This glyph type was unquestionably associated with henua by Metoro. He may have meant something like 'the nourishing land'.

1. Perhaps this type of glyph is an image of a wooden staff (kouhau). Such were used in different circumstances: measuring, memory aids (cutting marks in the wood), sign of power etc.

"He [Eric Thompson] established that one sign, very common in the [Mayan] codices where it appears affixed to main signs, can be read as 'te' or 'che', 'tree' or 'wood', and as a numerical classifier in counts of periods of time, such as years, months, or days.

In Yucatec, you cannot for instance say 'ox haab' for 'three years', but must say 'ox-te haab', 'three-te years'. In modern dictionaries 'te' also means 'tree', and this other meaning for the sign was confirmed when Thompson found it in compounds accompanying pictures of trees in the Dresden Codex." (Coe)

The possible connection between a measuring staff and a numercial classifier for time periods made me early on in these studies conclude it was the origin of the glyph type henua. At tagata ('a fully grown season') I have therefore suggested that henua glyphs (here below Eb3-3 and Eb5-6) were used in the meaning 'season', 'period', etc:

'winter' (from autumn to spring equinox)
'summer' (from spring to autumn equinox)

The step from a numerical classifier for time periods to a rongorongo glyph type designed like a staff and used for indicating time periods appeared short. It could explain the henua sign in the end-of-period glyphs in such calendar texts as for instance:

7
	Ga4-1	Ga4-2	Ga4-3	Ga4-4

Here the preceding henua (Ga4-3), we have seen (cfr haga rave), indicates the beginning of summer. Period 7 tells about the time when winter gives way to summer.
