GENERA JUGLANS, FRAXINUS, &C. 259 



the specific name of ilicifolia be very characteristic, 

 I leave to the decision of other botanifls* ; (^ nana 

 is the old name. It bears fruit in abundance, as 

 aoes also the variety No. 3. Both of them would 

 deserve to be cultivated, but for their roots spread- 

 ing so very far, and impoverishing the soil. 



Perhaps it may be worth the attention of the 

 botanist to know what colours the leaves of diffe- 

 rent oaks assume before they fall off. The follow- 

 ing are my observations on some of them : 



Q. alba of a brownish red (cottony at the 

 flowering time). 

 Castanea yellowish. 

 Prinus brownish red. 

 (^ rubra max, yellowish (cottony at the time 

 of flowering). 

 rubra cocc. scarlet-red. - 

 rubra 1 1 . yellowish. 



nigra 12. brown, brownish red, and fome- 

 times yellow. 



* In my opinion ihc specific name of Ilicifolia of Wangenheim is very 

 proper. I have described this species in my Berliner Baum Zucbt.p. 275.
