Phyllocoptes eupadi Phyllocoptes eupadi Phyllocoptes eupadi is a mite that chemically induces a pouch gall to develop as a sub-spherical distortion rising up from the upper surface of the lamina of leaves of blackthorn shrubs "Prunus spinosa" and other "Prunus" spp. Synonyms are "Eriophyes padi" (Nalepa) and "Phytoptus padi prunianus" (Nalepa 1890). The gall's appearance on the upper surface is sub-spherical pustules, hairy and opening below, often clustering along the midrib, but also found over the whole leaf lamina surface and may vary in colour from pale yellow-green to deep red. The adult mite lives on sap, sucked from the cell tissues.
Prunus murrayana rare that no one has seen its fruit since first being scientifically described. Prunus murrayana Prunus murrayana, called the Murray’s plum, is a critically endangered shrub native to Texas. It is found in the Edwards Plateau and the trans-Pecos regions of the state. "Prunus murrayana" is a thorny, deciduous shrub up to 5 meters (almost 17 feet) tall, forming clumps by means of sprouts formed at the base of the plant. Leaves are hairy on both surfaces, usually folding along the midrib. Flowers are white, usually appearing about the same time as the leaves. Fruits are red with white dots,
