FIG. 5 in Lygodium hians E.Fournier (Pteridophyta, Schizaeales) - an endemic unusual groundclothing member of a modern climbing fern genus in New Caledonia
FIG. 5. — Blade details in Lygodium hians E.Fournier from Plateau de Dogny, New Caledonia: A, long blades from Figure 2A showing morphology and basal dichotomies; B, blade from Figure 2A showing various arrangements of lateral vein departure from mid-vein, open dichotomous venation with up to two dichotomies, and denticulate margin with vein endings not related to position of marginal teeth; C, tip of short blade from right frond in Figure 2A showing insect damage and wound reaction tissue. Page 23222, Herb E. Scale bars: A, 1cm; B, 2 mm; C, 1 mm.
FIG. 4 in Lygodium hians E.Fournier (Pteridophyta, Schizaeales) - an endemic unusual groundclothing member of a modern climbing fern genus in New Caledonia
FIG. 4. — Herbarium sheets from other collections of Lygodium hians E.Fournier including lectotype: A, herbarium sheet of Lygodium hians from Mt. Arembo (New Caledonia) showing both a dichotomous determinate ground-clothing frond and a climbing fertile frond, the latter with terminal and sub-terminal sorophores (MNHN, P00630569, Herb. P); B, lectotype of Lygodium hians from Mt. Humboldt (New Caledonia), showing a climbing frond with terminal and subterminal sorophores (MNHN, P00523232, Herb.P). Sheet height: 42 cm.

FIG. 2. — Dichotomous form of ground-clothing fronds of Lygodium hians E.Fournier: A, herbarium sheet of specimens from Plateau de Dogny showing blade form. The reduced length of some blades (right frond and right blade pair of centre frond) is due to extensive insect feeding damage (detail in Fig. 5C). Page 23222, Herb. E; B, stylised diagram of end and side view showing characteristic structure. Abbreviations: a, abscission zones; b, blades; d, double true-dichotomies at top of main stipe; h, height 15 (9-20) cm; S, stipe, distance between stipes 8-15 cm. Scale bar: A, 4 cm.

FIG. 1. — Forest habitat (A) and forest floor (B) of the Lygodium hians E.Fournier colony on Plateau de Dogny, c. 710 m, New Caledonia.; A, natural vegetation showing temperate character of relatively open, mature forest community (lacking, for example, in such tropical fern families as Cyatheaceae and Gleicheniaceae, which are abundant at lower, more tropical altitudes). The surrounding nearby forest-floor vegetation also contains abundant Blechnum L. ferns; B, fronds of part of the colony, showing predominance of typically dichotomous-bladed vegetative frond growth, with some variation in blade form. The conifer seedling is Austrotaxus spicata Compton.

FIG. 10 in Lygodium hians E.Fournier (Pteridophyta, Schizaeales) - an endemic unusual groundclothing member of a modern climbing fern genus in New Caledonia
FIG. 10. — Scenario for the predominance of the climbing frondform of Lygodium Sw., developing from a basic dichotomous structure. A, a theoretical initial stage in which a series of simple sequenced dichotomies form a successive set in which left and right branches become alternatively indefinitely developed; B, the shorter branches of each non-continuing dichotomy are each soon 'stopped' from further indefinite development by establishment of a non-continuing terminal bud, but with a lateral 'pinna' pair of definite growth forming a pseudo-dichotomy; C, the typical frond-form in most modern Lygodium species in which each noncontinuing dichotomous branch and its arresting bud are eventually reduced to nothing. Paired 'pinnae' only remain, and these may bear further sets of foliage in successive complex 'pinna' arrangement developments in individual species.
