That Melilotus

The Melilot from Lower Breakish has survived well in water and continues to develop:

I noted these long stipules

and looking at the illustrations by Sybil Roles that accompanied Clapham, Tutin & Warburg (1965) this clearly suggested Melilotus altissimus (Tall Melilot).

However, more modern floras do not mention the stipules except that Sell & Murrell say for M. altissimus stipules 5-6mm, subulate, dentate at base and for M. officinalis stipules 5-7mm, subulate, dentate at base. Hmm… not much difference there and if anything the length on my plant suggests M. officinalis.

The fruits are developing but not yet ripe. However, the calyx is hairy as in M. altissimus (though not very) and the fruit shows no sign of the ribs typical of M. officinalis

Oh, and there appear to be two seeds per fruit, typical of M. altissimus:

and the flowers seem to have the keel ± equalling the wings, again a feature of M. altissimus (Tall Melilot). So that is my current conclusion, though it will be good to check mature fruits which should be black rather than brown when mature.
