The gall is a chemically induced distortion of the fruits, which are swollen, hollow, curved and greatly elongated, without a seed or stone, but retaining the style. The twigs on infected plants may also be deformed with small strap-shaped leaves. "Taphrina padi", a 'tongue fungus', produces a distinctive, elongated, tongue-like growth on Bird Cherry, similar to other closely related species such as "Taphrina alni" on Alder ("Alnus glutinosa") and "Taphrina pruni" on Blackthorn ("Prunus spinosa").

Prunus 'Climax' Prunus 'Climax' 'Climax' is a "Prunus" cultivar, considered to be a plum. It was introduced in 1899 by plant breeder Luther Burbank. Burbank devoted a lot of work to hybridizing two plum species, the apricot plum or Simon plum "Prunus simonii" and the Japanese plum "Prunus salicina". He developed a number of cultivars from the hybrid, of which 'Climax' was particularly notable for its importance to the fruit shipping industry of California. The 'Climax' tree is less productive than some other plum cultivars. The fruit is extremely large and heart-shaped, with yellow flesh that is sweet and very juicy. The
