Phaulopsis micrantha (Benth.) C.B. Clarke

Príncipe: N end of island, from cacao plantation along road 1.6 (air) km S of Bom Bom Island (01°40.897ʹN, 007°24.115ʹE, 65 m) to mouth of Água Grande at S end of Praia Bom Bom (01°41.390ʹN, 007°23.932ʹE, sea level), plantation grounds and moist lowland evergreen forest, 18 IV 2013 (flr) , T. Daniel & J. Shevock 11988 ( CAS) .

Although known from several collections on São Tomé ( Fig. 2 ; Daniel and Figueiredo 2009), the one cited above is the first report of the species on Príncipe where it is presumed to be native. It was collected at the same disturbed site as several other Acanthaceae that can become weedy: Brillantaisia lamium (Daniel & Shevock 11990), B. owariensis (Daniel & Shevock 11992), Dicliptera verticillata (Daniel & Shevock 11993), Elytraria marginata Vahl (Daniel & Shevock 11989), and Nelsonia canescens (Lam.) Spreng. (Daniel & Shevock 11991). Elsewhere among the islands of the Gulf of Guinea, P. micrantha also occurs on Annobón ( Manktelow 1996; Velayos et al. 2013a). Two other species of the genus, P. angolana S. Moore and P. ciliata (Willd.) Hepper have been recorded on Bioko ( Manktelow 1996).
