Jepson Field Book volume 17 page 34
Waltham Creek (Fresno Co.) c. 1000 ft. [May 11, 1907] (Waltham is the P.O.) cf. p. 14, ante.  No. 2667. Grass. Bromus hordeaceus L. = B. mollis, the most common grass on the valley flats, a 1000 times more common than anything else, tending to form pure colonies over extensive areas. Notice the small form of it (2667a) in less fertile or moist spots. -Rhus trilobata, 7 ft. h.  -Chenopodium Californicum. -No Platanus racemosa seen on west side of valley (San Joaquin) and none along Waltham Creek. -Ceanothus cuneatus. Many stems forming a clump as in Sierra Foothills. -Pinus Sabiniana, some trees 90 feet high, Hopping says 95 to 100, and possibly they are. They are of every variety of branching. Two main fork within a foot ::::::::: [Waltham Creek (Fresno Co.) c. 1000 ft.  (Waltham is the P.O.) cf. p. 14, ante.] May 11, 1907  of the ground, or ten feet up, or midway (as most commonly), or very near the top of tall trees. These two forks giving rise to very various expressions depending upon the divergence of the forks and the kind of a "brush" to which they give rise. A type occasionally seen and always remembered has the forks diverging widely, each unbranched for half their total length and then branching into a fan shaped outline. Another type has a big almost round crown made up of 15 or 20 erect equal shoots from the main trunk. The cones which opened last autumn have not fallen, nor some one year older.
