Quercu.s"Leana, Nutt. — In an article on the "Oaks of the Po- 

 tomac side" which I contributed to Field and F'orcst for October and 

 November, 1865, occurs the following remark: "Two trees which I 

 have recently discovered in a wood near the northwestern (northern) 

 corner of the District of Columbia, have proved unusually interesting. 

 That these should be called Qucrcus Lcana and not Q hetcrophylla I 

 maintain f r the following reasons : Their resemblance to Q_ IicterophxUa 

 as it exists in the herbarium of the Department of Agriculture is not 

 sufficiently close to warrant this name, the leaves being broader and 

 less lobed 'I'hey do agree substantially with the specimens of Q. Leana 

 in that herbarium. They also agree remarkably well with the tree 

 which Mr. W. R. Smith, Superintendent of the U. S Botanical Gar- 

 den lias raised in his grounds from an acorn of Q. imbricaria. Finally, 

 on considering the locality in which these trees were found, it seems im- 

 possible to believe that (), PlicUos can have entered into the combina 

 tion. Li the entire wood where they are situated not an individual of 

 that species exists. It is wholly wanting throughout the region of 

 Rock Creek on which the grove is located. On the contrary the 

 prevailing oak there is Q. imbricaria, although both varieties of Q. coc- 

 cinea are al'io frequent. It cannot therefore be justly claimed that 

 this new discovery constitutes a revival of the famous Bartram's Oak 

 since this was dec-ded on the highest authority to be either a fdrm df 

 Q. Phellos or a union of that species with Q. coccinea var. tinctoria. 

 It is, however, none the less a botanical curiosity." 



Since the above was published I have re-visited the locality no less 

 than five times and have succeeded in obtaining an abundance both 

 of fruiting and flowering s]:)ecimens, of which I may say, en passant, 

 I have a supply for distribution and exchange. My latest visit was
