NAMA, L. 



The outlines of a monograph of this genus which, in the year 1861, 

 I contributed to the Proceedings of this Academy (vol. 5, pp. 337-339) 

 have long needed some corrections and additions. The following notes 

 for a revision of the genus were mainly drawn up in the Kew Herba- 

 rium, in October, 18G9. 



§ 1. Folia in caulem alato-decurrentia, obovata vel spathulata, pube 

 moll i villosa seu pilosa : rami procumbentes. 



N. Jamaicensis, L. Pedunculi brevissimi. Semina costato-scro- 

 biculata. 



N. biflora, Choisy. Pedunculi filiformes. Semina alveolata. — 

 Mexico, collected only by Berlandier. 



§ 2. Folia caulina omnia vel plera basi subamplexicauli sessilia, 

 baud decurrentia, pube molli nee incana. Annua?.
