History, Nomenclature and Habitat: The H. kikutii complex is widespread and shows distinct local phenotypes. Among these are distinct forms with larger leaves having more principal vein pairs than those of H. kikutii var. kikutii forma typica. In addition, the principal veins are spaced distinctly closer. This has given rise to the Japanese name Sudare Gibōshi, derived from the Japanese Kanji 簾, which transliterates to sudare (the name for a familiar Japanese rattan blind, a bamboo blind or screen with closely spaced slats). Thus, the Japanese name translates to “rattan blind hosta.” This varietas is well known in Japan and has been cultivated there for many years under its Japanese name スダレギボウシ = 簾擬宝珠 = Sudare Gibōshi. The scientific species epithet is of Greek extraction, poly meaning many, and neuron standing for veins (nerves), hence the meaning “many-veined.”

Notes on Habitat: The species H. kikutii var. polyneuron and H. kikutii var. caput-avis occupy a habitat on the Pacific side of Japan refer

国) are also included here. (1980) investigated the taxonomic and phytogeographic nature of plants considered rheophytes (rheophyte = a plant that is associated with flowing water). Although the mainland of Japan is located in the warm temperate zone, H. kikutii var. polyneuron and H. kikutii var. caput-avis are by Murata, et. al., considered to occupy habitats similar to those of tropical plants, which grow on rocky shelves near rivers in the bottoms of gorges which are either inundated once to several times a year or receive abnormally high precipitation, which results in heavy run-off. The study further states that these rheophytic hostas have evolved to develop tenacious rhizomes and roots that sprout immediately after a flood and which cling to the crevices of rocks anchoring its slender or down-sloping leaves against rushing water. These plants are resistant to physical damage but grow weakly in shade and for this reason H. kikutii var. polyneuron and H. kikutii var. caput-avis are most frequently found in open valleys or ravines with considerable sun exposure. My own observations indicate that these specific and sometimes unique requirements have led to disjunct, small populations that have undergone longtime adaptation to ecological niches, leading to considerable differentiation and polymorphism. Leaning scapes and slender leaves are an expression of this adaptation. On the other hand, the development of larger leaves to maximise photosynthesis has also been observed and this is the case with H. kikutii

Plant Morphology: Note: The description below is average for this varietas. H. kikutii var. polyneuron is a polymorphic taxon, which shows considerable macro-morphological differences in its natural populations. Variants have lanceolate to ovate lanceolate leaves with 9-11 (13) pairs of principal veins, which have a narrow spacing. Although other variants of H. kikutii have leaves with relatively tight vein spacing, this varietas has its veins spaced closer than most other Hosta species. The leaf margins can be straight or undulate. In most individuals, the flower morphology is very uniform and matches that of H. kikutii var. kikutii forma typica. In most populations, the scapes are straight but lean considerably and may reach sub-horizontal position, particularly when growing on vertical rock faces. Plant size 60 cm dia., 25 cm high (24 by 12 in.). Petiole 13 by 0.4 cm (5.2 by 0.15 in. wide) ascending in an arch, light green. Leaf 18–25 by 7.5–11 cm (7–10 by –4.50 in.), elliptical, ovate to lanceolate, petiole-leaf transition attenuate to rounded, elongated, drooping tip, with flat surface, slightly convolute at the base, no waves or slight waves margin, not rugose, shiny dark to medium green above, shiny light green below. Venation 9-11 (13), very closely spaced, sunken above, projected below. Scape 50 cm (20 in.), straight, smooth round. Sterile lower bracts small, leaf-like, with exterior bracts enveloping the interior; occasionally ±2 larger sterile leaf-like; fertile bracts navicular, broad, thick, first green, but opening white, withering late, but persisting at anthesis, 2 by 1 cm (0.75 by 0.33 in.), some larger. Raceme short, densely imbricated, 10–20 flowers. Flowers mostly white, shiny, sometimes very

In 1969, Craig imported another accession named H. tosana and was listed by Summers as No. 358. Purportedly, it originated on Izu Peninsula, which is questionable since H. kikutii (sensu lato) is not native to this part of Japan. Exact identification is no longer possible, although some of these accessions may have been H. kikutii (sensu lato).
