had each cell marked along the middle with a longitudinal furrav»f, 

 and contained pollen ; hence I infer that they are fertile^ and open 

 by slits (not by valves^) but I have seen none after dehiscence, and 

 as at the same time they bear the closest resemblance to the stami-* 

 nodia of many genera of Laurineae, so it is not improbable that they 

 may be sterile, and that the fertile ones (on a different plant) do 

 open by valves. If this view were to be adopted, Hortonia Avould 

 be more allied to Atherospermese, particularly to Laurelia (the fila- 

 ments of which are likewise furnished with a couple of glands at 

 their base, as in Laurineaj,) but in all the Atherospermeee the ovule 

 is described as erect, not pendulous, and the style is long, persistent, 

 and plumose. At present, Hurtouia ought perhaps to be consider- 

 ed as a connecting link between Monimiacea and Atherospermeee, 

 agreeing with, but at the same time differing from both, in several of 

 their peculiar characters. The flower buds, if they may be so call- 

 ed, resemble those of a double flowering myrtle, and are very fre- 

 quently injured and internally deformed from having been attacked 

 by the larvae of insects. 



In Lindley's Introduction to the Natural System, all the species of 

 Monimiaceae are said to be natives of America ; this is surely a mere 

 inadvertency ; a very few only are found in the New World.
