Sandarach is the produce of the thuya articulata of Barbary.
Some of the green or glaucous varieties of both Cupressus and thuya will come fairly true from seed, from 40 per cent.
Arborvits (thuya) have very small overlapping leaves that form flat rods or fan-like sprays.
This is the Oregon cedar (thuya gigantea), which attains great size and is widely diffused on the trans-Rocky region.
All the species and beautiful varieties of Cupressus, thuya, and Juniperus are very valuable in a young state.
Thyoides is from thuya meaning arborvit and eidos, the Greek for "resemblance."
