Ch. XXII] CLASSES AND ORDERS. 139 
586. ‘he genus Amygpatous contains the Peach and the Al- 
mond. The latter is a native of warm countries, and seems to 
have been known in the remotest times of antiquity. 
Orver Di-pentacynia, from two to five pistils. 
587. The four orders in the class Ic ssandria which follow the 
first, are included under one, calle? Di-pentagynia, signifying 
from two to five pistils. We find here the hawthorn, a shrub with 
deep green foliage, white flowers, and scarlet berries, and with 
very large and strong thorns. The genus Pyrus which contains 
the Apple and Pear, belongs here. The varteties of these 
fruits are the effect of cultivation, not the produce of different 
species. By means of grafting, which consists in inserting the 
sprout of one plant into the body or branches of another, good 
fruit may be produced upon a tree which before produced a 
poorer kind. ( 
Orver Potyeynia, many pistils. 
588. We here find the Rose; this, in its natural state, contains 
but five petals; it is remarkable for its stamens and pistils 
changing to petals by cultivation. Several species of the Rose 
sare indigenous to North America; as the small wild rose, the 
sweet briar, and swamp rose. ed and white roses are re- 
markable in English history as emblems of the houses of York 
and Lancaster; for when those families contended for the 
crown, in the reign of Henry the Sixth, the white rose distin- 
guished the partizans of the house of York, and the red those 
of Lancaster.—The Moss rose, Rosa muscosa, has its name 
from the moss-like substance with which the flower, stem, and 
calyx, are covered; it is in fact a collection of glands, contain- 
ing a resinous and fragrant fluid. Roses are favourite plants in 
all countries where they are found; but it is remarkable that 
none have ever been met with growing wild in the southern 
hemisphere.—Among the ancients, particularly the Egyptians, 
roses were considered as symbols of silence, for which reason 
the goddess Isis, and her son Harpocrates, who was the god of 
silence, were crowned with chaplets of those flowers. The 
eastern nations, especially the Persian, boast of the beauty and 
splendour of their roses. 
589. The Blackberry, (Rubus,) has a flower resembling the 
586. Of the genus Amygdalus? 
587. What is said of the order Di-pentagynia, and of some of the 
plants contained in it ? 
588. What is said of the Rose genus ? 
589. Of the different species of the Rubus ?
