the Ovula of 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. 
Tas. 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 moreadvanced. The albumen has almost entirely 
disappeared, and the cotyledon is much shorter. ; 
The root has pierced the bark, the contiguous — of which 
are seen to be sphacelated ; and its sucker-like cops 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 eno ouis of a young plant of Loranthus Scurrula ? the 
upper portion of the stem being cut away. 
This shows 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 
the sphacelated margins of the bark around th 
of the same species :
