[QUINARIA Raf. Am. Man. Grape-vines, 6. 1830. Not Lour. 1790.] 

 Climbing or trailing woody vines, the tendrils often tipped with adhering expansions 

 (disks), or sometimes merely coiling, our species with digitately compound leaves, the leaf- 

 lets 5-7. Flowers perfect, or polygamo-monoecious, in compound cymes or panicles. Petals 

 5, spreading. Hypogynous disk obsolete or wanting in our species. Stamens 5. Ovary 2- 

 celled; ovules 2 in each cavity; style short, thick. Berry i-4-seeded, the flesh thin, not edible. 



About 10 species, natives of eastern North America and Asia. Besides the following, another 

 occurs in Texas.

 Parlhenocissus quinquefolia Planch, in DC. Mon. 



Phan. 5: Part 2, 448. 1887. 



High-climbing or trailing. Tendrils usually 

 numerous, and provided with terminal adhering 

 expansions, the vine sometimes supported also 

 by aerial roots; leaves petioled, digitately 5-folio- 

 late (rarely 7-foliolate); leaflets stalked, oval, el- 

 liptic, or oblong-lanceolate; 2 / -6 / long, acute or 

 acuminate, narrowed at the base, coarsely 

 toothed, at least above the middle, pale beneath, 

 dark green above, glabrous or somewhat pubes- 

 cent; panicles ample, erect or spreading in fruit; 

 berries blue, about 6" in diameter, usually 2-3- 

 seeded; peduncles and pedicels red. 



In woods and thickets, Quebec to Manitoba, Flor- 

 ida, Texas and Mexico. Also in Cuba. July. Fruit 

 ripe in October. The foliage turns deep red in 

 autumn. Erroneously called Woodbine. 



Parthenocissus quinquefolia laciniata Planch, in DC. Mon. Phan. 5: Part 2, 449. 1887. 

 Ampelopsis quinquefolia var. viiacea Knerr, Bot. Gaz. 18: 71. 1893. 

 Parthenocissus vitacea A. S. Hitchcock, Spring PL Manhattan, 26. 1894. 



Tendrils mostly without terminal adhering disks, the vine not high-climbing; leaves more deeply 

 and sharply toothed; fruiting panicles described as drooping. Ohio to Iowa, Kansas and Colorado. 

 Perhaps specifically distinct. 



Parthenocissus tricuspidata (Sieb. & Zucc. ) Planch., the Ampelopsis Veitchii of the gardeners, 

 a Japanese vine, clinging to walls by its very numerous disk-tipped tendrils, has the leaves sharply 

 3-lobed or sometimes 3-divided; it is freely planted for ornament. 



Family 73. TILIACEAE Juss. Gen. 289. 1789. 



LINDEN FAMILY. 



Trees, shrubs or rarely herbs, with alternate (rarely opposite) simple leaves, 

 mostly small and deciduous stipules, and axillary or terminal generally cymose 

 or paniculate flowers. Sepals 5, rarely 3-4, valvate, deciduous. Petals of the 

 same number, or fewer, or none, alternate with the sepals, mostly imbricated in 

 the bud. Stamens oo, mostly 5-io-adelphous; anthers 2-celled. Ovary i, ses- 

 sile, 2-io-celled; style entire or lobed; ovules anatropous. Fruit i-io-celled, 

 drupaceous or baccate. Embryo straight, rarely curved; cotyledons ovate or 

 orbicular; endosperm fleshy, rarely wanting. 



About 35 genera and 245 species, widely distributed in warm and tropical regions, a few in the 

 temperate zones. r 



i. TILIA L. Sp. PI. 514. 1753. 



Trees, with serrate cordate mainly inequilateral leaves, and axillary or terminal, cymose 

 white or yellowish perfect flowers, the peduncles subtended by and partly adnate to broad 

 membranous bracts. Sepals 5. Petals 5, spatulate, often with small scales at the base. 

 Stamens co; filaments cohering with the petal-scales or with each other in 5 sets. Ovary 

 5-celled; cells 2-ovuled; style simple; stigma 5-toothed. Fruit dry, drupaceous, globose or 

 ovoid, indehiscent, i-2-seeded. Seeds ascending; endosperm hard; cotyledons broad, 5-lobed, 

 corrugated. [The ancient Latin name.]
