V. Urtica minor iners fpicata, folio fubrotundo ferrato, fructa tricocco. 
Cao. 38 Tab. 07 Figg, 
This has a Root five Inches long, big in proportion to the Plant, brown 
on the outfide, and deeply fix’d in the Earth, which fends out on every 
hand feveral {mall Stems, lying along the Surface of the ground, two Inches 
in length, having {mall Leaves plac’d, without any order, on the Branches. 
Each leaf hath an eighth part of an Inch long Foot-Stalk, is one third 
part of an Inch long, and very near as broad at Bafe, where broadeft: al- 
moft round, {mooth, and fnipt about the edges. The top of the Stem isa 
Spike of Flowers an Inch long, made up of a great many very {mall 
Purple Flowers, fome little white intermingled. After thefe follow, in 
the fame Spike, feveral tricoccous Heads, at firft green, and then a little 
reddifh, and rough on the ourfide. In each of thefe lie three roundifh 
Seeds, every one is covered with a Membrane, and the three Membranes 
being joined, make upa tricoccous Seed, like that of the Aeliotropinm tri- 
coccum, only infinitely {maller. 
It grows in the Town Savanna, every where in the fandy places thereof, 
efpecially towards two Mile Wood. 
This cannot be the Plant mentioned by Dr. Plukenet: Mant. p.190. 
VI. Urtica major racemofa humilior, pungens fed non urens. Cat. p. 38. 
This hada woody, reddifh Root, about. five Inches long, having feveral 
lateral Fibrils, by which it drew its Nourifhment from the Earth. The Staik 
was round, woody, green, and about a foot high, having near its top feveral 
Leaves, without any order, ftanding on Inch long Foot-Stalks. They were 
five Inches long, one broad, inthe middle, where broadeft, very much fer- 
rated, and rough like Nettle Leaves, of a dark green colour, the back fide of 
the Leaf being lighter ; thefe Leaves were very rough and pricking. In thé 
Plant I examined, I cou!d not obferve any veficles at bottom of the prickles 
as in Nettles; but the pricking of rhe Finger came from fome very hard 
and white prickles was vifible on the Leaf by the Microfcope. By the 
Foot-Stalk, at the beginning of the Leaf, is a very ihort fuftaining four 
{mall membranaceous Leaves or Petala, within which are five or fix 
yellow Stamina, to which follows a roundifh Cap/wla, made up of three 
pieces which open of themfelves, throwing out feveral fmall oblong brown 
Seeds. : 
It grew on the Banks of the Rio Cobre, above the Town of St. Faco de la 
Vega, on the other fide of that River. 
’Tis plain by this defcription that this cannot be the Urtica racemofa Cana- 
denfis Morif. as Dr. Plukenet thinks in his Mantiff.p. 190. neither can it be the 
third defcribed in this Chapter, as he there imagines.

This rofe to about three Foot high, by a ftrong, ftriated, woody, folid 
Stem, as big as ones little Finger, having at pretty large diftances, Leaves, 
which ftand on an Inch and a half long Foot-Stalks. They are cut and di- 
vided juft after the manner of the Leaves of Mugwort, to which they are 
very like, only fomewhat larger and ftronger, being rough, but not hairy 
like the ambrofia marina, C.B. pin. and of avery dark green colour above, 
underneath more pale. Fx alis fol. and towards the top come Twigs, 
having {maller Leaves, and on their gs a great many {mall mufcofe 
k Flowers,
