The plant seems so wholly given to reproduction that little attention 
is paid to the development of the individual. The old trees are not 
without foliage but their annual increment in height, or spread, to 
say nothing of trunk diameter, must be very small indeed. Where the 
young saplings are crowded they still .bloom altho the inflorescence is 
less conspicuous. In short, the plant is a typical xerophyte. 
The two species may be now thus conpared: 
Distribution 
Cupressus macrocarpa. 
Sea-coast by the mouth of 
Carmel river only. 
Cupressus goveniana. 
Small area at Monterey, 
two or three miles from 
the sea also reported on 
dry plains, Cape Mendo- 
cino. 
Habitat 
Immediately over looking 
the sea; along the water 
edge; grove 20 rods in 
width at widest, gener- 
ally much less. Soil gen- 
erally rich, in places ex- 
tremely fertile and cal- 
careous ; average altitude 
about 50 ft. 
Dry western sun-burned 
slope; soil thin, decom- 
posing granite. Altitude 
near 500 ft. ; occupying 
but a few square rods. 
Meteorologie 
condition's 
Annual rainfall supple- 
mented by evaporation 
from the sea: fogs at all 
seasons, in dry season es- 
pecially relieving 
drought. 
Annual rainfall almost the 
only water supply; fogs 
rendered much less effi- 
cient by reason of situ- 
ation. 
Morphology 
Large trees; stunted speci- 
mens; the best 125 ft. in 
height, the largest seven 
feet in diameter. 
Small trees; shrubby; the 
largest 15 to 20 feet in 
height. 
Inflorescence 
Less abundant; few trees 
in bloom, Feb. 8, 1913. 
Abundant, exhaustive, 
tending to dioecism (?), 
Feb. 1, 1913. 
Fruit 
Not abundant; the cones 
scattered or in dense 
clusters; when clustered, 
often proportionately 
smaller. 
Very abundant; cones gen- 
erally clustered ; when 
isolated proportionately 
larger.
