PUtopis has flowers very analogous to those of the preceding 

 genera, especially Genipa ; they are surrounded by bracts covered 

 with silky hairs, like the calyx. The latter is valvate and divided 

 into irregular lobes. 



The corolla, contorted Xouhubea insignis. 



and its throat covered 

 with hairs, bears from 

 four to six stamens 

 with bearded filaments. 

 The two ovarian cells 

 contain each an in- 

 verted triangular mul- 

 tiovulate placenta, and 

 the two terminal lobes 



of the style are short 



and thick. They are 



hairy trees of eastern 



Peru, with flowers in 



terminal trichotomous 



cymes. The Brazilian 



BilUottia has dioecious 



flowers like those of 



Amaioua to which it is 



closely allied. The 



corolla, hairy at the 



throat, is of four or 



five parts and the ovary 



is said to be 3-5-celled. 



The female flowers are 



terminal and solitary; 



the males, in corymbiform cymes. They are pubescent shrubs with 



intrapetiolar stipules united in a sheath which finally divides.' 



Stachyarrhena, fi:om the same regions, also has solitary female flowers 



and the ovary is divided into a variable number of cells ; but the

1 We know not whether to preserve distinct 

 or to refer to the genera BilUottia or Amaioua { f ) , 

 Schachtia, a Golumhian tree, with enlarged 

 internodes, the dioecious flowers of which are 



constructed nearly as those of the types just 

 mentioned ; the males solitary and the females 

 grouped in cymes on ehort axillary branches.
