the plant is peculiar, it may be allowed a place in 
every colledtion of plants for the fake of variety, fince 
it requires no great trouble to cultivate it. 
Thefe plants may alfo be propagated by feeds, which 
fhould be fown on a warm border of light frefh earth, 
where fometimes they will remain a whole year be- 
fore the plants come up ; therefore when they do not 
come up the firft feafon, the borders fhould not be dis- 
turbed, but kept conftantly clear from weeds ; and the 
following fpring, wften the plants are come up about 
four inches high, they fhGuld be taken up and planted 
in pots, (and treated in the fame manner as hath been 
dire&ed for the cuttings ;) for if they are fuftered 
to grow in the border till they are large, they will 
not tranfplant fo well, nor will they make fo handibme 
plants. 
The third fort hath large fleftiy roots ; the branches 
are weak, and trail upon the ground ; thefe generally 
decay about Miafummer, and new fhoots are pro- 
duced late in autumn. The leaves of this come out 
in .bunches ; they are oval, plain, and not fo thick and 
fucculent as thofe of the other forts ; they are little 
more than an inch long, and half an inch broad. 
The flowers are produced from the wings of the leaves 
in February •, thefe are like thofe of the fecond fort, 
and have long (lender foot-ftalks. This never pro- 
duces any feeds in England ; however the cuttings 
will grow, if they are planted early in the fpring, fo 
that the fort may be propagated with the fame facility 
as either of the other kinds. 
All thefe forts require protection in winter ; but if 
they are placed in an airy glafs-cafe with Ficoides, and 
other hardy plants, whefe they may have a large fnare 
of free air in mild weather, and protedled from the 
froft, they will thrive much better than when they 
are more tenderly treated. 
TRTRAGONO THECA. Hort. Elth. 283. Lin. 
Gen. Plant. 875. Sun-flower, vulgo. 
The Characters are. 
The flower is compofed of hermaphrodite and female flo- 
rets , , which are included in one large common empalement , 
cut into four plain, triangular , heart-Jhaped fegments 
which fpread open . The diflk or middle of the flower is 
made up of hermaphrodite florets , which are f unnel -Jhaped, 
. and cut into five fegments at the brim, which are reflexed ■, 
they have five [sort hair-like flamina, terminated by cy- 
lindrical fummits, and a naked germen [upper ting a fender 
fltyle, crowned by two reflexed ftigmas. The germen af- 
terward becomes one naked roundijh feed. The female half 
florets which cornpofe the ray or border of the flower , have 
their petals ftr etched out like a tongue on one fide, and are 
cut at their points into three equal acute parts. Thefe 
have no flamina, blit a naked germen fupporting a fender 
ftyle with two twifled ftigmas', and are fucceeded by jingle 
naked feeds. 
This genus of plants is ranged in the fecond fedtion 
of Linnaeus’s nineteenth clafs, which includes the 
plants whofe flowers are compofed of hermaphrodite 
and female florets which are fruitful, and their fum- 
mits are connected. 
We have but one Species of this genus, viz. 
Tetragonotheca {Reliant Iodides.) Lin. Sp. Plant. 903. 
Tetragonotheca doronici maximi folio. Hort. Elth. 
378. Dwarf Sun flower, with a leaf like the greater 
Leopard's Bane. 
This plant is a native of Carolina, from whence the 
feeds were brought to Europe. The roots ,of this 
plant are perennial, but the ftalks are annual, and 
perifh in autumn on the approach of cold. The roots 
will abide through the winter in the full ground, if 
they are planted in a warm fituation-, fo do not require 
any fhelter, except in very fevere winters ; when, if 
they are covered over with rotten tan or Peas haulm, 
to keep out the froft, there will be no danger of their 
being killed. 
About the latter end of April or the beginning of 
May, the roots will fend forth new fhoots, which are 
garnifhed with large, oblong, rough leaves, placed by 
pairs, ciofely embracing the ftalks ; thefe are a little 
finuated on their edges, and are covered with fmall 
hairs. The ftalks ufually grow about two feet and a 
TEU 
half high in England, and branch Out toward the 
top into feveral fmalier ftalks, each having one large 
yellow flower at their top, fliaped like a Sun-flower ; 
which, before it expands, is covered with the inflated 
empalement, which is four-cornered. The feeds of 
this plant rarely ripen in England, but when they are 
obtained from abroad, they fhould be fown in the full 
ground in the fpring of the year ; where fometimes 
they will remain a year before the plants come up, fd 
that if they do not come up the fame year, the ground 
fhould not be difturbed, but kept clean from weeds, 
and v/ait till the fecond year to fee what plants will 
come up. When the plants appear they muft be 
kept clean from weeds, and if the feafon fhould prove 
dry, they will require to be frequently watered. In 
autumn the plants fnould be tranfplanted into the 
places where they are to remain. 
Thefe plants will live three years in a proper foil and 
fituation, but as it does not increafe here, the belt 
method is to procure good feeds from abroad an- 
nually. 
TETR APETALOUS FLOWER is one 
which is compofed of only four fmgle flower leaves, 
called petala. 
TEUCRIUM; Lin. Gen. Plant. 625. Tourn, 
Inft. R. H. 207. tab. 93. [takes its name from king 
Teucer, who was the firft amongft the ancients who 
brought this plant into ufe.] Tree Germander. 
The Characters are, 
The empalement of the flower is of one leaf, cut into 
five acute equal fegments at. the top , and is permanent . 
The flower is of the lip kind with one petal, having a 
jhort cylindrical tube a little incurved at the chaps. The 
upper lip is ere hi, and deeply cut into two acute fegments . 
The lower lip Jpreads and is cut into three fegments the 
middle one is large and roundijh, the two fide ones ark 
acute and ereht. It has four awl-Jhaped flamina which 
are longer than the upper lip , and are prominent between 
the fegments, terminated by fmall fummits. It has a 
germen divided in four parts, fupporting a fender ftyle , 
crowned by two fender ftigmas. The germen afterward 
turn to four roundijh naked feeds which . ripen in the 
empalement. 
This genus of plants is ranged in the firft fedtion of 
Linnaeus’s fourteenth clafs, which includes thofe 
plants whofe flowers have two long and two fhorter 
fcamina, and the feeds have no capfule.
