356 WILSON EXPEDITION TO CHINA 



flowers (see key, p. 358). On Wilson's No. 4625 the young fruits show only two 

 enlarged sepals, and they differ from the ripe fruits of Henry's No. 10715*^ only in 

 the size and shape of the smaller three sepals, which are longer-pointed and about 

 twice as long as the unripe fruit. Of the ripe fruits I add the following de- 

 scription :

 obovato-oblongi, circiter 1-1.2 cm. longi et 0.8 cm. crassi, apice flavo-pilosi, stylo

 cm. lata, basi paulo contracta, apice rotundata, utrinque sparse puberula, nervis 5 

 distinctis parallehs longitudinahter percursa, 3 (interiora?) fructu subaequilonga 

 apice subito in acumen brevem pilosum contracta; subdenticulata; semen 1, flavo-

 3-4 mm. crassum.
