This genus of plants is ranged by Dr. Linnaeus in 

 the fecund feclion of his ninteenth clafs ^ the flowers 

 of this feftion are compofed of hermaphrodite florets 

 in tlie center, and female in the circumference. 

 The SpiiCiEs are, 



1. Amellus (Lychnitis) foliis oppofitis lanceolatis obtu- 

 fis, pedunculis unifloris. Lin. Sp. 1276. Star-flower, 

 with fpear-fhaped obtufe leaves placed oppofite^ and one 

 flower on each footftalk,

 tus tomentofis, floribus umbellatus. Amcen. Acad. 

 5. p. 407. Star-flower with oppofite leaves having three 

 veinsj and flowers in umbels. 



The firft fort grows naturally at the Cape of Good 

 Hope. It rifes from two to three feet high, fending 

 out branches on every fide, garnilhed with fpear^ 

 lliaped leaves placed oppofite, terminated by flower- 

 ftalks, each fupporting one Violet-coloured flower, 

 with a yellow diflc, Ihaped like thofe of the Afl:er, 

 which appear in July or Auguft. 

 This is a perennial plant, which is eafily propagated 

 by cuttings, which, if planted in (hade during any 

 of the fummer months, and duly watered, will put 

 out roots ; thefe fiiould be taken up with balls of 

 earth to their roots, and planted in pots, that they 

 may be ftieltered in winter, either under a common 

 frame, or in a green-houfe, where they may have 

 plenty of air in mild weather, otherwife they will

from whence the feeds were fcnt to the imp -r-il o-a-' 

 den at Peterlburgh, where the plants flou-invd'^and 

 perfeded their feeds, part of whicli were fcnt me by 

 the late Dr. Amman, which grew in the ChelJea 

 den, where the plants annually produce feeds. 

 Itis an annual plant with an upright ftalk,' wliich 

 riles about a toot high ; toward the top it puts out 

 two or three fmall lateral branches, garniibed with 

 Imall tnfid leaves, fa wed on their edges, of a very 

 dark green colour ; at the extremity of the branches 

 the flowers are produced in fmall umbels ; they are 

 of a fine blue colour, as are alfo the upper part 

 of the branches, and the leaves immediately under the 

 umbel ; fo that although the flowers are fmall, yet 

 from their colour with thofe of the upper part of the 

 italics, the plants make a pretty appearance, during 

 their continuance in flower. If the feeds of this plant 

 are fown in the autumn, or are permitted to fcatter, 

 the plants will come up early the following fprino-' 



J 



thofe which are fown in the fpririg, will not flower till 

 July ; and in dry feafons, the feeds will remain in the 

 ground a whole year, fo that the befl: time for fow- 

 in.g them is in the autumn. 



When the plants come up, they will require no other 

 care but to keep them clean from weeds, and where 

 they are too clofe to thin them ; for they do not tiirive 

 when tranfplanted, therefore the feeds fliould be fown 

 where they are to remain.

This genus of plants is by Dr. Linnaeus ranged in 



his fecond clafs of plants, entitled Diandria Mono-

The firft fort grows naturally in moift places in Jamai- 

 ca, from whence Dr. Houfton fent the feeds to Eng- 

 land, wliich fucceeded at Chelfea, and have from- 

 thence been diftributed to moft of the botanic gar- 

 dens in Europe. 



It grows about a foot and a half high, with an upright 

 fquare ftalk, and long narrow leaves {^t in form of a tri- 

 angle, whofe bafe half furrounds xt ; thefe grow the 

 whole length of the ftem. They are of a pale, green, 

 and of the confiftence of thofe of Purflane ; the ftalks 

 are alfo fucculent, and of the fame colour with thofe 

 of that plant. The flowers come out in whorles round 

 the ftalks, at the joints where the leaves adhere, in 

 clufters : thefe have no petals, fo make no great ap- 

 pearance, and are foon fucceeded by round feed-vef- 

 fels, which are full of fmall feeds. ^ 

 The plant muft be raifed on a hot-bed in the fpring, 

 and afterward itmoved to another hot-bed to bring 

 it forward. When the plants have acquired ftrength, 

 they fliould be tranfplanted into pots filled with rich
