Abstract

The new species Eriolaenabacgiangensis from Vietnam is described and illustrated. The identified key was constructed to indicate the differences amongst three allied species of Eriolaena. E.bacgiangensis was compared with similar species, E.candollei and E.wallichii. E.bacgiangensis differs from E.candollei by the length of pedicel (1.4-2.3 cm long vs. 3.0-4.0 cm in E.candollei); presence of epicalyx after flowers at anthesis in E.bacgiangensis (vs. absence of epicalyx after flowers at anthesis in E.candollei); densely fringed epicalyx in E.bacgiangensis (vs. sparsely fringed epicalyx in E.candollei); style significantly exceeds staminal tube length in E.bacgiangensis, while the style is slightly longer than the staminal tube in E.candollei; the fruit apex round in E.bacgiangensis (vs. pointed and beaked in E.candollei). The linear epicalyx lobes are a key diagnostic trait for distinguishing E.bacgiangensis from E.wallichii (linear vs. ovate in E.wallichii). In addition, the other different characteristics of the two species are: leaf blade (not thickly papery in E.bacgiangensis vs. thickly papery in E.wallichii); length of inflorescences (13.0-18.0 cm in E.bacgiangensis vs. ≤ 6.0 cm in E.wallichii); shape of flower bud (lanceolate in E.bacgiangensis vs. globular in E.wallichii); fruit apex (round in E.bacgiangensis vs. apex shortly beaked in E.wallichii).

Eriolaenabacgiangensis（锦葵科），越南一新种。

记述了越南新种Eriolaenabacgiangensis。构建了鉴定键，以表明三种亲缘种间的差异。并与相似种E.candollei和E.wallichii进行了比较。蒲公英与蒲公英在花梗长度上存在差异（蒲公英为1.4 ~ 2.3 cm，蒲公英为3.0 ~ 4.0 cm）；bacgiangensis花开花后有副萼（而candollei花开花后没有副萼）；bacgiangensis有密边的副萼（相对于candollei有疏边的副萼）；花柱长度明显大于雄蕊管，而花柱长度略大于雄蕊管；果实先端圆圆的在巴吉甘松中（相对于尖的和具喙的在candollei）。线性的外萼裂片是区分巴吉冈e.b和瓦利奇e.b的一个关键诊断特征（瓦利奇e.c是线性的，而瓦利奇e.c是卵形的）。此外，两种植物的其他不同特征还包括：叶片不厚（bacgiangensis与e.o wallichii不厚）；花序长度（巴氏叶青13.0 ~ 18.0 cm，华氏叶青≤6.0 cm）；花蕾的形状（龙井草为披针形，龙井草为球状）；果先端（圆的在巴吉安吉兰对的先端短喙的在华立吉兰）。
