The Black Ash is the slenderest of our forest trees, often reaching the height of seventy feet with a trunk whose diainetei scarcely exceeds a foot. It is the most northern of American ashes flourishing on tiie shores of the Gulf of St. Lawrence. Its inflorescence is polygamous, that is, staminate, pistillate, and perfect flowers may all be found on a single tree, although usual- ly the staminate flowers are borne on a sep- arate ti'ee. In this species the flower is reduced to its lowest terms. Both calyx and corolla are wanting. Many flowers consist simply of two stamens sitting on the top of the flower stem, others are only a pistil. The Black Ash may be known among other ashes by the fact that its leaflets are sessile with the exception of the terminal one. Its samaras dift'er from those of the White Ash in that the wing entirely sur- rounds the body. The taste of the seed is aromatic. The wood is remarkable for its toughness and elasticity. The Indians especially used it in the manufacture of baskets, preferring it to every other. The trunk is often disfig- ured by knobs which are sometimes taken off and made into bowls which when polished show very odd undulations of 220.
