The Rabiea albipuncta seedlings are now 4 months old and growing second pairs of true leaves. When the leaves first appeared they looked like thin blades. Now they are quite succulent.
My older plant is also doing well as far as I can tell. It dried off some older leaves (the ones that were damaged two years ago) showing woody branches and got me worried for a bit it doesn't look bad and all the new growth looks fat and healthy.
Btw, I'm puzzled at the name. Neither my old plant nor the seedlings show any sign of white dots of some sort. Maybe with some imagination...
