Type: C. Versteegh BW 3041 (L, holo), Wissel Lakes, West Irian. Syn: D. nidulum var. araucariodes de Laub. 1969 (de Laubenfels 1969, 1988). Note that de Laubenfels assigned the epithet cornwalliana, an incorrect conjugation.
"Tree 10-30 m tall, with elongated dense fastigate crown . Juvenile leaves up to 12 mm long, strongly curved forward parallel to the branch and soon becoming incurved, 0.4-0.5 mm wide and 0.2-0.3 mm thick, sharply apiculate. Adult leaves crowded and touching near their tips, spreading but then incurved towards the tip which is directed somewhat inward towards the branch, distinctly apiculate, 2-5 mm long, the longer examples on protected branches or younger trees, strongly keeled on the back and slightly concave on the ventral side but with a small ridge over the midvein, 0.6-0.8 mm wide and 0.3-0.4 mm thick. Fertile structures terminal, often on short lateral shoots but pollen cones may also be lateral. Pollen cones c. 12 mm long and 1.8 mm in diam. Microsporophylls c. 0.8 mm long. Seed-bearing structure as in D. nidulum, becoming fleshy and red when ripe. Seed c. 5 mm long" (de Laubenfels 1988).
W & C New Guinea. "Dominant to nearly pure stands in swamp forests and perhaps also mossy heath forests between 1450 and 2300 m altitude" (de Laubenfels 1988).

Laubenfels (1988) does not explain the origin of the epithet. There are no places called Cornwall in New Guinea, nor botanists named Cornwall who have done work there.
