The Characters are. 

 The empalement of the fic-wer is permanent, erei'l, and 

 cut into five parts. The flozver has five oval, ere£i^ 

 fpreading petals, and^ five JJjcrt Jlamina terminated by 

 fmall fummits, floor ter than the petals ; // has a round- 

 iflo gerrnen as large as the petals, with fc^*-^^ ^"^ ^-/-^

The iirll fort grows naturally on the Alps, and alfo 

 upon feveral mountains in Italy. This is a low fllrub, 

 which feldom rifes two feet high, fending out many 

 fhort ligneous branches, covered with a light brown

bark, and garniflied clofely with oval fpear-fhaped 

 leaves about halt an inch Jong, and a quarter of an 

 inch broad, fitting pretty clofe to the branches •, they 

 are entire^ and have a great number of fine iron- 

 coloured hairs on their edges and under fide. The 

 flowers are produced in bunches at the end of the 

 branches; they have one funnel-fl:iaped petal-, the 

 tube is about half an inch long ; the brim is cut into 

 five obtufe fegments, which Ipread half open; they 

 arc of a pale red colour, and have ten (lamina in 

 ^ach, which are the length of the tube ; after the 

 flowers are paft, the gerrnen in the center turns to an 

 oval capfule with five cells, filled with fmall feeds. It 

 flowers in May, and the feeds ripen in Auguft. ■ ' 

 The fecond fort grows naturally on the Alps and 

 Apennines ; this rifes with a flirubby fl:alk near three 

 feet high, fending out many irregular branches, co- 

 vered with a purplifli bark, and clofely garnifhed 

 with fmccth fpear-fhaped leaves an inch and a half 

 long, and half an inch broad in the middle ; they 

 are entire, and their borders are reflexed backward ; 

 the upper fide is of a light lucid green, and their 

 under fide of an iron colour j they are placed all 

 round the branches without any order. The flow- 

 ers are produced in round bunches at the end of the 

 branches ; they are funnel- fliaped, having fliort tubes, 

 which are cut into five obtufe fegments at the brim, 

 which fpread a little open ; they are of a pale Rofe 

 colour, and make a good appearance. . This fore 

 flowers in June, but does not ripen feeds here. ' ';' , 

 There are fome other fpecies of this genus which grow 

 naturally in the callern countries, and 'others are na- 

 tives of America, but the two forts here mentioned are 

 . all I have fcen in the Englifii gardens'; and thefeare 

 . ■ difficult to propagate and preferve'ih gardens, for they 

 erow naturally upon barren rocky foils and in cold fi- 

 .. tuations, where they are covered with Inow great part 

 ... of the winter; fo that when they are" pknte'd in better 

 - ■ ground, they do not thrive, and for want of their 

 •;; ufual covering of fnow in winter, they are frequently 

 killed by fl'oft ; biit could thefe plants be tamed, and 

 .- propagated in plenty, they would be great ornaments 

 .; to the gardens. ■ ■ / _ ■■.';/-:, 



..'They are propagated by feeds, but thefe are fo very 

 : fmall, that if they are covered deep, they will not 

 , groy^. The feeds fliould be fown as foon as poffible 

 *;. after tluy are ripe, either in fl:iady borders or pots 

 ■''■: filled with frefii gentle loamy earth, and "very light- 

 . ly covered with a little fine earth; then the pots 

 . ■ Ihould be plunged up to their rims in a (hady bor- 

 der, and in hard froil they fiiould be covered 'with 

 bell or liand-glafies, taking them off in mild 'wea- 

 ther. If thefe kcds are fown early in autumn, the 

 . plants will come up the following fpring; thefe mufl: 

 be kept fl:iadcd from the fun, efpecially the "firft 

 fummer, and duly refreflied with water, and in au- 

 tumn following, they may be tranfplanted to a fliady 

 fituation and on a loamy foil, covering the ground 

 about their roots with Mofs, which will guard th^m 

 froni froll in Vvintcr, 'and keep the 2:rGu:id n^cift in
