the Ovula o/'Loranthus and Viscum. 87 



Fig. 6. Germinating embryo of a Loranthus, species unknown, the albumen 



remaining attached and inclosing the cotyledons. 

 The radicle of the parasite has not yet pierced the bark of the 



stock. 

 Fig. 7- Ditto. Removed from its attachments and from the embryo ; the half 



sphacelated cotyledons are somewhat separated. 

 Fig. 8. Albumen and cotyledonary end of the same embryo. 

 Fig. 9. One of the cotyledons and plumula. 

 Fig. 10. Germination of Loranthus rather advanced. The root has at this 



period perforated the bark. The rudiments of the second pair of 



leaves are visible. 



Tab. VIII. 



Fig. 1. Fruit and germinating embryo of Loranthus Scurrula cut through lon- 

 gitudinally. The plumula is just exserted ; the radicle has not yet 

 pierced the bark of the stock ; some of the viscum is seen adhering 

 to the fruit. No change has yet taken place in the cotyledon. The 

 radicle has become whitish in the centre; the irregular shape of 

 the sucker-like portion is visible, and appears to result from the 

 small opening in the parietes of the capsule. 



Fig. 2. Ditto, considerably more advanced. The albumen has almost entirely 

 disappeared, and the cotyledon is much shorter. 



The root has pierced the bark, the contiguous portions of which 

 are seen to be sphacelated ; and its sucker-like extremity is seen to be 

 expanded on the surface of the wood. The first pair of leaves have 

 reached to a considerable size ; one, however, is cut away. This is 

 viewed obliquely. 



Fig. 3. More advanced state of a young plant of Loranthus Scurrula 9 the 

 upper portion of the stem being cut away. 



This sho^ws the great irregularity of the base of the axis of the 

 parasite, the incomplete ring formed round its base in the ligneous 

 system of the stock, and the lateral shoot. 



Fig. 4. A similar young plant more advanced, perhaps of the same species : 

 the sphacelated margins of the bark around the base of the parasite,
