water. The species has recently been obtained for Kew from the 
New York and Missouri Botanic Gardens and from the Arnold 
Arboretum, 
The behaviour of the Zeitneria in cultivation can as yet be only 
surmised, but last year I saw it thriving in the Arnold Arboretum 
and in Highlands Park, Rochester, N.Y. In the former place it 
was planted in peaty soil, and occupied a low moist position, but at 
Rochester it was in an ordinary position on a sunny slope planted in 
a bed of Azaleas and other peat lovers. It was also thriving well in 
ordinary soil in the New York Botanic Garden. All these places 
have much colder winters than ours but the summer heat is greater. 
According to Professor Trelease who gives a full and interesting 
account of this remarkable tree in the Sixth Report of the Missouri 
Botanical Garden, it grows in rich swampy soil which never 
t 
oa we can give it, planted in a peaty soil never allowed to 
ecome dry. 
XLV.—REPORT ON INVESTIGATIONS MADE 
REGARDING “BEECH COCCUS.” 
(Cryptococcus fagi, Birensprung).

INTRODUCTION. 
In view of these conflicting opinions, we were instructed by the 
Director of the Royal Botanic Gardens, Kew, to investigate 
the matter in order to ascertain, if possible, the precise action of 
the Coccus on the Beech, and to obtain an idea of the damage it is 
actually doing or is likely to do. With that object before us visits 
were paid to numerous beech-woods in the Chiltern district, and 
attention has been given to the disease under various conditions in 
different parts of the country. 2
