 endosperm, the yellow and much more sticky viscin around the head left. /. Embryo 

 dissected out from fruit seen from side, y. From the side of the slit (for plumule). Note 

 lack of symmetry of embryo whilst in the fruit. 



8. Germinating seedling of L. Gardneri on leaf of wild Durian. Entry has been etfectcd and a 

 lateral root thrown out.

 endosperm and hypocotyl green, d. Seeds of V. orientate issuing basally from fruit-coat. 



10. a. R^^e iraity A'otot/dxos floccosus. b. Seed with inner layers of fruit-coat (not viscid) at side 



and viscid basal thread; endosperm green, c. Germinating seed of ditto, free end of hypo- 

 cotyl not swollen to a head. 



11. Loranthus longijtoras. Flower; buds show slits at the bases of the corolla-lobes. 



12. L. tongiflorus. F>uits. 



13. a. Endosperm surrounded by viscin, which is continued above into 5 or horns (r/. fig. 10). 



b. Section through endosperm showing young embryo. 



14. Section through nearly ripe fruit. 



15. a,b. L. lonffijtorus germmnUn^. c. Ditto: ventral aspect of disc of hypocotyl.

Fig. 1. LorantJius tomentosus, var. tanvginosus, showing the positions of the corolla-lobes, stamens, and 

 style after explosive opening. 



2. Fruits of L. cuneatus. 



3. Flowers of same. a-e. Successive stages. 



4. Lorantfms toniceroides. FVuit. 



5. L. toniceroides. a. Shows seeds issuing basally; to the base of the seed sticky viscin is 



attached, b. Germinating seeds, showing apex of hypocotyl, and cotyledons not fused. 



c. Apex of hypocotyl. 



6. L. toniceroides. d. Successive stages of germination and attachment, e. Firmly attached to 



host ; it has excised its cotyledons and endosperm, exposing the plumule. /. Young plant 

 from whose swollen base a lateral root is arising. 



7. L. toniceroides which has failed to reach a host, head not swollen, and grown out into irregular 



■white mass. 



8. Group of seeds oi Loranthus toniceroides and Viscum orientale found together on a branch. 



9. L. toniceroides grown so that the head of its hypocotyl was in contact with tinfoil. At the 



place of contact a projection is thrown out.
