138 Mr. Brown on the Organs and Mode of 
Fig. 8. The Corolla of fig. 7. opened and in part removed, to 
show the state of the contained organs: the figure 
exhibiting two petals hardly cohering at base; within 
these, two distinct petal-like bodies, alternating with 
them, and which are the antherze; and two other 
smaller bodies, which are the pistilla as yet uncon- 
nected. 
9. An Anthera taken from fig. 8, and more highly mag- 
nified, to show that in this early stage it is entirely 
petal-like, there being no indication of the two cells, 
of which the first appearance in a somewhat more 
advanced stage is given at Fig. 10. 
11. A Petal of fig. 8. more highly magnified. 
12. The Pistilla of fig. 8, as yet distinct, scarcely at all 
angular, and with no manifest cavities; so that these 
two bodies may be regarded as chiefly or entirely the 
component parts of the stigma. 
13. 'Two Grains of pollen taken from the pollen mass of the 
expanded flower of Asclepias curassavica.
