  Leaf blade propagation

Very interesting! Not a propagation method I normally associate with Aroids, though I have had occasional leaves drop/fall off and root.

Are there specific traits that may clue into whether the plants may propagate from leaves, or is it a case of try and see?

Hi Cory,

Quite a few aroids propagate naturally from the leaf blades. Perhaps the most publicized is Amorphophallus, for which bulbil production at various junctions around the decompound leaf blade is typical in several species groups. Bulbils are also known from leaf blades in Typhonium, as well as from the petioles. To date the greatest diversity of plantlets occurring on leaf blades occurs in Schismatoglottideae. In fact there was a good paper in this, specifically in Bucephalandra, in the last IAS Newsletter. To date it is Schismatoglottis that has the most species with this phenomenon. What is particularly interesting in Schismatoglottis is that plantlet production occurs in several different parts of the genus, suggesting that it has several independent origins in Schismatoglottis alone.

Elsewhere in the Schismatoglottideae plantlet production from the main roots occurs in Hottarum and Ooia, with one reported occurrence in Bucephalandra.

Kind regards

Hi again Cory,

In answer to your query as to what traits to look for as indicating possibility of leaf blade plantlet production, in most species where it occurs it 〈just happens〉. We have, however, noticed that plants with viviparous leaf blades tend to have dimple- or pimple-like structures. Often on the underside of the blades. Keep a close watch on your plants!

Cheers

Peter

Beautiful!

Peter,

Which genera are in the Schismatoglottideae as it is currently recognized?

Thanks,

Christopher
