About plant names...

Sawgrass. What a perfect name! The long straplike leaves are serrated on the sides, and capable of inflicting serious wounds. It forms nearly impenetrable stands, especially in the Florida Everglades. It is technically a sedge, one of a large group of grasslike species, most of which are modest in size. Sawgrass is native to the Caribbean islands and southeastern United States. It prefers limestone soils at the edges of freshwaster and brackish marshes, lakes, streams, and ponds.

Plants: Culms (stems) are 3-9½' (1-3 m) long × ⅛-⅜" (5-10 mm) wide.

Leaves: Alternate, flat or almost flat, like a squished diamond in cross-section, ⅛-⅜" (5-11 mm) wide, with parallel veins.

Flowers: Spikes 12-20" (30-50 cm) in height display 6-9 brownish flower clusters. Flowers appear from July to October.

Fruits: Achenes are light greenish brown and ovoid in shape, about ¹/₁₆" (2 mm) × ¹/₃₂" (1 mm).
