one ma>-decide, barring cogent evidence tothe contrary, whether 

 Gronovius meant the mountains or the coast of Virginia, or the 

 mountains and the coast of a nearby State. The scanty value of 

 colonial maps is well illustrated by the proceedings of the meet- 

 ings in which the thirteen original vStates settled their boundaries 

 among themselves and with the Federal Government. 



In conclusion: the presentation of T. americana must be in- 

 terpreted in the absence of a type-specimen. It rests, conse- 

 quently upon textual evidence. Textual uncontroverted evi- 

 dence in Plukenet's polynomial points to a Linden having broad 

 glabrous leaves. This Linden has a northern range, from Vir- 

 ginia to Canada, and the locus classicus, in a narrow sense, is 

 Philadelphia. Only the species that Sargent calls T. glabra (Man. 

 Tr. N. Am. 733-734. 1922) answers this description and this 

 range. It follows that T. americana is valid and rules out the 

 later T. glabra Vent. To this extent the writer fully agrees with 

 Suringar (Meded. Rij. Herb. Leid. 56: 28. 1928), whose under- 

 standing of T. europaea L., and "varieties," will be discussed in 

 a coming article.
