New intranuclear crystals were described in cells of Chara vulgaris. These were needle-like structures extending for about 8 μ in length and 350mμ×110mμ in transverse dimensions. Each crystal was composed of hexagonally-packed, tubular structures about 200-240 Å in diameter, apparently running parallel to each other along the longitudinal axis. Such crystals appeared to pass through one of the several nucleoli in each nucleus. It is suggested that the crystals are proteins having a storage function, which are synthesised in the nucleolus.
在普通小球藻的细胞中描述了新的核内晶体。这些晶体是针状结构，长度约为 8μm，横向尺寸为 350μm×110μm。每个晶体由直径约为 200-240Å 的六边形排列的管状结构组成，显然沿着纵轴彼此平行排列。这些晶体似乎穿过每个核中的几个核仁之一。因此，这些晶体可能是具有存储功能的蛋白质，它们在核仁中合成。
