    Notes

    Cenchrus spinifex Cav. Gr Thasos: Skala Rachoniou, at roadside, 6 m, 40°46'34"N, 24°36'15"E, 11.11.2016, Biel 16.022; W-NW of Rachoni, edge of dirt road, 30 m, 40°45'51"N, 24°37'07"E, 14.11.2016, Biel obs. New for Greece. On dampish ground at roadsides, late-flowering, with 15–30 individuals in full fruiting state. The large ‘burs’ (fascicles) are white villous pubescent and with a single, ca. 6 mm long, sessile spikelet within.

    The plants were previously identified as C. tribuloides L. (Biel & Tan 2016: 432); Cenchrus spinifex Cav. is even larger in all its floral parts (spines and spikelets) and the ‘burs’ are even more densely villous pubescent, but the species is not known to be weedy.
