In or about the edges of the chotts, which are the leading
topographical features of the region immediately south of Touggourt,
the most common species are _Haloxylon_ sp., _Salsola tetragona_,
_Limoniastrum guyonianum_, and _Arabis aphyla_. Besides these forms,
about 28 kilometers south of Touggourt fine specimens of _Halocnemon
strobilaceum_ were seen growing in an extremely salty situation,
to the total exclusion of other species. _Tamarix_ also is to be
found in and about salt spots near Touggourt. (See fig. 64.)

Both Massart and Doumet-Adanson (Bull. Soc. Bot. France, 39, 1892)
have discussed the flora of the Touggourt-Ouargla region. The
following exhaustive list is given by the latter author as having
been collected between the two desert towns:

  Henophyton deserti.
  Matthiola livida.
  Malcolmia ægyptica var. linearis.
  Moricandia cinerea.
  Sisymbrium pendulum.
  Savignya longistyla.
  Reseda stricta.
  R. arabica.
  Helianthemum sessiliflorum.
  H. ellipticum.
  Randonia africana.
