indusia that are saucer-like in appearance.[2]
Taxonomy
Alsophila javanica appears to be most closely related to Alsophila doctersii. Large and Braggins (2004) note that A. doctersii may in fact be of hybrid origin between A. javanica and a member of the Alsophila latebrosa complex.[2]
When
Carl Blume described A. javanica (as Cyathea javanica), he also named one variety, rigida. Large and Braggins (2004) note that although variety rigida is apparently part of the A. javanica complex, the name has also occasionally been associated with Alsophila polycarpa.[2]
