植物简介 Descriptions
克罗特龟背竹是以托马斯·B·克罗特博士（密苏里植物园）命名，是哥斯达黎加的特有种，仅分布在该国南部太平洋一侧的戈尔菲托地区以及戈尔菲托县的科尔科瓦多国家公园，海拔约 300 - 600 米处，生长在原始森林和次生森林以及开阔地带。它在该属中是独特的，主要是陆生植物，能够在没有附生生长习性的情况下长到成年大小，而其他龟背竹在找到适合攀爬和成熟的基质之前会一直处于匍匐的幼年期状态。它通常在开花前爬到一米高。成年植株有光滑的、带有蓝色调的绿色叶柄，长达 45 厘米，叶片为长椭圆形，深羽状分裂，长达 45 厘米，宽 33 厘米。成年标本不形成穿孔。它的佛焰苞长达 14 厘米，开花时外部为黄白色，有一个 8 厘米长的白色肉穗花序。至今未观察到成熟的果实和种子，也没有采集到可育的标本。克罗特龟背竹在二月有未成熟的果序记录，在十月和十一月观察到花朵。
克罗特龟背竹（M. croatii）很容易与羽裂暹罗龟背竹（Monstera pinnatipartita）混淆，但可以通过以下几种方式加以区分。首先，羽裂暹罗龟背竹永远不会在陆地上形成其成年营养体形式；其次，它的叶柄有白色斑点，而克罗特龟背竹的叶柄呈蓝灰色且光滑。
Monstera croatii is a flowering plant in the family Araceae. It is endemic to Costa Rica at altitudes of 300-600 meters (984-1968 ft). It is unique within the genus for being a primarily terrestrial grower, able to reach adult size without an epiphytic growth habit, whereas other monstera will remain in a creeping juvenile state until finding a suitable media for climbing and maturing. It will typically climb up to one meter (3 ft) before flowering. Adult plants have smooth, blue-tinged green petioles up to 45 centimeters (18 in) long, with oblong, deeply pinnatifid leaf blades up to 45 centimeters (18 in) long and 33 centimeters (13) wide. Adult specimens do not form fenestrations. Its spathe is up to 14 centimeters (6 in) long, externally white-yellow at anthesis, with a white spadix 8 centimeters (3 in) long. Mature fruits and seeds have not been observed, and no fertile specimens have been collected to date. M. croatii has immature infructescences recorded in February, with flowers observed in October and November.
M. croatii is easily confused with Monstera pinnatipartita, but can be differentiated in several ways. First, M. pinnatipartita will never develop its adult vegetative form terrestrially; second, it has white-speckled petioles, unlike the glaucous and smooth petioles observed in M. croatii.
