=- This plant is so well known, that it needs no particular 
. description : all that is worthy of mention is the structure of

 Carpels are all perfected into an equal number of 1-seeded 
 drupes ; I have observed sometimes in the above species, 
though it rarely happens, that 2—3 nuts are combined into 
one, which is then 2—3 celled, each cell having a single seed. 
In habit it approaches the typical genus Nolana. The nut is 
Unequally angular, rhomboidal, sharp-angular, of a spongy co- 
_ Maceous consistence, the place of its basal attachment being 
Marked by a small round cicatrice, being the area of a hard cy- 
lindrieal operculum that closes the channel leading into the 
included cell. The seed which fills the cavity is reniform and 
Compressed, the {esta is yellow, reticulate, and crisp, the inner 
integument is a very thin transparent membrane enclosing 
the albumen, which is white, hard and fleshy; the embryo is 
white, filiform, bent in a somewhat spiral form, the radicle 
_ Pointing towards the hilum, or inner aperture of the cell : the 
. cotyledons, which together are somewhat more slender than 
the radicle, are about the same length.*
