Taphrina pruni Taphrina pruni Taphrina pruni is a fungal plant pathogen of blackthorn (Prunus spinosa) that causes the Pocket or bladder Plum gall, a chemically induced distortion of the fruit (sloes), producing swollen on one side, otherwise deformed and flattened fruit gall without a stone. The twigs on infected plants may also be deformed with small strap-shaped leaves. "T. pruni" produces a distinctive tongue-like growth, similar to other closely related species such as "Taphrina alni" on Alder ("Alnus glutinosa") and "Taphrina padi" on Bird Cherry "Prunus padus". The growth is the distorted fruit and not a fungus in its entirety. "T. pruni"
Prunus tangutica Prunus tangutica Prunus tangutica () is a species of wild peach native to China. Based on its fruit traits it had been considered a wild almond, but genetic and morphological studies have shown that it is more closely related to "Prunus persica", the cultivated peach, with its closest relative being "Prunus mongolica". It is a very dense spiny shrub or shrubby tree, usually 1 to 2.5m tall but reaching 4m, preferring to grow on sunny slopes and alongside streams at 1500 to 2600m, but found as high as 3400m. Its flower petals are a pale pink, and its velutinous (velvety)
