156 ERYTHEA. 
About three miles from Manzana is a small sheet of water, 
Lake Catrina, the road to which is well defined and botani- 
cally very interesting. As we entered the foothills the first 
shrub encountered was the wild almond, Prunus fasciculata, 
Gray. Gilia Parrye, Gray, and G. dichotoma, Benth., are 
here abundant. Throughout the day the latter can scarcely 
be observed, its convoluted tube being tightly closed, is 
inconspicuous; but at five in the afternoon all is changed. 
The plants of Gilia Parry, that all day sparkled like 
daisies in the sun, have closed, and in the space of ten or 
fifteen minutes, Gilia dichotoma has unrolled its petals and 
filled the air with sweet fragrance. With the appearance of 
the morning sun Gilia dichotoma goes to sleep again, and 
Gilia Parrye opens. A few specimens of Collinsia Childsii, 
Parry, gathered here had such congested branches as to 
appear new to me, but Dr. Robinson of Harvard, who 
examined them, informs me that the same form was gathered 
by the Death Valley explorers. Peucedanum dasycarpum, 
T. & G., and P. Parishii, C. & R., were plentiful and in the 
shade of the pine trees, further on, Leptotenia multifida, 
Nutt., was coming into flower. Chcenactis Fremonti, Gray, 
C. stevioides, H. & A., C. Xantiana, Gray (the two latter 
rare), with Viola premorsa, Dougl., and Arabis pulchra, 
M. Jones, were here observed. 
On the heights near the shore of the lake Thermopsis Cali- 
fornica, Wats., was growing, while around the water were a 
number of willows which presented a curious appearance on 
account of the long rootlets hanging from their branches six 
feet up, the result of a long continued overflow of water 
about six years ago. 
Entering a cafion south of this, and passing over a high 
ridge into King’s .Cafion, gave us an opportunity of seeing 
Some new shrubs. In the bottom of the watercourses and in 
King’s Cafion a few trees of Asculus Califormca, Nutt., 
were found; doubtless they are to be found in all the moist 
cations of the range. The pine trees here (alt. 3,500 ft.) are 
all Pinus Sabiniana, Dougl., while farther westwards P.
