Ulmus pumila Siberian elm
Siberian elm is distinguished from Chinese elm by the irregularly ridged bark and the fruit, which ripens in early summer as a papery oval about ½ inch across. There is a deep notch that reaches almost to the seed lodged in the middle.
Specimens can be seen at the service station (Serra Street at Campus Drive East), in the courtyard behind the northwest corner of the Outer Quad, and on Escondido Road at the west end of Wilbur Hall (Wilbur Hall tree map). In Palo Alto, Siberian elm is the street tree at 1570 Bryant Street.
Name derivation: Ulmus – classical Latin name for the elm.
