ON THE MEANING OF THE NAME WALNUT. Mr. G. B. Airy lately advanced the opinion (Athenaeum,' 1865, p. 653) that the national name “ Welsh ” might possibly be a corruption of the word “Belgæ.” This opinion I endeavoured to controvert (ibid. pp. 690, 728, 774) by showing that the term Welsh, identical with the German Welsch, Wälsch, or Kauderwelsch, was and is applied by Teutonic nations to foreigners and foreign things in general. “The Saxons conquering this island,” says Sir John Dodridge, in 1620, “called the said territorie [Cambria] Wallia, and the people Welshmen, that is to say unto them strangers.” The modern Germans call Italy “ Wälschland," and the Italians “ Wälsch." There is only one other English word in which the original meaning of the word has been preserved, i.e. “Walnut,” which in German is “ Wälsche Nuss” (=“ Welsh Nut”), as the turkey-cock is “ Wälscher Hahn" (=Welsh cock). Both the Walnut and the turkey being indigenous to the Indies, the former to the East and the other to the West, it shows that the Germans do not use the term “ Welsh " in the restricted sense of Italian, as has been maintained. The Walnut was cultivated in Italy in Pliny's time, and if it had come to us direct from that source instead of the Trans-Caucasian countries, we should probably have for it a corrupted Latin name, as we have for nearly all those of our fruit-trees (Cherry, Plum, Pear, etc.) for the introduction of which we are indebted to the Romans.

BERTHOLD SEEMANN.

PHYLLOMANIA. Are there any people who entertain a real affection for flowers ? If so, then how does it come to pass that flowers at one time the greatest favourites are, after a few years of popularity, no longer looked at,-in common parlance, gone out of fashion ? Our great nurserymen are the first to find out in which direction the taste is tending; as soon as a plant ceases to be inquired for, they get rid of it at any price, to fill its place with the few favourites of the public; and the effect is, that plants which were seen in every garden, though their price was high, become extremely scarce, and finally disappear altogether. Fashion, in this as in other things, is never without a reason for adopting an innovation. The Cactuses, of which, at one time, ship-loads came to our shores, were discarded because they were such spiny, irritating things, and which, in public gardens, you were requested not to touch. The Aloes, now only seen in all their diversified forms in Prince Salm-Dyck's magnificent works, had to make room for less interesting types, because you had to wait for a series of years before many of them flowered ; popular opinion declared it was sometimes a whole century. Such plants might be in their place in antediluvian times, when people as old as Methuselah were plentiful, but scarce fit garden-pets when human life seldom reaches fourscore years. Then came the reign of the Dahlias, a brilliant and prosperous one, but suddenly cut short by the startling discovery that they flowered late in the autumn, and were apt to be killed by the first night-frost. Last autumn, when enjoying the fine show of Chrysanthemums in the Temple Gardens, we trembled at the very thought that somebody who has a voice in the fashion of flowers should find some argument why this lovely sight should not be seen ; why the Chrysanthemum, with its marvellous variety of colour, much more the “ Pride of London ” than the little humble Saxifrage of that name, should be banished for some new, untried favourite, perhaps not half so well adapted to the smoky atmosphere of our capital.

As long as one set of flowers is superseded by another, there is, perhaps, not much to complain of; but a fashion is gradually creeping in, well calculated to create alarm. Endeavours are now being made to persuade us that it is but a depraved taste to admire flowers at all; that it is the foliage on which nature has lavished the greatest beauty, and that here real taste has proper objects for gratification. The Ferns were the first of this class of plants which gained a footing amongst us.

The elegant and graceful tracery of their foliage was so bewitching that a perfect rage for them sprang up, and during the last ten years more books have been written about them than since botany became a science. The species indigenous to our islands have been illustrated in every imaginable manner; in bulky volumes, as in “The British Ferns Nature-printed,' and in portable companions, as in “ The British Ferns at One View. There is hardly a publishing house that has not
