OrpEeR ‘111 PINACE Lindl. Nat. Syst. ed. 2, 313. 
Resinous trees or shrubs, mostly with evergreen narrow or 
scale like entire leaves and monoecious or rarely dioecious 
flowers. Staminate flowers reduced to the stamens only which 
are indefinite in number and often numerous, the filaments 
upon a central axis with the 2 or more anthers either adnate to 
the back of the connective or suspended from the under 
side of its scale-like or peltate summit, the cells dehiscing 
variously. Pistillate aments consisting of few to many scales, 
becoming a dry cone in fruit or fleshy and berry-like. Ovules 
naked, two or more at or on the base of each scale, adnate or 
free, erect or.inverted. Seeds naked or winged, with chartace- 
ous or crustaceous or sometimes bony testa. Embryo straight, 
anh in fleshy oily albumen. Cotyledons two to several in a 
. whorl. 
TRIBE I | CupressInE& Scales of the fertile aments few, decus- 
sately opposite, apparently single, becoming a small cone or 
connate into a drupe-like globulus. 
* Leaves opposite or in three’s, never 2-ranked: flowers dicecious : 
fruit drupe-like, with bony ovate seeds. 
1 Juniperus Ovules in pairs or solitary at the base of the fleshy scales: 
seeds 1-5 or more: fruit globose, ripening the second season. 
* * Leaves opposite: flowers moneecious: fruit a dry cone. 
+ Cone subglobose, of spreading, peltate or cuneate scales: seeds 
one or more to each scale, angled or narrowly winged. 
2 Chamecyparis Leaves and branches more or less 2-ranked: seeds 
one or two to each scale. a, 
+ + Leaves 2-ranked: cone oblong, of imbricated or valvate ob- 
long scales: seeds 2 or more to each scale, maturing the first year. 
8 Thuja Scales 8-12, rather thin, imbricated: seeds equally 2-winged. 
4 Libocedrus Scales thick-coriaceous, valvate, only the middle pair 
fertile: seeds unequally 2-winged. 
‘TRIBE 11, TAXODINE Scales of the fertile aments more num- 
erous and spirally arranged, in fruit forming a woody cone. 
5 Sequoia Large trees with short-linear to ovate-lanceolate acute cari- 
nate leaves and ovate cones with cuneate spreading scales. 
TRIBE 11, ABIETINEZ Scales of the fertile aments numerous, 
spirally imbricated, carpellary, each in the axil of a thin distinct 
persistent bract, in fruit becoming coriaceous or ligneous and 
forming a strobile or cone.
