Hep. 1898. * Colenso realised that this species was similar to T. tenellus, but was confused by the wrong description of its marsupium, “elongate, obconico, striato”—a description which applies to the marsupium of T. saccatus, T. tenellus being considered a form of T. saccatus. Gymnanthe (Marsupidium) hirsutum Col., Trans. N.Z. Inst., xiv, 340, 1881. Plants variable, with creeping radicellose rhizomes spreading in patches, dioicous, on logs, bases of trees and ground, bright green when fresh. Stem to 3 cm, flexuous, simple or branched, often from the base. Leaves small and distant on the lower portion of the stem with few rhizoids, remote to contiguous higher up, to 2.5 mm, often shorter, convex, bilobed, dorsal margin mostly recurved, nearly straight, decurrent, ventral arched, serrate near the apex, and often acuminate, leaf-apex variable, ventral lobe larger than the dorsal, sinus often serrated to where the dorsal lobe starts. Cells hexagonal, 30–40μ, walls thickish. Marsupium 3 mm from between 2 small leaves, narrowly obovate, setose, clothed with bristly hairs. ♂ bracts leafy, in few pairs, usually on mid-stem, basal portion saccate, upper portion as in ordinary leaves. This species is omitted from the Flora Novae Zelandiae and the Handbook, as Mitten, also Taylor (1847) considered it to be a form of T. saccatus. But the authors of the Synopsis would not accept this, nor did Stephani. It differs from T. saccatus in the shorter leaves, which in most cases have a more arched ventral margin. The apex of T. saccatus is more truncate with a very shallow sinus, and the ventral margin and apex are entirely serrulate, while the marsupium is long and narrow and not setose, but very rarely found fruiting. Dr. Arnell agrees that T. flaccidus Berggr. is T. tenellus. North Island: Papa cutting, Nihutapu Valley, Auckland, E. D.
