**Key Considerations when choosing an option:**

* **Target audience:** Who are you writing for? Knowledgeable botanists or general enthusiasts?
* **Content context:** Is this a general website about plants, or does it have a specific focus?
* **SEO:** Do you want to include keywords related to plant classification for search engine optimization? (e.g., 科屬, 物種, 命名)
* **Website goals:** What do you want users to do when they read the description? (e.g., browse articles, gain knowledge)

I recommend choosing an option that best reflects the content and purpose of your blog or website, and tailor it to your specific needs. Remember to be relatively concise in the description, allowing the title to be the main information carrier.
