These lines mean that some of the bangles are shining as the new born leaves, whose freshness is closed (compared) to the vivid (clear) beauty of the tender leaves, expressing their tender desires.
Some are aglow with the bloom that cleaves
To the limpid glory of new born leaves. (lines 11-12)
In the above lines the poet compares the shiny green bangles to the transparent beauty (limpid glory) of the light green, new born leaves.
The new born leaves shine with the bloom (a delicate powdery surface deposit) that cleaves (adheres or sticks) to those leaves. The green bangles are shining the same way, as the poet describes them. These bangles symbolize the tender nature of a maiden girl.
The phrase “limpid glory of newborn leaves” is an ideal way of describing the light green coloured bangles worn by young maidens. The bangles reflect the same joy, tranquility and satisfaction which is seen in the beautiful and delicate new born leaves which seem pleased with themselves due to their bright green colour which radiates vibes of joy and happiness.
