Alsophila buennemeijeri

Cyathea buennemeijerii

Alsophila buennemeijeri (synonym Cyathea buennemeijeri) is a rare tree fern endemic to the Natuna Islands of Indonesia, known only from two low hilltops, growing to 5 m or more with fronds 2 to 3 m long. It is a wild species of cloud-forest-like scrub and is not a common garden plant, so its care is not well documented.

About

Alsophila buennemeijeri, synonym Cyathea buennemeijeri, is a species of tree fern endemic to the Natuna Islands in Indonesia. In the World Geographical Scheme for Recording Plant Distributions, these islands are treated as part of Kalimantan. A. buennemeijeri grows in open scrub at an altitude of about 600 m. This rare species is known only from the summits of two low hills. The trunk is erect and may be 5 m tall or more. Fronds are bi- or tripinnate and 2–3 m long. The stipe is dark and covered with spines at the base, as well as numerous scattered dark scales with pale, fragile edges. Sori occur near the midvein of fertile pinnules and are covered by thin, fragile indusia that resemble cups in shape.

The specific epithet buennemeijeri commemorates H. A. B. Bünnemeier (b. 1890), who collected the type material from Mount Ranai.
