The Chinese form differs from the tj'pe in the generally larger and shorter petioled 

 leaves and in the more spreading corolla lobes which give the flowers a star-like 

 shape. Styrax seminatum (1901) Farges, quoted by Miss Perkins (1. c.) as a synonym, 

 is not a name, but signifies sowing No. 1901 collected by Farges; seminatum is 

 the term employed by Vilmorin for all undetermined sowings or seed lots. 



A very distinct variety is the following: 



Styrax japonicus, var. calycothrix Gilg in Bot. Jahrb. XXXIV. Beibl. LXXV. 

 58 (1904). 



Shantung: Lau-shan, August 1907, F. N. Meyer cNo. 277). 



Differs from the type in the densely stellate-pubescent calyx and in the obovate 

 leaves long-acuminate and at the base very gradually narrowed into the petiole. 



Styrax Perkinsiae Rehder, n. sp. 



Frutex 2-3-metralis; ramuli tomentosi purpureo-virides v. ob- 

 scure virides, puberuli et stellato-pilosi, annotini glabrescentes, ut 

 vetustiores griseo-f usci ; gemmae tomento fulvo v. flavescente vestitae.

 denticulata, 4.5-7.5 cm. longa et 2.3-3.7 cm. lata, supra obscure viridia,

1 According to a specimen of No. 422 in the Arnold Arboretum herbarium; the 

 true S. serrulatum Roxburgh does not seem to occur in China at all.
