The adult females resemble the bud of their coniferous hosts, [4] hence the name bud scale. Physokermes are difficult to identify to species, as only pre-reproductive females can be used. [ 4 ] Once females begin to oviposit , their bodies become distorted and it is not possible to detect the morphological features necessary to identify them to ...
Picea engelmannii, with the common names Engelmann spruce, [3] white spruce, [3] mountain spruce, [3] and silver spruce, [3] is a species of spruce native to western North America. Highly prized for producing distinctive tone wood for acoustic guitars and other instruments, it is mostly a high-elevation mountain tree but also appears in watered ...
The buds are a very distinctive narrow conic shape, 4–8 mm (3 ⁄ 16 – 5 ⁄ 16 in) long, with red-brown bud scales. The leaves are spirally arranged but slightly twisted at the base to lie in flattish either side of the shoot, needle-like, 2–3.5 cm ( 3 ⁄ 4 – 1 + 3 ⁄ 8 in) long, green above with no stomata , and with two whitish ...

Picea glauca is native from central Alaska all through the east, across western and southern/central Canada to the Avalon Peninsula in Newfoundland, Quebec, Ontario and south to Montana, North Dakota, Minnesota, Wisconsin ...
For example, bud scales occur on numerous kinds of leaf or branch buds, as well as on flower buds. [citation needed] Protective masses of dead leaves encircle the stems of some species of palm trees or aloes, but those are not usually regarded as cataphylls because their primary function while alive is photosynthesis.

The buds are a distinctive narrow conic shape, 3–6 mm (1 ⁄ 8 – 1 ⁄ 4 in) long, with red-brown bud scales. The leaves are spirally arranged but slightly twisted at the base to be upswept above the shoot, needle-like, 2–3 cm ( 3 ⁄ 4 – 1 + 1 ⁄ 4 in) long, gray-green to blue-green above with a single broad stomatal patch, and with ...
Foliage of a dwarf Alberta spruce (Picea glauca var. albertiana 'Conica'), with a branch showing reversion [1] to the normal Alberta white spruce growth habit of larger leaves and longer internodes. In botany , a sport or bud sport , traditionally called lusus , [ 2 ] is a part of a plant that shows morphological differences from the rest of ...
The buds of many woody plants, especially in temperate or cold climates, are protected by a covering of modified leaves called scales which tightly enclose the more delicate parts of the bud. Many bud scales are covered by a gummy substance which serves as added protection. When the bud develops, the scales may enlarge somewhat but usually just ...
