On this, the main page, the posts have been arranged in reverse chronological order — most recent first. In the right-most column are categories by family, and by genus under each family.
The main page has thumbnails. To view a larger image, click on the thumbnail. From there, you may click on a link to get an even larger image.
To view links to plants by plant family or genus, click on the Category in the right-hand column. (If a family or genus name appears there, then there are photos/entries for some species of that family and/or genus.) That will take you to a list of posts of plant species; click on the desired species, and you will be taken to the full photo entry for that species.
Comments are welcome, including if you disagree with my identification. Plants shown are from Lassen County and/or the Lassen National Forest and/or the Lassen Volcanic National Park, no other areas. Of course, many of these species will be found in other areas.
Prints or digital downloads (without my logo) may be purchased: contact orrin.winton at gmail.com for information. The originals of these photos are most often much bigger (in bytes) than what is displayed here, because this site limits me to uploading 8MB per image. Photos with a more varied content can be found at orrinwintonphotography.com.
