荸薺屬 eleocharis

上個月到濕地公園,在濕地探索中心看到這可愛的水生植物。有如外星異物,也像特色珠寶。

花了不少時間查究,只肯定牠是荸薺屬,品種有點像 eleocharis parvula。

these spikesedge look fascinating, almost like from the outer-space. i met them at the wetland park last month.

spent some time checking out what species they are and couldn’t be sure. the only certain fact is that they are from the genus of eleocharis.

荸薺屬是淡水簇生草本的植物,莎草科。

Eleocharis1

按《醫學百科》,荸薺屬的莖無節,無葉或僅有葉鞘;小穗單生於莖頂;鱗片螺旋排列;下位毛狀體5-8條;花柱基部擴大,於果頂收縮成節,宿存,柱頭2-3;堅果倒卵形,平凸狀或三棱形。我們熟悉的馬蹄(荸薺E. dulcis)正是此屬。

eleocharis is a genus of flowering plants in the sedge family, cyperaceae. water chestnut is one big representative.

eleocharis are known commonly as spikerushes, or more technically as spikesedges. their habitat is generally at wetland or aquatic. they are easily recognizable as they have photosynthetic stems and lack leaves (the leaves have been reduced to sheaths surrounding the base of the stems). wiki
