beneath. In No. 415a the leaves are longer, generally ovate- 

 oblong, the pedicels very long and slender, about 3-4 cm. long and 

 the sepals are mostly long-acuminate. The fruit of No. 556a is rather 

 large, about 1-1.4 cm. in diameter, but a fruit examined proved to be 

 2-celled. 2 



This species was introduced by E. H. Wilson to the Arnold Arbore- 

 tum in 1908 and the young plants seem to be hardy here. 



The following Japanese pear is referred by Koidzumi as a variety 

 to P. Cattery ana. 



Pyrus Calleryana var. dimorphophylla Koidzumi in Jour. 

 Coll. Sci. Tokyo, XXXIV. art. 2, 56 (1913). 



Pyrus Calleryana Maximowicz in Bull. Acad. Sci. St. Petersb. XIX. 172 



(1873); in Mel. Biol. IX. 169 (1873), quoad plantam japonicam. 

 Pyrus dimorphophylla Makino in Tokyo Bot. Mag. XXII. 65 (1908). 



Japan: Prov. Ise and prov. Shinano (ex Makino and Koidzumi). 2 



10. Pyrus kolupana Schneider, III. Handb. Laubholzk. I. 665 

 (1906); in Fedde, Rep. Nov. Spec. Ill, 120 (1807). 



Shensi: Ko-lu-pa, G. Giraldi (Nos. 1050, 5105, ex Schneider). 

 This species is little known and not yet in cultivation. 



11. Pyrus Koehnei, Schneider, III. Handb. Laubholzk. I. 665, fig. 

 363 m, 364 t-u (1906); in Fedde, Rep. Nov. Spec. III. 119 (1907).— 

 Koidzumi in Jour. Coll. Sci. Tokyo, XXXIV. art. 2, 57 (1913). 



Pyrus Kawakamii Hayata in Jour. Coll. Sci. Tokyo, XXX. art. 1, 99 (1911). 



Chekiang: Tien-tai mountains, alt. 1000 m., E. Faber (ex 

 (Schneider). Formosa: Nanto, T. Kawakami (ex Hayata). 



This species like the preceding is as yet little known and is not in 

 cultivation. As I have seen neither a specimen from the type local- 

 ity nor from Formosa, I do not know whether Koidzumi is right in 

 referring P. Kaioakamii as a synonym to P. Koehnei.

2 A closely related species, P. Fauriei Schneider (III. Handb. Laubholzk. I. 

 666, fig. 363 d.' 1906) occurs in Korea; it differs chiefly in its much smaller 

 leaves and fruits.
