Female cone (2.2 inches long) and needles (longest are 4.2 inches) of Pinus thunbergii at Mechanical Engineering on Lasuen Mall. Sairus Patel, 11 Dec 2018

A tall timber tree in Japan but on campus usually dwarfed or quaintly shaped. It has two twisted, green needles to the bundle and the 3-inch cones are not prickly. Conspicuous silky white candles adorn the tree in winter.

See it at Mechanical Engineering (Building 500) at the southmost doorway on Lasuen Mall (location), and just outside both ears of the Oval: two in the juniper bed at the northwest corner of Lathrop Library (location), and one on Lomita Drive near the northeast corner of Herrin Labs (location).

Past specimen locations include the south end of Lathrop Library, where there were several; north of the Bookstore; and the northeast corner of Dinkelspiel Auditorium.

In Palo Alto a specimen at 1290 Cedar Street, near the corner of Hopkins Avenue, was removed 2016.
