greatest difficulty. The leaves have an austere, astringent, bitterish taste, and are stimulant, narcotic, and 
diaphoretic. When taken, they first increase the arterial action and the heat of the body, producing 
diaphoresis; and these effects, according to Dr. Home's observations, are followed by a proportional diminution 
of excitement, the pulse in one case having been reduced thirty-eight beats. It has not been much used in 
this country. {Thomson's London Dispensatory, ¥11.) 
R. maximum grows on rocks and in barren soils, where it continues flowering great part of the year, and is 
very ornamental. 
R. ponticum grows in wet places in beech and alder coppices, on rocky mountains, but not on high alps. 
Rhododendrons are commonly propagated by layers, but some sorts produce seeds, and seeds of others are 
obtained from America. The seeds " should be sown early in spring, in flat pans or pots of peat soil, and very 
thinly covered : they may then be set in a close frame, or at the front of a hothouse, till they come up, water- 
ing them slightly when dry ; as soon as they are high enough to be laid hold of, they must be pricked out in 
other pots, which should be placed in a shady situation ; they may stand in a frame a few days till they have 
taken fresh root, but they must not remain long, or it will spoil them. The small kinds may be propagated 
freely by cuttings, taken off in the young wood, and planted in sand, under a bell-glass." {Bot. Cult. 815.) 
1015. Epig^ea. From tcri, upon, and y/j, the earth. The stem grows flat upon the ground, and throws out 
roots all the length of its branches. A very pretty little American plant with delicate white flowers. 
1016. Andromeda. Named in allusion to the virgin Andromeda, who, like this plant, was confined in a 
marsh, and surrounded by monsters of the waters. For an ingenious explanation of this application, see 
LinncBus's Flora Lapponica. The species are neat little plants, and some of them considerable shrubs and 
trees. They all require peat earth, and a moist situation ; for those of them which do not grow naturally in 
bogs are mostly inhabitants of alpine regions, where the air is always more moist than on plains. 
A. hypnoides has the appearance of a moss, spreads over great tracts of ground in the Lapland alps, and 
adorns them with its beautiful red flowers. The Andromeda is generally increased by layers, but may be also 
raised from seeds. " These must be very thinly covered, as thev are small, and would rot if covered deep :
