Evergreen trees or shrubs with opposite or verticillate, subulate or scale- 

 like, sessile leaves, commonly of 2 kinds, and dioecious or sometimes monoecious, 

 small globose axillary or terminal aments. Leaf-buds naked. Staminate 

 aments oblong or ovoid; anthers 2-6-celled, each sac 2-valved. Ovule-bearing 

 aments of a few opposite somewhat fleshy scales, or these rarely verticillate in 

 3's, each bearing a single erect ovule or rarely 2. Cones globose, berry-like by 

 the coalescence of the fleshy scales, containing 1-6 wingless bony seeds. 

 [Name Celtic] About 40 species, natives of the northern hemisphere. Type

Palm-like or fern-like, dioecious, woody plants with erect trunks, some-

 aceous, the segments entire or toothed, parallel-veined, the petioles unarmed in 

 the following species, prickly in some others, the inflorescence strobilar, pe- 

 duncled, densely many-flowered, the cones from oblong-cylindric to subglobose, 

 the female thicker than the male. Scales of the cones peltate, nearly flat, more 

 or less hexagonal, closely set together, vertically superimposed. Scales of the 

 male cone at length deciduous, bearing several sessile pollen-sacs, those of the
