Stipe shorter or longer than lamina, slender, grooved, brown below, green above. Lamina oblong-triangular, 1–2-pinnate (if 1-pinnate, then basal pinnae usually divided), mid-green to dark green, membranous; rachises slender, green, grooved. Pinnae with slender stalks; pinnules obovate to triangular, c. 3–10 cm long, bluntly toothed or deeply lobed; veins obscure except for raised midvein.

VRiv, GipP, CVU, HSF, VAlp. Also NSW, Tas. New Zealand. In Victoria, known only from two localities on the Snowy Range, south of Mt Howitt. It is also rare in NSW and Tas.
New Zealand plants are 2–3-pinnate and generally more robust than Australian ones. Asplenium hookerianum can be similar to A. bulbiferum, but that species is generally larger and has less delicate fronds. In addition, the secondary pinnae of A. hookerianum are clearly and slenderly stalked, while those of A. bulbiferum are sessile or shortly stalked.
