The Characters are. 
The flower hath a four-leaved empalement , which falls 
off. It hath four petals placed in form of a crofs. It 
hath fix ftamina , four of which are as long as the em- 
palement . , the other two are much floor ter and incurved ; 
thefe are terminated by roundiflo fwmmits. In the center 
is fituated a bifid germen , fupporting a permanent flyle , 
crowned by an oblong ftigma. The germen afterward be- 
comes a very floor t capfule with two cells , fleparated by the 
[welling flyle, which is oblique, and longer than the cap- 
fule . The valves are parallel to the middle , and divide 
the lower part of the cell from the upper , which is open , 
round , concave , and opens oblique , each cell containing a 
■ Jingle feed. 
This genus of plants is ranged in the firft fedion of 
Linnaeus;’ s fifteenth clafs, intitled Tetradynamia Siii- 
culofa, the flower having four long and two fhort fta- 
mina, and the feeds growing in fhort capfules or pods.

The firft fort grows naturally on the Alps, and other 
mountainous parts of Europe ; this is a very low 
plant, which divides into fmall heads like fome forts 
of Houfeleek, and from thence it was titled Sedum 
Alpinum &c. or Alpine Houfeleek. The leaves are 
fhort, narrow, and very hairy ; from each of thefe 
heads come out a naked fiower-ftalk an inch and a 
half high, terminated by loofe fpikes of yellow flow- 
ers, having four obtufe petals placed in form of a 
crofs ; when they fade they are fucceeded by trian- 
gular or heart-fhaped pods, which are compreffed, 
and inclofe three or four roundifti feeds. It flowers 
in March, and the feeds ripen the beginning of June. 
This plant is eafily propagated by parting of the 
heads ; the belt time for doing of this is in autumn, 
becaufe it ftioots up to flower very early in the fpring. 
It fhould have a moift foil and a fhady fituation, 
where it will thrive and flower annually. It requires 
no other culture but to keep it dean from weeds. 
The fecond fort is an annual plant, which grows na- 
turally upon walls and dry banks in many parts of 
England, fo is never cultivated in gardens. This 
flowers in April, and the feeds ripen in May. 
'% and othc* 
The third fort grows naturally on the Alp 
mountainous parts of Europe. This is a low peren- 
nial plant, which feldom riles more than two inches 
high *, it has a fhrubby ftalk, which divides into many 
fmall heads like the firft fort. The leaves are fmall, 
fome of them are winged, having five fhort narrow 
lobes, placed on a midrib, others have but three. 
The flowers come put in clufters, fitting clofe to the 
leaves. They are or a bright purple colour, and ap- 
pear early in the fpring. This is a perennial plant, 
which may be propagated by parting of the heads in 
the fame manner as the firft, and requires the fame 
treatment. 
The fourth fort grows naturally in fhady woods in 
many parts of Europe, and is but feldom kept in 
gardens, unlefs for the fake of variety. It is an annual 
plant, riling with an upright branching ftalk about 
ten inches high, garnifbed with heart-fhaped indented 
leaves, which embrace the {talks with their bafe. The 
{talks are terminated by loofe fpikes of white flowers, 
which appear the beginning of May; in June the 
feeds ripen, and the plants foon after decay. If the 
feeds are permitted to fcatter, the plants will come 
up without trouble. It muft have a fhady fituation, 
and delights in a moift foil. 
The fifth fort is an annual plant, which grows in 
fhady woods in the northern parts of Europe. This 
is like the former fort, but the leaves are larger, 
rounder, and do not embrace the ftalks ; they are 
alfo hairy, and the flowers are yellow. If the feeds of 
this are permitted to fcatter, the plants will maintain 
themfelves if they have a fhady fituation. 
The fixth fort riles with an upright ftalk about a 
foot high, the lower part being very clofely garnifhed 
by oblong hoary leaves, which are indented on their 
edges. The upper part of the ftalks puts out two or 
three fhort branches ; thefe are almoft naked of leaves, 
as is alfo the upper part of the ftalk. The flowers 
come out loofely on the top of the ftalk ; they are 
compofed of four fmall white petals placed in form 
of a crofs, which are fucceeded by oblong pods, which 
are twifted, containing three or four roundifti com- 
prefied feeds. It flowers in June, and the feeds ripen 
in July. This grows naturally in the north of Eng- 
land and in Wales. 
This plant feldom continues more than two years, 
but if the feeds are fown in autumn in a fhady border, 
the plants will come up in the fpring •, or where the 
feeds are permitted to fcatter, the plants will rife 
without any trouble.

The Characters are. 
The flower hath a floort permanent empalement of one leaf, 
which is tubulous. It hath one ringent petal , with a tube 
the length of the empalement , with large oblong inflated 
chaps. The upper lip is obtufe and arched , the under lip 
is trifid ; the two fide fegments are ere £1 , the middle turns 
downward and is indented. It hath four ftamina fituated 
near the upper lip , two being jhorter than the other, and 
are terminated by heart-fhaped fummits. It hath a four- 
parted germen, fupporting a Jlender flyle , fituated with the 
ftamina , and crowned by a bifid reflexed ftigma. The 
germen afterward becomes four oval oblong feeds, inclofcd 
in the empalement. 
This genus of plants is ranged in the firft feflion of 
Linnaeus’s fourteenth clafs, intitled Didynamia Gym- 
nofpermia, the flower having two long and two fhorter 
ftamina, and the feeds are naked.
