2'S. bicolor, Lo t'.mte ( r. anirnfiio/in , JluuS'tn). Blue 

 Okape. or Slmmek Gkape of tlie North. FIlt. 2701. A 

 strong:, hii^h-climbiiii: vine, with mostly long interiHMh's 

 aad thick diaphragms, the young growth and rant's 

 generally perfectly glal>rous and mostly (but not alwiiys) 

 glaucous - lilne. tenilrils 

 and petioles very long: 

 Ivs. large, round-cordate- 

 ovate in onfline. glabrous 

 and dull above and Vrry 

 heavily glaucous - biue

 bloom and becoming dull

 Ranges from New FjU-j;. and 111. to the mountains of 

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

 from r. irsfirdlls (at least in its northern forms) by the 

 absence of rufous tomentum, the bUie-^lau<'ous siuall- 

 toothed leavf^s, an<l lonir pptinlfs and tendrils. It ha^ 

 been misundnrstfiod I'ei-ause it loses its glaucous char- 

 acter in the fall. 



24. Caribeea. DC. Fiir. 2702. Climbing, with floccnlent- 

 woully (or rarely almost glabrous) and striate shoots: 

 tendrils rarely continuous: Ivs. cordate-ovate or even 

 broader ami mostly acuminate-pointed, sometimes ol)- 

 scurely angled above ( Init never lobed except now and 

 then ou yumg shoots), liecoming glabrous aliove but 

 generally renuuning rufous-tomentose below, the mar- 

 gins set with very small, mucro-tipped .sinuate teidh ; 

 cluster long and long-peduncled, generally large and 

 very compound : tierry small and globose, purple : seed 

 obovate, grooved on the dorsal side. Awidely distributed 

 and variable species in the American tropics, ninuing 

 into white-leaved forms (as in T'. Bhi)\raj, I^Iunson).

Var. coriacea, Bailey( C. on-iarra, Sliuttl.). Leather-

 species chiefly in bearing niin-h smaller (about ^i, in. 

 in diam.) thinner-skiTined and more edilde 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 rnstiness on the young 

 growths. Florida, chiefly southward, in which range 

 various Texan plants reappear.— The more agreeable 

 quality of the fr. is proba!)ly the result of a more 

 equable and moister climate.

 much-cut Ivs. on the yonn;^ shoots and comparatively 

 thin, large and large-toothed oiu-s ou the main shoots, 

 rusty - white tomentum below and very prominently

 Ivs. and tomentum varying widely, the foliage some- 

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

 is likely a hybrid of C. a'sfivaJis and F. candicaus, var. 

 coriacea. Some forms of it are very like T'. Lahrusca , 

 and might be mistaken for that species.
