VITIS 



23. bicolor, Le Conte ( V. argentifdiia, Munson). Blue 

 Grape, or Soimer Grape of the North. Fig. 2701. A 

 strong, high-climbing vine, with mostly long internodes 

 and thick diaphragms, the young growth and canes 

 generally perfectly glabrous and mostly (but not always) 

 glaucous - blue, tendrils 

 and petioles very long: 

 Ivs. large, roundcordate- 

 ovate in outline, glabrous 

 and dull above and very 

 heavily glaucous -blue 

 below, but losing the 

 bloom and becoming dull 

 green very late in the 

 season, those on the 

 young growth deeply 3- 

 ."i-lobed and on the older 

 growths shallowly 3- 

 lobed, the basal sinus 

 running from deep to 

 shallow, the margins 

 mostly shallow -toothed 

 or sinuate - toothed (at 

 least not so prominently 



notch-toothed as in r. astivalif:): cluster mostly long 

 and nearly simple (sometimes forked), generally with 

 a long or prominent peduncle: the purple and densely 

 glaucous berries of medium size ( J^in. or less in diam. )', 

 sour but pleasant-tasted when ripe (just before frost): 

 seeds rather small. Abundant northwards along streams 

 and on banks, there taking the place of y. testivalis. 

 Ranges from New Eng. and 111. to the mountains of 

 W. North Carolina and to W. Tenn.-Well distinguished 

 from y. (eslivalis (at least in its northern forms) by the 

 absence of rufous tomentura, the blue-glaucous small- 

 toothed leaves, and long petioles and tendrils. It has 

 been misunderstood because it loses its glaucous char- 

 acter in the fall. 



24. Caribasa, DC. Pig. 2702. Climbing, with flocculent- 

 woolly (or rarely almost glabrous) and striate shoots: 

 tendrils rarely continuous : Ivs. cordate-ovate or even 

 broader and mostly acuminate-pointed, sometimes ob- 

 scurely angled above ( but never lobed except now and 

 then on young shoots), becoming glabrous above but 

 generally remaining rufous-tomentose below, the mar- 

 gins set with very small, mucro-tipped sinuate teeth: 

 cluster long and long-peduncled, generally large and 

 very compound : berry small and globose, purple: seed 

 obovate,grooved on the dorsal side. Awidely distributed 

 and variable species in the American tropics, running 

 into white-leaved forms (as in V. Blancoi, Munson). 

 Little known in the United States: La., Lake City, 

 N. Fla., swamp near Jacksonville, Fla.

 on the strong shoots and more or less indistinctly lobed 

 or only angled on the normal growths, the margins

 Grape. Plant strong 

 and high climbing, with 

 densely woolly young 

 growth(which is gener- 

 ally rusty-tipped), and 

 very thick diaphragms: 

 Ivs. medium in size 

 and more or less poplar-like, ranging from reniform- 

 ovate to cordate-ovate or triangular-ovate, dull above 

 but very densely white-tomentose below and on the 

 petioles, the basal sinus very broad and open or usually 

 none whatever (the base of the leaf then nearly trun- 



laterally reflexed: cluster small, mostly branched, bear- 

 ing a dozen to twenty large [% in. or less in diam.) 

 purple or light-colored or even whitish berries, which 

 have a thick skin and a very disagreeable fiery flavor: 

 seeds large, pyriform. E. Texas, mostly on limestone 

 soils. 



Var. coriicea, Bailey ( V. cori&cea, Shnttl.). Leather- 

 leaf or Calloosa Grape. Fig. 2703. Differs from the 

 species chiefly in bearing much smaller (about % in. 

 in diam. ) thinner-skinned and more edible Grapes with 

 mostly smaller seeds, and perhaps a less tendency to 

 very deep lobing in the Ivs. on young shoots and pos- 

 sibly rather more marked rustiness on the young 

 growths. Florida, chiefly southward, in which range 

 various Texan plants reappear.— The more agreeable 

 quality of the fr. is probably the result of a more 

 equable and moister climate. 



26. Simpsoni, Munson. Distinguished by mostly 

 much-cut Ivs. on the young shoots and comparatively 

 thin, large and large-toothed ones on the main shoots, 

 rusty - white tomentum below and very prominently 

 brown-toraentose young growths,— the character of the 

 Ivs. and tomentum varying widely, the foliage some- 

 times becoming almost blue-green below. Fla. -This 

 is likely a hybrid of V. cpstiralis and r. candicans, var. 

 coriacea. Some forms of it are very like V. Labrtisca, 

 and might be mistaken for that species. 



FP. Tendrils mostly continuous (o tendril or inflor- 

 escence at every node).

 Grape. Skunk Grape. Figs. 949, 950, Vol. II. A strong 

 vine, climbing high on thickets and trees : young shoots 

 tawny or fuscous, with much scurfy down: Ivs. large 

 and thick, strongly veined (especially beneath), broadly 

 cordate-ovate, mostly obscurely 3-lobed towards the top 

 (on strong growths the sinuses sometimes extending a 

 third or even half the depth of the blade, and rounded 

 and edentate at the bottom) or sometimes nearly con- 

 tinuous in outline and almost deltoid-ovate, the petiolar 

 sinus mostly shallow and very open (ranging to narrow 

 and half or more the length of the petiole), the margins 

 shallowly scallop-toothed with mucro-pointed teeth (or 

 sometimes almost entire), and the apex and lobes acute, 

 the upper surface dull green and becoming glabrous 

 but the lower surface densely covered with a tawny- 

 white, dun-colored or red-brown tomentum : stamens 

 long and erect in the sterile fls. and (in wild forms) 

 short and recurved in the fertile ones : raceme short 

 (berries usually less than 20 in wild types), generally
