Atago Mountain Plants-Tree 3 (Ki-ko)
ススキ
Chestnut. Beech family Chestnut. It is dioecious and blooms from May to June. From September to October, a few fruits are borne in acorns with squid. It seems that there are two or three chestnut trees from the falling squid, but so far it has not been possible to identify which tree.
ススキの花穂の葯
黄色いつぶつぶに見えるのが雄しべで、その細長い先端部は葯（やく）と言われ、中に花粉が詰まっている。葯は開花の始めに見られるが、やがて白色の綿毛が伸びて穂全体が白っぽく見えるようになる。
