Importance: S. glauca is one <strong>of</strong>the major sources <strong>of</strong>fast-growing, medium-grade lumber<br />
in <strong>Haiti</strong>. It is well adapted to the agricultural landscape, regenerating naturally<br />
beneath mango and other mature trees. The fast, straight growth and wide adaptability<br />
on shallow soils <strong>of</strong> <strong>Haiti</strong>'s mountains combine to make this tree an attractive choice for<br />
agr<strong>of</strong>orestry. The seed kernel is underutilized and has potential for supplying Haitains<br />
with a source <strong>of</strong> oil.<br />
Taxonomy and Botanical Features: There are 6 species <strong>of</strong> Simarouba in tropical<br />
America, two <strong>of</strong> which are native to <strong>Haiti</strong> (Liogier, 1985). The common S. glauca var.<br />
latifolia is easily distinguished from the less common S. berteroana by the leaves. Those<br />
<strong>of</strong> the former are dark, shiny green above, oblong, and <strong>of</strong>ten notched or smooth at the<br />
apex. S. berteroana leaves are a lighter dull green, lanceolate and have a prominent beak<br />
at the apex (Fig. 5.3 inset). A third Simarouba species, planted during the 1950s and<br />
1960s in the vicinity <strong>of</strong> Lake Peligre, probably was introduced from abroad. Locally<br />
known as doliv, it is distinguished from S. glauca by a smaller bivalved seed and young<br />
growth that is light green rather than reddish. It appears to have a shorter bole and a<br />
heavier crown.<br />
Fwenn is the Creole name derived from the French word for ash (Fraxinus:<br />
Oleaceae). Bwa blan is heard more <strong>of</strong>ten in the northern part <strong>of</strong><strong>Haiti</strong>, whereas fwenn is<br />
used for the species in the south. Where S. glauca co-exists with S. berteroana, the latter<br />
sometimes is referred to as fwenn etranje (foreign ash), though both are native to<br />
<strong>Haiti</strong>. The specimen identified as S. glauca (Ekman 3036), collected in 1925 by Dr.<br />
Ekman near Ganthier, is S. berteroana, as described by Liogier (1985).<br />
Distribution and Ecology: S. glauca is a common native <strong>of</strong> the Greater Antilles,<br />
Florida, Mexico and Central America. It is found mostly in <strong>Haiti</strong> as an associated<br />
species <strong>of</strong>the subtropical moist forest (sensu Holdridge, 1976), occurring from sea level<br />
to about 800 m. It shares the overstory position with the other common trees <strong>of</strong> the<br />
home and humid perennial gardens: mango (Mangifera indica), royal palm (Roystonea<br />
borinquena), avocado (Persea americana), plantain (Musa xparidisiaca) and as shade<br />
for c<strong>of</strong>fee (Fig. 5.2). The species is found on the rocky, shallow calcareous soils <strong>of</strong><br />
mountain slopes and ridges as well as on the deeper soils <strong>of</strong> the ravines and alluvial<br />
plains.<br />
