last season and prove very remarkable plants, one from its near alliance with Portu-

from the nearly allied P. oleracea by the broader retuse leaves, i broader calyx; 
by the larger, more distinctly tuberculated, somewhat paler seeds, much larger 
style, and shorter and fewer stigmata. Number of stamina variable. In large speci-
