Some botanists even prognosticate that more than two thousand species of palms will yet become known. Of the six hundred species known, about half belong to the Old World, and half to America. In America they are chiefly found growing on the Continent although several species are natives of the West India Islands while on the Eastern hemisphere the greatest number of species belong to the islands.
Clothed as it is with clinging ivy and climbing roses, the house suggests an effect of both stateliness and rusticity. Bartram was a farmer, but his interest in plants, shrubs and trees was such that he became one of the greatest botanists of his day.
How confidently would the superficial nay, even careful examination of one of the old-time botanists have interpreted its structure: "How simple and perfect the structure! Observe how the anthers are placed so that pollen shall naturally fall directly on the stigmas and fertilize them!"
As we have intimated, there are several hundred varieties known to botanists, most of which can be identified on Mexican soil, this being their native climate. No matter how dry the season, they are always juicy. It is said that when cattle can get no water to drink, they will break down the cacti with their horns and chew the thick leaves and stalks to quench their thirst.
After all this abuse of the giant thistle, the Cardo asnal of the natives and Carduus mariana of the botanists, it may sound odd to say that a "thistle year" was a blessing in some ways.
Tropical treasures from Nature's storehouse, collected by successive Directors, are arranged with care and precision characteristically Dutch. It was established in 1817 by Professor Reinwardt, and many distinguished botanists who have left their mark in the scientific world studied here and added to the collections.
It is noteworthy that it has generally been the botanists who have especially supported these views of saltatory evolution in a definite direction and according to internal law, who have therefore tended to react most strongly from Darwinism.
For instance, the blue and red pimpernel, which are considered by most botanists as varieties, are said by Gartner to be quite sterile when crossed, and he consequently ranks them as undoubted species. If we thus argue in a circle, the fertility of all varieties produced under nature will assuredly have to be granted.
And it was known to some observant botanists in the last century, although forgotten or discredited in this, that an insect caught on the viscid glands it has happened to alight upon is soon fixed by many more not merely in consequence of its struggles, but by the spontaneous incurvation of the stalks of surrounding and untouched glands; and even the body of the leaf had been observed to incurve or become cup-shaped so as partly to involve the captive insect.
In North America it follows the water-courses to the limit of the temperate zone, enters the tropics, crosses the equator, and appears in the mountains of Peru and Chili.... The books record one hundred and sixty species in the world, and these sport and hybridize to their own content and to the despair of botanists.
