5 Nasturtium philippianum Speg. Bol. Agr. Buenos Aires, 1: 200. 1901. 



6 It is doubtful whether this is distinct from H. falcaria. It ranges from 

 western Texas to southern Arizona and adjacent Mexico. H. falcaria is found 

 in southern South America. 



7 The relationship of this to P. juliflora, and the range of the latter species 

 are very uncertain. The Argentine plant may not be P. juliflora, but on the 

 other hand, P. glandulosa may not be sufficiently distinct from P. juliflora. The 

 same species, or else two closely related ones, occurs in Argentina and New Mexico. 



8 Euphorhia portulacoides L. Sp. PI. 456. 1753.
