A small tree 12—20 feet high and 6 — 10 inches in diameter, with nume- 
rous expanding branches, and the old bark thickly studded with prickles, 
very acute at the summit, dilated at base, ovoid, and sometimes an inch in 
their longest diameter. Leaves alternate unequally pinnate, leaflets (3 — 4 
pair) obliquely lanceolate, generally equal at base, sparingly dotted, lucid on 
the upper surface, the terminal leaf not oblique. Flowers in terminal pani- 
cles composed of small umbels, the florets on pedicels about 5 lines long. 
Calyx very small, 5-parted. Corolla 5-petalled, petals oval, much longer 
than the calyx. Stamens variable, more frequently 5 than any other num- 
ber, longer than the corolla. Styles in the fertile flowers 2 or 3, incurved 
gibbous. Stigmas simple. Capsules 1-seeded. 
Grows in dry sandy soils, confined I believe to the sea-coast. The leaves 
are very aromatic and pungent. Prickly Ash. 
Flowers June.
