In the view of Humberto Garch, general secretary of TEPAL, the Panama-based pan-regional TV association, "In Argentina, regulators will not allow Telcos to buy up cable TV companies and create monopolies or duopolies, as was the case in Mexico, Colombia and Brazil."
What looks like the subtending bract is in reality the outer median tepal. Among Alismatales, many Araceae (including Lemnaceae) have unicarpellate flowers (also the basal genus Gymnostachys; Buzgo, 2001), and some have unistaminate flowers (Mayo et al., 1997, 1998; Landolt, 1998).

(2004) has reported that an active alkaloid 'Narciclasine' from Narcissus (daffodil) delayed the tepal senescence of cut iris flowers by inhibiting protein synthesis, thereby leading to the same conclusion.
We concluded that, in the helobial monocotyledons as a whole, inflorescence bracts, sepals, and tepals are homologous structures derived from the phyllomic appendages of the original multiaxial reproductive structure and, therefore, that the divergence between the petaloid and tepaloid groups involved divergence of the relationships between phyllome and subtended structure, at the same time as the axes of the original multiaxial structure became differentiated into "flower" and "inflorescence." Finally, in a number of helobial families (e.g., Najadaceae, Cymodoceaceae, and Zannichelliaceae) reproductive structures are so reduced that morphological approaches to patterns of evolution founder for lack of information.
They may represent tepals, staminodes, stipules, ligules, reduced bracts, leaves, branch systems, or novel structures (Clifford, 1987).
It has up to 15 pure white or pink-flushed tepals - a combination of petals and the flower shields or sepals.

Hedyosmum differs in having three tepals adnate to the ovary, which is therefore inferior; the female flowers are borne in thyrses of monochasial cymes in the axils of bracts, whereas the male flowers are single stamens borne in spikes with no subtending bracts.
