752 VITACEAE 



1-4 cm. long, rounded but often apiculate at the apex, serrate-dentate, gradually or abruptly 

 narrowed into short petioles or sometimes truncate or subcordate at the base : flower-clusters 

 sessile or nearly so : hypanthium tomentose : sepals 5, rather persistent : drupes subglobose, 

 8-10 mm. in diameter, on recurved pedicels, which are about as long as the diameter of the 

 fruit. 



On plains and prairies, Texas to New Mexico and northern Mexico. 



2. Colubrina reclinata (L'Her.) Brongn. A tree, reaching a maximum height of 

 20 m., with a trunk diameter of about 1.5 m., its twigs and young leaves puberulent, the 

 bark exfoliating in paper-like scales. Leaf-blades leathery, ovate-oblong or rarely oval or 

 obovate, 3-8 cm. long, short -acuminate but usually obtuse, entire, sometimes undulate, not 

 3-nerved, never rusty-pubescent, rounded or somewhat cuneate at the base ; petioles 1-1.5 

 cm. long : flowers in loose glabrate clusters which are usually surpassed by the petioles : 

 calyx glabrate : sepals 5, ovate, slightly acuminate : petals sessile : drupes capsule-like, 

 4-6 mm. in diameter, rather densely clustered. 



In sand, peninsular Florida and the Keys. Also in the West Indies and Bahamas. NAKED WOOD. 



SOLDIERWOOD. 



3. Colubrina colubrina (L. ) Small. An evergreen shrub 2-5 m. tall, the foliage more 

 or less persistently rusty-tomentose. Leaf-blades leathery, ovate, oblong, elliptic, or rarely 

 oblanceolate, 5-15 cm. long, obtuse or short-acuminate, smooth and glabrous above, rusty- 

 pubescent and veiny beneath, 3-nerved, rounded or subcordate at the base ; petioles 5-15 

 mm. long, densely rusty -pubescent : cymes shorter than the petioles, and pubescent like 

 them : calyx 3.5-4.5 mm. broad : sepals triangular-ovate, obtuse : petals spatulate, 1.5-2 

 mm. long, notched at the apex, surpassed by the sepals : drupes obovoid-globose, 8-9 mm. 

 in diameter, on pedicels 8-10 mm. long. [Rhamnus colubrina L., C. ferruginosa Brongn]. 



In sand, southern Florida and the Keys. Also in the West Indies. 



11. GOUANIA Jacq. 



Shrubs, mostly high-climbing by tendrils, with slender elongated branchlets. Leaves 

 alternate : blades petioled, commonly leathery, stipules elongated, deciduous. Flowers 

 polygamous, in axillary or terminal, sometimes panicled spikes or racemes, whose rachis 

 often gives off tendrils. Hypanthium obconic. Sepals 5, spreading. Disk epigynouss 

 filling the hypanthium, 5-angled or produced into 5 horns, glabrous or pubescent. Petal, 

 5, inserted in the sinuses of the edge of the disk, shorter than the calyx : blades hooded. 

 Stamens 5 : filaments hidden by the petals. Ovary immersed in the disk, 3-celled : styles 

 3, united at the base. Drupe capsule-like, leathery, 3-winged, separating into 3 nutlets. 

 Seeds plano-convex, with a shining horny testa. Endosperm thin. 



1. Gouania Domingensis L. A slender climbing shrub, with more or less pubescent 

 branches. Stems much branched, elongated : leaf-blades oval or elliptic verging to ovate, 

 3-9 cm. long, short-acuminate, with obtuse commonly coarsely serrate blunt teeth, 

 rounded or subcordate at the base, glabrous on both surfaces ; petioles 3-12 mm. long, 

 clothed with appressed hairs : spikes interrupted, 6-15 cm. long, villous-tomentose, pro- 

 ducing tendrils at or near the base : flowers yellow : drupes subglobose, 3-winged, about 1 

 cm. broad (including the wings), finally separating into three 2-winged nutlets. 



In sand, southern Florida and the West Indies. Also in Mexico. 



FAMILY 2. VITACEAE Lindl. GRAPE FAMILY. 



Shrubby or tree-like vines, usually climbing by means of tendrils, possessing 

 copious watery and sometimes gelatinous sap. Stems swollen at the nodes, 

 clothed with a shreddy or close bark. Leaves simple or compound, the lower 

 ones opposite, the upper alternate : blades petioled, coarsely toothed or lobed. 

 Stipules present or wanting. Inflorescence axillary, cymose, umbel-like, race- 

 mose, thyrsoid or panicled. Flowers often fragrant, perfect, polygamous or dioe- 

 cious, regular. Calyx of 4-5 sepals or sometimes obsolete. Disk filling the hypan- 

 thium or wanting. Corolla of 4-5 valvate and often caducous petals sometimes 

 cohering by their tips. Androecium of 4-5 stamens opposite the petals. Fila- 

 ments distinct. Anthers introrse. Ovary 2-celled or sometimes 3-6-celled, free 

 or adnate to the disk at the base. Styles united. Stigma capitate or peltate. 

 Ovules 1-2 in each cavity, anatropous, ascending. Fruit a berry, often with a 

 very watery pulp. Seeds 1-2 in each cavity, erect, with a bony testa. Endo-
