Cyrtandra campanulata Reinecke

Bell-flowered Cyrtandra (Cyrtandra campanulata)

The Bell-flowered Cyrtandra occurred in the tropical rainforests of the islands of Savai’i and ‘Upolu, Samoa. 

The species had very large, up to 4 cm long hanging, bell-shaped greenish flowers.

The Bell-flowered Cyrtandra was apparently last collected in 1905 and is now most likely extinct. [1]

Cyrtandra olona Forbes

Olona Cyrtandra (Cyrtandra olona)

The Olona Cyrtandra was described in 1922, the species is known from only a single specimen that had been collected in 1909 somewhere in the Wahiawa Mountains on the island of Kaua’, Hawaiian Islands.

The species reached a height of 60 cm, the stem was unbranched and completely glabrous, the opposite leaves reached lengths of 15 to 16 cm and a wide of about 12 cm, they were broadly ovate, obtusely rounded at the apizes and truncate at the bases, their margins were crenate except for the bases. They were very dark green above and paler below.

The Olona Cyrtandra was named for the fact that it superficially resembled another endemic Hawaiian plant from the nettle family, the olona (Touchardia latifolia Gaudich.) [1]
