TL;DR: A revision is made of the genera Hypnodendron and Braithwaitea, and the circumscription of the family has been maintained unchanged for the time being in the absence of information regarding assumedly related families.
Abstract: A revision is made of the genera Hypnodendron and Braithwaitea. Mniodendron and Sciadocladus are reduced to Hypnodendron, Limbella is excluded from the Hypnodendraceae, and Dendro-Hypnum is considered to be not validly published. Hypnodendron rigidum Mitt. is transferred to Pterobryella. The species of Hypnodendron are grouped into nine sections. Five of these are monotypic, viz. Leiocarpos Dix. and four new ones: Lindbergiodendron (including H. arcuatum), Tristichophyllum (H. diversifolium), Mniodendropsis (H. milnei), and Pseudomniodendron (H. fusco-mucronatum). The circumscription of the family also needs revision, but has been maintained unchanged for the time being in the absence of information regarding assumedly related families.
A number of morphological and other characters are discussed. Hypnodendron is thought to be of pleurocarpous descent; Meusel’s derivation of the growth-form of Hypnodendron from that of the acrocarpous genera Mnium and Philonotis is rejected. Rejuvenation takes place by means of basal innovations, and in a number of erect species also by distal ones. The umbellate and palmate fronds are assumed to have been derived from a pinnate type. The Hypnodendraceae are distributed in the Indo-Pacific and Australasian regions and in southern South America. Hypnodendron is centred in Melanesia and New Zealand. 26 species are recognized, 9 of which are divided into subspecies or varieties; 5 taxa are reinstated (H. colensoi, H. comatum, H. comosum var. sieberi, H. spininervium ssp. spininervium and ssp. archeri) and 1 is described as new (H. vitiense ssp. australe). Identification keys are provided, and for each taxon are given: synonymy together with pertinent literature and typification, misinterpretations and misidentifications, description, geographical distribution, ecology, and notes on various subjects. Each species is illustrated, and a list is given of specimens examined, mostly accompanied by a distribution map.

TL;DR: The genusFallopiaAdans.
Abstract: The generic nameFallopia
Adans. 1763 is analysed from the point of view of its taxonomic identily and typified byPolygonum scandens L. 1753. By this typification it is taxonomically identical withBilderdykia
Dum. 1827 and must replace that name. The genusFallopia
Adans. is defined by comparison with related genera; it includes 9 species in two sections, and 1 hybrid; new nomenclatural combinations are proposed for these taxa.

TL;DR: Ways of typifying the two species so as to preserve current usage and still fulfil the requirement of the International Code of Botanical Nomenclature are given.
Abstract: The original descriptions of these two species are discussed and the material mentioned in Smith's description is examined. Discrepancies between Smith's description of Coscinodiscus concinnus and the present interpretation of this species are pointed out. Ways of typifying the two species so as to preserve current usage and still fulfil the requirement of the International Code of Botanical Nomenclature are given. Lectotypes for the two species are designated. Diagnostic characters distinguishing the two species in the living state as well as the cleaned valves are given.

TL;DR: The living fern-allies belongs essentially to the same series of papers on the nomenclature of the genera of pteridophytes with the exception of a few changes and additions.
Abstract: SUMMARY The publication of this series of papers on the nomenclature of the genera of pteridophytes was begun fifteen years ago under the general title of « Names and types of fern genera ». The first and second parts were issued in 1955 and 1957. This paper which deals with the living fern-allies belongs essentially to the same series. The plan of the work is fundamentally the same as in the previous papers with the exception of a few changes and additions. The remarks on the typification, nomenclature and taxonomy are given in separate paragraphs instead of in a single paragraph previously called « Observationes ». The synonymy is given in an independent paragraph. For each family a « Conspectus generum » is added, with the intent of giving a synoptic table of the nomenclatural and taxonomic interrelations of the various genera. The new sign: ≡ is introduced for nomenclatural synonyms by lectotypification. A part of the preface is devoted to the illustration of the criteria followed in the typification ...

TL;DR: It is proposed to reject both names of A. arcuata and A. congoensis as they constitute a source of error and because they can be interpreted as not validly published.
Abstract: Lectotypes are designated for three of the species of Ascotricha Berk, described by L. M. Ames ( A. arcuata, A. congoensis and A. guamensis ) and the holotype of A. xylina Ames is discussed. A study of Ames's specimens and original pencil drawings of A. arcuata and A. congoensis shows that in each instance the description and published illustration does not apply to the type material of the taxon it purports to describe, but that it actually applies to the type material of the other taxon. Because of the confusion between the concepts of A. arcuata and A. congoensis as published and those demonstrated by the type material and original pencil drawings it is proposed to reject both these names as they constitute a source of error (Art. 69) and because they can be interpreted as not validly published (Art. 32).

TL;DR: In revising Myrtaceae Blume correctly concluded in 1849 that Psidium rubrum Lour, from Indo-China could not belong to that neotropical genus, so it is desirable to select one of these two syntypes as the lectotype of the genus.
Abstract: In revising Myrtaceae Blume correctly concluded in 1849 that Psidium rubrum Lour, from Indo-China could not belong to that neotropical genus. He erected a new genus Macropsidium Bl., to accommodate it, adding at the same time the description of a second new species from the Moluccas.
It is desirable to select one of these two syntypes as the lectotype of the genus. I have chosen the one described by Loureiro, which procedure deserves the merit of saving also the generic name Octamyrtus Diels (Bot. Jahrb. 57, 1922, 373) to which I believe Blume’s second species belongs. This leads to the following formal nomenclatural and taxonomic disposition.
