The tree's female cones are about 10 mm in diameter, while cone scales are normally 6–8 mm. Often, but not always, they have conspicuous umbos 3–4 mm, which are high and conical. There are normally 100-125 seeds per cone, not at all glaucous. 3-4 cotyledons are usually present.
Cones form on slender fruiting branchlets that are solitary and separated from one another. [3] Both the male and female cones form on the same tree, with the male cones appearing on the end of branchlets at a size of 2–3 mm long, while the female cone forms on a branchlet that has a waxy, greyish-blue coloring during its development.

Callitris is a genus of coniferous trees in the Cupressaceae (cypress family). There are 16 recognized species in the genus, of which 13 are native to Australia and the other three (C. neocaledonica, C. sulcata and C. pancheri) native to New Caledonia. [1]
The reproductive age of the Santa Cruz cypress is on average 11 years of age. Seed viability falls to 10 percent by the time a tree is 30 years old. [8] Like some other coniferous trees, the seed-bearing cones of the Santa Cruz cypress depend on fire to heat open the cone and release the seeds. The fires burn the vegetation in the area ...
Hesperocyparis arizonica was given its first scientific name and described by Edward Lee Greene in 1882 as Cupressus arizonica, placing it in genus Cupressus. [3] [5] This description was soon after disputed by Maxwell T. Masters who, in 1896, published a journal article where he said it should be considered a subspecies of Cupressus benthamii with the variety name of arizonica. [3]
A gigantic cypress tree found in a canyon in Tibet stands as the tallest tree ever discovered in Asia and the second tallest in the world.. The tree, measuring over 335ft in height and nearly 9 ...
The tree bark is dark red or brown and has deep grooves. The seeds are found in cones about 2 cm in length, with eight scales and five seeds with tiny resinous vesicles. With the tree being a hybrid, its seeds are sterile. Over time, the cones shrink dry and turn gray or chocolate brown and then have a diameter of 1 cm. [12]
In general, lemon cypress trees won’t need to be fertilized at all, but if your plant looks like it needs a pick-me-up, fertilize it just once a year in early spring with compost or a diluted ...
