INTEODUOTOKT. 15 



Some of the bunches contained more perfect berries than 

 the one from which this engraving was made, and others 

 with not more than two or three perfect ones. The small 

 undeveloped berries are those that were not fertilized. 

 Other varieties of this class show the same phenomenon, 

 and all that I have examined exhibit more or less the de- 

 formed stamens as shown in Fig. 3. The Taylor and 

 Oporto are both pure native varieties and nearly related, 

 and belong to what appears to be a distinct species, found 

 growing along the Alleghany range, from southern Kew 

 York to Alabama, and along the banks of those streams 

 that flow from these mountains. It probably is also found 

 near the Rocky Mountains, as sevei'al varieties lately re- 

 ceived from Nebraska and Kansas appear to belong to the 

 same species. 



Some of the individuals of this group possess excellent 

 ijualities, which, when properly developed, and their defects 

 remedied, will make the most valuable wine grapes of the 

 coontiy.
