KLATE III 



Fruiting Branch of a New Disease-Resistant Chinquapin from China. 

 (Castanea seguinii Dode, S. P. I. No. 45949.) 



Three important facts ha\ebeen established in regard to the chestnut bark disease: First, that all 

 species of Castanea are net equally susceptible to the fungus; second, that hybrids between the 

 different species arefertile: and, thhd, that the factor which produces immunity, what ever that is, 

 appears to be heritable and by breeding and selection can be incorporated with other characters 

 such as size and quality of the nut, size of the tree, etc. This Chinese chinquapin, occurring near 

 Ichang, is a shrubby species, occasionally growing to 40 feet in height . Frank N. Meyer, who dis- 

 covered the chestnut bark fungus, Endothia parasitica, in China, report s this species as apparently 

 totally resistant to the disease. It grow s v ell on barren mountain slopes but appears to he more 

 moisture loving than the chestnut, Castanea mollissima. Introduced primarily for breeding pur- 

 poses. (Photographed by Frank N. Meyer, Tzewuhsien, Sherisi, China, September 1. 1014:
