KOSACEAE . — PRUNUS 273 



Western Szech'uan: two miles north of Tachicn-lu, very rare, 

 alt. 2800 m., October 1910 (No. 4205). 



This is the first Peach known with a smooth stone. I have a foUiferous branch 

 of an " Armjgdalus lancifolia Carr." collected in Spilth's Arboretum near Berlin, 

 October 3, 1887, the leaves of which agree exactly with those of P. mira. I have 

 not been able to trace the name Amygdalus lancifolia in literature. There exists 

 only a Prunus lancifolia Clavaud wliich is referred to P. maritima Wangenheim in 

 the Index Kewensis.
