 CASE chlcena hypoleuca, Kunze,) used in Chili as a diuretic and 

 expectorant. 



No. 214. Aeuhe the rhizomes of Pteris aquilina^ L. 

 var. esculenta. They were formerly roasted and eaten by the 

 natives of New Zealand. 



No. 215. Brake or Bracken {Pteris aquilina,) Britain,- 

 from the rhizomes of which a farinaceous food has been 

 obtained and used in times of scarcity. Meal prepared 

 from the rhizomes of this fern and used as food in Japan is 

 here shown. Note also Ash Balls made from ashes of the 

 burnt fronds of the Brake, which are collected by the cottagers 

 in Monmouthshire during the summer months and burnt. The 

 ash is then moistened sutficiently to enable it to be moulded 

 into balls, which are afterwards dried, and are ready for use in 

 washing all kinds of clothing. They were formerly sold at 

 from Ss. to 4s. per hundred in the market, but the more general 

 use of soda has reduced the demand for them. The extreme 

 variability of shape in the fronds of many ferns is well 

 illustrated in Pteris quadriaurata, Retz. A mounted specimen 

 is shown.
