Acacia confusa 台灣相思
The seeds of the Acacia confusa Merr also serve as its leaves, and there are two types of this tree: the first has pinnately compound leaves, while the second has phyllodia, which are flattened leafstalks with parallel veins. The phyllodia for the trees that have them are narrow, somewhat sickle-like, and roughly 6-10cm long and 1cm wide. The legumes of the Acacia confusa Merr are pencil-shaped, and the tree itself has many uses: they can be planted to serve as windbreaks, and their wood is suitable for making both railroad crossties and the support beams used in mining shafts.
