extremity, and are ot a dark green colour. The 

 flower-Hem rifes about twelve feet high, and branches 

 out toward the top in the fame manner as the third 

 fort ; the flowers are nearly of the fame flze arid co- 

 lour as thofe of the third, and after they fall off^, are 

 fucceeded by young plants in the fame manner. A 

 plant of this kind flowered in the garden at Chelfea, 

 in December 1 754. This never produces any fuckers 

 from the root, fo cannot be increafed until it flowers. 

 l^he leaves of the fixth fort are from two feet and a 

 half to three feet long, and about three inches broad, 

 being of a dark green colour, ending in a black fpine ; 

 the borders of the knaves are of a brownifli red colour, 

 and nightly ferratcd. Thefe fliand m.ore ereft than in 

 the other fpecles ; but as this fort hath not flowered 

 in England, fo I cannot fay how it difi^ers from the 

 other. The plants of it were fent me from St. Chrif- 

 topher's, by the title of Koratto, which I fuppofe is 

 given indifferently to odier fpecies of this genus ; for 

 I have frequently heard the inhabitants of America 

 call the common great Aloe by the fame name. 

 The eighth fort hath long, narrow, fl:ifi^ leaves, which 

 are entire, and are terminated by a ftift^ black fpine. 

 Thefe leaves are feldom more than two feet lono-, and 

 little more than an inch broad, being of a glaucous 

 colour. The fide leaves fliand almoft horizontally, 

 but the center leaves arc folded over each other, and 

 inclofe the flower-bud. This fort never puts out 

 fuckers from the root, nor have I (t:en any* plants of 

 this kind in flower, although there are many of tliem 

 in the Englifli gardens, fome of which are of a con- 

 fiderable 



\ 



ap*e. 



The third, fourth, fifth, fixth, and eighth forts, are 

 much tenderer than the others, fo cannot be preferved 

 througli the winter in England, unlefs they are placed 

 in a vvarm flove ; nor will they thrive if fet abroad in 

 fummer, therefore they ftiould confl:antly remain in 

 the fl:ove, obferving to let them enjoy a great fliare of 

 free^air in^warm weather. They require alight fandy 

 earth, and fliould have little wet in winter; but in 

 warm weather, may be gently watered twice a week,

all the branches are clofely befet with them, 

 v/as a plant of this kind which flowered in the Chelfea 

 garden 1755, the fl:cm of which begun to flioot the 

 beginning of October, and by the end of that month 

 was upwards often feet high, by the end of Novem- 

 ber it was near twenty, and the lower lateral brandies 

 v/ere upward of four feet long, the others decreafinj^ 

 gradually, fo as to form a regular })yramid. In De- 

 cember the ftalks were clofely garniflied widi flowers, 

 and in the Ipring, wlicn the flowers dropped olf, they 

 were fucceeded by young plants, which as they fell 

 ofi^' and dropped into the pots which flood near, put 

 out rjots and become good plants. This fort never 

 produces ofi^'sets from the root, fo that it cannot be in- 

 creafed but wheA it flowers, at which time there will 

 be plenty enough. The old plant prefently after 

 dies. 



The fourth fort hath leaves fomev/hat like the third 

 in fliape and colour, but they are indented on their 

 edges, and each indenture terminates in a fpine-, the 

 root of tliis fort is thick, and fwells jufl: above the fur- 

 face of the ground, in other refpects it agrees with 

 the fonmer. This fort hath not flowered in Eno-hnd,

therefore I cannot tell how it differs in its flov/ers from 

 the other. I have raifed this from feeds which v/ere 

 fent me from America, but the plants never put out 

 fuckei's from the roots, fo that it can only be propa- 

 gated by feeds. Dr. Linn^us fuppofes it to be the 

 fame with the third fpecies, but v/hoever fees the plants 

 will not doubt of their being difl^erent. 

 The fifth fort never grows to a large fize i the leaves 

 of it are feldom more than a foot and a half long, and 

 about two inches and a half broad at their bafe ; thefe 

 end in aflender fpine, being flightly indented on their 

 edges ; they are alfo reflexed backward toward their 3 



and are of a dark green colour.

 be ftiifted every llimmer into frefli earth, but mull 

 not be put into lai-ge pots; for unlefs their roots are 

 confined, the plants will not thrive.

The two firft are annual plants. The feeds of thefe 

 muft be fown on a hot-bed in the fpring, and when 

 the plants are come up and are flrong enough to re- 

 move, they fliould be tranfplanted into another mo- 

 derate hot-bed, obferving to water and fiiade them 

 until they have taken root, after wliich time they muft 

 have a good fhare of air in warm weather. In June 

 they fliould be" inured to bear the open air, toward 

 the middle of which montli, they may be tranfplanted 

 into the full ground, where they will begin to flower 

 in July, and continue flowering till the frofts in au- 

 tumn defl:roy them. The feeds ripen in September 

 and 06lober, and when any of them fcatter upon the 

 ground^ and the fame earth happens to be put oh a 

 hot^bed the following fpring, the plants will come up 

 in great plenty, as they frequently do in the open air ; 

 but tliefe plants will be too late to produce good feeds, 

 unlefs the fummer proves warm. The firft; fort grows 

 naturally in Africa, and alfo in the iflands of Ameri- 

 ca J for in tubs of earth which I received with plants 

 from J ' " ' ' 



plenty of the plants arife, from feeds which were fcat- 



The fecond fort was found 

 growing naturally at La Vera Cruz, by the late Dr. 

 William Houflroun, who fent the feeds to Europe, 

 which have fo well fucceeded in many gardens, as to 

 become a weed in the hot-beis,' There is a variety 

 : of this with white flowers, which arifes from the fame 

 feeds. 



The diird fort grows naturally in North America, but 

 has been many years an inhabitant of the Enghfli gar- 

 dens. This hath a perennial root and an annual fl;alk ; 

 theftalks will grow five or fix feet liigh, and toward dieir 

 tops put out fide branches : the leaves arc fhaped like 

 ^ a heart. At the ends of tlie fiioots the flowers are pro- 

 duced In large tufts, which are of a pure white j and
