MILLINGTONIA. 
Millingtonia simplicifolia, Pl. CCCCXLII, 
In this plant we have an irregular pentasepalous calyx, 
the outer sepal being the smaller and very similar to the 
bractea, a tripetalous corolla, each squamiferous in the centre, - 
two fertile stamina and a cleft disc. surrounding the ovary, 
this disk being deficient at the point alternating with the two 
fertile stamina. There is thus a high degree irregularly 
existing in the conformation of the flowers of this genus, 
the calyx being the only exception, at least so far as re- 
gards its component parts. The corolla is to be explained 
evidently by the coalition of four petals into two, and this 
is demonstrated by the size and obliquity of the single one 
and (to a certain degree) by its venation in the compound 
ones, the line corresponding to the line of union is vascular. 
This at once reduces the situation of the stamina t9 
their proper places, viz. opposite the sepals, and this is 
further corroborated by the evidently lateral situation of 
that which is attached to the single and smaller petal, 1 
and which is one-celled by abortion. oe 
We have however still to explain the relative site of the
