The highlighted words are hyper-links that send you off to other pages. This web site has about 3200 pages organized into at least 5 levels. Move through the hyperlinks (usually blue text with underlining)to the next level. The hyper-links can be , text, boxes, or mapped pictures. Content in the form of pictures and information is what the web is about. We've moved from a printed catalog to the web because of customer requests for pictures. Trying to update the 'Manual of California Native Plants' killed 3 computers. The 1000 images made up a 100+ meg file.(It's now ten times bigger.) It is a whole lot easier and cheaper to give you full content on the web.
Set your display to a reasonable setting. If you have a mondern monitor and computer that is at least 1600X1200, ask someone to help you if your monitor is set at 800X600. You're already probably half blind for the monitor.
