Box.— Vol. I.] EASTWOOD—STUDIES FROM THE HERBARIUM. 1 27 



February 20th, it was seen in bloom every Sunday. Well 

 formed fruit was observed on the bushes on the Throck- 

 morton Trail before those on the higher West Point Trail 

 had ceased blooming. Some plants only a few inches high, 

 easily pulled up by the roots, and with but one or two 

 branches, were laden with blossoms. The number of these 

 small plants indicates a species full of vigor, seeking new 

 territory for habitation. The roots of the larger plants are 

 spreading rather than deep and are easily pulled up. Dur- 

 ing May the berries become ripe, and before the other spe- 

 cies show ripe fruit this has usually lost all its berries. 



3. Arctostaphylos glandulosa Eastwood. — On Decem- 

 ber 19th the first plant of this species was found in bloom. 

 It may have been blooming also elsewhere on the mountain; 

 but two weeks earlier flowers were not seen on the plants 

 near the foot of the Boot-jack Trail, where I have always 

 found them first in bloom. On May ist, fully grown fruit 

 was observed on bushes on the Boot-jack Trail. This 

 species is the most abundant, found everywhere on the 

 slopes and ridges of Mt. Tamalpais and the Fairfax hills. I 

 am still uncertain whether two species ought to be recog- 

 nized where I have described but one or whether, with all 

 its forms, it ought not to be considered a variety of A, 

 tomentosa. 



4. Arctostaphylos montana Eastwood. — This has a 

 wide range in Marin County. It is usually found only on 

 the uplands and is especially partial to the bluish gray vol- 

 canic areas. Wherever Cupressus Goveniana and ^uercus 

 dumosa var. bullata are to be found this also will be seen. 

 Besides Mt. Tamalpais, it is found on the Fairfax hills, 

 where it covers large sections of country, being the most 

 abundant manzanita there. It was first seen in flower 

 February twenty-second, on the trail to the source of the 

 Big Carson. Only one bush was in bloom, situated in a 

 warm and sheltered spot. On May ist it was still blooming
