对来自加拿大新斯科舍省米纳斯盆地的海葵N.vetensis Stephenson进行了4种筛选技术的组织学研究。这些结果表明，至少存在4种类型的腺细胞。除了一个例外，线虫包囊平均比手工测量的小(1957)。肠系膜的纵向牵引肌和弹性纤维夹在一条狭窄的中胚层之间，这与斯蒂芬森(1935)和克罗威尔(1946)的图解相矛盾。在所研究的276只海葵中，有6只海葵出现雌雄异株现象，仅在8-9月采集的海葵中发现雌雄异株的海葵。观察发育至平坦期。
The histology of the anemone N. vectensis Stephenson from Minas Basin, Nova Scotia [Canada] was investigated using 4 straining techniques. These revealed the presence of at least 4 types of gland cells. With one exception, nematocysts averaged smaller than those measured by Hand (1957). Longitudinal retractor muscles and elastic fibers in the mesenteries sandwiched a narrow band of mesoglea, contradicting diagrams in Stephenson (1935) and Crowell (1946). The dioecious occurrence of gonads was found in 6 of 276 anemones examined and only in anemones collected during Aug. and Sept. Development to planula stage was observed.
