of the Stamina of Plants. 5 
they can only be distinguished by having no Antherw: nay in 
Canna, we have even an instance of the male parts of the flower 
passing into the female, where the innermost lacinia of the Co- 
rolla to which the Anthera is attached, always coalesces more or 
less, so as to form one and the same lamina with the dilated pe- 
taloid Style. Jussieu adopts the Linnzean definitions of Calyx 
and Corolla somewhat amplified ; but in his practice, if I may 
use a vulgar expression, he does not stick to his text. He says, 
* Calyx integumentum floris exterius, est corticosa pedunculi floralis 
* productio. Corolla, interius tegumen, pedunculi libro non epider- 
. * midi continuum, non persistens, sed cum staminibus plerumque deci- 
* duum fructum involvit aut coronat, nunquam cum ipso concrescens, 
** et suas partes cum staminibus numero equalibus sepius alternans.” 
He then quotes Narcissus as an example of an integument, which 
growing to the fruit with stamina opposed to its div. » must 
consequently be a true Calyx. Here I think that consummate 
Botanist mistaken : for, the Spatha appears to me the first expan- 
sion, of what has been hitherto erroneously called Epidermis, and 
to supply the place of a more perfect Calyx in that Natural Fa- 
mily : nor can I see that the integument is joined to the Pericar- 
pium in a different way from that of many other truly epigynous 
flowers among the Dicotyledones: lastly, what weighs with me 
more than every other consideration is the affinity of the part in 
question to the Stamina, a character the importance. of which 
Jussieu owns in gizong te terms ; ; “ Corolle magna cum staminibus cog- 
natio" is his expression. I was glad | to find these sentiments cor- 
roborated by Mirbel, x runs ; into the other extreme however; 
for he says, that as the Calyx is a continuation of the bark, and 
that many of the Monocotyledones have no bark at all, in those 
genera which have only a single integument it must necessarily 
be: Corolla. He also proposes that the integument of all flowers, 
whether
