During my last trip to Cheesequake State Park, I noticed that in the area closest to the entrance of the walkway to the Crabbing Bridge, there were quite a lot of dried up small seedheads poking out from the grass.
Not knowing what they were I used my macro to take a few photos of the seedheads (amazingly enough, the macro could focus on faraway and smaller items).
When I got home, I was delighted to find out that the grass was another of the common species inhabiting salt marshes. Distichlis spicata is a small-sized perennial that is extremely salt tolerant, and can expand via both stolons and rhizomes. It tends to be found in the high marsh, and the interesting thing about the species is that it is dioecious, with male and female flowers residing on separate plants.
Although such an arrangement is common in animals, in sessile plants this might mean that population growth in the species is slower because the plants cannot self-pollinate. There is also 50% less pollen in the population, and the direction of travel of pollen makes a difference. If pollen goes from one male plant to another male, then it is wasted, although this can be somewhat negated by using vectors such as insect pollinators that can be pushed in one direction.
