VARIETIES OF BLACKBERRIES AND DEWBERRIES 431 



of which it is one parent, promise much. Vigor and productive- 

 ness of plant are the characters for which it should be used in 

 hybridization. 



677. Iceberg. — One of the few white blackberries worth try- 

 ing, Iceberg is little more than a curiosity in the East, but has 

 some value in California as a fruit for home use. At Geneva, 

 New York, the plants must be protected against winter-killing. 

 The variety originated with Luther Burbank about 1895. The 

 plant is described as much like that of Lawton, while the berries 

 in California are said to be large, amber-white, soft, and of 

 very good quality. 



678. Kittatinny has an unbroken record of more than a half 

 century as a standard commercial blackberry in the United 

 States from the Atlantic to the Pacific. Possibly no variety has 

 been or is more widely and largely grown. It equals the best 

 representatives of its kind in quality of fruit. Two faults mar 

 an otherwise excellent variety; the plants are not hardy in cold 

 climates, and are very susceptible to rust where that disease is 

 rife. Kittatinny comes from the mountains of the same name 

 in New Jersey, and was introduced by E. Williams about 1865. 



Plants tall, vigorous, upright-spreading, productive, half-hardy; canes 

 numerous, stocky; furrowed, reddish-broAvn, -with long, strong, straight 

 prickles. Leaflets large, oblong-lanceolate, pubescent above and beneath. 

 Flowers l^/i inches in diameter, 6-8, in rather short, open, leafy racemes. 

 Fruit early midseason, medium size, oblong, variable in size and shape, 

 jet black; core cylindrical, soft; drupelets large, round; flesh sweet, rich; 

 quality very good; seeds small, soft. 



679. Lawton. New RocheUe. — Lawton was the second va- 

 riety of this fruit introduced. It is still grown widely on the 

 Pacific slope and somewhat in the East, being especially well 

 liked for canning. It has lost commercial importance in the 

 East, however, because the plants do not withstand cold well and 

 are susceptible to rust. The fruit is not ripe until jet-black, 

 when the quality is of the best. Lawton was introduced by 

 William Lawton, New Rochelle, New York, about 1848. 



Plants stocky, vigorous, productive, tender to cold, susceptible to rust, 

 with numerous large prickles. Fruit late midseason, large, jet-black, be-
