smaller than the sterile oues, aud ripening from 3 to 20 grapes in a nearly globular bunch • 

 berries falling from the cluster when ripe, spherical or nearly so and large (half inch to 

 inch iu diameter), with very thick and tough skin and a tough musky flesh, dull purple in 

 color without bloom (in tlie Scuppernong variety silvery amber-green), ripe in summer and 

 early autumn; seeds i to f inch long, shaped something like a coffee berry. — Fl. ii. 231 ;

V. Munsoniana, Simpson. (Mustang Grape of Florida, Bird or Everhearing 

 Grape.) Very slender grower, preferring to run on the ground or over low bushes, more 

 nearly evergreen than the last, flowering more or less continuously: leaves smaller, thinner, 

 and more shining, more nearly circular iu outline and less prominently pointed ; the teeth 

 bro.ader in proportion to the blade aud more open or spreading : clusters larger and more 

 thyrse-like ; berries a half smaller than in the la.st and often more numerous, shining black, 

 with a more tender pulp, acid juice, no muskiuess, and tliinner skin ; seeds half smaller than 

 in the last. — J. H. Simpson in Munsou, Addr. on Am. Grapes, Lansing, 1886, 5 (lieing a 

 reprint and revision of a paper in Proc. Am. Pom. Soc. xx., in which this grape is referred 

 to r. Floridana, Raf.) ; Munson, Proc. Soc. Prom. Agr. Sci. 1887, 59, Wild Grapes N. A.

 Vitic. 30. — Dry woods and sands, Florida, at Jacksonville, Lake City, and southwards, 

 apparently the only grape on the reef keys. (Also in the Bahamas.) Difficult to distin- 

 guish from V. rotimdifolia in herbarium specimens, but distinct in the field. 



§ 2. EuviTis, Planch. Bark without distinct lenticels, on the okl wood 

 separating in long thin strips and fibres : nodes provided with diaphragms : ten- 

 drils forked; flower-clusters mostly large and elongated: seeds pyriform. — 

 Vignes Am. 102, & in DC. Monogr. Phaner. v. 322. 



* Green-leaved Grapes, mostly marked at maturity by absence of prominent white, 

 rusty, or blue tomentum or scurf or conspicuous bloom on the leaves beneath (under sur- 

 face sometimes thinly pubescent, or minute patches of floccose wool in the axils of the 

 veins, or perhaps even cobwebby) ; the foliage mostly thin : tendrils intermittent, i. e., 

 every third joint bearing no tendrils (or inflorescence). V. cinerea and V. Arizonica are 

 partial exceptions and might be looked for in * *. 



-1— Vulpina-WkQ grapes, characterized by thin light or bright green mostly glossy leaves 

 (which are generally glabrous below at maturity save perhaps iu the axils of the veins 

 and in V. Champini) with a long or at least a prominent point and usually long and large 

 sharp teeth or the edges even jagged. 



++ Leaves broader than long, with truncate-oblique base ( V. Treleasei might be sought here). 



V. rupestris, Scheele. (Sand, Sugar, Rook, Bush, or Mountain Grape.) Shrub 2 to 

 6 feet high, or sometimes slightly climbing, the tendrils few or even none, diaphragms plane 

 and rather thin : leaves reniform to reniform-ovate (about 3 to 4 inches wide and two 

 thirds as higli), rather thick, smooth and glabrous on both surfaces at maturity, marked by 

 a characteristic light glaucescent tint, the sides turned up so as to expose much of the 

 under surface, the base only rarely cut into a well marked sinus, the margins very coarsely 

 angle-toothed, the boldly rounded top bearing a short abrupt point and sometimes two 

 lateral teeth enlarged and suggesting lobes : stamens in fertile flowers recurved laterally or 

 rarely ascending, those in the sterile flowers ascending : clu.ster small, slender, 0])en and 

 branched ; berries small (^ to ^ inch in diameter), purple-black and somewhat glaucous, 

 pleasant-tasted, ripe in late summer; seeds small and broad. — Linna;a, xxi. 591 ; Planch,
