 1. Voyria (Leiphaimos) cMonea; caule filiformi simplici unifloro v. 

 subramoso paucifloro, calyce breviter 5-fido laciniis acutis, coroUse 

 nivese hypocraterimorphse tubo gracili laciniis oblongis acutiusculis 

 vix duplo longiore. — Species multo gracilior quara V. tmiflora, Ge- 

 . nitalia fere hujus speciei, sed corollse tubus dimidio brevior, laciniae 

 paullo majores et minus acutatre, et color niveus. 

 Gathered by Mr. Spruce in forests on the Rio Negro, near Barra, in

 phse lobis 5 lineari-subulatis recurvis, filamentis versus apicem tubi 

 brevibus, antheris subconnatis brevibus latis. — Habitus squarase et 

 coroUae tubus F". uniflor{B, sed laciniis angustissimis 3-5 lin. longis 

 insignis. AntJierce latiores quam longse, basiin filamentum fere cune- 

 atae. Stigma peltato-capitatum. JTor^s pallide flavi.

 ampliato, laciniEC 4-6 lin. longae, lanceolatse, acutissima?, supra basin 

 nonnunquam minute papillosse. Antherce oblongse, loculis inter se 

 discretis sed cum anthera contigua connatis, apice obtnsis, baai in
