294 GARRY ALES. [Diclinous Exogens. 



Alliance XXII. GARBYALES. — The Garryal Alliance. 



Diagnosis, — Diclinous Exogens, with monochla/mydeous, sometimes amentaceous, flowers, an 

 ■inferior fruit, and a minute embryo lying in a large quantity of albumen. 



If we consider this Alliance conterminous with the Qucrnal on the one hand, because 

 of the approach by Garrya to Juglans, so on the other must it stand in near relation to 

 the Euphorbial, in consequence of including Helwingia, which may be considered as 

 being almost a Spurgewort with an inferior ovary. It appears however to be sufficiently 

 limited by its minute embryo, copious albumen, inferior ovary, and diclinous flowers. 

 The former of these circumstances brings it near the Menispermal Alliance, in which 

 alone among Diclinous Orders does this peculiar embryo occur. 



Helwingia has a lateral relation to Sandalworts (Santalacese), in the Epigynous Sub- 

 class
