appear. 



It is well known, fo requires no defcription ; and as 

 it is never cultivated, fo it is mentioned chiefly to in- 



; but here I muftobferve, that the 

 Dutch carry on a trade with the feeds and feed-veflels 

 of one fpecies of this genus to Germany, whofe feed- 

 veffels appear very like thofeofthis firft fort, they 

 call it Semen Savadillos -, the ufe of it is to kill ver- 

 min of every fort, efpecially bugs ; they boil a quan- 

 tity of the feeds and capfules in common v/ater, with 

 which they wadi their wainfcots, bedfteads, &c. 

 where any of thefe infects are lodged, and it efFedu- 

 ally dcftroys them. 



The fecond fort was difcovered by Dr. Tournefort on 

 the fides of the Black Sea, growing in a fat foil and 

 fiiady fituation. The flower being fhaped like an 

 Elephant's-head, induced Fabius Columna to give 

 the title of Elephas to^the third fpecies, which he 

 found growing naturally in the kingdom of Naples, 

 and Tournefort after him efl:abliflied the genus with 

 that title. The ftalks of this rife a foot and a half

ftaiks ; they are about two inches long, and half an

The upper part of the ftalk is garniftied with flowers 



growing oppoflte from the wings of the leaves v tHefe

 This genus of plants is ranged in the feventh feftion 

 of Linna^us's twenty-fccond clafs, wliich contains 

 thofe plants whofe male and female flowers are upon 

 different plants, and the male flowers have ciahc lla- 

 mina. 



The Species are, 



1. Rhodjola (Rofea) ftaminibus corolla duplo lon^io- 

 ribus. Rofe-roGt ivitb ffamina ti^ice as long as the petals, 

 Anacampferos radice rofam fpirante major. Tourn.

2. Rhodiola {Miner) fl:aminibus corolla fere ^squanti- 

 bus. Rofe-rcDt 'u.ithfiamina fcarcely equalling the length 

 of the petals. Anacampferos radice rofam fpirante mi- 

 nor. Tourn. Inft. R. H. 264. Smaller Orpine v:itb a 

 RofC'fcented root. 



The firfl: fort grows naturally in the clefts of the 

 rocks and rugged parrs of the mountains of Wales, 

 Yorkfliire, and Weftmoreland. This has a very thick 

 fleftiyroot, which, when bruifedor cut, fends out an 

 pdour like Rofes; it has many heads, from whence 

 in the fpring come out thick fucculent ftalks like thofe 

 of Orpine, about nine inches long, clofely garniflied 

 with thick fucculent leaves of a gray colour, which 

 are an inch long, and half an inch broad, indented 

 on their edges toward the top, and are placed alter- 

 nately on every fide the fl:alk. The flialk is termi- 

 nated by a clufter of yeliowifli herbaceous flowers, 

 which appear early in May ; the male flowers have 

 ftamina twice the length of the petals. They have 

 a very agreeable fcent, but are not of Ions; conti- 

 nuance. ' . . 



t^vCThe fecond fort grows naturally on the Alps j the 

 ^ roots of this are fmaller than thofe of the other fort, 



. the ftalks arefmal], and not above five inches loner ; 

 the leaves are fmall, but ihaped like thofe of the other 

 fort, and end with a purple point; t^e^ petals of the 



;-, flowers are purplifh, ana the ftamina are but Iktle 

 - longer than the petals. This flowers later than the 



^.^other fort, % I have cultivated both thefe' plants in the 



. • fame foil above thirty years, and have never found ei-, 



^: ther of them vary. ■ . 



"Thefe plants are preferved in the gardens of the cu- 

 . rious, ■ for the fake of variety ; they are eafily propa- 

 gated, either by cuttings or parting of the roots. - If 

 by cuttings, they fliould be planted the beginning of 

 April, foon after they come out from the head ; if 

 thefe are planted in a Ihady border, and covered clofe 

 down with a glafs, keeping them dry, they will put 

 out roots in about fix weeks ; but the cuttings fliould 

 be laid in a dry room at leaft a week before they 



., ^are planted, that the wounds may be dried before 



;..;: they are planted, otherwife they are fubjeft to rot. 



.,vvlf they are propagated by parting of the roots, that 



jfhould be'performed in the beginning' of September, 



%^ at which time their ftalks begin to decay; and if the 



/:%fliy parts of the roots are cut or broken, they ftiould 



be laid tq^dry a fe\ydaxs before they are planted, for 



the fame reafon a's the cuttings. Thefe plants require 



...a fliady fituation and a dry undunged foil, in which 



i they will continue many years
