柏の葉第2水辺公園のヒメガマ, Typha domingensis Presl in Kashiwanoha 2nd Waterside Park
柏の葉第2水辺公園の遊水池周辺に少数のガマが生えている。ガマが上部に雄花穂、下部に雌花穂をつけている。雌花序と雄花序が約1 cmほど離れて花茎の軸が見えるので、これはヒメガマだ。
A small number of cattails are growing around the reservoir in Kashiwanoha 2nd Waterside Park. Cattails have male spikes on the top and female spikes on the bottom. The female and male inflorescences are separated by about 1 cm and the axis of the flower stalk can be seen, so this is a Typha domingensis Presl.
