Botanists cannot find the wild forms which have given us the cabbage, wheat, and most other small grains, and a host of other important varieties. So, too, the origin of our dogs is as yet unsolved and bids fair ever to remain a mystery.
Scarcely any two botanists, for example, can agree as to the number of roses, still less as to how many species of bramble we possess. Of the latter genus, Rubus, there is one set of forms respecting which it is still a question whether it ought to be regarded as constituting three species or thirty-seven. Mr. Bentham adopts the first alternative and Mr.
As regards the flora of Japan we learned some interesting facts. Though the country is densely populated for its number of square miles, the forest area is four times more extensive than that portion brought under cultivation. Botanists declare its vegetation to be the richest, as well as the most varied, of any portion of the globe.
The wealthy banker, Cliffort, first among amateur botanists of his day, invited Linnæus to visit him at his country-house at Hartecamp. Here he saw the finest garden he had ever looked upon. Cliffort had copies of Linnæus' book and he now insisted that the author should remain, catalog his collection and issue the book with the help of the Plantins, all without regard to cost.
This arrangement has been effected under the superintendence of Monsieur du Jussieu himself, no doubt one of the most scientific botanists thatever has appeared; his residence and that of his family was in the gardens, when I was in Paris twenty years back, and I believe some of them still are concerned in the botanical arrangements of the institution.
With the aid of this key anyone ought to be able to make out to what genus a particular Cactus belongs, and by referring to the descriptions of the species, he may succeed in making out what the plant is. For the classification of Cactuses, botanists rely mainly on their floral organs and fruit.
In a flora so small as the British, 182 plants, generally reckoned as varieties, have been ranked by some botanists as species. Selecting the British genera which include the most polymorphous forms, it appears that Babington's Flora gives them 251 species, Bentham's only 112, a difference of 139 doubtful forms.
It must be remembered that all this time Goethe is pursuing his studies of Physical Science. His little book called "Morphologie," published in 1788, immediately after his return from Italy, is a simple, unaffected, practical, statement of the law of growth of plants, which, though suggested before, had quite escaped the attention of the botanists of repute.
Watson as doubtful species, but which are almost universally ranked by British botanists as good and true species.
Atwater's account of the Prairies, in Silliman's N. A. Journal, vol. i. p. 117. Azara's Voyages, vol. i. p. 373. Dr. He states that botanists are now generally agreed that the cardoon and the artichoke are varieties of one plant. I may add, that an intelligent farmer assured me that he had observed in a deserted garden some artichokes changing into the common cardoon. Dr.
