Topic: Cupressaceae


  
  Cupressaceae description
Phylogenetic tree for the Cupressaceae derived from a combined database for the chloroplast gene locus matK and the plastid gene locus rbcL.
All genera treated here have seed cones in which the bract-scale complexes are fused for most of their common length, the 1-20 ovules are erect (but may invert with maturity), and the paired seed wings, if present, are derived from the seed coat (Eckenwalder 1976, Watson and Eckenwalder 1993).
The heartwood of many species of Cupressaceae is resistant to termite damage and fungal decay, and therefore it is widely used in contact with soil [e.g., for fenceposts].

 Non-Flowering Plant Families, UH Botany
The Cupressaceae are monoecious or dioecious trees or shrubs comprising about 18 genera and 140 species.
The leaves are usually scalelike, and are opposite and decussate, or whorled.
At a later stage of development (right) the scales have dried and reflexed and the winged seeds have been shed.

The Cupressaceae are also the most important conifer family in modern horticulture Several species of Chamaecyparis, Cupressus and Juniperus are of major importance in horticultural trade, accounting for about 99.9% of all conifers sold for garden planting in Britain; many thousands of cultivars have been named.

 Cupressaceae in Flora of North America @ efloras.org
The unity of the family is best shown in the structure of the mature seed cones: the bract-scale complexes are intimately fused for most of their common length, the 1--20 ovules are erect at first but may invert with maturity, and the paired seed wings, if present, are derived from the seed coat.

 pollen grain morphology juniper   (Site not responding. Last check: 2007-10-16)
Members of the Cupressaceae possess scale-like leaves appressed to the terminal twigs.
Although the genus name Juniperus is frequently applied to this pollen type in North America, many other plant genera produce pollen of this type, so the term "Cupressaceae" is used in regions where other members of the plant family occurr.
The splitting of the pollen grains apparently speeds the grains' deterioration, and juniper pollen is not well preserved.
