Overview | |
Members of the genus Smilax are dioecious, herbaceous or woody
vines that use stipular tendrils for climbing. Other members are erect
herbs. The stems of Smilax are terete and, in the woody species
are often angled (Radford 1968). Stems are branched, spiny, and prickly
or bristly (Huxley 1992). The leaves are simple and can be either deciduous
or evergreen but are always alternate, petiolate (Radford 1968). Flowers
are white to pale-green, yellow, or brown. They are lateral and may be
solitary or in axillary umbels. There are six separate, free tepals; male
flowers have six free stamens borne at the base, and female flowers have
up to six stamenoids with a superior ovary bearing one to three stigmas
(Huxley 1992). Smilax produce berries that are black, blue, or red
and contain between one and six seeds. The seeds are red, and each is enclosed
in a membranous sac. They may be 3-5mm long and slightly angled or rounded
if they occur alone (Radford 1968).

Kinds | |
Although the genus Smilax contains somewhere
between 200 ( Huxley 1992) and 350 (Everett 1982) species, a complete list
of these has yet to be compiled. The above list includes the species found
in North and South Carolina (Radford 1968) and Georgia (Duncan 1988). There
is slso a list of all species present in Florida.

describe all species in the genus. There does not seem to be a complete
description of the hundreds of tropical and temperate species of Smilax.

Natural history | |
Smilax is a genus containing some 350 species
of woody and herbaceous vines that are climbers or scramblers of the lily
family Liliaceae. Ancient Greeks used the name to describe various plants,
and common names include Wild Sasparilla, Carrion Flower, Greenbrier or
Catbrier or Horsebrier. Most species are native to the tropics, but some
are natives of temperate Asia and North America. The foliage of some species
is used ornamentally as cut greens. It is interesting to note, however,
that the smilax used by florists does not belong in this group. Sasparilla
is obtained from the roots of some tropical species (Everett 1982). Medicinal
uses of sasparilla include prevention of muscular
spasms and cramps, increasing sex drive in females, and serving as a nutritional supplement in
AIDS patients. The species are tolerant to a range of soil and light
variability and propogate by seed or division (Huxley 1992).
Recently, Smilax has been classified as
belonging to the family Smilaceae. Descriptions of the new
classification and corresponding images have been documented.
