The two first ential are prostrate branching herbs with a 
stout root. In the Sudan a blue dye is obtained from the capsules. 
The stems yield a strong fibre which is not easily separable 
(Broun). Both the seeds and the leaves have purgative properties. 
All three varieties occur on river banks and on sandbanks in 
river beds. The two prostrate varieties occur also in depressions, 
more especially in cotton soil; the second variety is, besides, a 
common weed of cultivated ground and palm groves 
The specimens of the typical plant collected by Clive and 
Bruguiére which have been localised as from Syria have no 
original field-note. The same is the case with the specimens of 
p. ee re obtained by the same collectors, which have been 
localised as from Egypt. It is therefore permissible to conjecture 
that some error has taken place with regard to the Syrian habitat. 
This conjecture is not, however, necessarily correct because it 
has recently been ascertained that typical C. plicata does occur 
now, near Jerusalem, perhaps as a recent introduction. In the 
Limpopo lecality, which is close to the Tropic of Capricorn, the 
species is plentiful, but only the third variety, Dr. Beijer informs 
us, is to be met with there. The statement relied upon in 1912 
that the petalsin $8. obliquifolia may be yellow (Fl. Trop. Afr. 
vi. 1. p. 835) appears to i incorrect; they are pink, as in a. typrca 
and in y. erecta. The statement that the plant is not tinctorial 
(Pflanzenr. IV. 147. vi. p. 18), though correct as regards the two 
Indian species there merged in C. plicata, does not apply to any 
of the forms of C. plicata itself.
