though well-developed, except that no embryo-sac appears. The her- 
maphrodite cones and their flowers accord in many respects strikingly 
with the male cones of Hphedra ; but the anthers are trilocular, which is 
remarkable. The simple ellipsoidal pollen is the same in both. In 
Ephedra the stamens vary from two to eight, and the column is solid, 
there being no rudiment of a gynzcium. 
The female fruitful cones are about three inches long, and bright red

The integument of the ovule, as in @netum, is prolonged at the summit 
into a style-like body, thus closely simulating a pistil; and the apex of 
this styliform tube, which is thin and merely erose in the fertile flower, 
in the structurally hermaphrodite flower is dilated into a broad papillose 
disk, exactly imitating a highly developed stigma—a marked instance 
of a highly developed organ which is functionless; for no pollen has.
