| 摘 要： | 本种为我国南方常见一种经济红藻。藻体直立,叶片窄带状,单条或叉状,全缘或有小育枝,体下部淅细成柄状。藻体不中空。我们发现它在生殖器官发育过程中也出现三个新特徵:1、少数果胞枝与助细胞可在同一的生殖枝丛中形成,2、少数果胞枝枝丛中可出现2个果胞枝;3、少数助细胞枝丛中可出现2个助细胞。

| Abstract: | The coastal areas along Quangdong province are rich in resource of Grate- loupia livida. This kind of alga is also found in 1962. Its thalli are erect. They grow on rocks or in rock pools in the lower intertidal zone, They are coriaceous, purplish red or yellowish red, 10-25 cm in height, 1-2.5cm in width and lubrious in substance. The upper part of its thallus is simple or furcate, sometimes once or twice, but its lower part is getting attenuate and_ transforms to be a short stipitate. Its filaments of medulla are interwoven. The development of organs of G. livida is generally the same as that of g. filicina. We have also observed following three new characteristics. 1. Some carpogonial branches and auxiliary cells may appear on the sa- me ampullae. 2. A few carpogonial branch ampullae have two carpogonial branches. 3. A few auxiliary ceil ampullae have two auxiliary cells. |
