and Miscellaneous Particulars. 
P. orientale is a well known annual, showy, and fit for shrubberies. The seeds were first sent to Europe by 
Tournefort, who saw it growing in the garden of the monks of the three churches near Mount Ararat. They 
cultivate this plant there, not only for the beauty of the flowers, but for its medicinal qualities, which are the 
same with those attributed to our common species. {Mill. Fig.) The seeds are farinaceous. 
P. aviculare is so named from the gratefulness of its seeds to small birds ; the English name, knot-grass, 
from the knottiness of the stem, and because it is eaten by cattle ; many such plants having obtained the name 
of grass, though they bear no similitude to real grasses. Hogs eat it with great avidity, and hence it is known 
in many countries by the name of hogweed. All other domestic quadrupeds are said to eat it. The seeds are 
useflil for every purpose in which those of buckwheat are employed, but they are much smaller. 
P. Fagcpyrum, {Fagus, beech, and m^o;, corn, its grain is like the mast of beech,) properly beechwheat. Bled 
noir or Sarrazin, Fr. Buckwheat is considered a native of Asia and not of Europe, though sometimes found 
in a seemingly wild state. It will not, however, bear the frosts of our springs or the severity of winter. In 
China and other countries of the East, it is cultivated as a bread corn. The flower is also used in cookery and 
bread-making in various parts of Europe, to make cakes and crumpets in England, and as rice or gruel in 
Germany and Poland. The seed is said to be excellent for horses and poultry, the flowers for bees, and the 
plant green for soiling cows, cattle, sheep or swine. As an agricultural plant it is valuable, as standing only a 
short time on the ground ; but it produces little straw for manure.

tree in most of the sugar colonies, generally near the sea. It is remarkable for its large leaves, and when of
