History, Use, Propagation, Culture, 
1012. Ledum. A-^hov was the name applied by the ancients to the plant producing the substance called 
Ladanum, and now known by the name of Cistus Ledum. In foliage the Ledum of modern botanists agrees 
with the plant of the ancients. Pretty American plants, very commonly cultivated for the beauty of their 
flowers. 
1013. Rhodora. A name of the same meaning as Rhododendron. It is weU known in shrubberies as remark- 
able for its purple flowers appearing on the naked shoots before the leaves come out. 
1014. Rhododendron. From poSov, a rose, and hiv^^ov, a tree, because the flowers resemble in color bunches 
of roses. Some of the species form beautiful and even splendid ornaments to the shrubbery or American 
ground ; and all of them are interesting and deserving of culture. 
Ft. ferrugineura and hirsutum abound on the high mountains of Switzerland, Austria, Savoy, Piedmont, 
Dauphine, and terminate ligneous vegetation as we ascend, and furnish the shepherds with their only fuel. 
The grouse are said to eat them ; and the white hares sometimes gnaw the bark in hard weather ; but animais 
do not seem to feed on them, except from want of other food ; and they are suspected of being in a small 
degree poisonous. The galls of some small insect are frequent on them. 
I{. dauricum is almost peculiar to the subalpine tracts of eastern Asia ; it appears first at the mouth of the 
river Jenisea, and beyond that, especially from the river Uda, in the pine woods, it begins to be common ; but 
about Baikal it is most abundant, and extends through the deserts of the Mongols to China and Tibet : at the 
Lena it becomes more rare, and beyond that it is much lower, with a more slender flower and narrower leaves. 
[Pallas.) 
R. Camtschaticum is an elegant evergreen under shrub ; it grows abundantly in the peninsula of Kamt- 
chatka and Behring's island in muddy places on the mountains. 
R. caucasicum is a native of the higher rocks of Caucasus, near the perpetual ice, in the highest range of 
shrubby vegetation, with Myrtillus and Vitis idsea. 
R. chry.santhum is a beautiful evergreen, resembling R. dauricum, and like it is a native of tlie aipine 
regions of Siberia, where it is a noted remedy for rheumatism. It is cultivated in this country with the
