1. F.Jilamentosa, (Benth. in Hook. Journ. Bot. 2. 127.) 

 pinnis 10 — 15 jugis, foliolis 30 — 50 jugis lineari-falcatis, 

 staminibus sterilibus 5, corolla multo longioribus. — British 

 Guiana, Schoniburgk ; St Vincents, Guilding. 



2. P. brevifila (Benth. 1. c.) pinnis 10 — 15 jugis, folio- 

 lis 30 — 50 jugis lineari-falcatis, staminibus sterilibus 5 corol- 

 la brevioribus. — Borba on the Rio Negro, Langsdorff. 



3. F. macrophylla, (sp. n.), pinnis sub 10-jugis, foliolis 

 8 — 15-jugis oblongo-rhombeis obllquis, staminibus sterilibus 

 10 — 15 tenuissimis — Folium unicum tantum vidi amplum, 

 foliolis plerumque pollicaribus 4 — 5 lin. latis. Spicse 4 — 5- 

 pollicares, tenuiores quam in proecedentibus. Flores minores. 

 Stamina fertilia corolla duplo longiora, glandula antherarum 

 parva. Filamenta sterilia tenuia, corolla multo longiora, 

 sed in fundo corollas plicato-crispa, ita ut lacinias coroHinas 

 non adffiquant. Legumen pedale, lignosum ex Heudelot,
