Branches may be up to 5 mm in diameter and up to 1 metre long. Its cones are red and fleshy, and borne terminally on the horizontal branches. [2] The seed is dark brown on red fleshy scales. [3] It is believed to be the smallest conifer in the world and is rarely bigger than a small low-growing shrub. [4]

In general, this classification emphasized cone, cone scale, seed, and leaf fascicle and sheath morphology, and species in each subsection were usually recognizable by their general appearance. Pines with one fibrovascular bundle per leaf, (the former subgenera Strobus and Ducampopinus ) were known as haploxylon pines , while pines with two ...
The pine cones of the tree resemble the cones of the Siberian pine (P. sibirica). The cones are larger and thicker and not as much elongated as Japanese stone pine (P. pumila) cones. On average the cones are 4 cm long and 3 cm wide. Each cone contains 40 nut-like seeds. Seeds are on average 8 mm long. Only about 15% (at most) of the seeds in ...
Pinus pumila, commonly known as the Siberian dwarf pine, dwarf Siberian pine, [1] [3] dwarf stone pine, [1] Japanese stone pine, [3] or creeping pine, [4] is a tree in the family Pinaceae native to northeastern Asia and the Japanese isles. It shares the common name creeping pine with several other plants.
The cones open to 10–15 cm (4–6 in) broad when mature. The seeds are 2–3 cm ( 3 ⁄ 4 – 1 + 1 ⁄ 4 in) long, with a thick shell, with a vestigial 1–2 mm (0.04–0.08 in) wing; the seedlings have 18–24 cotyledons , the highest number reported for any plant.
Table Mountain pine typically has long, thick limbs on much of the trunk even in closed canopy stands. [7] Male cones are 1.5 centimetres (0.59 in) long. Female cones are sessile and range from 4.2 to 10 centimetres (1.7 to 3.9 in) long. [7] Cone scales are tough and armed with broad, upwardly curving spines. [6]
