桂皮蕨(Cinnamon fern)

肉桂蕨原产于美洲和东亚，生长在沼泽、沼泽和潮湿林地等湿地栖息地。这种植物需要大量的水，并在潮湿地区生长——我们的照片拍摄于圣玛丽河附近，圣玛丽河是加拿大新斯科舍省最长的河流之一。肉桂蕨类植物产生两种不同类型的复叶。肥沃的复叶生长在植物的中心。它们较短，第一次出现在春天，开始时呈鲜绿色，然后变成肉桂棕色，因此得名。它们被更大、绿色、无菌的复叶所包围。

The cinnamon fern is native to the Americas and eastern Asia, found in wetland habitats such as swamps, bogs and damp woodlands. This plant needs plenty of water and thrives in moist areas – our image was taken near St. Mary's River, one of longest rivers in the Canadian province of Nova Scotia. Cinnamon ferns produce two different types of fronds. The fertile fronds grow at the centre of the plant. They are shorter and first appear in spring, starting out as bright green before turning a cinnamon brown colour, which gives the plant its name. They are surrounded by larger, green, sterile fronds.
