Family Cupressaceae

Trees or shrubs evergreen , monoecious or dioecious. Leaves decussate or in whorls of 3, scalelike and then often dimorphic with flattened facial leaves and keeled lateral leaves, or needlelike particularly in juvenile plants , often with an abaxial resin gland . Pollen cones terminal or axillary , solitary, maturing and shed annually; microsporophylls 6-16, decussate or whorled , each bearing (2 or) 3-6(-9) pollen sacs ; pollen wingless. Seed cones usually terminal, solitary, globose , ovoid , or oblong , dehiscent or indehiscent when mature in 1st or 2nd(or 3rd) year; cone scales developing after ovules originate in bract axils; bracts almost completely enveloped by cone scales, free only at apex; ovules 1-numerous per bract axil, erect ; cone scales of mature cones 3-16, flat or peltate, woody, leathery, or succulent, 1-20-seeded. Seeds winged or not; wings derived from seed coat . Cotyledons usually 2, rarely 3-6. Germination epigeal.

Nineteen genera and ca. 125 species: worldwide; eight genera (one introduced ) and 46 species (16 endemic, 13 introduced) in China.[1]

Tribe Senecioneae

The Senecioneae are a tribe of closely related genera that can be recognized most readily by the nature of the pappus and the involucral bracts or phyllaries. The phyllaries are basically in one well developed, often partially or wholly connate series of equal length that closely envelope the head . Frequently there are a few, very much smaller and mostly randomly distributed, often necrotic-tipped bracts near the base of the main series. The pappus is of fine, soft, often pure white capillary hairs . Heads may be either discoid or radiate . -- Gerald Carr.

Genus Sequoia

Trees giant, evergreen . Branchlets terete , with obvious annual growth constrictions. Leaves alternate, mostly in 2 ranks . Adult leaves linear or linear-lanceolate to deltate, generally flattened, divergent to strongly appressed ; abaxial glands absent. Pollen cones with 6--12 sporophylls, each sporophyll with 2--6 pollen sacs . Seed cones maturing and opening in 1 season , oblong to globose ; scales persistent , 15--30, valvate , ± peltate, thick and woody. Seeds 2--7 per scale, lenticular , narrowly 2-winged; cotyledons 2(--4). x = 11.[2]

Physical Description

Species Sequoia sempervirens

Trees to ca. 110 m ; trunk to 9 m diam.; crown conic and monopodial when young, narrowed conic in age. Bark reddish brown, to ca. 35 cm thick, fibrous , ridged and furrowed . Branches downward sweeping to slightly ascending . Leaves 1--30 mm, generally with stomates on both surfaces, the free portion to 30 mm, those on leaders , ascending branchlets , and fertile shoots divergent to strongly appressed , short-lanceolate to deltate, those on horizontally spreading to drooping branchlets mostly linear to linear-lanceolate, divergent and in 2 ranks , with 2 prominent , white abaxial stomatal bands . Pollen cones nearly globose to ovoid , 2--5 mm, borne singly on short terminal or axillary stalks . Seed cones 1.3--3.5 cm. Seeds flattened, 3--6 mm, leathery. 2 n = 66. [source]

Redwood is the only naturally occurring hexaploid conifer. It is one of only a few vegetatively reproducing conifers (from stump sprouts) and possibly the tallest tree species known. Winter buds , though small, are evident. [source]
