 Gbape, or Summer Gkape of the North. Pig. 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-

24. CaribaBa, DC. Fig. 2702. Climbing, with flocculent- 

 woolly (or rarely almost glabrou-) and striate shoots: 

 tendrils i-arely 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 di.stributed 

 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.

 various Texan plants reappear.-The more agreeable

 equable and moister climate. 



26. Slmpsoni, 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-tomentose 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. (estivalis and I', eandicans, var. 

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

 and might be mistaken for that species.
