Trees -- North America
Leaves dark yellow-green and lustrous, 5°—6° long, often 7° wide,
divided nearly to the middle into narrow divided segments, with
thickened pale margins separating into long thin fibres, with ligules
about 6′ long; petioles 7°—8° long, 1½′ wide at the apex. Flowers:
spadix 7°—8° long, with stout ultimate divisions; flowers in Texas
appearing in March or April in the axils of persistent bracts half as
long as the perianth. Fruit ripening early in the summer, globose, often
2 or 3-lobed; seeds nearly ½′ broad and ¼′ wide, dark chestnut-brown,
with a broad shallow basal cavity, and a conspicuous orange-colored
hilum.
A tree, with a trunk 30°—50° high, often 2½° in diameter, and a broad
head of erect ultimately pendulous leaves. Wood light, soft, pale brown
tinged with red, with thick light-colored rather inconspicuous
fibro-vascular bundles, the outer rim 1′ thick, soft, and light colored.
On the Gulf coast the trunks are used for wharf-piles, and on the lower
Rio Grande the leaves for the thatch of houses.
Distribution. Rich soil of the bottom-lands on the Bernado River,
Cameron County, and near the mouth of the Rio Grande, Texas, and
southward in Mexico in the neighborhood of the coast.
Frequently planted as a street tree in the towns in the lower Rio Grande
valley.
4. WASHINGTONIA H. Wendl.
Trees, with stout columnar stems and broad crowns of erect and spreading
finally pendulous leaves. Leaves flabellate, divided nearly to the
middle into many narrow deeply parted recurved segments separating on
the margins into numerous slender pale fibres; rachis short, slightly
rounded on the back, gradually narrowed from a broad base, with concave
margins furnished below with narrow erect wings, and slender and acute
above; ligule elongated, oblong, thin and laciniate on the margins;
petioles elongated, broad and thin, flattened or slightly concave on the
upper side, rounded on the lower, armed irregularly with broad thin
large and small straight or hooked spines confluent into a thin bright
orange-colored cartilaginous margin, gradually enlarged at base into
thick broad concave bright chestnut-brown sheaths composed of a network
of thin strong fibres. Spadix interfoliar, stalked, elongated,
paniculate, with pendulous flower-bearing ultimate divisions and
numerous long spathes. Flowers perfect, jointed on thick disk-like
pedicels; calyx tubular, scarious, thickened at base, gradually enlarged
and slightly lobed at apex, the lobes imbricated in the bud; corolla
funnel-formed, with a fleshy tube inclosed in the calyx and about half
as long as the lanceolate lobes thickened and glandular on the inner
surface at the base, imbricated in the bud; stamens inserted on the tube
of the corolla, with free filaments thickened near the middle and
linear-oblong anthers; ovary 3-lobed, 3-celled, with slender elongated
flexuose styles stigmatic at apex; ovules lateral, erect. Fruit a small
