Cotoneaster Dielsiana, var, elegans Rehder & Wilson, n. var. 



A typo praecipue recedit foliis minoribus, saepe obtusiusculis v. 

 obtusis, subpersistentibus quamquam tenuioribus, fructibus minori- 

 bus, miniatis pendulis. Frutex 1-2-metralis, erectus, ramis gracilibus, 

 divaricatis arcuatis. Folia ovata v. ovalia, 1-2 cm. longa et 6-13 mm.

 subtus cinereo-tomentosa. Fructus globosus, pendulus, corallinus, 5-6 

 mm. diam., pedicellis 1-2 mm. longis; pyrenae 2-5 triangulari-oblongo- 

 obovoideae, 3.5-4.5 mm. longae et 2-3.5 mm. diam., ventre carinatae, 

 nitidae, stylum trientum infra apicem gerentes, dorso pallidae, ir- 

 regulariter foveolato-rugosae, hypostylio dorsi trientem v. ultra

Western Szech'uan: Tachien-lu, alt. 2600-3000 m., thickets, 

 July and October 1908 (No. 1287, type); Wa-shan, alt. 2300-2600 m., 

 cliffs, June and September 1908 (No. 2170, bush 1-2 m.tall, flowers pink, 

 fruit coral red). 



This western plant shows marked diflFerence from the type and in several respects 

 approaches Cotoneaster Franchetii Bois. It also has affinity with Cotoneaster 

 Zabelii Schneider. Its thinner yet more persistent leaves, smaller pendulous fruit, 

 brick or orange-red, distinguish this variety from the typical form.
