DOUBLE O RIF LAM ME. 
O Riflamme is a Name given, long firice, to a fpecious fingle Tulip, from 
its Colours which were fuppofed to imitate thofe of the antient facred 
Banner of the French j whofe Tints were Blood and Gold. I do not 
know, that before this Year, it has been feen double^ This was the happy Ef- 
fect of a regulated Culture ; it was rais’d in England, and is added to the 
Plants of this Collection, not alone for its Beauty^ but becaufe it will ferve 
very happily to explain the Coufle of Nature in doubling the Bulbous rooted, 
Hexandrous Flowers. 
The Leaves, the Root, and the whole AfpeCt of the Plant are the fame 
with thole of the fingle Tulip from which it fprings 5 but the Stalk is Ihorter. 
This confirms the Opinion advanc’d before in fpeakingof the Rofeate NyCtan- 
thes, that the Force of Nature burfting into Bloom, at a lefs Growth in Height 
than ufual, favours the Doublenefs of Flowers : more Petals being form’d, be- 
caufe there is more Nourifhment fent thither. 
In this Plate we fee the fingle arid the double Flowxr together, and as the 
Parts are all large and confpicuoiis, we fhall trade without great Difficulty how 
the Change is made. Double Tulips have hitherto been flighted, becaufe they 
were irregularly doubled, and rofeas Chance direCIed : this will perhaps bring 
them into repute, and the Gardener rhay have them thus regularly double, if 
he w‘ill follow the Method of a proper Culture. 
The fingle Tulip confifts of three Parts: the Petals or Leaves which are fix, 
the Filaments with their Buttons alfo fix, and a fingle Rudiment of a Seed-vef- 
fel. Thefe are confpicuous in the fingle Flower 5 in the Double the fix outer 
Petals, and the Rudiment of the Seed-veflfel remain unalter’d, therefore the 
Change is not made from them : but the fix Filaments are loft entirely. There- 
fore Reafon fays the additional Petals are made out of the Filaments : and this 
Experience confirms. 
The Doublenefs of a Tulip will be favoured by this Cultute. When the 
fingle Tulip is in the Bud, juft before it would have open’d, cut it down. 
Water the Root Hightly, Morning and Evening, and at the ufual Seafon take 
it up. Plant it again with Marie in the Mould, and the next Year ufe the 
fame Caution, many may be thus manag’d at once, for a few only will come 
double, as is the Cafe in Anemones and many other Flowers. Of thefe fuch only 
asffiew a Tendency to Doublenefs the fecond Year, are to be treated thus, the 
following, and fo on for the fucceeding Seafons. This firft Tendency to Dou- 
blenefs, is to be feen in the Filaments, they grow broader and more flat. 
After this, it comes on thus : the Filaments grow broader and fplit like Forks, 
the Button ftadding in the Middle of the Divifion : then, in the fucceeding 
Years, the new Petals grow broader, and the Points wear olf ; at Length the 
Rudiment of the Button alfo fades away, and there are then fix new Petals like 
the fix firft : after this, each Iplits flatwife into two, and they become twelve, 
fo that the Flower confifts of eighteen Petals with no Remains of Buttons. This 
is the perfe6b double Tulip.
