1. Germination of Scyphostegia borneensis is epigeal (or phanerocotylar). 2. The chromosome number has been found to be n = 9 and 2n = 18. 3. The somatic chromosomes are almost V-shaped, relatively symmetrical, each having a median or sub-median centromere. 4. Chromosomal information of Scyphostegia gives additional evidence for excluding this genus from the Monimiaceae.
