Tab. 27 (XXVIII). 



Fig. 1. Transverse section of a part of the tube of the perianthium, to show 

 the tliree-lobed oolumna staminea :— moderately magnified. 



Pig. 2. The inner surface of one of the three lobes of tlie column or antheral 

 annulus. 



Fig. ,3. Outer surface of tlie same :— both magnified in the same degree with 

 fig. 1. 



Fig. 4. Vertical section of a portion of one of the lobes of the columna 

 slaniinea, to show the thickness and texture of the common connective. 



Fig. 5. Transverse section of the same, which shows the original bilooularity 

 of each antliera : — both more highly magnified. 



Fig. 6. Grains of pollen, still more highly magnified. 



Fig. 7. Transverse section of the flower, to show the form and surface of [239 

 the stigma (of which the three primary divisions are opposite to the lobes of 

 the columna staminea) :— magnified in the same degree with fig. 1. 



Fig. 8. A portion of the stigma, which shows its composition. 



Fig. 9. A transverse section about the middle of the same : — both magnified 

 somewhat more than figs. 2 and 3. 



Fig. 10. A vertical section of the stigma, showing that the divisions of its 

 surface extend quite through to the cavity of the ovarium, separating it into 

 an equal number of lamellae, from the inner terminations of which the placentae 

 are pendulous : — more highly magnified than the preceding figures. 



Fig. 11. A small portion of the same, still more highly magnified. 



Fig. 12. A transverse section, more highly magnified than fig. 11, with its 

 densely crowded ovula arising from every part of its surface. 



Fig. 13. Three ovula more highly magnified than fig. 12, to show the 

 pedicellus or attenuated base and depressed or perforated apex. 



Tab. 28 (XXIX). 



A ripe fruit (fig. 1), with the stock (the root of the supposed Euphorbia, 

 fig. 3) and the decumbent angular branched stems of the parasite, from the 

 thickened trunk of which the ripe fruit originates at fig. 2, and from a branch 

 of wliich a very young flower-bud proceeds : — natural size. 



Tab. 29 (XXX). 



Fig. 1. The same ripe fruit vertically divided, with the prostrate thickened 

 stem of the parasite and the root of the supposed Euphorbia, whose woody 

 fibres and vessels appear to penetrate deeply into the substance of the thickened 

 stem: — natural size. 



Fig. 2. A portion of the fruit transversely divided. 



Fig. 3. A transverse section of one of the placentse, with the ripe seeds : — 

 slightly magnified. 



Fig. 4. Two seeds, more highly magnified than fig. 3. 



Fig. 5. A seed, magnified in the same degree as fig. 4, and vertically divided, 

 which exhibits the albumen more distinctly radiating than I have ever found it. 



Fig. 6. A seed deprived of its outer coat. 



Fig. 7- The same transversely divided, which, as well as fig. 5, sliows the 

 central globular embryo.
