Viburnum alnifolium, Marsh. (Viburnum | lantanoides, Michx.). 
Pine Mt., alt. 4,600 ft. Slopes and summit of White Top 
Mt., alt. from 4,800 to 5,678 ft. Along White Top Creek, 
between White Top and the Iron Mts., alt. 2,600 ft. 
The specimens collected at the last locality are remarkable for 
the size of the cymes, some of which measured more than eight 
inches across, and although growing in the damp shade of an 
original forest where the sun seldom penetrates, the drupes were 
fully ripe, while the fruit of bushes two thousand feet higher on 
the mountain side had not yet begun to change color or ripen, 
notwithstanding that they grew in more open places. This obser- 
vation serves to show how great an effect altitude has on a plant, 
even when strong influences are present to counteract it. In the 
valley the shrub reached a height of 5 m.

Hitherto Pennsylvania has been given as the southern limit of 
the range of this species. It will now have to be extended to. 
Southwestern Virginia, as it occurs plentifully at the above cited 
locality. There is, also, a specimen in the Columbia College Her- 
barium, collected by Short in Kentucky.

garis, Michx.). Banks of the Holston River at Marion, alt.
