EXPLANATION OF FIGURES IN PLATE XVII. 
Illustrating Dr. Schonland’s paper on the Morphology of the Mistletoe 
( Viscum album , L.). 
[All figures represent diagrams of flowering shoots as actually observed by the 
author, with the exception of Fig. 9.] 
\_A= mother axis of each shoot; B = bract; / = prophyll; L = foliage-leaf ; 
b = axillary bud; /= scale-leaf corresponding to i; s and s' = scale-leaves in 
inflorescences.] 
Fig. 1. Normal female shoot (after Eichler). 
Fig. 2. Normal male shoot. 
Fig. 3. Male shoot in which the posterior foliage-leaf has split into two ; the 
anterior leaf shows beginning of splitting ; the terminal inflorescence is also abnormal. 
Fig. 4. Trimerous female shoot. 
Fig. 5. I. Trimerous male shoot ; one lateral flower is not developed. II. Tetra- 
merous male shoot ; one lateral flower and the terminal flow^er are not developed. 
The two median lateral flowers are trimerous, and occupy the apex of the shoot. 
Fig. 6. Tetrarnerous male shoot ; one lateral flower is trimerous, another penta- 
merous. 
Fig. 7. Male shoot with five flowers developed from a dormant bud. In the 
place of the two foliage-leaves, scale-leaves are developed which also bear flowers 
in their axils. 
Fig. 8. I. A similar case as represented in Fig. 7, only the two lateral flowers 
are suppressed. II. Case similar to the preceding one : a further reduction has 
taken place by the suppression of the uppermost pair of scale-leaves. 
Fig. 9. Male shoot with hexamerous terminal flower (after Eichler).
