Zabel's name tliougli pul>lished wltliout description may be considered 

 sufficiently fixed by the indication of the parentage and seems to be the 

 oldest name for the hybrids between Mains baccata nnd M, pmnila. Mains 

 addringens is simihir to M. robnsia and not always easily distinguished from 

 it, particularly as ternary hybrids like 3/. {baccata X prunifolia) X 

 pumila probably occur, but the generally more pubescent leaves, the 

 shorter stalks of the flowers and fruits, the larfjer, often depressed fruits w^ith 

 more impressed calyx will distinguish this grou]^ of hybrids which Is also 



included under the general term *' Siberian Crabs." Forms like " Hy- 

 slop " (i^ee Beach, Apples of New York, ii. 257, tab.), *' Transcendent " 

 (Beach, 1. c. 266, tab.) and *' Martha " (Beach, 1. c. 2.>9, tab.) may serve 

 as types of this group of hybrids which is from an economic i)oint of view 

 more important than the forms of 3/. robnsia.
