植物简介 Descriptions
强攀爬植物，大部分人工种植难以授粉育种，可能因为该品种开花常处于距地面15米左右距离，最长攀爬至30米，广泛分布于从墨西哥到中美洲。它在 Petén 中部地区数量丰富，并向北延伸至 San Luis Potosí,，使其成为龟背竹属中最北端的物种。
尖叶龟背竹在地面发芽，并作为一种低矮的匍匐草本植物水平生长。幼株要小得多，呈心形，有厚实、圆形、有蜡质的叶子，叶子成两列生长并相互重叠，茎的横截面为椭圆形，节间长 1 - 5 厘米，叶子不对称。
当它遇到树干时，会使用向地性的锚定根垂直生长。成年植株看起来与龟背竹（Monstera deliciosa）相似，当植株长到 15 英尺时会长出这些叶子，这是二型现象的一个例子。叶子光滑或具乳突，茎粗 2–3.5 厘米，节间长 6–11 厘米。向上生长后，半附生植物茎的基部会死亡和腐烂，从而失去与土壤的连接。
Monstera acuminata germinates in the ground and grows horizontally as a low prostrate herb.The juvenile plant is much smaller and heart-shaped with thick, roundish, waxy leaves which grow in two ranks and overlap each other with the stem elliptic in cross section and internodes 1–5 cm long and asymmetric leaves.
When it encounters a tree trunk, it uses its ageotropic anchoring roots to grow vertically. The adult plant appears similar to that of Monstera deliciosa and these leaves are developed when the plant reaches 15 feet and is an example of dimorphism. The leaves are smooth or papillose stem 2–3.5 cm thick with internodes 6–11 cm long. After it grows upwards, the base of the stem of the hemiepiphyte dies and rots, thereby losing its connection to the soil.
