CERCIS Linnaeus Judas Tree Family Leguminosae Small to moderate, deciduous trees, with alternate, entire, sinijjle, broad-bladed, 5- to T-nerved leaves and somewhat pea-like, colored flow- ers clustered above the past-year's leaf-scars. Fruit an elongated, flat- tened, rather woody, purplish pod with bright, reddish-brown seeds. The slender, zig-zag twigs have jjale to pinkish pith, no terminal bud, oval, scaly, and often stalked lateral buds, and raised and rather dis- tinctly triangular leaf-scars fringed at the top and marked with 3 bundle- traces. The bark is usually scaly. This genus, of which there are S known species, occurs rather widel\ through the temperate and warmer re- gions of the Northern Hemisphere. Its original home, in ancient geologi- cal times, is supposed to have been in Central Asia, from which a large num- ber of species are thought, from fossil records, to have migrated tu many parts of the world, and some of these are considered to be the ancient but direct ancestors of our modern species, which are themselves so old that their history extends back to the Ice Age.
