The flowers of the grass are grouped together, forming long, airy clusters along a stem that rises above the leaves to a length of about 18 inches (460 mm) and width of 10 inches (250 mm). [ 3 ] Flowers of M. capillaris are perfect with each having about two or three stamens and anthers that are about 1–1.8 mm long.

Seeds begin to develop in about 2–4 weeks if fertilization occurred. [7] Female turtle grass fruits develop into green capsule about 20–25 mm in diameter and can include 1-6 small seeds. [17] [13] After about 8 weeks of growth, the fruit undergoes dehiscence (botany), which releases neutrally buoyant seeds into the water column.
Dianthus armeria is a species of open and periodically disturbed sites. It is normally an annual but can be biennial or a short-lived perennial. New leaf rosettes form at the base of old plants from buds located on their roots, demonstrating that this species is in fact a short-lived perennial and has a life-span of less than two and a half years.

Their larvae develop into B. rufimanus larvae and adults emerge from the seed, leaving a small emergence hole in the seed (smaller than for B. rufimanus). Generalist predators on faba bean leaves such as spiders might feed on B. rufimanus eggs and contribute to their biological control although no data was found on their potential impact on the ...
