小车前蕨 xiao che qian jue

Antrophyum reticulatum (G. Forster) Kaulfuss var. parvulum (Blume) Beddome; Hemionitis parvula (Blume) C. Presl.

Rhizome short erect; scales brown, lanceolate, margin minutely denticulate, clathrate. Fronds clustered; stipe indistinct, appressed, base covered with small scales, gradually glabrous; lamina leathery, oblanceolate, spatulate, or oblong, 1-6 × 0.5-1 cm, apex acuminate or rounded, often lacerate or bifurcate, base attenuate; costa indistinct or only visible at lower 1/3; veins abundantly reticulate, invisible on both surfaces. Soral lines slightly immersed, forked but not netted; paraphyses club-shaped with a capitate head. Spores trilete, tetrahedral-globose, surface papillate.

Epiphytic on tree trunks or on limestone; 400-1600 m. Hainan, Taiwan [India, Indonesia, Malaysia, Philippines, Thailand, Vietnam].

Antrophyum parvulum might be conspecific with A. immersum (Bory ex Willdenow) Mettenius, which needs further studies. It is quite different from A. obovatum by its small size and indistinct stipe.
