Thefe plants all grow naturally in the fouth of France, 
in Spain, and Portugal, from whence their feeds 
have been brought to England, where molt of the 
forts are now cultivated in the nurferies for fale. The 
firft fort hath a ftrong woody Item, covered with a 
rough bark, which rifes three or four feet high, di- 
viding into many branches, fo as to form a large 
bufhy head •, garnifhed with oval hairy leaves, placed 
oppoftte, and fit clofe to the branches, having feveral 
fmaller leaves of the fame form, rifing from the fame 
joint. The flowers are produced at the end of the 
branches, four or five ftanding together, almoft in 
form of an umbel, but rarely more than one is open 
at the fame time ; thefe are compofed of five large 
roundifh petals of a purple colour, which fpread open 
like a Role, having a great number of ftamina, fur- 
rounding- the oval germen in the center, terminated 
by fmall, roundifh, yellow fummits ; thefe flowers 
are but of fhort duration, generally falling off the 
fame day they expand ; but there is a fuccefiiori of 
frefh flowers every day for a conflderable time. After 
the flowers are paft, the germen fwells to an oval 
feed-veffel, fitting in the empalement, which is hairy j 
thefe capfules have ten cells, which are full of finall 
roundifh feeds. This fort flowers in May and June, 
and the feeds ripen in autumn; and there is generally 
more flowers produced in September and Odtober, if 
the autumn proves favourable, and where the plants 
are protected from froft, they frequently produce foffie 
flowers all the winter feafon. 
The fecond fort differs from the firft in the fhape of 
the leaves, which are longer and whiter ; thofe on 
the lower part of the branches are oval, and join at 
their bafe, furrounding the ftalks, .but the upper 
leaves are fpear-lhaped and diftincft ; the flowers are 
larger, and of a paler purple colour. This flowers 
• and ripens feeds at the fame time with the firft. 
The third fort differs from both the former, in having 
fhorter and greener leaves, which are joined at their 
bafe, and are hairy. The foot-ftalks of the flowers 
are much longer, and the flowers are fmaller, but of 
a deeper purple. This flowers and feeds at the fame 
time with the two former, and the fhrubs grow T as 
large as the firft fort. 
Th e fourth fort hath much larger and rounder leaves 
than either of the former, which are hairy, and 
fmooth on their upper fide, but rough, and full of 
veins on their under ; the branches are white, hairy, 
and the flowers are very large, and of a light purple 
colour. This flowers at the fame time with the 
former. 
The fifth fort doth not rife fo high as either of the 
former, but fends out branches near the root, which 
are hairy and ereft, garnifhed with fpear-fhaped 
leaves, of a dark green colour, which join at their 
bafe 5
