=JJ.= Leaves hardly evergreen; spray quite slender. (=ZZ.=) =JJ.= Leaves fully evergreen. (=KK.=) =KK.= Leaves awl or scale shaped, and mainly appressed to the stem. (=WW.=) =KK.= Leaves linear or needle shaped, and decidedly spreading from the stem, though sometimes with a decurrent base. (=LL.=) =LL.= Leaves narrowed to a distinct though short stem. (=RR.=) =LL.= Leaves sessile; if narrowed, not so abruptly as to form a petiole. (=MM.=) =MM.= Leaves opposite or whorled on the stem. (=PP.=) =MM.= Leaves rather spirally arranged around the stem, not just opposite. (=NN.=) =NN.= Leaves linear to lanceolate, flattened, spreading quite squarely from the stem. (=OO.=) =NN.= Leaves not flattened but 4-sided, curved, gradually enlarging from the tips to the bases, which are decurrent, and on the young twigs completely cover the stem; cones rounded; the scales not lapping 105. _Cryptomeria._ =OO.= Leaves about linear in form, of nearly the same width throughout, and usually fastened to the cylindrical stem by a distinct disk-like base; cones erect; scales lapping. 96. _Abies._ =OO.= Leaves about 2 in. long and gradually widening from the acute tips to the broad (1/8 in.) bases, which are decurrent on the stem 99. _Cunninghamia._ =OO.= Leaves ½-1 in. long, sharp-pointed, very flat, two-ranked, somewhat lanceolate in form; base narrowed almost to a petiole 102. _Sequoia._ =PP.= Leaves not decurrent, usually in whorls of three around the stem, sometimes opposite, acute-pointed; fruit small (1/8 in.), rounded, dark-colored berries 106. _Juniperus._ =PP.= Leaves decurrent on the stem, less than ½ in. long. (=QQ.=) =QQ.= Fruit small, globular cones; the scales not lapping 104. _Chamæcyparis._ =QQ.= Fruit small, elongated cones of few, lapping scales 103. _Thuya._ =RR.= Leaves usually but little flattened, but jointed to a short, brown petiole which is attached to a somewhat grooved twig; cones pendent, of lapping scales 94. _Picea._ =RR.= Leaves decidedly flattened, not jointed, but narrowed to a petiole which is usually green or greenish in color. (=SS.=) =SS.= Leaves rounded or obtuse at the tip, distinctly two-ranked, usually less than 1 in. long; cones oval, 1 in. or less long, of lapping scales 95. _Tsuga._ =SS.= Leaves acute at the tip; fruit (found only on a portion of the plants, as the flowers are dioecious) drupe-like, with a single nut-like seed.
