 lobed, dull and glabrate above, densely white-woolly beneath ; petioles about as long as

 colored to dark purple, with a tough skin and disagreeable taste : seeds broadly pear-shaped, 

 6 mm. long, each with a conspicuous raphe.

 GRAPE. 



20. Vitis coriacea Shuttlw. A high-climbing vine, with rusty young foliage. Leaf- 

 blades reniform to suborbicular in outline, 3-10 cm. broad, shallowly toothed or angularly

 beneath, cordate or truncate and subcordate at the base ; petioles i as long as the blades or 

 of equal length : panicles 5-12 cm. long : berries subglobose, less than 10 mm. in diameter, 

 pleasantly acid : seeds broadly pear-shaped, 6 mm. long, each with a conspicuous raphe. 



In sandy soil, peninsular Florida. Spring ; fruit ripening in late summer or fall. 



21. Vitis Simpsoiiii Munson. A shrubby vine climbing over bushes. Leaf-blades 

 suborbicular in outline, 5-18 cm. broad, prominently or mostly deeply 3-5-lobed, and 

 shallowly toothed, glabrate above, more or less densely brownish white-tomentose beneath, 

 cordate, long-petioled : panicles 5-10 cm. long, usually compact : berries commonly 15 

 mm. in diameter, black, mostly 4-seeded : seeds broadly pear-shaped, 5-6 mm. long, each 

 with a conspicuous raphe. 



In sandy soil or especially on shejl mounds near the salt water, peninsular Florida. Spring ; fruit 

 ripening in September. 



22. Vitis Labi usca L. A vigorous high-climbing vine with densely tomentose foliage. 

 Leaf-blades thickish, suborbicular to broadly ovate, mostly longer than broad, shallowly 

 toothed, or scalloped, otherwise entire, or 3-lobed near the apex, becoming glabrous above, 

 densely tomentose beneath, with a rounded or acute sinus : petioles more than J as long as 

 the blades : panicles 5-12 cm. long, usually simple : berries globose, 1.5-2 cm. in diameter, 

 amber to purple, with a slight bloom, the skin and tough pulp sweet and musky, or 

 astringent : seeds abruptly constricted near the base, 7-10 mm. long, each with a conspicu- 

 ous raphe.
