This passage describes a dicot aquatic plant commonly referred to as “Nesaea sp. ‘Golden,'” which is a type of submerged aquatic plant with attractive golden-yellow colors. At times, it bears some resemblance to Nesaea gracilis (also known as Golden Nesaea). Initially, due to uncertainty about its exact species, it was described using the old scientific name Nesaea sp. “golden.” However, it was later identified as a variant of African Nesaea (Nesaea pedicellata).

The emergent form of the plant has cross-opposite narrow ovate leaves ranging from yellow-green to yellow-orange in color, with a relatively firm texture. The stems are a vibrant red. The submerged form displays different characteristics, including narrower lanceolate leaves that are quite soft, exhibiting colors ranging from yellow-green to pink and golden-yellow. The stems maintain their striking red hue, contributing to its overall beauty. This plant has a slow growth rate and requires a bit of care in cultivation.

When lacking calcium, the upper leaves are prone to curling. The use of root fertilizers proves effective. CO2 supplementation is necessary, and insufficient light can lead to the onset of melting leaves. Regular water changes significantly enhance its photosynthesis and contribute to improved cultivation quality.

雙子葉植物,挺水性水草。這種可能呈現美麗的金黃色水草,有時與黃金柳(Nesaea gracilis)有些相似,發現初期因無法確定其種,故以舊學名 Nesaea sp. “golden”來描述,後來確定它是非洲紅柳(Nesaea pedicellata)的變異種。水上草具有黃綠至黃橙色的十字對生狹卵形葉,葉質較硬,莖為鮮紅色;水中草則展現不同的型態,包括葉片轉為狹披針形,而且相當柔軟,以及可呈黃綠、粉紅至金黃色,莖依然保持鮮紅色,相當漂亮。生長速度緩慢,栽培稍有難度。缺鈣時,頂葉易發生捲曲症狀。埋設根肥相當有效。必須添加二氧化碳。光線不足時,容易產生溶葉症。多換水可以明顯促進它的光合作用,而且有助於栽培品質的提升。
