Aesculus glaucescens Sarg.

This is another usually shrubby species from the S.E. United States, also in cultivation, 6 to 10 ft high, but occasionally a small tree up to 30 ft high. Young shoots downy at first only; leaflets five, up to 81⁄2 in. long, 21⁄2 to 31⁄2 in. wide, bright green and downy along the midrib above, rather glaucous and with axil-tufts of hairs beneath, leaf-stalk glabrous. Flowers each over 1 in. long, yellow; calyx bell-shaped, glandular on the margins; petals downy especially on the margins; stamens usually shorter than the petals. This species is closely akin to A. flava, the well-known ‘sweet buckeye’, which has also yellow flowers, but differs in its smaller, more downy leaves and leaf-stalks, and in the much larger fruits.
