nearly cylindrical and erect, near the base of the albumen, with a 

 straight radicle about the length of the cotyledons. . Such at least 

 is the structure of the seeds in P. guianensia and coriacea^ where I 

 have seen them perfectly ripe. 



The stipules of Pagamea are long, vaginate and deciduous, as 

 in Gcertneray from which it differs as Psychotria does from Ghor 

 Mlia^ in the shortness of the tube of the corolla. The number of 

 parts of the flower is also usually (though not always) four in 

 Pagmnea, five in Gadrtnera \ the inflorescence is axillary, not ter- 

 minal, as might be inferred from the expressions in the *Pro- 

 dromus.' I have at least always observed two opposite axillary 

 peduncles, which in the early stage appear to terminate the 

 branches ; but th6 bud between them soon grows out, leaving 

 the pedimcles one on each side at the base of the young shoot, 

 instead of a single terminal peduncle in the dichotomy of two 

 young shoots. 



The whole genus has but a limited rknge in East tropical 

 America. The old P. Ch^ianemis is the widest spread, extending 

 over Guiana and North Brazil ; P. capitata is confined to Guiana 

 and Surinam ; the three others have only been found by Spruce 

 on the Tipper Eio Negro.

 nothing to add to the detailed character in Blame's * Museum

 phrase ** cotyledonibus e basi tumida subulatis " does not refer at 

 least to the G. tltyrsifloray where the cotyledons are short and 

 thick. The seeds have, however, only been examined in a very 

 few species. These are now rather numerous ; for besides the
