Fustic - Maclura tinctoria (L.)
Don ex Steud. (synonym: Chlorophora tinctoria),
Family: MORACEAE
Khaki dye tree
by P. Ann van B. Stafford
Fustic tree - Maclura tinctoria is Critically Endangered in the Cayman
Islands.
Fustic is native to the
West Indies and continental tropical America, to Argentina. It grows in Grand Cayman and Cayman Brac. It is DIOECIOUS - male and
female flowers grow on separate trees. Fruits are borne on the female trees
only, which must be sufficiently close to receive pollen from a tree with male
flowers in spikes or catkins.

It is a culturally significant Cayman tree - i
t was exported from Grand
Cayman from the mid-1700’s to the early 1800’s for its yellowish
dye, known as fustic or khaki, which was extracted from the wood. It was used
to dying military uniforms and schoolboys clothing.
1765 Royal Navy officers Remark Books provide information about Cayman. HMS Active anchored off Grand Cayman. Captain Robert Carkett noted that there were about 20 families, most of whom cut Mahogany (Swietenia mahagoni) and Fustic (Maclura tinctoria) which were exported to Jamaica.

Excerpts from Jim Conrad's Naturalist Newsletter. Yucatán, México:
"The greenish "hairs" on
the above "fruits" are styles, which are the "necks" connecting
pollen- receiving stigmas or stigmatic surfaces with the ovaries. Each of the "fruits" in the picture is technically a collection of many actual fruits packed
very closely together."

Wildlife interactions
Fustic is a larval food plant of the Fig Sphinx moth - Pachylia ficus, Family: SPHINGIDAE. Fustic belongs to the same Family: MORACEAE as Wild Fig - Ficus aurea, a well-known larval food plant of Fig Sphinx.

Habitat light, colour variation and ultraviolet reflectance in the Grand Cayman Anole, Anolis conspersus
Joseph M. Macedonia
"Data from a diversity of sources are consistent with the hypothesis that the Grand Cayman anole, Anolis conspersus , is descended directly from Anolis grahami of Jamaica. Although the two species have remained morphologically similar, coloration in A. conspersus has changed considerably from that of its ancestor. The most dramatic difference is seen in dewlap colour, where A. conspersus
has evolved a blue and highly UV-reflective dewlap from the ancestral
orange-and-yellow colour state. In addition, variation in normal
(non-metachrosis) dorsum coloration in A. grahami populations is limited to shades of green (olive, emerald, teal), whereas in A. conspersus
dorsum coloration varies from green to blue and to brown. This
increased colour variation occurs despite Grand Cayman being a small,
relatively featureless island only 35 km in length. Results of this
study suggest that ambient light differences associated with
precipitation-related vegetation structure may have played an important
role in the evolution of A. conspersus body colour variation."

Fustic uses
The wood is very tough and close-grained. Fustic was exported from Grand
Cayman from the mid-1700’s to the early 1800’s for its yellowish
dye, known as fustic or khaki, which was extracted from the wood. It was used
to dying military uniforms and schoolboys clothing.

Historically used for wooden wheels and mill rollers, suitable for furniture and cabinet work; railroad ties; smoking pipes; previously exported as a dye for khaki; bark reportedly medicinal (Mabberley 1997). p.277.

The
wood is very durable and has good weathering characteristics; it is also resistant
to termites.
Heavy
construction (within the tree’s natural range), flooring, furniture, turnings,

Old
fustic was used extensively from about 1600
to 1850, as it produces a strong colour at low cost. During the WW1, fustic was one of the main dyes
used to produce khaki for army
uniforms.
