Averil,
I have seen a similar substance on other plants, but not my Adeniums.
The sap that the Adeniums lose is clear. I do not remember it turning amber colored afterwards.
Makes one think that possibly it is a healing process from an injury from something (insects, etc.)

Why not send a note off to durch, Chris Durham from Durham Botanicals.
He is a wealth of knowledge and has always been very gracious about receiving private quearies.

Thanks Rick, I shall send a note. I've noticed this substance a few times but the plants are very healthy
Many thanks

Hi Averil. I think you will find that it is indeed the sap. As Rick says, it runs out of the plant as a clear substance, but once it is in contact with the air it dries to a brownish colour, reminiscent of the 'syrup' you may be seeing. I have also had this happen on my plants for eg. when I have removed or accidentally knocked off a leaf. Hope this helps.

I've also seen this amber-colored substance on a few of my pachypodiums occasionally, usually coming from a broken leaf--possibly caused by some small critter thinking said leaf might make a good meal. I don't see it very often so I imagine these critters learn very quickly that pachy leaves don't taste good at all.

Averil i am no expert but i did notice a little of sap runs out when i pinched of the flower from a newly potted DR, so i agree with the rest.so keep your plant away from rain if anything to help in the healing process.but i wouldn't be concern.plant is so evolved to heal them self perfectly after a trauma.i think i read that someone here recommended using honey for their antiseptic ability.i cant remember his/her name.just what i think it is from reading .good luck
