Plant Characteristics:
Glabrous shrub or small tree, branched from base, 1-5 m. high; leaves simple,
coriaceous, oblong to oblanceolate, straight to slightly falcate or asymmetric,
mostly 3-7 (-8) cm. long, .7-1.2
cm. wide, ca. 5-nerved sparsely reticulate between; basal gland evident or not;
fls. in yellow heads solitary in leaf axils or 2-3 in small, axillary or
terminal racemes; legume oblong, curved (to 180 degrees or more), laterally
compressed, ca. 5-7 cm. long, 9-12 mm. wide; valves brown, thin-coriaceous,
expressed over seed, at maturity separating and twisting; seeds black, with a
conspicuous red aril plicate about the seed and 3/4 encircling it.
Habitat:
Urban California. Occasional
as cultivated ornamental. March-August.
Name:
Greek, akakia, from ake, a point because of the prickles on many Acacia species. (Munz, Flora
So. Calif. 797). Greek, Kyklops,
a one-eyed giant. (Jaeger 73).
General:
One plant on the Castaway's Bluffs with several more on the mesa near the
old restaurant site. John Johnson
remembers the specimen on the bluffs from his early days at Newport Harbor High
School which would indicate that it is at least 40 years old at this 1987
writing. In 1996, four small trees
were
found on Shellmaker Island, some of the very few trees there. (my comments).
Acacia cyclops is enumerated by Mathias and McClintock (1963) and
others. It has been tried as a
sand-binder in Golden Gate Park (Jones
1933) but without much success. It
was told at the California Academy of Science that the species has recently been
employed in highway plantings. Sterile
specimens of A. cyclops may resemble
small-leaved forms of the more common A.
melanoxyln, the latter is distinguishable by the more marked reticulation of
the leaves, a basis of comparison. Possibly
A. cyclops hybridizes with other
species in cultivation. (Isely,
Duane. Memoirs of the New York
Botanical Garden, 1973. Vol. 25, pp. 13-37.
Acacia species have been known to have caused hay fever and asthma in
humans. (Fuller 380).
An immense genus, chiefly in subtrop. regions, but especially in Africa
and Australia. (Munz, Flora
So. Calif. 421).
