Linn. Proc. Bot. vi. p. 151. Shewing C. trident alum, Monachan- 
thus viridis, and Myanthus barbatus to be three sexually diverse 
forms of the same species, viz., C« tridentatum; the male with 
well developed pollinia, liberated by the elasticity of the caudicles 
on the rupture of the membrane of the rostellum surrounding 
their disk. This rupture is shown to be occasioned by the stimulus 
of a touch conveyed to the rostellum by the curved arms, called 
by Mr. Darwin antennae , projecting in front of the column. 
The stigmatic surface is not viscid, and the ovules are more or 
less atrophied. Monachanthus is the female form, with rudimen¬ 
tary pollinia, and destitute of antennae, but with well developed 
ovary and viscid stigma. Myanthus, the hermaphrodite, having 
the column erect, not inverted as in the other forms, and the 
labellum remarkably different: with smaller pollinia than Cata¬ 
setum and stigmatic cavity intermediate in size between the two 
other forms.

•- Note sur un nouveau Caractere observe dans le fruit des 
Chenes, et sur la meilleure division a adopter pour le genre 
Quercus. Bibl. TTniv, Oct. 1862. M. De Candolle finds the 
position of the atrophied ovules in the species of Quercus useful 
in affording sectional characters, especially (together with the 
period occupied in the maturation of the fruit, whether one 
or two seasons) of the group Lepidobalanus. At the same time
