occurs. Afterwards the whole head becomes woody (bracts as well) 

 enclosing the ripening seeds. The seed is winged and is enclosed in 

 the woody bracteoles. The wood (beef- wood) is valued for its hard- 

 ness; several sp. are used, known in Austr. as she-oak, forest-oak, 

 &c. The green shoots are used as fodder for catlle. 



Casuarinaceae (EP., BH.}. Uicots. (Archichl. Verticil.; Unisexuales 

 BH.}. Only genus Casuarina (e/.v.). The place to be assigned to 

 this fam. in the natural Astern has been much disputed. Its nearest 

 allies seem to be Betulaceae. In 1891 Treub discovered the chalazp- 

 gamic fert. (cf. Ckalazogamae) and proposed to remove it from its 

 place near the B. Later discoveries however show that these pi. too 

 are chalazogamic, as also Juglans, and thus C. may still be kept beside 

 them.

 different forms occur on different (or sometimes on the same) stocks. 

 Long regarded as separate gen., it is now known that they are all 

 forms of C. The old genus C. is the g form, Myanthus Lindl. the 

 $ and Monachanthus Lindl. the ? . The label 1 urn is uppermost in 

 the fl. The pollinia are ejected with violence when one of the horns 

 of the column is touched. (Darwin's Orchids, p. 178 ; Rolfe in Linn.
