NATURAL HISTORY OF PLANTS. 



V. PHYTOCEENE SEEIES. 



The flowers of Phytocrene'^ (fig. 330-333) are dioecious, very 

 analogous to those of Mafj>ia. In the male a small convex receptacle 

 supports a perianth,^ with three or four valvatc leaves, more or less 

 coherent at first at the base, then completely free, reflexed at the 

 apex, valvate in the prefloration. The androceum is composed of 

 an equal number of alternate stamens, whose free exserted filaments 



Fhytocrene macrophylla.

are attached towards the base of a small rudiment of a columnar, 

 upright gynjBceum, surmounted by a more or less voluminous bundle 

 of hairs. The anthers are introrse, the two cells, independent of each 

 other, and each opening by a longitudinal cleft, inserted towards 

 the middle of their height at the edges of a small rectangular con- 

 nective. In the female flowers, the perianth is nearly the same as in 

 the male, sometimes persistent round the base of the fruit, with three 

 or four valvate leaves. In the intervals of these are found stami- 

 nodes, equal or fewer in number, very small and glandular-shaped. 

 The gynseceum is free, formed by an unilocular ovary, surmounted 

 by a large upright cylindrical or clavate style, traversed in its whole
