OF NORTH AMERICA. 97 



few botanists can distinguish from canadensc, 

 and as both names neither apply nor convey 

 any meaning, I propose to abohsh them, and 

 give 7 good names instead for the sp. therein 

 blended: they all are realy of this G. and have 

 similar racemose habit. This has a yellow ra- 

 mose stem sesquipedal, leaves 2 or 3 inches long 

 spikes 3 to 6 inches long, flowers incarnate as in 

 nearly all. Chiefly in Western States. 



986. Teucrium petiolaris R. puberulent, 

 stem with 4 grooves and obtuse angles, leaves 

 on long petiols ovate acute, equaly serrate, base 

 acute entire ; raceme pedunculate terete dense 

 tomentose, bracts acuminate equal to calix, the 

 lower ovate, calix canescent not angular — how 

 difl^erent from the last ! nearer to T. canadensc^ 

 pedal, leaves biuncial not tomentose nor white 

 beneath, raceme quite separated from the leaves 

 and compact. In New Jersey, Long Id. and 

 Virginia, often on the sea shore and with radi- 

 cal surculi as in Eiihemiis, but this happens 

 also in others. My T, riparmm or Qajiadense 

 has ovate leaves rounded at base, tomentose 

 white beneath, shorter petiols &c. 



987. Teucrium bracteosum R. nearly smooth 

 stem grooved, angles obtuse, leaves on short pe- 

 tiols, lanceolate unequaly serrate, acuminate ; 

 raceme foliosc, flowers axillary tt) leaves and 

 long bracts laciniate, upper entire, calix smooth 

 not angular-— another very distinct sp. pedal, 

 leaves 1 or 2 inches long, with flowers at the 

 axils, pubescent beneath. In N. Jersey, Penn- 

 sylvania, Virginia, the T. virginicum of some 

 botanists. 



988. Teucrium lanceolatum Raf. and Col- 

 lins, stem simple pubescent grooved, angles acute 

 at both ends, subequaly serrate, nearly smooth,
