Rothmannia octomera

A fairly common sight was this spectacular Rubiaceae. I now figured out it is Rothmannia octomera. It is a fairly slender shrub. The flower have this amazingly long an slender tube more than 20 cm long. The corolla is about 8 cm in diameter. Unusual for this genus the corolla has more than 5 lobes and lacks the purple-marroon spotting of other Rothmannia spp. The buds take a long time to develop and open but strangely are very short-lived. They appear to open at night and are often already keeling over in the morning but I was lucky with som still being in good form. I reckon that, like many white flowers with long tubes or spurs they are pollinated by moths. They may well be very scented at night but I did not notice it particularly during the day. The rather strange young fruit like courgettes about 8-10 cm long
