Sonnet "Mayapple Flower"

[vagabond]

Beneath the twin umbrella leaves that fold              comma after leaves?   i get no meaning for twin umbrella.
with gentle curvature like praying hands,               "with gentle curves like faithful praying hands"?
hides a single flower, white and gold,
like shreds of linen in Egyptian sands -             "like shreds of linen, cast in egypt´s sands"..
i don´t quite see how the shreds of linen are similar to the white and golden flower (and why the flower is golden). why not substitute linen for some jewel (you introduced gem as a meta for the flower)
a mystery - the prelude to a treasure.                         "a mystery preluding to a treasure"
Approach its beauty like a priest in the night -             "...like a priest at night"
a priest who serves the doleful goddess Pleasure -
and kneel to see the blooming gold and white,      kneels
a living jewel fed by the ancient root,                       what kind of root? i d guess something like instincts . as was said before, "by an ancient root would sound better"
and shrouded by the two dark-spreading veils.    "and shrouded by two darkly spreading veils"
In time, the flower will become a fruit.                   "in time the flower will turn into a fruit"  (don´t know if flower can be pronounced as one syllable)
But it is dark, and you’ll  forget these trails         
(although you whisper now that you will not).
The blissful gem will ripen, fall, and rot.         

Please note that I am not trying for perfect iambic pentameter here. I'm focusing on five stresses, that's all.

made some suggestions for rhythm (to be considered with caution, since i m not a native english speaker).
i like that poem, but don´t get some of the images.
