Frullaniaceae are the most diverse family of leafy liverworts preserved in amber and are known from several deposits dating from the Miocene to the Early Cretaceous. In the fossil record, Frullania is represented by 15 species as well as the extinct genera Pseudofrullania, Protofrullania and Kaolakia. Here, we describe another species of Frullania from Bitterfeld amber (Germany) as Frullania grabenhorstii sp. nov. A combination of characters associated with the leaf lobe, leaf lobule, underleaf, branching patterns, and perianth distinguishes it from all other known extant and extinct taxa. Many characters of the new fossil are shared with F. subg. Frullania sect. Australes, especially the morphologically similar extant species F. incumbens and F. subincumbens-both of Australasia. Another similar species, Fullania densiloba, occurs in Japan. These distribution patterns reinforce previously described affinities of the Baltic and Bitterfeld bryophyte floras to the extant flora of Asia and Australasia. This pattern has been found in several taxa, e.g., Notoscyphus, Nipponolejeunea, and Metacalypogeia. The new fossil is compared with other species from Bitterfeld, Baltic, and Rovno amber, which show significant morphological differences. In addition to the description, we provide an overview of the family Frullaniaceae in different amber deposits.

Geocalyx heinrichsii T.Katag. is described as a new leafy liverwort species from Eocene Baltic amber. It is characterized by (1) small sized shoots less than 1 mm wide including leaves, (2) bifid underleaves, not connate with leaf bases, (3) presence of gemmiferous ascending microphyllous shoot, and (4) 1–2-celled spherical to ellipsoidal gemmae. This is the first fossil record for the genus Geocalyx and for the family Geocalycaceae (Jungermanniales, Marchantiophyta) from Baltic amber, and constitutes an important addition to our knowledge of the Eocene Baltic liverwort flora.

Frullania is a large and taxonomically complex genus with over 300 accepted species. A new liverwort species, Frullania thouvenotiana sp. nov. from New Caledonia, is described and illustrated. The new species, and its placement in Frullania subg. Microfrullania, is based on morphology with support from previously published sequence data. Diagnostic characters associated with the leaf, especially the leaf margin, distinguishes it from all other species of Frullania, including similar species with a distribution comprising Fiji and New Zealand. A brief comparison is made with morphologically allied species, and an artificial key is provided. Frullania neocaledonica is also proposed to be a synonym of F. chevalieri.

The recent rediscovery of the rheophytic endemic Ceratolejeunea temnantha ~130 years after its original description, on the upper Rio Negro in the Brazilian Amazon, has enabled the assessment of its enigmatic phylogenetic position, estimates of its divergence time, and updates on its distribution and potential habitat threats. Phylogenetic analyses strongly supported its placement in the genus Ceratolejeunea in a geographically disparate clade including a Madagascar endemic C. saroltae and two Neotropical taxa, C. confusa and C. caducifolia. Divergence time estimates date the clade’s stem age to the late Miocene (8.92 [HPD: 12.39–6.04] Ma) offering further evidence that the evolution of rheophytes in northern South America is correlated with the expansion of cryptogams into novel ecological niches promoted by dramatic landscape changes during the Miocene. Major geomorphological and hydrological transformations contributing to such diversification are most likely the changing dynamics of the inundated mega lake system to the establishment of the Amazon River due to the Andean orogeny and the subsequent cessation of marine influences in the north-western portion of the Basin. Until recently, this rheophyte of seasonally inundated black-water forests was only known from its type collection from the Rio Negro near São Gabriel da Cachoeira (Brazil) as described by Richard Spruce in 1884. These new collections extend the distribution of this rare narrow endemic to the middle Rio Uaupés, a tributary of the upper Rio Negro near the Columbian border.
最近，在巴西亚马逊河上游里约热内卢Negro地区重新发现了一种距今约130年的流变性特有Ceratolejeunea temnanea，从而能够评估其神秘的系统发育位置，估计其分化时间，并更新其分布和潜在的栖息地威胁。系统发育分析有力地支持了其在Ceratolejeunea属中的位置，该分支包括马达加斯加特有的C. saroltae和两个新热带分类群C. confusa和C. caducifolia。据估计，该支系的分化时间可追溯到中新世晚期(8.92 [HPD: 12.39-6.04] Ma)，这进一步证明了南美北部流变植物的进化与中新世剧烈的景观变化所促进的隐生植物向新生态位的扩张有关。促成这种多样化的主要地貌和水文变化很可能是由于安第斯造山运动和随后盆地西北部海洋影响的停止而导致的淹没大湖系统的动态变化，以及亚马孙河的形成。直到最近，这种季节性淹没的黑水森林的流生植物仅从它的类型收集中被人们所知，这些类型收集来自 o Gabriel da Cachoeira(巴西)附近的里约热内卢Negro，如Richard Spruce在1884年所描述的那样。这些新收集的标本将这种罕见的狭窄地方性植物的分布范围扩展到了哥伦比亚边界附近的上里约热内卢Negro的一条支流——中部里约热内卢uaupsamas。

