Two kind species of Gracilaria that grow on the coast of southern Japan, from Kyushu to Tokyo, is described new members of Japanese Gracilaria. Gracilaroa lemaneiformis are called "Seiyo-ogonori as Japanese name. This taxon is similar to G. chorda in morphrogy but has smaller tetrasporangia and larger meduallary cells Plants is solitary, delicate, cylindrical throughout, 30-200 cm. The results of DNA analysis among several materials of different coasts were showed the bands of same pattern of G. lemaneiformis. These plants grow on sandy bottom through the year. The quality of agar contents is higher level in the agarophyte in Japan.Gracilaria coronopiforia were found on the Jogashima, Kanagawa and are called "Yore- ogontri as Japanese name. The pants were cultured in the ponds and tanks in several places, but this species did not expand on any coasts in Japan. Plants are short, 5-30 cm, irregular and subdichotomus, branching to form an entangled mass : purplish color. This species are more two kind morphological types. One is Hawaii type ; longer plants, and another type is south Asian type, smaller plants. DNA analysis of the materials between two kind type are showed different bands.

日本江蓠的新成员描述了生长在日本南部海岸（从九州到东京）的两种江蓠。 Gracilaroa lemaneiformis 日文名称为“Seiyo-ogonori”。该类群在形态上与 G. corda 相似，但四孢子囊较小，髓细胞较大。植株单生，纤弱，通体圆柱形，长 30-200 cm。DNA 分析结果不同海岸的几种材料都显示出相同模式的龙须草，这些植物全年生长在沙质底部。琼脂含量的质量在日本的沉香植物中处于较高水平。江蓠产于神奈川县城岛，日文名称为“Yore-ogontri”。这种裤子在多个地方的池塘和水箱中养殖，但该物种并未在日本的任何海岸扩张。植物较短，5-30厘米，不规则，近二分枝，分枝形成纠缠的团块：略带紫色。本种多有两种形态类型。一种是夏威夷型；植物较长，另一种是南亚类型，植物较小。两种类型材料的DNA分析显示出不同的条带。
