150. Convolvulus elymaiticus Mozaff., Iranian J. Bot. 16: 206. 2010. (Mozaffarian 2010: 206).

Type.

IRAN, Ilam, Mozaffarian 88391 (holotype TARI).

Description.

Very similar to Convolvulus commutatus differing in the indumentum of long spreading hairs and the inflorescence with rather loose heads, arising at both the apex of the stem and in the upper 3 leaf axils.

Distribution.

Endemic to Iran and only known from the type collection.

Notes.

Convolvulus elymaiticus appears to lie between Convolvulus commutatus and Convolvulus calvertii . The lax inflorescence, white corolla and geographical distribution suggest an affinity with Convolvulus commutatus while the corolla size (2 cm long) places it in intermediate position. The spreading hairs on the stem, however suggest a closer affinity with Convolvulus calvertii and the presence of individual flowers in the uppermost leaf axils, which also occurs occasionally in Convolvulus calvertii , confirms this. Without seeing material it is impossible to be certain whether this is a good species or not but it seems likely to be a form of the variable Convolvulus calvertii .
