MAGNOLIAS AND TULIP TREES ATTACKED. 37 



range, but we know of no case where this species has been killed by 

 sapsuckers. One of the magnolias, however, seems to be more 

 seriously affected. 



LIST OF MAGNOLIACE^E ATTACKED. 



Cucumber tree {Magnolia acuminata). — Trees of this species in 

 the grounds of the Department of Agriculture are plentifully punc- 

 tured by sapsuckers, but the work is inconspicuous in their rough 

 bark. All cucumber trees observed in the upper part of Rockfish 

 Valley, Va., bore sapsucker work, tme having several large swollen 

 partial girdles. The species is attacked in West Virginia also (H.). 



Mountain cucumber tree {Magnolia cordata). — Department of 

 Agriculture grounds, District of Columbia. 



Bull bay ( Magnolia grandijlora) . — Many of the trees bordering a 

 long avenue at the Santee Club, South Carolina, bear sapsucker work. 

 Trees in the vicinity of Longbridge, La., are abundantly punctured, 

 and two specimens in the grounds of the Department of Agriculture 

 at Washington have been attacked, one so vigorously that it is dis- 

 figured by numerous girdles. L. L. Wright, of Talladega, Ala., sent 

 in a specimen of sapsucker work from a tree of this species which, he 

 writes, is dying from the effects of whatever it is that is "honey- 

 combing" the bark. From about 2 feet above the ground to the 

 top of the tree it has been girdled at intervals of 15 to 24 inches, the 

 holes varying from contact with each other to three-fourths of an inch 

 apart. At about 8 feet above the ground a double girdle of holes has 

 been made about an inch apart, and so deep as to remove the entire 

 inner bark except for about 6 inches out of a circumference of nearly 

 3 feet. (March 18, 1911.) 



Sweet bay (Magnolia virginiana). — Department of Agriculture 

 grounds, District of Columbia; Church Island, N. C. 



Umbrella tree (Magnolia tripetala). — Illinois (F. 26401). 



Large-leaved umbrella tree ( Magnolia macrophylla) . — Depart- 

 ment of Agriculture grounds, District of Columbia. 



East Asian magnolia (Magnolia yulan). — Department of Agri- 

 culture grounds, District of Columbia. 



East Asian magnolia (Magnolia obovata). — Department of Agri- 

 culture grounds, District of Columbia. 



East Asian magnolia (Magnolia hypoleuca). — Department of 

 Agriculture grounds, District of Columbia. 



Tulip tree (Liriodendron tulipifera) . — This species is a distinct 

 favorite with sapsuckers. Everywhere about Washington are trees 

 bearing abundant sapsucker work. The same is true in the vicinity 

 of Winston-Salem, N. C, and the tree is vigorously attacked in the 

 Rockfish Valley, Va., in West Virginia (Delslow, H. 6687; Pickens, 

 H. 6487a), and in Illinois (F. 26403).
