PREFACE. XXXIX 
objection to tbe existence of such a form, although it 
would be reasonable to expect, that the axis of such 
a stigma would not correspond with the axis of the 
style. 
Comparatively sudden reduction from a broad to a 
narrow surface is not uncommon in leaves, all apicu-, 
late or cuspidate leaves are instances, and of these, none 
can be more striking than that of the peepul. 
But though a continuation of the placenta along eiger 
margin to the commencement of the apex of thmi- 
drib, would constitute the simplest form of stigrá/, yet 
it is still necessary to allow either an increaseof the 
margins, or a spreading out of the stigmatic surface 
over the narrow part of the cauda or apiculus to ex- 
plain those stigmatic lines which occupy the whole in- 
ner face of the style, excepting perhaps the miğrib itself, - 
such for instance as Escholtzia. 
Stigmata are continuations upwards of ls > placente, 
they are consequently double, and have tid same rela- . 
tion to the leaf as the placente. ~~, | 
There is perhaps scarcely a modification m em 
of leaf, which may not be met with i in an extensi T 
examination of carpellary leaves. 2 
Thus such instances of bilobed styles as occur in 
Iris, Meyenia etc., are representations of an emargina- 
ted bifid, or bilobed leaf, the true apex of the one is 
pointed out by the apex of the midrib, which is un- 
divided, in the other by a protuberance, or when this 
is not evident by the termination of the central vas- 
cular bundle.
