Now to those who know anything of the important contributions of Grimm, Rhŷs, Frazer, and many others we might name, to our knowledge of the mythology, worships, and customs in the Mediterranean basin and western Europe, an inspection of the first columns in the above tables will show that here we have a common meeting-ground for temple orientation, vegetation and customs depending on it, religious festivals, and mythology. From the Egyptian times at least to our own a generic sun-god has been specifically commemorated in each of the named months. Generic customs with specific differences are as easily traced in the same months; while generic vegetation with specific representatives proper to the season of the year has been so carefully regarded that even December, though without May flowers or August harvests, not to be outdone, brings forward its offering in the shape of the berries of the mistletoe and holly. About the mistletoe there is this difficulty. Innumerable traditions associate it with worship and the oak tree. Undoubtedly the year in question was the solstitial year, so that so far as this goes the association is justified. But as a rule the mistletoe does not grow on oaks. This point has been frequently inquired into, especially by Dr. Henry Ball (_Journal of Botany_, vol. ii. p. 361, 1864) in relation to the growth of the plant in Herefordshire, and by a writer in the _Quarterly Review_ (vol. cxiv.), who spoke of the mistletoe “deserting the oak” in modern times and stated, “it is now so rarely found on that tree as to have led to the suggestion that we must look for the mistletoe of the Druids, not in the _Viscum album_ of our own trees and orchards, but in the _Loranthus Europaeus_ which is frequently found on oaks in the south of Europe.” On this point I consulted two eminent botanical friends, Mr. Murray, of the British Museum, and Prof. Farmer, from whom I have learned that the distribution of _V. album_ is in Europe universal except north of Norway and north of Russia; in India in the temperate Himalayas from Kashmir to Nepaul, altitude 3000 to 7000 feet. The _Viscum aureum_, otherwise called _Loranthus Europaeus_, is a near relation of the familiar mistletoe, and in Italy grows on the oak almost exclusively. There are fifty species of Loranthus in the Indian flora, but _L. Europaeus_ does not occur.
