346 THE EVOLUTION OP OUR NATIVE FRUITS 



The MAYNARD, a Kansas variety, is one of the nov- 

 elties. It has a peculiar habit, intermediate between 

 Rubus villosus and the blackberry, but it seems to be 

 nearer the former. Card considers it a hybrid. 



2. The Lucretia sub -type, variety roribaccus 

 (Fig. 71). As compared with Rubus villosus proper, 

 this variety is a much larger and stronger grower; 

 leaves large and the margins doubly serrate with small 

 teeth, and more or less notched or jagged : leaflets 

 broad at or below the middle, sometimes triangu- 

 lar-ovate ; peduncles or flower stems much longer, 

 straighter and stouter, more erect, habitually more 

 numerous and more conspicuously overtopping the 

 leaves ; flowers very large and showy (often two 

 inches across) ; sepals uniformly larger, some of them 

 much prolonged and leaf -like and conspicuously lobed 

 (sometimes becoming an inch long and wide) ; fruit 

 much longer and larger as a rule, and more or less 

 thimble -shaped. Strong forms of Rubtis villosus 

 itself often look much like this in foliage, but I 

 have never seen any in which there was such a de- 

 velopment of long flower stems, large flowers and 

 fruits, and large sepals. The Lucretia appears to 

 be the only variety of this sub -type in cultivation. 



The Bartel type, or Rubus invisus, is particularly 

 distinguished by the large and nearly simple teeth of 

 the leaves and the very long and ascending flower 

 stems. Canes stout and stiff, often partially ascending; 

 leaflets larger than in R. villosus, broad and thin, 

 smooth or very nearly so, the teeth usually very large, 

 simple and often rounded and terminating in a minute 

 point ; peduncles or flower stems long and straight ; 

 young flower buds commonly bearing a prominent tip