Frullania heinrichsii (subg. Chonanthelia sect. Cladocarpicae) is newly described from Peru. The new species is characterized by its robust size, undulate leaf margins, undivided underleaves with strongly auriculate bases, autoicous sexuality and 4-keeled perianths. The species has morphological affinities with F. holostipula, F. obscura and F. rio-janeirensis, blurring the subsectional classification boundaries between these species. As a result, subsect. Holostipulae and subsect. Quadriplicatae are proposed as synonyms of sect. Cladocarpicae. Frullania holostipula, hitherto only known from Venezuela, is newly reported from Bolivia. An updated key is provided to the thirteen species recognized in sect. Cladocarpicae.

A taxonomic study of the propaguliferous species of the genus Pohlia with axillary and rhizoidal propagules in China is presented. Structure in the variation in size and form of the propagules provides a basis for distinguishing species although developmental variations often exist in the propagules. Ten species are recognized in the study area, including two new records: Pohlia andalusica and P. andrewsii. P. andalusica has obconic propagules with erect-spreading laminate leaf primordia clustered in the leaf axils. The oblong, translucent, reddish-orange, axillary propagule with inconspicuous peg-like protuberances of leaf primordia that are incurved at the apex is a distinctive trait of P. andrewsii. P. hisae is an endemic species to China. The species is distinct because of its axillary propagules, which are obconic to ovate, with long, flexuose peg-like leaf primordia. In addition, the glossy shine of the plants when dry is a good diagnostic feature of Pohlia proligera, P. andrewsii and P. andalusica. Taxonomically important characters of all Chinese propaguliferous Pohlia are provided, as are photomicrographs of propagules and an artificial key to these species. The global distribution and specify provinces in China for each species have been summarized.
对中国具有腋生和根生繁殖体的茯苓属植物进行了分类研究。尽管繁殖体中经常存在发育变异，但其大小和形态变化中的结构为区分物种提供了依据。研究区已发现10种，其中新记录2种:波利亚(polhlia andalusica)和安德鲁种(P. andrewsii)。安达卢卡的繁殖体为倒锥状，直立铺展的层叠叶原基簇生在叶腋上。长圆形，半透明，红橙色，腋生的繁殖体，叶原的不明显的钉状突起，在先端弯曲，是凤梨的一个显著特征。海棠属中国特有种。该种是独特的，因为它的腋生繁殖体，这是倒圆锥到卵形，具有长，弯曲的钉状叶原基。此外，植物在干燥时的光泽是proligera, P. andrewsii和P. andalusica的一个很好的诊断特征。本文提供了中国所有繁殖型波利亚的分类学上的重要特征，并提供了繁殖体的显微照片和这些物种的人工钥匙。总结了各种属的全球分布和在中国的特定省份。

Insect induced galls are not known from bryophytes. Here we report the first occurrence of such galls from thalli of a neotropical liverwort, Monoclea gottschei subsp. elongata (Marchantiophyta: Monocleaceae) from Peru. This is also the first report of animal-induced galls formed in modern thalloid liverworts. The gall-inducer is a species of the family Agromyzidae (Diptera). The galls are swellings, but are otherwise indistinguishable from intact thalli as their surface is neither ornamented nor sclerotized. The histology of the galls, however, suggested that abnormal cell growth and some differentiation occurred in the parenchymatous cells of the thalli during gall formation.
