 preferably in a fairly dry situation. 



Position of the Gall.— At the top of the main stem ; some- 

 times on the lateral shoots. 



Manner of Growth.— Singly ; glabrous ; mostly pyramidal 

 in shape. 



Colour.— Pale green, yellowish, chocolate-brown. 



Average Dimensions of a Mature Specimen. 

 Height, 8 mm.; girth, 15 mm. 



May be sought during the months of June to October. 



The Growth is complete by the end of August. 



These galls are found plentifully on plants growing on the 

 golf-links at Camber, near Rye, Sussex. The ground is near to 

 the sea, and is very sandy owing to its close proximity to the 

 sand dunes which skirt the sea-shore at that part of the coast. 



The galls are deeply grooved or furrowed from base to apex. 

 Some are almost globular in shape, others are elongated, while a 

 few are like a miniature cupola. 



The author is indebted to Miss Ethel Sayer for her kindness 

 in sending some very fine specimens from Mundesley, Norfolk. 



The illustration is of specimens gathered at Camber, Sussex, 

 by the author.
