This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
虂 is a rare character composed of 艹 (grass) on top and 露 (dew) below. The exact historical development is uncertain, but it likely relates to dew on plants.
With grass 艹 above and dew 露 below, imagine morning dew settling on grass blades, but the kanji itself has no established meaning.
For ロ, picture a low-growing plant covered in dew: low -> ロ, and the grass radical 艹 sits above the dew component 露.
