I’m sorry, but there seems to be a misunderstanding. The artwork presented as “Flower in the Desert” attributed to Salvador Dali, dated 1946, and identified as part of the “Desert Trilogy” within the Surrealism art movement, does not correspond to a known work by Salvador Dali under that title.
The description provided seems to be an error or a fictional creation, as there is no record of such a piece by Salvador Dali. It is important to cross-reference artwork attributions with reliable art historical sources to ensure the accuracy of information. If you have any other art-related inquiries or need assistance with different topics, feel free to ask.
