 B. Lvs. simple, cissus-like. 



1. antarctica, Benth. (Ctssus antarctica, Vent. 

 Vitis Baudinidna, F. Muell. Cissus Baudinidna, 

 Brouss.). Vigorous tall woody climber, the young 

 growths red-hairy or sometimes glabrous: Ivs. ovate to 

 oblong, on hairy petioles, toothed, glandular in the 

 axils of veins beneath : fls. greenish, tomentose, in 

 short cymes, the petals 4 and falling separately: berry 

 globular. Australia. B.M. 2488. Offered in southern 

 California and said to be suitable for covering rocks 

 and walls. 



BB. Lrs. simple, often lobed, vitis-like. 



2. Coignetiae, Pulliat. Very strong-growing vine, cov- 

 ering trees and arbors with a thatch of heavy showy 

 foliage: branches floccose-tomentose when young: ten- 

 drils intermittent: Ivs. cordate - orbicular, with 3-5 

 lobe -like points, the margins shallowly apiculate- 

 toothed, dull above, thickly gray-pubescent beneath: 

 thyrse stalked, short: fr. globular, about % in. indiam., 

 practically inedible, although said to be eaten after 

 being frozen by the Japanese. N.Japan. Gn. 49, p. 48; 

 50, p. 449. R.H. 1898, p. 426-28. -One of the best of all 

 strong-growing vines, and hardy in the northern states. 

 Its foliage becomes brilliant scarlet in the fall, whence 

 it has been called the "Crimson Glory Vine." In gen- 

 eral appearance it much resembles Vitis Labriisca. I 

 is not yet well known. It grows readily from imported 

 tee As. It can also be propagated by layering and by 

 grafting on other stocks. Named for, Mme. Coignet, 

 of Lyons, France. 



BBB. Lvs. icith 3-o leaflets. 



3. hypoglauca, F. Muell. (Cissus hypoglauca, Gray). 

 Foliage handsome and persistent, dark green above and 

 glaucous beneath; leaflets usually 5, obovate to elliptic, 

 acuminate, stalked, entire or toothed towards the apex: 

 fls. yellowish : fr. rather small and nearly globular. 

 Australia. Offered in S. Calif.

 ing cylindrical or club shaped tul.i-rs at tin ir 

 which fall and produce new plants: tall, rliinl.ii

 of a thickened calyx and 4 minute petals. Brazil.

2696. Vitis rotundifolia. the Muscadine grape of 

 the South (X X). 



AA. Species grown primarily for their pomologieal 

 (fruit) interest, all native except No. t8. 



B. Skin of the mature berry usually separating freely 



from the pulp (Nos. 5-27). 



C. Bark bearing prominent lenticels, never shredding: 



nodes without diaphragms: tendrils simple: 

 flower-clusters small and not much elongated: 

 .11- i'ils oral or oblong, without a distinct stipe-like 

 beak. (Muscadlnia.)

 Fox GRAPE, BULLACE or BULLIT or BCLL GRAPE. Fig. 

 2696. Vine with hard, warty wood, running rampantly 

 even 60 to 100 ft. over bushes and trees, and in the 

 shade often sending down dichotomous aerial roots: Ivs. 

 rather small to medium (2 to 6 in. long), dense in tex- 

 ture and glabrous both sides (sometimes pubescent 

 along the veins beneath), cordate-ovate and not lobed, 

 mostly with a prominent and sometimes an acuminate 

 point (but somewhat contracted above the termination 

 of the two 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 leaf-blade: 

 tendrils (or flower-clusters) discontinnou-. every third 

 node being bare: fruit-bearing clusters smaller than the 

 sterile ones, and ripening from 3 to 20 grapes in a 

 nearly globular bunch : berries falling from the clusters 

 when ripe, spherical or nearly so and large ( V,-\ in. in 

 diameter), with very thick and tough skin and a tough 

 muskv flesh, dull purple in color without UOOOH (in the 

 Scuppernong variety silver}' amber- green ), ripe I 

 summer and early autumn: seeds M-% in. long, shaped 

 something like a coffee I.erry. Hiver bank*. "WMiipii, 

 and rieh woodlands and thicket*. S. Delaware to N. Ha. 

 and ^est to Kans. and Texas.
