纤毛

Inflorescence terminal, composed of several to many racemes inserted digitately or along a short axis; racemes elongate with many spikelet pairs, hairy, fragile, sessile and pedicelled spikelets of a pair similar, pedicelled often slightly narrower, both fertile; rachis internodes linear, ciliate along angles; pedicels resembling internodes, usually slightly shorter and more slender.

花序顶生，由数枚到多数总状花序组成着生或沿着短轴；总状花序拉长具很多小穗对，有毛，脆，无梗和pedicelled相似的对，pedicelled通常稍狭窄，都能育；轴节间的线，纤毛的沿着棱；花梗象节间，通常有点更短和更纤巧。

Leaf blades usually linear or lanceolate; ligule membranous, a line of hairs, or a short membrane with ciliate fringe (rarely absent in some Echinochloa ).

Lastly, based on analysis on phylogentic relationships among 39 ciliates combined with their main morphologic characters, some conclusion were drawn: 1 the monophyly of the peritrichs was strongly supported, and its subclass rank in the class Oligohymenophorea is reasonable; 2 the genus Epistylis might not be monophyletic, and the peristomial area, especially the peristomial lip, might be an important phylogenetic character within the genus Epistylis; 3 the taxonomic rank of the genus Carchesium and the genus Campanella were suggested to be adjusted; 4 Opisthonecta probably diverged from peritrichs with stalks; 5 the phylogenetic tree of peritrichs was reconstructed based on the molecular information inferred from SSrRNA gene sequences and the morphology.

测定了6科8属13种缘毛类纤毛虫的SSrDNA序列，将构建的最大简约树和邻接树与形态学相结合，分析得出：1）缘毛类纤毛虫是单系的，其分类地位是隶属于纤毛门寡膜纲缘毛亚纲：2）指出累枝虫属可能不是单系的，口围区是累枝虫属中重要的系统发育特征；3）建议调整独缩虫和聚钟虫属的分类地位；4）得出后游虫可能是由有柄缘毛类进化而来的类群；5）基于缘毛类反口区结构和SSrRNA基因序列提供的信息重建了缘毛类纤毛虫的系统发育树。
