GENERA JUGLANS, FRAXINUS, &C. 255 



8. £>uercus rubra ramosissima Marsh, is Ch 

 palustris Wangenh. & Du Roi t. 5. fig. 4. Its 

 leaves are comparatively small, as are the cups of 

 the acorns.* 



9. An Oak very similar to the latter, with regard 

 to its leaves, is that which they call here Black 

 Jack. It never attains any remarkable height, 

 but its wood is considered as very good fuel. As 

 it does not grow in any place nearer to me than 

 the islands of the Susquehanna, I have not as yet 

 been able to ascertain whether it be any more 

 than a mere variety. The wood of No. 8 and 9 

 is not good for fuel. 



10. ^uercus coccinca, the Scarlet Oak, is dis- 

 tinguished from No. 7 and 8 by its leaves turning 

 to a fcarlet-red color before they fall off. The 

 cups of the acorns are not flat at the base, but 



$K ruhra : foliis oblongis sinmtis glabris, lobis divaricatis apicc denta- 

 tis acutis setacco-mucronatis, calycibus fructus basi plauis. 



* The specific character Michaux gives, of it is as follows : 



^palustris: foliis longe petiolatis, profundius 7-lobis sinubus Utis, 

 lobis oblongis, acute subdivisis; fructu parvo; cupula scuteHata Is 

 glande subglobosa.-— Mich. n. 19. pi. 33. 34. T.
