Common Hoptree (Ptelea trifoliata), fam. Rutaceae.
A shrub, occurs in the forest. Evidently, it is not an indigenous member of our flora. One bush also grows at the corner of Alma-Atynska and Rohozivska streets. (See map.) It blooms in June, and in autumn the fruits with two or three wings develop. There is no data about any practical use of this plant.
