In different parts of the Union the trailing blackberry, or dewberry, runs into many forms or types, some of which have been decided to be - distinct species. The most important of the four species is the Northern Dewberry (Rubus villosus). This seems nearly allied to the cultivated blackberries, as natural hybrids often occur, and it has given several of our best varieties. The Southern Dewberry (Rubus trivialis) has also given some varieties of value which have become commercial in the South. The Western species (Rubus vitifolius) has also given some cultivated varieties.
Large, rich, juicy, subacid, and firm enough for shipping. This was the first-named variety tested by the writer, and is still one of the desirable ones for Northern culture. Illinois.
Very large, conical, sometimes one and one-quarter inches long; color dark red; quality scarcely good for dessert use, but is much improved by stewing and makes a desirable sauce. It is here classed with the dewberries as it has the habit of growth of that class, but it is. supposed to be a cross between the Texas Early blackberry and a red raspberry. By covering in winter this variety is grown successfully in the southeastern States and as far north as New Jersey.
Very large and long, specimens in some cases two and three-eighths inches long. Prof. Wickson states: "The fruit is more acid than the Lawton, but when perfectly ripe is sweet and of superior flavor." A hybrid produced on the west coast by crossing the native species of California with pollen of Crandall's Early of Texas, which has something of a shrubby habit. The Mammoth at first throws up thick upright shoots. They then drop to the ground, and often run, if unchecked, twenty-five feet in a season. It is only propagated from the tips like our Blackcaps. This will probably succeed well in the Gulf States.
Very large, roundish conical; color jet black; quality very good. Plant trailing when young, but later it attains a stronger habit and becomes partially upright. This variety has become commercial in the South on a large scale, and it is grown as far north as Missouri and Ohio. Texas.
