Explanation of Figures. 
All figures except Figs. 13—16 are drawn with the aid of the camera 
lucida from the fresh materials and magnified 130 times. 
Fig. 1. An adult embryo in a ripe seed. 
Fig. 2. The same shown in optical section. Fragments of testa are 
attached to the radicular end, 
Fig. 3. A seed at the beginning of germination, with some swollen 
epidermal cells at the radicular end appearing outside the testa. 
Fig. 4. A seed at somewhat later stage. 
Fig. 5. An embryo in the germinated seed as shown in Fig. 3. 
Fig. 6. The same in the seed shown in Fig. 4 (optical section) Starch- 
granules accumulate at the median portion. 
Fig. 7. E-adicular end of a seedüng showing one of the globular cells 
protruded into a papilla. 
Fig. 8. The same with full grown tendrils. 
Fig. 9. The same showing one of the tendrils attached to a host {Zingiber). 
Its apex is penetrating between two epidermal cells of the host. 
Fig. 10. The same with a much shrinked tendril. 
Fig. 11. The same with a tendril twined round a root-hair of a host 
(Zingiber). 
Fig. 12. Two seedlings at advanced stage. In the right is shown an 
entire embryo taken out df the endosperm. 
Figs. 13—15. Tubercles at several stages of development, ca. 40. 
Fig. 16. A shoot and roots derived from a tubercle. Hat. size.
