Plate 24: C. submersum Herbert

Figure 24 Fig. 24: Crinum x submersum Herbert is a natural hybrid found in Brazil. It is an obvious cross of C. scarbrum and C. americium, and is quite sterile. Numerous duplicate crosses, man-made or hummingbird pollinated, have appeared since Herbert's time. The variants amongst both C. americanum and C. scabrum result in significant diversity as shown in Figures 25 and 26 below. Usually the petals are intermediate in form, indicating some intermixing of genes.
