The firft of thefe Plants is Some- 

 times ufed in Medicine with us, as 

 is the third Sort in Germany : thefe 

 - are all Plants of no great Beauty ; 

 but as they will thrive in almoft any 

 Soil or Situation, they may be allow- 

 ed a Place in a fhady Border, for 

 Variety -fake. They all increafe a- 

 bundantly by their fpreading Roots, 

 which may be parted either in Spring 

 or Autumn ; as alfo by Seeds, which 

 ihould be foon after they are ripe. 

 They produce their Flowers for fe- 

 veral Months in the Summer, as in 

 May, June, July, and Augujl ; and 

 their Seeds ripen foon after. 



DORSTENIA [this Plant was fo 

 named by Father Plumier, from Dr. 

 Dorflen, a German Phyfician, who 

 publifhed an Hiftory of Plants in 

 Foliol, Contrayerva. 



The Characters are ; 



It bath a thick flejhy Placenta, 

 which is flat, and Jituated vertically ; 

 upon which are tlaced many apetalous 

 Flowers, which are fuceeedtd by 

 roundijh Seeds, fomewhat like thofe 

 ofGromwel, but /mailer. 

 The Species are ; 



1. Dorstenta dent aria r a dice, 

 fphondylii folio, placenta o<vali. Houfl. 

 Contrayerva with a Toothwort-root, 

 Cow- parfnep- leaf, and an oval Pla- 

 centa, 



2. Dorstenia dent aria r a dice, 

 folio minus laciniato, placenta- qua- 

 drangulari £ff undulata. Houfl. Con- 

 trayerva with a Toothwort-root, lefs 

 jagged Leaf, and a quadrangular 

 jindulated Placenta. 



3. Dorstenia fphondylii folio f er- 

 rata, placenta quadrangulari, radice 

 dentarifg. Contrayerva with a Tooth- 

 wort-root, fawed Cow-parfnep-leaf, 

 and a quadrangular Placenta. 



The firll of thefe Plants was dis- 

 covered by my late ingenious Friend 

 Dr. William Houfloun, near Old Vera 

 Cruz in New Spain. The fecond 

 was found, by the fame Gentleman, 

 on the rocky Grounds about Cam- 

 pechy. The third Sort was found 

 in great Plenty in the Ifland of To- 

 bago, by Mr. Robert Millar, Sur- 

 geon. But the Roots of all thefe 

 Species are indifferently brought 

 over, and ufed in Medicine, and 

 for Dyeing.* 



Thefe Plants are at prefent very- 

 rare in Europe, nor was it known 

 what the Plant was, whofe Roots 

 were imported, and had been long 

 ufed in Medicine in England, until 

 the late Dr. Houfloun informed us ; 

 for altho^ Father Plumier had dis- 

 covered one Species of this Plant, 

 and given the Name of Dorflenia to 

 the Genus ; yet he feems not to have 

 known, that the Contrayerva was 

 the Root of that Plant. 



It will be difficult to obtain thefe 

 Plants, becaufe the Seeds are feldom 

 to be found good ; nor will they 

 grow, if they are kept long out of 

 the Ground ; fo that the only fure 

 Method to obtain them is, to have 

 the Roots taken up at the time when 

 their Leaves begin to decay, and 

 planted pretty clofein Boxes of Earth, 

 which may be brought very fafe to 

 England ; provided they are pre- 

 ferved from Salt-water, and are not 

 over-watered with frelh Water in 

 their PafTage : when the Plants ar- 

 rive, they mould be tranfplanted 

 each into a feparate Pot filled with 

 frefli Earth, and plunged into the 

 Bark-ftove, which (hould be kept to 

 a moderate Heatj and the Plants
