GYMNOSPERMS ON STANFORD GROUNDS ABRAMS 103 



Frequently planted on the University grounds but enduring badly in the dry 

 soil. Native trees are on the estate along San Francisquito Creek. A notable 

 individual is the "Palo Alto" at the railway bridge between Palo Alto and 

 Menlo Park. 



2. Sequoia Washingtoniana Sudw. Giant Sequoia. 



Leaves scale-like, arising from all sides of the branchlets, y%- l / inch 

 long, glaucous green; cone ovate-oblong, 2-3^2 inches long. 



The Giant Sequoia is the largest and probably the oldest of trees. It 

 is 200-325 feet high and attains a diameter of 30 feet. Native of the western 

 slopes of the Sierra Nevada, where it usually occurs in small, isolated groves, 

 but it forms rather extensive forests in the basins of the Tulare, Kings 

 and Kaweah rivers. Frequently planted on the University grounds, and 

 apparently better adapted to our local climate and soil than the Redwood. 



8. Cryptomeria. 



Pyramidal tree with reddish brown bark. Leaves linear-subulate, aris- 

 ing from all sides of the twigs, decurrent. Flowers small, monoecious ; stami- 

 nate oblong; pistillate globose. Cones globose, with thick, wedge-shaped 

 scales furnished with a recurved projection on the back and pointed lobes at 

 the apex. 



A monotypic Japanese genus. 



1. Cryptomeria japonica Don. 



Leaves compressed, somewhat incurved, y 2 -\ inch long; cones reddish 

 brown. 



A handsome evergreen tree extensively planted in Japan, especially about 

 temples. A few trees are planted on the University grounds, but it does not 

 thrive in our dry soil. An excellent specimen is at 9 Lasuen St. 



la. Cryptomeria japonica elegans Beissn. 



Low dense tree or shrub, with horizontal branches and pendulous 

 branchlets; leaves linear, flattened, soft, bright green changing to bronze in 

 winter. 



A garden form. Good specimens are on the grounds of the Stanford 

 Residence. 



9. Taxodium. 



Tall, deciduous or evergreen trees, with cinnamon brown, flaky bark. 

 Leaves linear, 2-ranked, falling off in the autumn or the second year with the 

 short slender lateral twigs ; flowers monoecious, the staminate with 4-5 pollen- 

 sacs to each anther, the pistillate solitary or in pairs at the ends of the branch-
