文章题目泰国绒毛蕨属(荨麻科)三新种--绒毛蕨属E.kaweesakii Triyutth。&L.F.Fu，sp.Nov.、大麦E.rubricaule Triyutth.&L.F.Fu，sp.11月和E.saxatile Triyutth。&L.F.Fu，sp.Nov.，均为新描述和图解。这些新种可以通过根状茎的存在来区分。Elatostemakaweesakii与阿托维里棘球藻相似。Elatostemakaweesakii是生长在石灰岩裂缝中的石生植物。其区别在于根茎膨大，茎无毛，花托无毛，雄花有花被片，雌花无花被片，雌花有退化雄蕊，瘦果光滑。在砂岩生境中发现了两种类型的弹状藻类。它们有明显的扁平和盘状根茎。弹力木的特点是茎明显具槽和带红色，根茎扁平且圆盘状，叶为纸质，边缘全缘。弹力木与球茎相似，但不同之处在于其扁平的盘状根状茎，锐尖的叶尖，雌花花序中无毛的花托，雌花中有退化雄蕊，以及砂岩生境。提供了描述、分布、生态和物候学数据。
Three new species of Elatostema (Urticaceae) from Thailand, E.kaweesakii Triyutth. & L.F.Fu, sp. nov., E.rubricaule Triyutth. & L.F.Fu, sp. nov. and E.saxatile Triyutth. & L.F.Fu, sp. nov., are newly described and illustrated. These new species can be distinguished by the presence of rhizome. Elatostemakaweesakii is similar to E.atroviride. Elatostemakaweesakii is a lithophyte growing in limestone crevices. It differs from E.atroviride by its large swollen rhizome, glabrous stem, glabrous receptacle, number of tepal in staminate flower, absence of tepal in pistillate flower, presence of staminodes in pistillate flower and smooth achene. Elatostemarubricaule and E.saxatile are found on sandstone habitats. They have distinct flattened and disk-like rhizome. Elatostemarubricaule is distinguished by its distinct sulcate and reddish stem with flattened and disc-like rhizome and chartaceous leaves with entire margin. Elatostemasaxatile resembles E.bulbiferum but differs by its flattened and disc-like rhizome, acute leaf apex, glabrous receptacle in pistillate inflorescences, presence of staminodes in pistillate flower, and its sandstone habitat. Descriptions, distribution, ecological and phenological data are provided.
