Meanwhile, the critical Marangoni number for the incipience of hydrothermal wave (Ma_{c}=3.06\times 10^{5}) in the pool heated from inner wall is smaller than that (Ma_{c}=3.34\times 10^{5}) heated from outer wall.

After 30 days, the cultures were preserved in darkness, and 4 types of resting cysts were found after another 90 days:(1) spherical to ovoid cysts (25-39 μm long) covered by asparse or numerous calcareous attachments (1-4 μm long) and a calcareous surface;(2) spherical cysts (29-35 μm diameter) with a noncalcareous surface attachment, calcareous surface;(3)spherical to ovoid cysts (29-35 μm long) w ithout any surface attachment and a calcareous surface; and (4) spherical c ysts (24- 35 μm diameter) without any surface attachment and an organic surf ace.
培养30天后，培养液中有大量休眠孢囊，将藻液避光保存90天后，观察到培养基中有4种类型的休眠孢囊产生：(1)球形到椭球形(长25-39 μm)，钙质外壁，稀疏或密被钙质附属物(长1-4 μm)；(2)球形(直径为29-35 μm)，钙质外壁，附属物非钙质(长0.5-1.5 μm)；(3)球形到椭球形(长29-35 μm)，钙质，表面光滑，无附属物；(4)球形(直径24-35 μm )，有机外壁，无附属物。

Pollen morphology and exine ultrastructure Pollen exine ultrastructure of five species in Stachyurus and one species of its sister group, Crossosoma californicum, were investigated under transmission electron microcopy for the first time. The pollen morphology of Crossosoma californicum was studied under Scanning Electron Microcopy.
花粉形态学和外壁超微结构在透射电镜下研究了旌节花属5个代表种和1个外类群的花粉外壁超微结构，并在扫描电镜下研究了外类群Crossosomataceae 1个代表种的花粉形态学特征，结合前人的研究，探讨了上述性状的分类学意义。

The ornamentation of exosporium varies from species.
苔藓孢子的外壁纹饰不同，一般认为孢子外壁光滑是进化性状，外壁上各种突起排列密集的则较为原始。
