It is a runner. Flower heads seem globular rather than cylindrical, 5 mm across, flower colour could be orange or reddish but I do not remember. The leaves are less than 15 mm long. It was collected from an arid place in Symi island (SE Aegean Sea).
I have found a Phyla monograph. This specimen looks like Phyla nodiflora var reptans (today Phyla x reptans). Compare with another my Phyla (see link below) which seems to be pure Ph. nodiflora var. nodiflora.
Thank you. I studied the attached publication more closely and they write that Ph. x. reptans is reported only from the New World. So, my both specimens differ due to their development stage or the Ph. nodiflora is so variable. Thank you once more for your valuable help. Best regards.
