Pàgina 318 - Brewster detected a beautiful arrangement of the silicious particles, which are distributed in two lines parallel to the axis of the stem, and extending over the whole surface.

Browne states that its stalk is employed to bring sugar to a good grain when it is too viscid, and cannot be made to granulate properly by the application of lime alone ; Arum ovatum is used for the same purpose.

Their timber, in commerce, is known under the names of Deal, Fir, Pine, and Cedar, and is principally the wood of the Spruce, the Larch, the Scotch Fir, the Weymouth Pine, and...
Pàgina 375 - The grains which extend farthest to the north in Europe are barley and oats. These, which in the milder climates are not used for bread, afford to the inhabitants of the northern parts of Norway and Sweden, of a part of Siberia and Scotland, their chief vegetable nourishment.
Pàgina 149 - Calyx 5-parted, toothed, or cleft, inferior, with the odd segment anterior ; the segments often unequal, and variously combined. Petals 5, or by abortion 4, 3, 2, 1, or none, inserted into the base of the calyx, either papilionaceous or regularly spreading ; the odd petal posterior.
