在过去的半个世纪里，夏威夷的蕨类植物受到植物学家的关注相对较少。然而，最近在这些岛屿上进行的深入研究发现了许多以前未描述过的物种，包括这里命名的quillwort。自本世纪初以来，夏威夷曾多次发现水螅属植物。 1917 年 9 月 25 日至 10 月 17 日期间，查尔斯·N·福布斯 (Charles N. Forbes) 在毛伊岛埃克山山顶的水池中发现了水韭 (福布斯 682. M. BISH)。福布斯不承认他的收藏是 Isoetes。直到 1977 年 10 月 17 日，当 F. R. Warshauer 从夏威夷大岛莫纳克亚山东坡采集水韭 (Warshauer & McEldowney 1500 BISH) 时，夏威夷植物学家才意识到植物群中存在一种本土的水芹。 1980年10月23日，罗伯特·W·霍布迪（Robert W. Hobdy）再次在埃克山山顶的水池中发现了水韭（Hobdy 931 BISH），并于1982年10月21日在同一地点再次采集到了它（Hobdy 1705-1710 BISH）。对这些标本和后来从埃克山采集的三个标本（Taylor 5332、5658 MIL 和 Palmer 672 BISH）的研究表明，这些夏威夷槲寄生代表了一种以前未描述过的水韭属物种。
The pteridophytes of Hawaii have received relatively little attention from botanists during the past half-century. However, intensive recent studies in the islands have revealed a number of previously undescribed species, including the quillwort named here. Quillworts have been found in Hawaii several times since early this century. Between 25 September and 17 October 1917, Charles N. Forbes discovered Isoetes from pools atop Mt. Eke on the island of Maui (Forbes 682. M. BISH). Forbes did not recognize his collection to be Isoetes. It was not until 17 October 1977, when F. R. Warshauer collected Isoetes from the east slope of Mauna Kea on the island of Hawaii (Warshauer & McEldowney 1500 BISH), that Hawaiian botanists realized there was a native quillwort in the flora. Robert W. Hobdy again discovered Isoetes in pools on the summit of Mt. Eke on 23 October 1980 (Hobdy 931 BISH), and he collected it once more from the same site on 21 October 1982 (Hobdy 1705-1710 BISH). Study of these specimens and three later collections from Mt. Eke (Taylor 5332, 5658 MIL and Palmer 672 BISH) indicates that these Hawaiian quillwort acquisitions represent a previously undescribed species of Isoetes.
