OF NORTH A BflK RICA. 97 



few botanists can distinguish from canadense, 

 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 

 different from the last ! nearer to T, canadense, 

 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 Euhrjytus, but this happens 

 also in others. My T. riparium or Canadense 

 has ovate leaves rounded at base, tomentose 

 white beneath, shorter petiols &c. 



987. Teuorium bracteosum R. nearly smooth 

 stem grooved, angles obtuse, leaves on short pe- 

 tiols, lanceolate unequaly serrate, acuminate; 

 raceme foliose, flowers axillary to leaves and 

 long bracts laciniate, upper entii'e, 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,
