Description
California sycamore trees are up to 15, rarely 25 feet high, with a diameter of up to 2 meters rather massive trees, with occasional straight and upright, but usually irregular horizontal or suspended tribes. The stipules are entire, dentate to something. The dark green, thick leaf blade measured along transverse as 10 to 25 inches and is three to fünfgelappt, the lobes are usually longer than broad, the lobes on the leaf approach are usually somewhat smaller. The indentations are broad and strongly concave. The outermost lobe is one to two thirds as long as the leaf blade. The leaf margin is entire, dentate up fine, the extreme end of the leaf is pointed, sometimes rounded. Off-axis is the hairy surface permanently tomentose, close to the axis, the surface is smooth.
Bloom time is spring, fruit period of late autumn. The female inflorescences are in heads of two to seven, rarely from individual flowers, fruit-bearing heads have a diameter of 20 to 25, rarely up to 30 millimeters. The fruits are sessile standing sideways. The rachis of the inflorescence is up to 25 inches long. The fruits are 7-10 mm long achenes, in their approach to find hair with around two thirds of Achänenlänge. The chromosome number is 2n = 42
Dissemination
The California sycamore is spread from California to Mexico at altitudes from sea level to 1500 meters, it is often encountered and is found along streams and in rocky, moist canyons.
System
