Dozens of subspecies may be cultivated in the same garden without any real danger of their intercrossing. They remain as pure as under perfect isolation. It is very interesting to observe the aspect of such types, when growing near each other. Hundreds of rosettes exhibit one type, and are undoubtedly similar.
On the shores and islands of the Indian Ocean and the Malay Archipelago, man is chiefly dependent upon it, but in America it is only of subordinate usefulness. In connection with these facts, it abounds in subspecies and varieties in the East Indian regions, but on the continent of America little attention has as yet been given to its diverging qualities.
It treats of over two hundred subspecies of Madonna worshipped in different parts of south Italy which is divided, for these celestial purposes, into twelve regions, according to the signs of the Zodiac. I warmly recommend this book to all Englishmen desirous of understanding the south.
So, if you desire a knowledge of ornithology, you will need what is known as a bird "key," or "manual," or "handbook" that is, a scientific work that shows how the birds have been classified, with accurate descriptions of all the families, genera, species, subspecies, and varieties, together with the common and scientific names of all the species and brief accounts of their ranges and general habits.
They are all small, the dik-dik being scarcely larger than a rabbit, and they are divided into as many subspecies as the duiker. A list of the different kinds of oribi would take up several lines of valuable space without conveying any illuminating intelligence to the lay mind. We found thousands of oribi on the Guas Ngishu Plateau.
But different horizons or genera, which include under them so many conceptions, may have one common horizon, from which, as from a mid-point, they may be surveyed; and we may proceed thus, till we arrive at the highest genus, or universal and true horizon, which is determined by the highest conception, and which contains under itself all differences and varieties, as genera, species, and subspecies.
These are distinguished within the same genus, and are opposed each to each, for the genus 'animal' has the 'winged', the 'terrestrial', and the 'water' species, and no one of these is prior or posterior to another; on the contrary, all such things appear to be 'simultaneous' in nature. Each of these also, the terrestrial, the winged, and the water species, can be divided again into subspecies.
V. tricolor ammotropha is native near Ystad in Sweden, and the other two forms on Gotland. All three have narrowly limited habitats. The typical tricolored heartsease has remained annual in all its other subspecies. It may be divided into two types in the first place, V. tricolor genuina and V. tricolor versicolor.
Even the seeds exhibit differences in size, shape or color, and of late Martinet has shown, that by the simple means of picking out seeds of the same pattern, pure strains of clover may be obtained, which are of varying cultural value. In this way the best subspecies or varieties may be sought out for separate cultivation.
From a general point of view the variability of the wild species is parallel to that of the cultivated forms to such a degree as to suggest the multiple origin of the former. But a close investigation of this highly important problem has still to be made. The varieties of the cultivated beets are commonly included in four subspecies.
