Leptopteris moorei " "'is a fern in the Osmundaceae collected plants on Lord Howe Island in 1869.
Species in the genus " Todea ", as " Leptopteris ", are distinct from other in Osmundaceae in that sporangia are born on laminar pinnules.
The fern genus " "'Leptopteris " "'is a small group of plants found growing in the Pacific Islands, New Guinea and Australia.
In these genera the sporangia are borne naked on non-laminar pinnules, while " Todea " and " Leptopteris " bear sporangia naked on laminar pinnules.
The leaf tissue ranges from very coarse, almost leathery in the case of the Cinnamon fern ( " Osmundastrum cinnamomeum " ), to delicate and translucent, as in the case of the genus " Leptopteris ".
