tiff us, it hath been altered by Dr. 

 I'un Roy en, Profeflbr of Botany at 

 Ley den, to Ny3agt, from the Flow- 

 ers opening in the Night. 

 The Species are ; 



1. J ala PA flare flaw. Tourtt.

2. Jala pa flore purtureo. Tourn. 

 Jalap, or Marvel of Peru, with a 

 purple Flower. 



3. Jalap a flore ex a Iki do. To urn. 

 Jalap, or Marvel of Peru, with a

4. Jalap a flore ex rubra, luteo, 

 & a/60 mixta. Tourn. Jalap, or Mar- 

 vel of Peru, with red, yellow, and 

 white Flowers mix'd upon the fame 

 Plane. 



5. Jalapa flore ex albo & fur-

6. Jalapa parvo flore. Tourn. 

 Jalap with a fmall Flower. 



7. Jalapa oflicinarutn, fruStu ru~ 

 gofo. Tourn. Tne fuppofed true Ja- 

 lap of the Shops, with a rough

Thefe Plants are all propagated 

 by Seeds, which mould be fown up- 

 on a moderate Hot-bed in March ; 

 and when they come up, they mould 

 be tranfplanted into another Hot- 

 bed, at fix Inches Diicance from each 

 other ; and when they have taken 

 Root, the GlafTes muft be raifed 

 every Day, that the Plants may 

 have a great deal of Air, ocherwife 

 they are very fubject to be drawn 

 up tall and weak; nor can they be 

 recovered to a fufiicient Strength 

 again in a ^Month's time, if once 

 they are thus drawn. When the 

 Plants are grown to be a Foot high, 

 , they mould be put into Pots filled 

 with rich light Earth, which mould 

 be plunged into a very moderate 

 Hot-bed, to facilitate their taking 



Vouir.

Root : and in removing them yoi 

 muft be very careful to prefer ve ai 

 much Earth to their Roots as you 

 can ; for their Roots have but few 

 Fibres to retain it inaBall, as many 

 other Plants will do : and it fome- 

 times happens, when the Root is 

 left bare, it feldom takes frefh Hold 

 of the Ground^ at leal! not in a con- 

 fiderable time; fo that the Plant* 

 will make but a poor Figure that 

 Seafon. When they are tranfplant- 

 ed into the Pots, and have taken 

 Root again, they lhould be harden- 

 ed to endure the open Air, for they 

 are not very tender ; but, on the 

 contrary, they will not thrive well, 

 if too much drawn or forced in the 

 Hot-bed. In the Middle of May 

 the Pots may be removed into the 

 Places where they are defigned to be 

 continued for that Seafon ; obferving 

 to fupp ort the Branches w.th a ftrong 

 Stake, and to water them as often 

 as they require it. You may alfo in 

 May plane fome of them into the 

 Middle of the large BjrJets of the 

 Pleafure-gardcn, doing it carefully, 

 and obftrving to made and water 

 them until chey have taken Root ; 

 after which, they will require no 

 farther Care but to fupport thern 

 from being broken down by the 

 Winds, which they are very lubjedt 

 to be, efpecially when their Heads 

 are large. 



The Plants, thus raifed, will grow,- 

 to the Height of three or four Feet, 

 and fpread their Branches very wide 

 (efpecially if the Roots have room 

 in the Pots) ; their Flowers will be- 

 gin to appear in June, and they will 

 continue conltantly flowering until 

 the Froft prevents them ; which, 

 together with the great Diverfity of 

 Colours in the Flowers upon the 

 fame Plant, renders them valuable 

 to every curious Perfon. The Mow- 

 ers of thefe Plants never expand in
