not yet been published. It was, however, communicated to Dr. 

 Engelmann, along with a portion of his specimens, at least five 

 years ago. The conclusion drawn was the following : The husk, 

 or so-called exocarp, of Garya, is an involucre^ usually containing 

 a single female flower, and connate with its ovary ; its ti'ue mor- 

 phology is revealed when, as in this case, it contains two or three 

 flowers. The stone or shell of the nut is the whole pericarp in 

 Garya as much as in Gorylus. In the former genus it becomes 

 free from the four-valved involucre at maturity ; in Juglans the 

 congenital union is more permanent, forming a drupaceous acces- 

 sory fruit, of which the fleshy part is involucre, the bony part is 

 pericarp. This view directly homologizes the Juglandaceae with 

 the Gupuliferse.
