LoMut-a ramnm. 
Befide thffe, there are no lefs than fifteen other 
En'Mifh fpecies of pondivee^d ; the general form of 
which being the fame» we fliall avoid the repeti- 
tion of fo many defcriptions, and give their names 
and characters. 
1. Long, pclIucid-lcaved Great Pondweed, Po- 
tiimogiion foUis angujlis fplendentibus. Diftin- 
guifhed by the length of the leaf. 
z. Grafly Pondweed, Potamogiton folio angujlo 
pellucido fere gramhieo. Smaller than the

11. Fennel-leaved Pondweed, Potamogiton milU-

12. Dwarf Grafly Pondweed, Potamogiton pufil-

13. Broad, thin-leaved Pondweed, Potamogiton

15. Dwarf feathered Pondweed, Potamogiton pen- 
7iatum minus. Smaller, and more branched

From this detail of tlieir difi^crences, the flu- 
dent will much more readily comprehend the fe- 
veral fpecics than if they had been feparated un- 
der fo many difiinft heads, and enciimbered with 
repetitions ; for the flowers are of the fame form 
and colour in all, and the general manner of 
growth in nothing different.

ORACH. 
A T R I P L E X. 
TFIE flowers are of two kinds, hermaphrodite and female, on the fame plant. The hermaphro- 
dite flower confifls of a cup, formed of five membranaceous leaves, with filmy edges, and en- 
cioHng afterwards a fingle feed. The female flower confilts of a cup, formed only of two leaves ; 
which are of an ovai form, large, and comprefied. Thefe afterwards ferve to defend alio a fingle 
ftcd. 
Linn:Eus places this among the polygamin mouxcia; the feeds being ripened in two ways on the 
fame plant, from hermaphrodite and female flowers.

Befide this, there are no lefs than thirteen other 
fpecies of ivild orach, common on our dunghills \ 
and fome others of the blite kind, which are alfo 
called by the name orach^ the difl:inction not 
having been obvious to the earlier writers. We 
fhall explain that under th e next genus ; and fiiall 
here, as in the preceding article, enumerate the 
fpecies, with their eflential and diftin^flive parts ; 
the general afped being in common. This, which 
we begin in recounting thclefs confpicuous and lefs 
N^XLIX. 
ufeful plants, mufl be continued when we give the 
reader an idea of the grafies, mofies, and muih- 
rooms i articles which have fingly furnifhed the 
fubjeifl of volumes in folio; blit which we fhall 
compriie in a fufncient view in the few remain- 
ing numbers of this work.
