■ The fecond fort grows naturally in Jamaica, andfome 
of the other Hands in the Weft-Indies ; this is an an- 
nual plant, with pretty thick, compreffed, channel- 
ed ftalks which trail upon the ground, and are near 
two feet long, garnifhed with winged leaves placed 
by pairs oppofite ; thefe are fometimes compofed of 
three, but moil commonly of four pair of lobes, the 
outer being the largeft •, they are fmooth, and fit 
clofe to the foot -ft a! k. The flowers come out from 
the wings of the ftalk ; they are compofed of fivfe 
large yellow petals which fpread open, and have an 
agreeable odour ; thefe are fucceeded by roundifh 
prickly fruit ending in along point, but feldom ripen 
in England. 
The third fort grows naturally in the Weft-Indies •, 
it was found by the late Dr. Houftoun at the Havan- 
nah i this has a ligneous root, from which fpring out 
many ftalks which are hairy, jointed, and trail upon 
the grouftd ; thefe are garniftied at each joint by 
winged leaves, which differ greatly in fize, one of 
the leaves at each joint being compofed of eight pair 
of oblong lobes which are nearly equal, and oppo- 
fite to this comes out a fmall leaf compofed of but 
four pair of lobes. The large leaves ftand alternate- 
ly upon the ftalks, and the fmall ones on the oppo- 
fite fide ; the ftalks are near two feet long, and at the 
wings of the ftalks come out the foot-ftalks of the 
fibwers, which are hairy, and near two inches long, 
,^ach fuftaining one pale yellow flower, compofed of 
five large petals, which have narrow tails, but are 
very broad and rounded at their points. The flowers 
are fucceeded by roundifh fruit armed with very acute 
fpines, but thefe rarely ripen in England. 
The two laft forts being natives of hot countries, 
are very tender, fo muft be fown on a hot-bed early 
in the fpring; and when the plants are come up, they 
muft be each tranfplanted into a feparate pot filled 
with rich light earth, and then plunged into a hot-bed 
of tanners bark, where they muft be treated in the 
fame manner as other tender exotic plants, being care- 
ful to bring them forward as early as poflible in the 
fummer, othenvife they will not perfect their feeds in 
this country. 
The third fort will live through the winter, if it is 
plunged in the bark-ftove, and treated in the fame 
way as other tender plants, and the following fummer 
they will flower earlier, fo there will be more time for 
the feeds to ripen. 
TRICOMANES, Maiden-hair. 
There are three or four varieties of this plant, which 
o-row naturally in Europe, but in America there is 
a great number of fpeeies, which are remarkably 
different from each other, as alfo from the European 
kinds. 
Thefe being of the tribe of Ferns or capillary plants, 
are feldom preferred in gardens. Their roots fhould 
be planted in moift fhady places, efpecially the Euro- 
pean forts, which commonly grow from between the 
joints of old walls, and in other very moift'fhady fitu- 
ations-, but thole forts which are brought from hot 
countries, muft be planted in pots filled with rubbifh, 
and ftrong earth mixed, and in winter they muft be 
fcreened from hard frofts, to which, if they are expof- 
ed, it will deftroy them. 
The comqnon fort in England is generally fold in the 
markets for the true Maiden-hair, which is a very 
different plant, and not to be found in England, it 
being a native of the fouth of France, and other warm 
countries, fo is rarely brought to England.

The Characters are. 
It has male and female flowers at feparate difiances on the 
fame plant. The male flowers have a long fmooth empale- 
ment of one leaf , cut into five fmall fegments at ihe top , 
which are reflexed the petal is plain , fpr ending , and cut 
into five parts , ending in long branching hairs ; they have 
three Jhort flamina arifing from the point of the empale- 
ment , terminated by cylindrical erebi flummits joined in a 
, body, and three fmall flyles faflened to the empalement.

