Female Flower of Jug Ians regia and a few allied Genera. 625 
upper portions are free. The bract varies in the degree of adhesion, the 
cupule shows only a free rim and the perianth four free tips surrounding 
the two- or three-lobed styles. Nevertheless the vascular supply for each of 
the leaves is given off from the stem stele at the base of the flower, which, 
as Van Tieghem points out, is erroneously called ‘ an inferior ovary \ These 
leaf bundles are entered in Text-fig. 1 . 1-3, but in the other figures of Juglans , 
Text-figs. I. 4-7, III, and IV, the outer bundles are merely represented 
by a single line, since it is with the gynoecium we are mainly concerned. 
Gynoecium. 
The trimerous condition is relatively rare but interesting as showing 
a resemblance with the gynoecia of the Fagaceae.
