which bore flowers. The sporophylls (cone scales) of these 
flowers are closely arranged spirally on an axis which is at 
this time about 4™™ in length, and are surrounded by scale 
leaves which are borne lower down on the same axis. Each 
tight or ten in number, most numerous on the middle sporo- 
phylls of each flower. The middle sporangium on each sporo- 
Phyll has its axis nearly parallel with, but slightly inclined 
sl (lower or outer) side of the single fibrovascular bundle. 
The abrupt bend between the basal and terminal parts of the 
broad (figs. t and 2), and the integument reaches to a level 
mith the flat top of the sporangium. 
Just as the flowers had closed in F ebruary, Mr. B. M 
Davis Collected a hermaphrodite flower. In this flower the 
‘Pet sporophylls are macrosporangiate and like those of the 
female flowers, and five of the lower sporophylls are micro- 
‘Porangiate (male) and, with the exception of the upper one 
Which is in forin like a female sporophyll, are similar to those 
of the tegular male flowers. The relative positions of the 
Wo kinds of Sporophylls is the same as the relative positions 
Which the two kinds of flowers occupy on the branches of iG 
tee; the female flowers are formed on the terminal shoot an 
"ghboring twigs of each fertile branch, and the male ake 
on the lateral twigs of the same branches. And correspond- 
"gly the lower branches of the tree bear more male than fe-
