NATURAL HISTORY OF PLANTS. 



Phycosalymma ; the flowers are hexainerous, -witli six tongues 

 alternating with the sepals, a 12-androus andrcecium or formed of 

 an indefinite number of stamens, a sessile ovary, a non-accrescent 

 receptacle. The inflorescence is that of Lafoensa. 



II. CRYPTEEONIA SERIES. 



Grypteronia'^ (fig. 412-415), referred by authors to various other 

 groups,^ appears to comprise somewhat abnormal Lyth/rariacece, whose 

 flowers are regular and polygamo-dicecious. The hermaphrodite 



flowers (flg. 412, 413) have 



Crypteroniajmaniea. ^ CUp-shaped rOCeptacle, the 



margin of which bears flve^ 

 sepals and five perigynous 

 stamens, alternating. Each 

 is formed of a filament in- 

 curved in the bud, sur- 

 mounted by a basifixed 

 anther, united below by a 

 glandular connective, de- 

 hiscing superiorly by a 

 longitudinal cleft, marginal 

 or more or less introrse. 

 The gynsecium is composed 

 of an ovary in greater part 

 superior, with two or more rarely three cells (fig. 413), complete or 

 incomplete, surmounted by a style with stigmatiferous extremity, 

 slightly enlarged at the top. In the internal angle of each cell, 

 sometimes near its exterior wall, sometimes more or less near the base, 

 is a placenta * bearing a great number of anatropous, transverse (fig. 

 415) or more or less ascending (fig. 413) ovules. In the female 

 flowers, the gynsecium being the same, the stamens have sterUe 

 anthers. In the male flowers (fig. 414, 415), the receptacle is less
