NOTES ON THE FLORA OF MARIN COUNTY, CALIFORNIA. 73 



Throckmorton Trail and a few are quite accessible. It has also 

 been reported from near Corte Madera by Miss Belle Brown, 

 (Zoe, ii. 77); Miss M. E. Parsons, also, has found it there. It was 

 recently seen in the Blithdale Ravine by Mrs. M. L. O'Neil. The 

 little boys at Mill Valley who sell bunches of it to the Sunday 

 visitors probably know of other localities. 



Rhododendron occidentale can probably be found in bloom on 

 the hills of Marin County during every month of the year. There 

 are two places, where it was frequently seen by the writer during the 

 past November, December, January, February, and March. One 

 is on the trail to the head of the Big Carson on the hills back of 

 Fairfax, the other a spot on the Boot-jack Trail. During the 

 winter the flowers appear on the dry leafless branches, reminding 

 one of the legendary flowering of St. Joseph's Lily. Sometimes 

 they are surrounded by brilliant scarlet leaves, which persist into 

 the winter. It is most attractive, then, and always suggests old 

 age with a youthful heart. My record shows it to have been 

 observed in bloom on the following days: Nov. 21, Nov. 28, Dec. 5, 

 Dec. 12, Dec. 26, Jan. 16, Feb. 26, March 13. 



Pyrola aphylla has been seen by the writer in Cataract Gulch, 

 west- fork of Sequoia Canon and near Mason's Camp on Lagunitas- 

 Creek. Itisrare y aud only one or two plants have been noted in 

 each locality. 



Cornus Nuttallii has been vaguely reported from Marin County; 

 but so far as known, no record of any definite locality, no collection 

 of specimens has ever been made from that county. On May 1, 

 while on a tramp over Mt. Tamalpais from Rock Spring to the foot 

 of Cataract- Gulch, it was seen by the writer for the first time, in all 

 the glory of its mantle of snowy flowers. It was a sight never to 

 be forgotten, forever inspiring and uplifting in remembrance. The 

 tree grows along the banks of the stream, that further down tumbles 

 over precipitous rocks, through the most picturesque canon on 

 the mountain, forming the main branch of Lagunitas-Creek. 



It was no mean specimen, but a tree probably fifty feet in height 

 with a slender trunk about six feet from the ground to the lowest 

 branches. The tree was a canopy of flowers, marvelous and start- 

 ling to look upon. The individual clusters ranged from five to eight
