First published as a Psychotria in 1913, it was only known from a single specimen, from Oban, Nigeria, until the 1990s when botanical surveys on the lower slopes of Mt Cameroon found it to be fairly common in the Onge forest and also present at Bimbia; here it is highly threatened by expansion of plantations.
Chazaliella obanensis is also fairly common on the lower slopes of the western side of Mt Kupe, indeed it is the commonest member of the genus in Bakossi, with over 20 specimens known. However, most of these specimens occur below 1,000 m alt. and so are particularly vulnerable to expansion from agriculture. It is estimated that 30–50% of the global habitat of this species is likely to be lost in the next ten years.
