Pieris ovalifolia Hemsley in Jour. Linn. Soc. xxvi. 17 (1889), in part. — Diels

Lyonia ovalifolia Pampanini in Nuov. Giorn. Bot. Ital. n. ser. xvn. 683 (1910);

 Pieris ovalifolia var. elliptica Rehder & Wilson in Sargent, PL Wilson. I. 552 



(1913). 

 Pieris elliptica Nakai in Tokyo Bot. Mag. xxxm. 207 (1919); Trees Shrubs 

 Jap. i. 149, fig. 87 (1922). 



This variety differs chiefly in its thinner leaves and smaller fruits (3-4 

 mm. in diameter) from the type which has coriaceous leaves and larger 

 fruits 4-5 mm. in diameter; none of the other characters given by Siebold 

 & Zuccarini to distinguish the Japanese plant from that of the Hima- 

 layas holds. This variety is widely distributed through China except in 

 the northern provinces and is also common in central and southern Japan. 



Xolisma villosa, comb, no v.

 t Pieris Henryi L6veill6 in Bull. Soc. Bot. France liii. 204 (1906); in Fedde, 



Rep. Spec. Nov. ill. 262 (1906). 



This species is very similar in general appearance and in most of its 

 characters to the preceding species but is easily distinguished by the 

 pubescence on the under side of the leaves, by the shorter inflorescence, 

 by the lanceolate longer calyx-lobes divided nearly to the base and by the 

 absence of the appendages of the filaments. It occurs at altitudes of from 

 3000-4000 m. on the Himalayas from Ghurwal to Sikkim and also in 

 western China as far north as western Szechuan. Judging from the des- 

 cription I have little doubt that L6veill£'s Pieris Henryi belongs here. 



Xolisma villosa var. pubescens, comb. nov. 



Pieris ovalifolia var. pubescens Franchet in Nouv. Arch. Mus. Paris, s6r. 2, 



x. 44 (PL David, n. 82) (1887). 

 Pieris villosa var. pubescens Rehder & Wilson in Sargent, PL Wilson, i. 554 



(1913). 



This variety differs from the type in its pubescent ovary and is known 

 only from western Szechuan. 



Xolisma compta, comb. nov. 



(1916). 



W. W 



Of this species I have not seen the type but a specimen collected in the 

 Yunnan Fu district by O. Schoch (No. 145) and determined as P. compta 

 by Schneider agrees well with the original description except that the 

 calyx-lobes are ovate and obtuse rather than ovate-lanceolate and acutish 

 and the ovary is ovoid and not depressed globose; the longest leaves of 

 Schoch 's specimen are up to 3.5 cm. long and the minute dots of the under 

 side are not black. The general appearance of the plant suggests a species 



alifolia
