ANALYSIS OF 
the number of Stamens. 75, Seed-velTd of Draba (Whitlow 
Grafs) a Silicle. Seed-veffel cf Hefperis (Purple Rocket) a 
Silique. Many Plants of the clafs Tetradynamia, Four- 
powers, eaten, fome without cookery 5 variety of eatable 
plants from the genus Braffica. Change produced in plants 
by the art of gardening an amufing part of the ftudy of 
Botany. Specimens of the clafs Moriadelphia, One brother- 
hood. Stamens firmly united at the bafe. 76, Syftematic 
character of the clafs Diadelphia, Two-brotherhoods, mown 
in Pea. 77, Curious circumftance refpe&ing the Piftil of 
Common Broom. J&, Specimen of the clafs Polyadelphia 
(Many brotherhoods). Stamens of Hypericum (St John's 
"Wort) beautiful j the only Britifh genus of the Polyadelphia 
clafs. The genus Citrus, comprifes Orange, Lemon, and 
Citron. Different appearance of their Stamens to thofe of Hy- 
pericum. 84, Explanation of the clafs Syngenefia, or United 
Anthers. Elafticity of the Filaments in the Flowers of 
this clafs j 7Q, confifts of the Compound Flowers; natural, 
if a few Genera be excepted ; this exception a fault in the 
fyflem. What conftitutes a Compound Flower. 80> Generic 
character founded, in part, on the variety in the form of the 
Corol. The firft four Orders founded on the Stamen-bearing 
and Piftil bearing Florets. Mark of the Fifth Order. Sixth 
marked by the Corols being fimple. 81, Perhaps, from this 
circumftance, ought to have been feparated from the Clafs. 
Placed in it by their Anthers being united. Linneus does not 
pretend to make his ClafTes natural. Gratitude due to Linneus 
from all Botanifts due alfo to his predecetfors. Tournefort's 
fyftem ingenious. Orders of the clafs United Anthers cannot 
be retained by the memory without examining flowers belong- 
ing to each. 82, Scabious has the appearance of a Compound 
Flower; belongs to the clafs Tetrandria, Four- fta mens. 
Marked diftinctions between them. 83, Scabious, a fpecimen 
of an Aggregate Flower. Specimens of the orders of the clafs 
United Anthers mould be fiudred according to their orders. 
Florets of the Fourth Order having Stamens and Piftils not the 
only
