緬甸雲杉形態特徵
喬木,35米高; 樹皮淺灰色,有鱗; 樹冠開闊,寬圓錐狀; 分枝平展的或稍下斜,纖細; 小枝陡峭下降,最後的強烈下垂; 第1 和2年小枝橄欖去淺橙棕色,最初短柔毛,後脫落的的棕色。
小枝的上面邊上的向前指導的葉(但不是貼伏), 稍向前指導在下部邊, 藍色綠色的具輕微的蠟被, (1.5-)1.8-2.3(-2.5)厘米,扁平,與被適合長度中大多數人站在一起相似;
雄球花圓錐狀圓筒狀,約厘米 * 約3毫米球果無梗或非常短的pedunculacircaeduncle約0.5厘米),中間的棕色,橢圓形圓筒狀, ( 6-)7-9.5(-10) * 3-4 當打開時,厘米。
孢子葉球的種鱗在中部倒卵形,凸, 0.8-1.2 * 1-1.6 厘米,上部邊緣多少,rocircirca種子大約 1.6 * 0.5 厘米包括翅; 翅淡褐色,邊緣齧蝕狀。
Trees to 35 m tall; bark grayish, scaly; crown open, broadly conical; branches spreading or slightly descending, slender; branchlets steeply descending, ultimate ones strongly pendulous; 1st- and 2nd-year branchlets olive brown to pale orange-brown, initially pubescent, later glabrescent.
Leaves directed forward (but not appressed) on upper side of branchlets, slightly directed forward on lower side, blue-green with slight bloom, (1.5-)1.8-2.3(-2.5) cm, flattened, parallel sided for most of length, covered with bright snow-white epicuticular wax adaxially, stomatal lines 5 or 6 in each of 2 bands adaxially, apex abruptly acute, somewhat pungent.
Pollen cones conical-cylindric, 2-2.5 cm × ca. 3 mm. Seed cones sessile or very shortly pedunculate (peduncle ca. 0.5 cm), mid brown, ellipsoid-cylindric, (6-)7-9.5(-10) × 3-4 cm when open.
Seed scales at middle of cones obovate, convex, 0.8-1.2 × 1-1.6 cm, distal margin ± incurved, rounded. Seeds ca. 1.6 × 0.5 cm including wing; wing pale brown, margin erose.[2]
