DEWBERRY TYPES 243 



The specific type of Rubus villosus is represented in 

 cultivation by Windom, Geer and Lucretia's Sister. 

 The sub- type known as variety roribaccus is repre- 

 sented by Lucretia ; the type designated as Rubus 

 invisus by Bartel, General Grant and Never Fail. 



Rubus trivialis, or the Southern dewberry, is some- 

 what similar to Rubus villosus (R. CanadensisJ, but 

 distinguished from it by having the main canes thickly 

 beset with stout prickles, which are sometimes dark 

 purple in color. The leaves are firm, smooth and prac- 

 tically evergreen, usually bearing stout prickles on the 

 petioles and midribs. It is common throughout the 

 southern states, and often very productive, bearing at- 

 tractive and desirable fruit. Several varieties belonging 

 to this species have been introduced into cultivation, 

 among which are Manatee, Bauer, and Wilson's White. 

 None of these have become prominent. 



Rubus vitifolius, or the Western dewberry, which is 

 the dewberry of the Pacific slope, is a very peculiar 

 species, bearing some slight resemblance to Rubus vil- 

 losus (R. CanadensisJ, especially in the young growth. 

 The canes are long and slender, however, and the 

 fruiting branches entirely different, the leaflets being 

 broad, coarsely toothed, light green and pubescent 

 both above and beneath, while the other parts are more 

 or less densely covered with straight bristles and glan- 

 dular tipped hairs. As explained in the botanical sec- 

 tion, this is an exceedingly variable species, and many 

 forms are likely to appear should it become prominent 

 in cultivation. The varieties known as Aughinbaugh, 

 Washington Belle, and Skagit Chief belong here. One
