2. HALESIA, Ellis. Snowdrop or Silter-bell Tree. (Commem-

 rather large, ovate-oblong, acuminate, more or less denticulate, slender-petioled, 

 deciduous ; flowers showy, drooping on slender pedicels, in fascicles (or rarely 

 very short racemes) from the axils of fallen leaves of the preceding year, pro- 

 duced in spring at leafiug-time ; corolla white. Thin testa of the seed adherent 

 to the pericarp ; the delicate inner coat adherent to the albumen. — {Pterustyrax, 

 Sieb. & Zucc, of Japan, referred to this genus by Bentham and Iluoker. although 

 nearly related, is better kept distinct, on account of the terminal paniculate inflo- 

 rescence, quinary flowers, and thinner small fruit.) Ellis ia PhU. Trans, li. t. 22 ;
