Pirus Uyematsuana Makino. = P. dimorphophylla 

 Makino x P. sinensis Lindl. 



A small tree ; trunk erect, attaining about 6m. in height ; 

 branches terete, glabrous, umber-brown but nigrecsent when 

 dried, dispersed with pale lenticels, densely foliose. Leaves 

 deciduous, long-petiolate, alternate, but fasciculate on the 

 ' kurztrieb,' ovato-oval, elliptical-ovate, or ovato-oblong, rarelj- 

 ovato-lanceolate, attenuately long-acuminate, rounded or 

 rounded-subcordate, incurvato-serrate with mucronato-ovato- 

 deltoid teeth, glabrous on both surfaces, chartaceous, brownish 

 or darkish-brown (not black) when dried, about 3i-12cm. long, 

 2|-6cm. broad ; midrib slender, prominent beneath ; veins 

 delicate, not conspicuous, 6-11 on each side, erect-patent, 

 somewhat arcuate upwards ; veinlets densely anastomosing 

 between the main veinlets ; petiole slender, terete, narrowlv 

 canaliculate in front, slightly enlarged at the base, 2-6|cm. long. 

 Flower several, corymboso-umbellate, about 3cm. across, white ; 

 pedicel thinly pubescent. Cah'x-segments deltoid, acuminate, 

 ciliated. Anther deep-purple. Stj'les 3-5. Pome solitary 

 (in my specimens), globose, about 2cm. in diameter, minuteh' 

 and numerously variolate, rounded at the base, slightly 

 umbilicate and naked from the free portion of the calyx-tube ;

This is very likely a hybrid between Pirus sinensis Lindlej' 

 and P. dimorphophylla Makino, having a serration as that of 

 P. communis Linn., from w^hich the serration of P. sinensis 

 Lindl. is very different. I have seen this plant in the above- 



cited locality, where P. dimorphophylla Makino are abundantly 

 growing. Pirus sinensis is commonly found in cultivation in 

 this country.
