I. Introduction
Plant diversity in the Republic of Congo (Brazzaville) still poorly studied and documented.
The research visit I made in Wageningen in
October 2011 retained my attention on the fact
that specimens from the Republic of Congo were
less represented in comparison with those from
Gabon, Democratic Republic of Congo and
Cameroon. The need for specimens from Congo
Brazzaville is also supported by Breteler (2010a)
when doing the revision of the genus Anthonotha.
This project was carried out in order to continue
the collaboration the plant experts in the
Netherlands as well as providing materials from
the Congo to contribute to plant taxonomy studies.
II. Study area
The fieldwork was carried out in the forest around Bomassa. The village is located in the
north of the Republic of Congo (2.20400° N, 16.18717° E; see Map 1). Bomassa is the
village is where the main headquarter of the Nouabalé-Ndoki National Park (NNNP) is
based. The park itself is approximately 25 km away from Bomassa to the East.
Specimens were also collected in another small village called Bon Coin which is situated at 2
km NE from Bomassa.
III. Vegetation type of the study area
The Forest around Bomassa village was first
selectively logged in 1970s by a company
called “Bois Sangha”. Thirty years later a
second selective logging (cut of trees which
were left during the first cut because of their
small logging diameter) was carried out by
