Vintage Botanical Illustration Generator

Improved prompt:

Design a detailed botanical diagram of a ${subject}, modeled after the illustrations found in late 19th century scientific journals. The diagram should feature:

1. Accurate and lifelike rendering of the subject's morphology, including all relevant structural components such as leaves, stems, flowers, and fruits.

2. A muted, natural color palette inspired by sepia toned photographs, emphasizing earthy browns, greens, and tans. Avoid vivid or artificial hues.

3. Cross-sectional views or cut-away illustrations highlighting internal structures, labeled with appropriate anatomical terms.

4. Hand-drawn annotations rendered in a style reminiscent of 19th century ink pens, using slanted, flowing scripts. Use sepia tone for the ink.

5. An overall composition that mimics the layout of a vintage scientific plate, with a border, title, and margin space for the handwriting.

6. Ensure the diagram is sufficiently detailed to be educational and informative, yet visually appealing with a focus on aesthetic clarity.

7. Maintain a consistent scale and proportion throughout the illustration, with key features and structures clearly distinguished.

8. Avoid modern or digital graphic elements; the style should be utterly authentic to the pre-20th century scientific illustration aesthetic.

Please provide the diagram as a high-resolution vector or raster image file, suitable for printing or detailed digital inspection. The subject should be a plant species from the ${category} group.
