I have been cautious in referring to the fynonyma of authors on this plant, feeing they differ fo much 
in their opinions refpedting it; and have rather wifhed that the plate here given, might ferve as a recon- 
ciliatory reference. Linnaus and Haller both feem to doubt its being a fpecies diftindt from th & album, 
and it muft be confefled there is a great fimilarity betwixt them ; yet if my obfervations are juft, there is 
every reafon to conlider them as two plants perfectly diftindt. 
They agree in this, that they are both annual plants, both grow In the fame foil and fituations, are nearly 
alike in their fize and habit, and both flower about the fame time; and yet they differ in many refpedls 
very eflentially. That which in a more ftriking manner diftinguifhes the viride from the album , is the gteener 
appearance of the whole plant, the bright red colour at the angles of the joints, which is conftant, and the 
lhape of the leaf, fig. 1, which is always much longer than that of the album. The album is loaded with an 
appearance of meal, which gives it its white colour ; the viride , though not deftitute of it, has it not in that 
profufion. When the feed are ripe, the tops of the ftalks, in the viride , are more apt to hang down ; the 
parts of the frudtification, fig. 1, 3, 4, 5, are very fimilar, but fmaller; and the calyx is not quite fo much 
covered with little globules : the feeds of each differs very confiderably, and affords a very curious and fatif- 
fadtory diftindtion : in the album it is perfe&ly fmooth, glaber ; in the viride it is fmaller, and reticulated with 
impreffed dots, reticulatus pun diis imprejjis , fig. 6. 
Like fome of the other fpecies of this Genus it is eaten as a pot-herb.
