[ Aspidiaceae 三叉蕨科 ]

作者

TSAI, JINN-LAI and SHIEH, WANG-CHUENG

型態特徵

Terrestrial ferns, a few growing in crevices of rocks; rhizomes creeping or suberect; rhizome and stipe scales usually long and brown, narrowly linear. Fronds pinnate to decompound; stipes usually with a ring of vascular bundles (with only 2 bundles in Quercifilix), stipes and rachis grooved, the rachis grooves not open to rachilla grooves; upper side with ctenitis hairs along rachis, rachillae and costae in nearly all taxa; veins anastomosing in most genera, with at least one row of costal areolae, the areolae often with included veinlets, some genera with free venation. Sori usually round, dorsal on veinlets, on a plexus of veinlets, or terminal on a veinlet within an areola; in two genera (Hemigramma and Quercifilix) the sporangia follow the veins, becoming acrostichoid; indusia usually present, sometimes fugacious, round-reniform.

A family of about 20 genera with over 800 species, cosmopolitan, 9 genera in Taiwan.

型態特徵

Medium sized terrestrial ferns, rhizomes dictyostelic, covered with persistent leaf bases, usually short and erect, in two genera long creeping; stipes with a ring of several vascular bundles, usually tufted, in two genera distant or approximate, scaly at least at base; scales opaque and quite diverse in size, shape, texture and color; venation free in nearly all genera; rachis deeply grooved on upper side and usually open to receive rachillage groves. Sori round, dorsal or terminal on veins; indusia round, peltate and centrally attached or attached by a deep sinus, rarely absent, and in one genus globose and stalked.

型態特徵

Rhizomes creeping or scandent, dorsiventral, rooting only on the ventral surface and two or more rows of fronds on the dorsal surface of rhizomes. Stipes distant or tufted, bearing peltately attached, ovate or lanceolate, brown scales at base, with one or two grooves on upper side and rounded on underside; fronds dimorphic, simple or pinnate; pinnae (when present) entire or deeply lobed, in some cases jointed to the rachises; basiscopic edges of pinnae decurrent on a wing or ridge on either side of the rachises; veins free (simple or once forked) or anastomosing and forming areolae without included veinlets, or with free excurrent veinlets directed away from the costae. Fertile fronds usually with longer stipes and narrower laminae. Sori acrostichoid.

型態特徵

Terrestrial ; Rhizome short, stout, erect or decumbent, scaly. Fronds borne in a crown or cluster, often densely scaly, scales polymorphic, true hair none. Lamina ovate-lanceolate to linear, neither deltoid nor pentagonal, monomorphic or rarely subdimorphic, usually pinnate to bipinnate; rachis grooved on adaxial side, often viviparous below the foliose apex, or sometimes elongated to form a flagelliform prolongation; segments anadromous, auriculate, margin usually serrate, white-callose in some species, teeth pungent to spinulose or aristate, rarely round-crenate and revolute, chartaceous to coriaceous, rarely herbaceous; veins free, simple to pinnately forked. Sori round; indusia orbicular, peltate, persistent or caducous, rarely wanting. Spores ellipsoidal to somewhat spheroidal, with well developed perispore.

Species about 160, nearly worldwide distribution, 28 species in Taiwan.
