Genus 1. Lisoceprus, Endlicher. 
Shrubs or lofty trees. Branchlets compressed when young, tetragonous 
when old. Leaves small and scale-like, opposite: on young plants the lateral 
leaves are larger than the upper and lower; on old trees all the leaves are equal 
or nearly so, quadrifariously imbricate. Flowers monoecious or dicecious : 
catkins solitary, terminal. Male: Cylindrical; stamens, six to ten, connective 
peltate ; anther-cells pendulous. Female of four to six erect decussate scales, 
the two innermost with an erect fleshy scale or disc at the base of each, carrying 
two naked ovules. All the scales become woody in fruit, and carry a short 
curved spine or horn at the back ; seeds, two or four, unequally winged. 
Genus 2. Puyittociapus, L. C. Rich. 
Shrubs or trees, moncecious or dicecious, with whorled branches, leaves 
of two forms, linear, developed chiefly on young plants, or minute and scale- 
like. In old plants leaves are represented by flattened, flabellate, coriaceous 
branchlets termed cladodia, which are often lobed or toothed, and carry the 
female flowers on their margins. Male catkins terminal, usually fascicled, 
sessile or pedicellate: stamens imbricated ; anther-cells, two. Female catkins 
very small, one- or many-flowered, each flower consisting of a single erect naked 
ovule, seated on a fleshy scale, ultimately coriaceous. Fruit amorphous or 
elobular, coriaceous, often coloured; the seeds longer than the scales. 
Genus 3. Dacrypium, Solander. 
Shrubs or lofty trees, stems, rarely, short and prostrate, dicecious or, rarely, 
moncecious. Leaves dimorphic, linear, and distichous, or subulate or scale-like, 
quadrifariously imbricating. Male catkins terminal, short, sessile, usually con- 
sisting of few small imbricating stamens, rarely long and acuminate: anthers 
sessile, two-celled. Female of one or more scales, one or two of which bear a 
naked inverted ovule. Fruit, a seed invested at the base by a membranous cup, 
and seated on a coriaceous or fleshy receptacle. 
Genus 4. Popocarpus, L’Hertitier. 
Trees or shrubs, dicecious or, rarely, moncecious. Leaves sometimes 
dimorphic, distichous or scattered, or subulate, spreading or imbricated. 
Flowers axillary or terminal. Male catkins solitary or racemed, rarely spiked : 
stamens numerous, imbricate; anther-cells, two. Female of two, rarely four, 
elongate scales, forming a two- to four-toothed receptacle, usually pedunculate ; 
one or more of the scales carry a naked inverted ovule adnate to its face, but 
usually only one ripens into fruit. Fruit, a drupe or seed seated on a fleshy 
or dry receptacle. 
Genus 5. AcatuHis, Salisbury. 
Lofty moncecious trees with broad flat leaves, the branches often whorled. 
Flowers with a very short stout peduncle, and usually three or four bracts, 
forming a kind of cup at the base of the catkin. Male: tin. to 1gin. long; 
stamens numerous, closely imbricating ; connective peltate ; anther-cells, five to 
twenty, pendulous. Female catkin ovoid or glandular: scales numerous, each 
with a single inverted ovule. Fruit, a woody cone, which falls to pieces as soon 
as the seeds are ripe.
