Vexilli violacei indicium nectaris saturate violacenm, 

 colore flavescente cinctum. 



Ambse s])ecies, 2)cduncularis et clitorioides, ea nota commmii 

 excellunt, qiiod carina minus spiraliter torta cqnce spiram imam 

 format (nec trispiralis vel ultra, ut in speciebus proximis). 

 Quse res e dispositione specierum in »Flora Brasiliensi» non 

 patet. Quse quum ita sint, non dubito, quin Phas. ohlongifolius 

 MiCHELi spec. nov. (»Contributions ä la flore du Paraguay», 

 1883 — 84, pag. 27, 28, tab. 6) idem sit ac Fhas. clitorioides 

 Mart.; flores quideni a cl. Micheli >-lutei» dicuntur, sed opinor, 

 eam rem in specimine sicco non plane distinctam esse, nec 

 quidquam a collectore, Balansa, de colore adnotatum est, 



Ph. truxilleusis H. B. K.

Huc sine ulla dubitatione pertinent collectionis Morongii 

 n:ri 198, 993, qui in opere »An Enumeration of the Plants 

 collected by Dr. Thomas Morong in Paraguay, 1888 — 1890, 

 by Th. Morong and N. L. Britton», sub »Phaseolo erythro- 

 lomate Mart.» afi'eruntur; mihi non visi sunt, sed ex verbis 

 collectoris: » — lateral petals — very dark reddish-]3urple»,
