MILLINGTONIA. 165 
I have only examined imperfect specimens of the Malayan 
plant. 
That any linear organ may have a mesial process, I think it 
is pointed out by the involucre of Hibisc. surattensis, in the 
earlier stages of which no trace exists of the subsequent 
well developed liguliform internal central process. 
Which is in the calyx an analogus to what takes place in 
the corolla of certain Bytneriaceze Guazuma etc. 
This has the same simple development by points from a 
terminal discoid cellular mass. 
The situation of the scale or appendage of either fertile 
flament is the reverse of that which takes place in the 
Simarubacee and Zygophyllee, see Lindley Introd. Nat. 
Orders, p. 129, 133, hence if they represent portions of an 
additional series of stamina, in Millingtonia they would be- 
long to the lst, and in the two orders above cited to the 
ird and fourth series, as in these two orders there is 
great probability that such is their present nature. 
ranting their nature to be the same in Millingtonia and 
ing the suppression of two petals, we shall have an 
attempt made at the development’ of four series of stamina, 
we must suppose the suppression of one intermediate series 
Which should be opposite to the petals namely 4th. In this 
“ew the first series consists of two abortive stamina, the 
Second of two abortive do. but more developed; the third of 
two fertile Stamina opposite two sepals, 4th wanting, 5 op-
