关于此标本
尺寸: 3.8 × 3.6 × 3.3 cm (1.50 × 1.42 × 1.30 in) · 38 mm (1.50 in).
黄褐色的叶片自锈色核心朝各个方向迸发,其中一些半透明到足以让光沿着叶身穿行,而几乎每一片都结着细小的白色晶体,像落在蕨叶上的霜。 整体读来,是一颗直径约 3.8 cm 的粗糙尖刺球,中心致密而深,末端疏朗而浅。
石膏的化学式是 CaSO4·2H2O,是一种莫氏硬度 2 的矿物——指甲即可划出痕迹——而像这样的玫瑰状集合体,形成于叶片在开放空腔中围绕一个共同点成核,并在空间允许的范围内向外放射之时。 这种矿物微溶于水,因此湿气是唯一必须远远避开的东西;轻轻使用一支干刷,就是全部的清洁程序,而封闭的标本柜比开放层架更适合它。
这朵玫瑰状集合体尺寸为 3.8 × 3.6 × 3.3 cm,重 30 g,以黏土固定于图中的透明压克力方块上。 那些照片正是为这一朵而拍,寄出时也附上图中的方块。
