Celtis occidentalis – North American hackberry, Nettle tree
Ulmaceae
Celtis occidentalis – North American hackberry, Nettle tree
Un copac cu o coroană de formă neregulată, originar din America de Nord. În câteva locuri, pot fi găsite exemplare care depășesc 20 m, uneori 30 m. Se ramifică destul de jos, formând uneori un arbore cu mai multe tulpini, cu multe crengi puternic căzute. Trunchiul este zimțat, cu crestături adânci și multe umflături. Frunzele sunt alungite ovoidale, cu vârful lung și de culoare verde lucios. Partea inferioară este mai mată. Jumătatea superioară a marginii frunzei este puternic zimțată și ambele fețe ale frunzei se simt aspre. Toamna, devine de un galben auriu izbitor. După o înflorire discretă, apar drupe mici, care se transformă de la portocaliu la negru-violet. Acestea pot rămâne pe copac toată iarna. Lemnul este valoros, iar crengile tinere, flexibile, erau folosite cândva ca biciuri.
