ovulate flowers often solitary. Seeds borne in cones of dry or fleshy scales,

 woody and spreading or reflexed, each with a dorsal, usually spine-armed 

 appendage. Seeds samara-like. PINE. 



Bracts of the ovulate aments not awn-tipped : stnmlnnte aments over 3 cm. long : 

 resin-ducts of the leaf against the bundles. L. P. 



Bracts of the ovulate aments awn-tipped : stamlnate amenta less 



than 1.5 cm. long : resin-ducts of the leaf away from the bundles. 2. P. clauta. 



1. P. caribaea Morelet. Tree with coarse, flaky bark, branched near the top: 

 leaves in 2's or 3's, 18-30 cm. long, or sometimes shorter, bright -green: cones

2. P. clans* (Engelm.) Vasey. Tree with relatively or quite smooth bark,

 Mostly evergreen, often resiniferous shrubs or trees, with fibrous, 

 shreddy bark. Ix-avcs mainly appressed scales, sometimes subulate or 

 linear and spreading. Ovulate aments with bractless scales. Mature 

 ovulate cone of dry, often peltate scales, or baccate or drupaceous. Seeds 

 wingless or winged.

Cooes berry-like; scales fleshy : seeds not sharp-angled. 2. SAIUNA. 



1. TAZODITJM L. C. Rich. Roots producing erect conic " knees. " Leaves 

 often 2 ranked, deciduous: blades narrow. Staminatc aments in panicles or 

 racemes. Ovulate aments with peltate scales. Cones spreading, the woody 

 scales sulked. CYPRESS. 



1. T. dlstichum (L.) L. C. Rich. Tree with a roni. trunk-Lai*, the bark nar- 

 rowly ridged: leaves 1-1.5 cm. long, often curved: staminate amonts in droop- 

 ing clusters: cones globular, about 2.5 cm. in diameter. Hammocks and Ever- 

 glades. BALD-CYPRESS. 



2. 8ABINA Halicr. Roots not producing "knees." Leaves scale-like and
