Here is some information on the Abutilon species of the Llano Estacado.
BONAP

Abutilon fruticosum - Plants perennial; stems strictly upright; leaves gray, ovate, and dentate; mericarps 6-9. Primarily the eastern edge of the Llano Estacado.

Abutilon parvulum - Plants perennial; stems trailing or decumbent; leaves ovate, green, and coarsly dentate; mericarps 5. Relitively widespread in rocky limestone.

Abutilon theophrasti - Plants tall annual; stems strictly upright; leaves grayish, broadly ovate to suborbicular, and dentate; mericarps usually more than 10. Reported from Lynn Co. TX and Lea Co. NM.

Compared to the other US species A. wrightii and A. malacum occur relatively near the southwestern edge of the Llano but have not been documented in the region. Abutilon wrightii may occur in the limestone of the far SW edge around Ector, Winkler, and Andrews counties but further investigation is needed to confirm this.
