760 : TILIACEAE 
usually elongated and silique-like, smooth or echinate. Seeds numerous, pendulous or 
horizontal. Embryo folded, in the axis of the endosperm, with entire cotyledons. 
Capsules with 4 tooth-like beaks. 1. C. siliquosus. 
Capsules with a single beak. 2. C. pilolobus. 
1l. Corchorus siliquósus L. Plant glabrous. Stems 3-10 dm. tall, often widely 
branched : leaf-blades oval-ovate to oblong-lanceolate, 1-5 cm. long (those of the ultimate 
branches smaller and rounder), acute or slightly acuminate, serrate, slender-petioled : 
clusters often 2-flowered, short-peduncled: pedicels as long as the peduncles or longer: 
sepals linear or oblong-linear, 5-6 mm. long: petals obovate, 4.5-5 mm. long: capsules 
5-8 cm. long, ascending or spreading, truncate at the apex and each with 4 tooth-like beaks. 
In waste places, peninsular Florida and the Keys. Naturalized from the West Indies. 
2. Corchorus pilólobus Link. Plant minutely pubescent or glabrate. Stems 2-8 
dm. tall, usually sparingly branched, hairy in lines: leaf-blades oblong to lanceolate, 2-5 
cm. long, acute or slightly acuminate, serrate, short-petioled : clusters 2-3-flowered or 
flowers sometimes solitary: pedicels 1-5 mm. long : sepals longer than the pedicels, acumi- 
nate: petals spatulate, about as long as the sepals: stamens commonly 10: capsules 4-5 
em. long, ascending or spreading, flattened contrary to the septa, each short-beaked with 
a single process. 
In waste places, Florida to Texas, Arizona and Mexico. 
2. TRIUMFETTA L. 
Herbs or shrubs. Leaves alternate: blades entire, toothed or 3-5-lobed. Flowers 
perfect, in more or less clustered cymules, axillary or opposite the leaves. Sepals 5, nar- 
row, often mucronate. Petals yellow, 5, convolute, with a pit at the base, or rarely want- 
ing. Stamens numerous or rarely twice as many as the sepals, inserted on an elongated 
receptacle above 5 glands: filaments filiform, unequal, not forked: anthers introrse. 
Ovary 2-5-celled, in the cup-shaped top of the receptacle: stigma 2—5-lobed. Ovules 2 in 
each cavity. Capsule subglobose, echinate, commonly separable into 2-5 carpels. Seeds 
solitary or 2 in each cavity. Embryo with flat, entire cotyledons. 
1. Triumfetta semitriloba Jacq. Annual, stellate-tomentulose. Stems 1-1.5 m. 
tall, branched: leaf-blades ovate, rhombie or suborbicular in outline, 3-6 cm. long, ser- 
rate, angulate or often shallowly 3-lobed, rounded or truncate at the base ; petioles as long 
as the leaves or shorter: panicles narrow, elongated : sepals lanceolate, 5-6 mm. long, ap- 
pendaged below the apex : petals cuneate-spatulate, slightly pubescent at the base : stamens 
often 15 : fruit 4-5 mm. in diameter, 2-celled, "et ies a prickle-armed, the prickles about 
as longas the diameter of the body, hooked at the apex. ©

: 3. TÍLIA L. 
"Trees, possessing a mucilaginous sap and a tough inner bark. Leaves alternate : blades 
oblique, crenate or serrate, petioled. Flowers fragrant, in axillary or terminal cymes whose 
elongated pedunclesare adnate to a conspicuous bract. Sepals5, thickish. Petals 5, naked, 
or with a petaloid scale at the base, imbricated. Stamens numerous, inserted in a short 
receptacle : filaments filiform, forked, often collected in 5 groups, one at the base of each 
scale: anthers extrorse. Ovary superior, 5-celled: stigma 5-toothed. Ovules 2 in each 
cavity. Fruit a berry, but nut-like, with a hard coat. Seeds 1 or 2 in each fruit, with a 
cartilaginous testa. Embryo with crumpled 5-lobed cotyledons. LINDEN. BasswooD-
