Natural History Wanderings

Submitted by  Tom Hilton

Went to Ring Mountain Saturday. No Calochortus tiburonensis blooming yet (it was a longshot, with the late spring we’ve had), but there’s plenty to see at Ring Mountain. Lots of Tidytips, Tarweed, and Ithuriel’s Spear. Pitted Onion is at its peak, whole fields of it up in the serpentine barrens. Here’s a list of what I saw in bloom (link to photos at the end): Allium lacunosum var. lacunosum Allium unifolium Castilleja affinis ssp. neglecta (CNPS 1.b.2) Castilleja rubicundula Collinsia heterophylla Delphinium hesperium Dichelostemma sp. Eriogonum nudum Hemizonia sp. Hesperolinon congestum (CNPS 1.b.1) Layia platyglossa Phacelia sp. Silene californica Sisyrinchium bellum Thermopsis sp. Triteleia hyacinthina Triteleia laxahttp://www.flickr.com/photos/tomhilton/archives/date-taken/2011/05/21/
