because of the similar leaves and the pubescent exterior of the corolla, but is readily distinguished by the distinctive ovate sepals with truncate base and long attenuate apex. Additionally the inflorescence is of elongate complex cymes, somewhat racemose in form and with distinctive persistent linear-lanceolate bracteoles. The form of the inflorescence (axillary cymes) combined with the oblong leaf shape strongly suggests this is essentially a decumbent species even though this is not indicated in field notes.
