OBSERVE the 2 accrescent (enlarging after flowering) 

 bracteoles, apparently replacing the perianth in the pistil- 

 late flowers of Orache (Atriplex) : the stamens opposite 

 to the segments of the perianth in the type.

Several species are cultivated, as Mangold Wurzel and 

 Beet, both varieties of Beta vulgaris, an herb growing 

 wild on our shores. In France and Central Europe Beet 

 is extensively cultivated for the sake of the sugar con- 

 tained in the saccharine juice of the root. One ton of 

 Beet-root is reckoned to afford 100 Ibs. of raw, or 55 Ibs, 

 of refined sugar. 



Garden Spinach is Spinacia oleracea. Wild Good- 

 King-Henry (ChenopocUum bonus- Henricus) and Garden 

 Orache (A triplex hortensis] are also used as pot-herbs. 



* When there is no indication in the fully-grown pistil of 

 the number of carpels which compose it, its apocarpous or 

 syncarpous nature can be ascertained only by a study of its 

 development.
