ROSACEAE. — PRUNUS 273 
Western Szech’uan: two miles north of Tachien-lu, very rare, 
alt. 2800 m., October 1910 (No. 4205). 
This is the first Peach known with a smooth stone. I have a foliiferous branch 
of an “Amygdalus lancifolia Carr." collected in Spüth'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 which is referred to P. maritima Wangenheim in 
the Index Kewensis.
