it turns as on a hinge, and finally expands parallel to the perianth. 

 Between the stamens and the inner whorl of the perianth are two 

 series of organs, namely, five little glands, alternately with the 



Illigera Coryzadenia.

perianth-leaves, and slightly exterior to them, and ten cornets opening 

 obliquely outwards, superposed in pairs to the leaves of the inner 

 whorl of the perianth, 2 and placed a little outside the glands. The 

 one-celled ovary contains, attached near its summit, a descending 

 anatropous ovule, whose micropyle faces the placenta below its point 

 of attachment. 3 On this side the elongated style surmounting the 

 ovary is grooved longitudinally ; 4 it ends in a broad stigmatiferous 

 expansion concave above, and notched on the side corresponding with 

 the groove. The fruit is dry, elongated, and narrowly spindle- 

 shaped, but its walls are extended into two, three, or four large dry 



1 The pollen consists of large globular grains, 

 bristling with conical papilla?, and often slightly 

 mossy at the apex. 



2 The rim of these cornets is obliquely trun- 

 cate, either from before or backwards or on 

 one side. They probably correspond with the 

 glands found at the base of the starainal fila- 



ments in Gyrocarpus and the true Laurucece. 

 Their cavity secretes a viscid nectar.

4 The edges of this groove come in contact 

 without adhering, so that the hollow style can 

 often be spread out flat.
