Cultivated at the Arnold Arboretum, of unknown origin, specimens collected 

 September 24, 1908, June 2, 1909, October 30, 1911, May 28 and September 13, 1912, 

 J. G. Jack; September 5, 1918, and June 1, 1920, A. RehJcr. 



This hybrid which was first observed in 1908 in the Arnold Arboretum 

 by Professor J. G. Jack in several individuals of unknown origin, is clearly 

 intermediate between Viburnum Lentago and F. prunifolium and appar- 

 ently a hybrid between these two species which bloom at about the same 



if' 



From F- Lentago 



it differs chiefly in the less long-acuminate leaves, those below the inflores- 

 cence often acutish or obtusish, in their finer serration, in the less pale under 

 side with less conspicuous vcinlets, in the less broadly margined petioles 

 with the margin not or little wavy and revolute, although sometimes slightly 

 so at maturity, in the shorter winter-buds and in the denser habit. From 

 V. jpnmiJoUwn it differs in the more or less acuminate leaves with the 

 veins more prominent beneath, in the margined petioles, in the usually 

 sessile, slightly lepidote inflorescence, the smaller, less pure white flowers 

 and in the slenderer branches. As it grows in this Arboretum it forms a 

 handsome rather compact round bush 3-4 m. tall with slender spreading 

 branches, quite different from V. pmrnfoUum which is more tree-like with 

 stout rigid branches and often spinescent spurs; it is also different from 

 V. Lentago which forms a taller arborescent shrub with a looser head of 

 spreading and arching branches.
