This is a polymorphic but clearly outlined species. Attempts to segregate eastern forms as a separate species,
Ceratocarpus turkestanicus (
C.
utriculosus), were based on minor, variable, and non-correlated characters, such as branching habit, broader vs. narrower leaves, obovoid vs. trigonous fruiting bractlets, etc.
The plant is a common ephemeral in deserts.

C.turkestanica Sav.-Rycz. (in Kom., 1.c. 874) was said to differ by its broader leaves 15-50 x 2-10 mm, linear-oblong, and obovoid bracteoles 5-10 (-15) x 4-7 mm. Some of our specimens cited above (collected by S.Kitamura from Quetta and S.I.Ali from Murree) are very similar to this. These variations may be due to age or habitat.

Description
provided by eFloras
Annual, greyish herb with stellate-dendroid hairs, up to 30 cm high, branched from the base, the alternate forking branches often giving it a spherical tumble-weed shape; stem and branches stellate and long hairy, densely so in the lower parts. Leaves alternate, opposite or in whorls of 3 at the crotches, linear-filiform to linear, entire cuspidate, 1-nerved, lower 5-25 (-50) x 2-5 (-10) mm with a short mucro; upper leaves or female bracts much narrower, ± long cuspidate, covered with stellate hairs, long unbranched jointed hairs sometimes arising from the centre of the stellate hairs. Perianth of staminate flowers oblong-ovate, with obtuse lobes, sparsely covered with fugacious stellate hairs. Ovary densely stellate-hairy, hidden within bracteoles. Fruiting bracteoles oblong-obcuneate, (3.5-) 5-7 x 2.5-4 mm, with a longitudinal nerve on each side and with straight spreading subulate spines, up to 5 mm long, at the margins and apex.
