Pinguicula alpina is hemicryptophytic, in that the plant survives the cold winter conditions by reducing to a bud resting on the soil surface. This bud, called a hibernaculum, is composed of small, densely packed leaves, which unfurl with the coming of spring.
A hibernaculum (plural form: hibernacula) (Latin, "tent for winter quarters") is a place in which an animal seeks refuge, such as a bear using a cave to overwinter.The word can be used to describe a variety of shelters used by many kinds of animals, including insects, toads, lizards, snakes, bats, rodents, and primates of various species.
Hibernaculum (plural hibernacula) is the term often applied to a winter bud of certain aquatic plants, such as the bladderworts (Utricularia). The buds are heavier than water, and, being developed at the approach of cold weather, they become detached, sink to the bottom of the pond, and thus survive the winter.
Sheep and goats also browse the foliage, as do game animals including elk. [17] [18] Grouse and quail especially eat the buds in winter. Mammals such as beavers and rabbits eat the bark, foliage, and buds. [17] Beavers also store aspen logs for winter food. Other animals nest in aspen groves. [7]
The winter twigs are distinctive among North American trees, being long and slender (15–20 millimetres or 5 ⁄ 8 – 3 ⁄ 4 inch by 2–3 mm or 3 ⁄ 32 – 1 ⁄ 8 in) with two rows of overlapping scales on the buds. Beech buds are distinctly thin and long, resembling cigars; this characteristic makes beech trees relatively easy to identify.
In the summer it is speckled in gray, brown and white whereas in winter it is wholly white. At all times of year the wings, belly and tail are white. The white-tailed ptarmigan has a diet of buds, leaves, flowers and seeds. The nest is a simple depression in the ground in which up to eight eggs are laid. After hatching, the chicks soon leave ...

Plant buds classification Terminal, vegetative bud of Ficus carica. Buds are often useful in the identification of plants, especially for woody plants in winter when leaves have fallen. [4] Buds may be classified and described according to different criteria: location, status, morphology, and function. [citation needed]
