Lateral pinnae 4-7 pairs, basal pair largest, ovate-deltoid, 20-30 × 10-14 cm, with stalk 1.5-3 cm, trifoliolate or pinnate; upper pairs trifoliolate or simple; third pair of pinnae lanceolate, 16-22 × 2.5-3 cm, shortly stalked, base rounded or rounded-cuneate, margin with sparse, short, blunt teeth, apex caudate-acuminate or somewhat acute; terminal pinna larger than adjacent pinnae, often divided with a small segment at base. Pinnules of basal pinnae 1-3 pairs, basal basiscopic pinnule longer, lanceolate, somewhat arcuate, 10-15 × 1.5-2.5 cm, base rounded-cuneate, margin with sparse short teeth, apex caudate-acuminate; terminal pinnule largest. Veins 2-forked; hydathodes spindle-shaped, not extending to base of teeth. Sori extending to 3/4 of veins.

Coniogramme venusta is similar to C. intermedia var. glabra, but its hydathodes are spindle-shaped and do not extend into the teeth.
