In Hydropyrum, of Prof. Link ; the palez of the male "RM 
are decidedly membranous ; they are of tolerably equal size, 
and muticous, the upper, 3 nerved, the central nerve not so 
strong as the lateral ones, the lower 5 nerved, the central one 
being the strongest. There are six stamina and a very small 
rudiment of a female flower. 
The female flowers are seated on a cartilaginous hard knob,
