minute embryo agree with Magnoliacee; but the serrate leaves, 
with a sheathing base without stipules, are nowhere found in that 
order. In this character of the leaves—and further, in their close 
straight venation— we have an approach to Dilleniace:, from which 
the samaroid carpels and the want of an aril are sufficient dis- 
tinctions. Anonacer and the other apocarpous families are too 
different to afford grounds of comparison. 
The nearest affinities of Luptelea appear to us to be with 
Ranuneulacee and Magnoliacee ; and though, in the absence of 
floral envelopes, there is no very marked line of demarcation be- 
tween these two families, yet the woody habit and the structure 
of the seed incline the scale in favour of Magnoliaces, in the 
first section of which, Winteree, which is characterized by the want 
of stipules and by the carpels forming a single verticil, we propose 
for the present to leave this very anomalous plant. 
Were it not that Siebold and Zuccarini described their plant 
as one-ovuled, we should consider the Indian species identical with 
that of Japan. As this is a point on which a mistake is not pro- 
bable, we propose to call the Mishmi plant E. pleiosperma, resting 
the diagnosis on the presence of 2—4 seeds in the ripe samara*.

This species, so well figured in the * Musci Exotici,’ has been 
long misunderstood from Dr. Taylor's mistake in considering the 
perianths to belong to some Aneura accidentally intermixed with 
the original specimens; but so great is the resemblance of the 
* Within the last few days we have had an opportunity, through the kind- 
ness of Professor Miquel, of examining the carpels of E. polyandra, which are 
one-ovuled, as figured by Siebold and Zuccarini.
