VITIS 



F. Lvs. only flocculent or cobwebby

 whitish or gray: the white-

 diaphragms and short- 

 pointed Ivs 24. Girdiana 



HH. Grape of Okla.-Texas region, 

 with thin diaphragms and 



prominently pointed Ivs 25. Doaniana 



GO. Ends of shoots (except in V. 

 bicolor), and the unfolding 

 Ivs. distinctly rusty-colored, 

 and the mature Ivs. either rusty 

 or bluish beneath (or some- 

 times becoming green in V. 

 bicolor) : the aestivalian grapes.

through: eastern 28. aestivalis 



jj. Berries larger: western 29. Linsecomii 



FT. Lvs. densely tomentose or felt- 

 like beneath throughout the 

 season, the covering white or 

 rusty white.

 third joint lacking tendril or 

 fl.-cluster). 

 H. Tomentum on under surface of 



Ivs. white 30. candicans 



HH. Tomentum on under surface 



rusty 31. Simpsonii 



GG. Tendrils continuous (at every 



node a tendril or ft. -cluster).. . . 32. Labrusca 

 ^D. Vitis species o/ E. Asia, somewhat 

 intro. for o'rnament, mostly 

 recently, and as yet little known in 

 this country: mostly with lf.- 

 resemblance to N. American 

 species. 

 E. Lvs. divided or compound on some 



of the shoots 33. Piasezkii 



EE. Lvs. undivided or variously lobed. 



F. Sts. glabrous at maturity 34. reticulata 



35. flexuosa 

 FF. Sts. pubescent, tomentose, or 



floccose.

6. rotundif&lia, Michx. (V. muscadlna, V. angulata, 

 V. verrucosa, V. peltdta, Muscadinia rotundifolia, 

 Small). MUSCADINE. SOUTHERN Fox GRAPE. BUL- 

 LACE, BULLIT, or BULL GRAPE. Fig. 1708, Vol. III. Vine 

 with hard warty wood, running even 60-100 ft. over 

 bushes and trees, in the shade often sending down dicho- 

 tomous aerial roots: Ivs. rather small to medium (2-6 

 in. long), dense in texture and glabrous both sides 

 (sometimes pubescent along the veins beneath), cor- 

 date-ovate and not lobed, mostly with a prominent 

 and sometimes an acuminate point (but somewhat 

 contracted above the termination of the 2 main side 

 veins), the under surface finely reticulated between 

 the veins, the teeth and the apex angular, coarse and 



acute, the basal sinus shallow, broad and edentate; 

 petiole slender and (like the young growth) fine-scurfy, 

 about the length of the If .-blade: tendrils (or fl. -clusters) 

 discontinuous, every third node being bare: fr .-bearing 

 clusters smaller than the sterile ones, and ripening 

 from 3-20 grapes in a nearly globular bunch: berries 

 falling from the clusters when ripe, spherical or nearly 

 so and large ( l Ar\ in. diam.), with very thick and tougli 

 skin and a tough musky flesh, dull purple in color with- 

 out bloom (in the 

 Scuppernong va- 

 riety silvery amber- 

 green), ripe in sum- 

 mer and early au- 

 tumn; seeds Y- 

 5-ijin. long, shaped 

 something like a 

 coffee berry. River 

 banks, swamps, 

 and rich woodlands 

 and thickets, S. 

 Del. to N. Fla. and 

 west to Mo., Kans., 

 Texas, and Mex.

7. Munsoniana, Simpson 

 ( Muscadinia, Munsoniana, 

 Small). MUSTANG GRAPE of 

 Fla. BIRD, EVERBEARING, 

 / or EVERLASTING GRAPE. 

 Very slender grower, prefer- 

 ring to run on the ground or over low bushes, more 

 nearly evergreen than the last, flowering more or less 

 continuously: Ivs. smaller, thinner, and more shining, 

 more nearly circular in outline and less prominently 

 pointed, the teeth broader in proportion to the blade 

 and more open or spreading: clusters larger and more 

 thyrse-like: berries a half smaller than in the last and 

 often more numerous, shining black, with a more 

 tender pulp, acid juice, no muskiness, and thinner skin; 

 seeds half smaller than in the last. Dry woods and 

 sands, Fla. at Jacksonville, Lake City, and southward, 

 apparently the only grape on the reef keys; also in the 

 Bahamas. Difficult to distinguish from V. rotundi- 

 folia in herbarium specimens, but distinct in the field. 

 The plant often bears fls. and both green and ripe fr. 

 into Dec.
