Huperzia australiana has decumbent stems with densely tufted, erect branches up to 300 mm long, usually branched 2 or 3 times. The
leaves are crowded, appressed to spreading, 5–9 mm long, 0.5–1.5 mm wide in the middle and tapering to a point. It
reproduces vegetatively through the often numerous small
bulbils which form along the stem. The
sporophylls are similar to the foliage leaves; no
strobili are formed; the bright yellow, kidney-shaped
sporangia are produced in the upper leaf axils. ==References==
