It's been said that Pachypodium ambongense is the lost pachypodium.
Never been seen until 1990.But i can't find any solid Reference supporting this.
MY reference:
Illustrated Handbook of Succulent Plants: Dicotyledons
The last species to be introduced to cultivation.
Pachypodium in Madagascar
Consequently,an accurate classification was't possible and this remarkable remain largely unnoticed until the late eighties when about a hundred specimens from madagascar were sent out to the world
P. ambongense Poiss. in Bull. Acad. Malgache 6: 162, 1924
This is the last species to be brought into captivity, again thanks to Professor Rauh (1995), and is still the least known. First in the field with a published picture of a potted plant in bloom were the Japanese. In Succulent ( J. Jap. Succ. Soc.) 292: 1, 15, Oct. 1991. Hitherto it was only known from a herbarium specimen and Poisson's terse diagnosis of 1924.

To quote Gordon Rowley's book of 1999:
P. ambongense Poiss. in Bull. Acad. Malgache 6: 162, 1924
This is the last species to be brought into captivity, again thanks to Professor Rauh (1995), and is still the least known.
