Physorrhynchus chamaerapistrum (Boiss.) Boiss.

Aucher Eloy 4146, without mature fruits from S. Iran, was included under Physorrhynchus brahuicus by Boissier (l.c.) but O.E. Schulz (l.c.) included it under Physorrhynchus chamaerap¬istrum. This shows how difficult it is to separate the two species. The former species generally prefers stony and rocky habitat while the latter is found in sandy plateau.

Indistinguishable from the above species in habit and appearance but has only 2 ovules, one in each locule of the ovary, and the basal part of the fruit short and subtriangular, often inconspicuous.

Distribution: Iran and Pakistan.

Fl.Per. April-May.
