Juglans cinerea L.
Wallia cinerea (L.) Alef.
Butternut, White Walnut
Butternut is a North American native, related to black walnut. It is an endangered species.
Identification: Trees reach 66' (20 m) in height, rarely 98' (30 m). Trunks are 16-31" (40-80 cm) in diameter. Leaves are 10-20" (25-50 cm) long, and odd pinnate, that is, composed of opposing pairs of leaflets, 10-16 in this case, with an additional leaflet poking out at the end. Leaves have a soft hairlike feel, and a yellowish green. Male flowers are yellow-green catkins (hanging flowers) that are easily missed. Female flowers are bright red, but small and also easily missed. Fruits resemble lemons in shape and limes in color, with a fuzzy exterior that becomes warty later. Growing in groups of two to six, they are 1-2" (3-6 cm) × ¾-1½" (2-4 cm),
