empt)" ca\ity underneath, separated by a firm partition from the central portion, 

 which contains the scanty albumen and forming embryo. The leaves are 2 to 4 

 lines long, with a tapering base, dilated at the insertion ; on many of the branches 

 they are reduced to this base, the lamina being abortive. The narrow, strap-shaped 

 petals are nearly 3 lines in length, about thrice the length of the very obtuse and 

 slightly scarious-margined lobes of the calyx ; they are inserted by a narrow base.
