Both thefe forts are very hardy, and may be eafily 
propagated by feeds, which Ihould be fown in au- 
tumn 5 for thofe fown in the fpring, often lie a 
year in the ground before they vegetate ; when the 
plants come up, they muft be kept clean from 
weeds, and thinned where they are too clofe. The 
following autumn they Ihould be tranfplanted where 
they are to remain, and the plants will flower in 
fummer, and produce feeds, but the roots will abide 
feme years.

It hath been a great difpute amongfl: modern wri- 
ters, whether the HyiTop now commonly known k 
the fame which is mentioned in fcripture •, about' 
which there is. great room to doubt, there being very 
little grounds to afcertain that plant, though it is 
raoft generally thought to be the Winter Savory, 
which plant is now in great requeft amongfl: the in- 
habitants of the eaftern countries, for outward walk- 
ings or purification.

The Characters are. 
The empalement of the flower is compofed of five round- 
iflo concave leaves , and is permanent. The flower has 
one bell-fhaped petal , which is bellied , cut into ten feg- 
ments. It hath five awl-jhaped ftamina arifing from the 
receptacle , terminated by halbert-fhaped fummit's , and an 
oval germen fupporting a ftyle the length of the ftamina , 
crowned by a headed ftigma. The germen afterward be- 
comes a roundijh berry with one cell , containing one feed. 
This genus of plants is ranged in the firft leflion of 
Linnaeus’s fifth clafs, intitled Pentandria Monogynia, 
the flowers having five ftamina and one ftyle.

The firft fort grows naturally in the ifland of Cuba, 
and in feme other warm parts of America ; it rifes 
with a Ihrubby ftalk about a foot high, which is 
ligneous at the bottom, and about the fize of a 
fwan’s quill, covered with a dark brown bark, lend- 
ing out a few (lender branches, garnifhed at inter- 
vals with hand-lhaped ftiff leaves, placed in whorls 
round them •, thefe are ftiff like thofe of Butcher’s 
Broom, ending with Iharp points, of a deep green 
on their upper fide, but pale on their under ; the 
flowers are (according to Plumier’s figure) produced 
from between the leaves on the top of the branches j 
but having feen no flowers in England, fo I can give 
no farther account of them. 
The fecond fort grows naturally at Carthagena, Mar- 
tinico, and other parts of South America, where it 
riles with a Ihrubby ftalk four or five feet high, di- 
viding toward the top into four branches, which are 
fituated in whorls round the principal ftalk, garnilhed 
with oblong blunt leaves, placed alfo in whorls, having 
a fhort flender apex. The flowers are produced in a 
racemus on the end of the branches, each .containing 
five or fix white flowers of a thick confidence, which 
J A S 
have a feent like Jafmine flowers, which they retain aftef 
they decay, fo are worn by the ladies of thofe countries 
for ornament. , 
The third fort grows naturally on the borders of the fea s 
in the ifland of Dominica ; this is an under-ffirub, of a 
very low growth, rarely riflng about two feet high, di- 
viding into feveral branches, garnilhed with linear ftiff 
leaves, ending with a thorn ; thefe are placed in whorls 
round the branches, and from the middle of the whorls 
come out the foot-ftalks of the flowers, each being ter- 
minated by one fmall white flower without feent. 
As thefe plants are natives of hot countries, fo they 
will not live in England, unlefs they are placed in a 
warm ftove, and treated in the manner directed for 
other plants from the fame countries, giving them 
little water in winter, and in warm weather plenty of 
frelh air. They are raifed from feeds, when they 
can be procured from the countries where they natu- 
turally grow ; which muft be fown on a hot-bed, 
and may afterward be propagated by cuttings* though 
it is with difficulty they take root.

The Characters are. 
The flower hath a tubulous empalement of one leaf, \ 
which is permanent , and cut into five fegments at the brim , 
which are erect. The flower is of one petals having a 
long, cylindrical tube , cut into five fegments at the top , 
which fpread open. It hath two fhort ftamina , which 
are terminated by fmall fummits , and are fituated within 
the tube of the petal. In the center is fituated a round- 
iflo germen , fupporting a fender ftyle , crowned by a bifid 
Jligma. The germen af terward turns to an oval berry ? with 
a ffltjkfn inclofimg two feeds , which are flat on thofe fitdes 
which join , a?id convex on the other.
