Hi Stephania,

Thanks for the link.

The flowers are indeed small, but fascinating in structure.

It's interesting that many of these caudiciform plants have separate male and female flowers.

I note too that in Hong Kong these plants are sold for medicinal purposes for treating anything from colds to cancer!

Cheers,
Colin

Could they be tissue cultured I wonder? that may be a way of dog it if sexing is so hard

Stephania,

Have you tried growing stephanias from vine cuttings?

Cheers,

Hi

yes ,this does seem very worrying, as they are so very slow to grow & propagate, are they still available to buy at the markets ?, are they very expensive?.

varied collection of succulents and cacti but I especially like Euphorbia's and variegated agaves.

Hi Colin, Thanks for your informations, and I found some more.

According to a study of L.L. Forman of Royal Bot. Gar. Kew in Flora of Thailand Vol. 5 part 3,
he revised this climber family and conclude that
genus Stephania comprise of at least 45 valid species,
in the old world tropic,
15 found in Thailand, among these 7-8 species form a tuber caudex.

S. erecta is a synonym of S.pierrei, which form a rounded underground caudex
and also found in my country, Thailand too.

In fact, I found some species ( S. glabra) can form caudex at nodes along the perennial vine which touch to the ground, but much smaller or irregular shape than the original caudex.

Gordon Rowley the author of 'Caudiciform and Pachycaul Succulent' mentioned the success of cutting method for propagation these genus too, but I didn't try, if they could from a huge caudex as in seed plant or not.
