ntal branches and drooping branchlets, has
the leaves but slightly spreading from the stems, especially when young.
Very beautiful; hardy as far north as Massachusetts.

GENUS =102. SEQUOIA.=

Flowers monoecious, terminal, solitary, catkins nearly globular. Seeds
winged, 3 to 5 under each scale.

[Illustration: S. gigantea.]

1. =Sequoia gigantea=, Torr. (BIG OR GREAT TREE OF CALIFORNIA.) Leaves
on the young shoots spreading, needle-shaped, sharp-pointed, scattered
spirally around the branchlets; finally scale-shaped, overlapping,
mostly appressed, with generally an acute apex, light green in color.
Cones oval, 2 to 3 in. long, of about 25 scales. The largest tree known,
300 ft. high, with a trunk nearly 30 ft. through, found in California
and occasionally planted east, though with no great success, as it is
almost certain to die after a few years.

2. =Sequoia sempervirens=, Endl. (REDWOOD.) Leaves from 1/2 to 1 in. long,
linear, smooth, 2-ranked, flat, acute, dark shining green, glaucous
beneath; branches numerous, horizontal, spreading. Cones 1 in. long,
roundish, solitary, terminal; scales numerous, thick, rough, furnished
with an obtuse point. A magnificent tree from California, where it grows
200 to 300 ft. high. In the East it can be kept alive but a few years
even at Washington.

GENUS =103. THUYA.= (ARBOR-VITAE.)

Small, evergreen trees with flat, 2-ranked, fan-like spray and closely
overlapping, small, appressed leaves of two shapes on different
branchlets, one awl-shaped and acute, the other scale-like, usually
blunt and close to the branch. Fertile catkins of few, overlapping
scales fixed by the base; at maturity, dry and spreading. There are
scores of named varieties of Arbor-vitae sold by the nurserymen under 3
different generic names, Thuya, Biota, and Thuyopsis. There are but
slight differences in these groups, and they will in this work be placed
together under Thuya. Some that in popular language might well be called
Arbor-vitae (the Retinosporas) will, because of the character of the
fruit, be included in the next genus.

* Scales of the cones pointless, thin, straight. (Thuya) 1, 2.

* Scales reflexed and wedge-shaped. (Thuyopsis) 3.

* Scales thick, with horn-like tips. (Biota) 4.