Tfa female flowers fit upon the germen , and have empale- 
ment s and petals like the male flowers, but have no 1 fta- 
mina \ they have a long fiender germen fituated under the 
flower, fupporting a ftyle tie length of the empalement , 
crowned by three oblong fligmas. The germen afterward 
turns to a fucculent fruit having three cells , inclofin ? ma- 
ny compreffed feeds. 
This genus of plants is ranged in the tenth feftlon 
of Linnaeus’s twenty-firft clafs, which includes the 
plants whofe flowers have male and female florets 
on the fame plant, and the fummits are connected 
together. 
We have but one Species of this genus in the Eng- 
lifh gardens, viz. 
Tricosanthes (. Anguina ) pornis teretibus oblongis in- 
ctirvis. Hort. Cliff. 450. T ricofanthes with a taper, ob- 
long, incurved fruit. Anguina Sinenfis, flore alboele- 
gantiflimo, frudtu oblongo intorto. Michel. Gen, 12. 
tab. 9. China Serpent Cucumber with a moft elegant white 
flower, and an oblong intorted fruit. 
This plant grows naturally in China, it is an annual, 
and of the Cucumber tribe. The ftalks run to a great 
. length, and if they are not fupported, trail upon the 
ground, in the fame manner as Cucumbers and Melons. 
The leaves are angular and rough •, the flowers come 
out from the fide of the ftalks ; they are white, and 
cut into many fmall filaments or threads. The fruit 
is taper, near a foot long, incurved, and divided into 
three cells, which include many compreffed feeds like 
thofe of Cucumber. 
It is propagated by feeds, which muft be fown on a 
hot-bed early in the fpring, and afterwards treated in 
the fame Way as Cucumbers and Melons, keeping 
them covered with glades, othenvife they will not 
ripen their fruit here. 
TRICHOSTEMA. Gron. Fior. Virg. 64. Lin. 
Gen. Plant. 652. , 
The Characters are, 
It has a lipped empalement to' the flower of one leaf the 
upper lip is twice as large as the under, and is cut into three 
equal acute fegments , the under lip into two. The flower 
is of the lip kind, it has a very Jhort tube ; the upper lip 
is compreffed and hooked, and the under lip is cut into three 
fegments , the middle one being the leaf ; it has four hair- 
like flamina which are long and incurved , two of them be- 
ing a little fhorter than the other , terminated by Jingle fum- 
mits, and a four -pointed germen fupporting a long fender 
ftyle , crowned by a bifid Jiigma. The germen afterward 
turn to four roundifh feeds, inclofed in the fwollen empale- 
ment of the flower. 
This genus of plants is ranged in the firft feftion of 
Linnaeus’s fourteenth clafs, which includes thole plants 
whofe flowers have two longer and two fhorter ftami- 
na, and the feeds are naked in the flower-cup. 
The Species are, 
1. Trichostema ( [Dichotomum ) ftaminibus longiffimis 
exfertis. Lin. Sp. Plant. 598. Trichoftema with the 
longeft ftr etched out flamina. Caflida Mariana, majora- 
nae folio. Pet. Sue. 243. Maryland Scull Cap with a 
Marjoram leaf. 
2. Trichostema {Brachiatum ) ftaminibus brevibus in- 
clufis. Lin. Sp. Plant. 59S. Trichoftema with floorter 
flamina included in the petal. Teucrium Virgin ianum 
origani folio. Hort. Ekh. 380. Virginia Germander with 
a wild Marjoram leaf. 
The firft fort grows naturally in many parts of North 
America ; it is an annual plant, which rifes about fix 
or eight inches high, dividing into fmall branches, 
which are garnifhed with fmall roundifh leaves, not 
unlike thofe of Sweet Marjoram ; thefe are placed 
oppofite, and are covered with fine, fmall, downy 
hairs. The flowers are produced at the wings of the 
branches ; they are fmall, and of a purple colour, 
gaping with two lips ; the upper lip is arched, and 
is much larger than the lower •, it is cut into three 
acute points •, the lower lip is fmall, and cut into two 
points. Thefe appear late in Auguft, fo that unlefs 
the feafon proves warm, the feeds will not ripen in 
England.
