gant White, and they have an agree- 

 able Odour ; but they feldom laft 

 longer than a Week in Beauty. 



The fifth Sort is a Native of the 

 warmeft Parts of America, where it 

 grows to the Height of thirty Feet, 

 having a large Trunk : the Branches 

 are produced irregularly on every 

 Side : thefe are cloathed with wing- 

 ed Leaves, which are generally com- 

 pofed of feven large roundilh Lobes, 

 each having a ftiort Footftalk. The 

 Flowers are produced on the Branches 

 before the Leaves put out : for in 

 their native Soil thefe Trees cart their 

 Leaves in the great Droughts ; where- 

 as thofe Plants which are preferred 

 in England, retain their Leaves 

 throughout the Year. 



This is a tender Plant ; fo will not 

 live through the Winter in England, 

 unlefs it is placed in a warm Stove. 

 It is propagated by Seeds, which 

 mould be fown in the Spring upon 

 an Hot-bed ; and, when the Plants 

 come up, they mud be treated in the 

 fame manner as hath been directed 

 for other tender Plants, and mould 

 be conftantly kept in the Tan-bed in 

 the warm Stove. There are fome 

 of thefe Plants in England ten Feet 

 high; but they have not produced 

 Flowers. This is call'd Dogwood 

 in America. 



RONDELETIA. 

 The Characters are ; 



It hath a falver-Jhap^d Flower, 

 conjijling of one Leaf which is tubu- 

 lous, and rejis on the Empalement ; 

 which Empalement afterward becomes 

 a roundijh coronated Fruit, divided 

 into two Cells, containing many fmall 

 Seeds. 



We know but one Species of this 

 Plant ; viz. 



Rondeletia arbor efcens, tini fa- 

 cie. Plum. Nov. Gen. Tree-like Ron- 

 deletia, with the Face of Laurus 

 Tinus. 



This Plant was difcover'd by Fa- 

 ther Piumitr in America, who gav« 

 it this Name in Honour to Guliel- 

 mus Rorideletius, a famous Phyfician 



of Montpelier. 



The Seeds of this Plant were fent 

 to England by Mr. Robert Millar, 

 Surgeon, who collected them on the 

 North Side of the Ifland of Jamaica, 

 where the Trees grow plentifully, as 

 alfo in feveral Parts of the Spanife 

 Weft-Indies. 



This Plant, being very tender, 

 cannot be preferv'd in England, un- 

 lefs it is kept in a warm Stove. It 

 is propagated by Seeds, which mould 

 be fown on an Hot-bed early in the 

 Spring ; and when the Plants are 

 come up, they mud be tranfplanted 

 into feparate fmall Pots, and plunged 

 into a moderate Hot-bed of Tan- 

 ners Bark, where they mull be treat- 

 ed in the fame manner as hath been 

 diredted for the Perefkia ; and in 

 Winter muft be plac'd in the Tan- 

 bed in the Stove, where thefe Plants 

 will thrive, and in two or three 

 Years will flower ; when they will 

 make an agreeable Variety amongft 

 other tender Exotic Plants.
