          I had described as Q. texana.


 Now Engelmann admits 
 that the [crossed out: ab] preceding names
 as given by him were mistakes.
 May he not have
 made others? I think he
 [crossed out: has] has & refer you to one
 example that of Quercus undulata
 & its varieties as given
 in the Botany of the Wheeler 
 Survey & elsewhere.


 I sent you specimens of
 Quercus Durandii & some forms
 of it like those of Q. San Sabea
 for [added: your] comparision with those
 Q. alba var. Gunnisonii in the 
 Torrey herbarium. From Watson,
 description of it in the Botany 
 of 40th parallel I think 
 it may the San Sabea form
 of our Texas oak.
