Except for the first phrase (on which see next note), this entry is equivalent to Lexica Segueriana 216.26 Bachmann, and is also very similar to Lexicon in Orationes Gregorii Nazianzeni tau187. See also epsilon 769, epsilon 820.
[1] The adjective translated here as "overgrown" (di/ulon) is attested only here and in the corresponding passage in the Lexica Segueriana. I have translated it as if it were derived from u(/lh ('wood', 'vegetation'), but that is somewhat questionable as the Lexica Segueriana has di/ulos to/pos h)\ dasu/s ("a place that is diulos or overgrown"). For this meaning for the headword, distinct from its normal meaning of 'marsh', see also Hesychius epsilon2871, Etymologicum Gudianum epsilon415.
[2] This translation treats the genitive phlou= ('mud') as an object of the participle e)pikexume/nou ('spread over'), though normally one would expect a dative in that position. It would be more natural to take 'mud' as the subject of the participle, but that would leave no clear role for u(/datos ('water'). For what it is worth, the Lexicon to Gregory of Nazianzus (see primary note above) omits the word for 'mud' here, and 'water' is clearly the subject of the preposition.
