“…Only four Triglochin spp. in Juncaginaceae ( Triglochin striata Ruiz & Pav., T. elongata Buchenau , T. buchenaui Köcke, Mering & Kadereit and T. palustris L.) form elongate rhizomes or stolons with cataphylls (Buchenau, ; Aston, , ; Lieu, ; Tomlinson, ; Köcke et al ., ). In contrast with Maundia , these species show shoot dimorphism, as some shoots are short and possess foliage leaves only.…”

Vegetative morphology and anatomy ofMaundia(Maundiaceae: Alismatales) and patterns of peripheral bundle orientation in angiosperm leaves with three-dimensional venation

et al. 2016

Collateral bundles with external position of the phloem characterize the stem vasculature of most seed plants. An earlier study highlighted the occurrence of inverted peripheral bundles in the leafless inflorescence peduncle of the rare Australian aquatic Maundia triglochinoides. This unusual feature and other morphological and molecular data supported the recognition of the monogeneric Maundiaceae, but the anatomy of the leaves, rhizomes and roots of Maundia remained unknown and is studied here. Maundia has an iterative sympodial growth with all shoots bearing five tubular cataphylls splitting longitudinally and simulating open sheaths at maturity and two (or three) linear foliage leaves without a conspicuous basal sheath. This morphology distinguishes Maundiaceae from all other Alismatales. The rhizome has an atactostele with collateral bundles of normal orientation; peripheral bundles are absent. Cataphylls have a series of normally oriented bundles. Foliage leaves are thick, bifacial, semi‐elliptical in cross‐section, with a thin subepidermal layer of chlorenchyma on both sides, accompanied by peripheral bundles with xylem facing outwards (thus abaxial peripheral bundles are inverted) and central large bundles of normal orientation. Strong anatomical similarity between leaves and peduncles is related to their shared function as assimilatory organs. As in angiosperm succulents, the three‐dimensional leaf venation in thick aquatic and helophyte leaves of Alismatales serves to reduce transport distances between veins and photosynthetic cells. In both cases, the patterns of orientation of peripheral bundles (with inverted adaxial or abaxial bundles) are unstable in large clades. These slender bundles cannot be used for the identification of unifacial leaves. Some anatomical characters express homoplastic similarities between Maundiaceae and Aponogetonaceae.

“…However, we have found original material with the same collector ("Pérez Camarero"), date ("Primavera de 1914") and locality ("Larache") indicated in Font Quer's publication in MA and BC herbaria (although they are labelled only as "Triglochin barrelieri "). Being that the specimen proposed by Köcke & al. (2010) was collected 16 years after the taxon was published and original material exists, this lectotypification is not correct.…”

“…The BC specimen also has a revision label by Mering who re-determined it as Triglochin barrelieri Loisel. According to Köcke & al. (2010), this species is very variable in overall size and fruit and pedicel length, and includes also plants with long pedicels and big fruits, the distinctive characters of T. barrelieri var.…”

ResumoO presente estudo tem como objetivo contribuir para o conhecimento das espécies de Juncaginaceae ocorrentes no estado do Rio de Janeiro. O trabalho tem por base a análise morfológica de materiais depositados em herbários e trabalho de campo, além da compilação de dados de literatura. Foi registrado um gênero com uma espécie: Triglochin striata. Descrições, ilustrações, dados sobre hábitat, fenologia e distribuição geográfica são apresentados. Palavras-chave: florística, plantas paludosas, taxonomia, Triglochin. AbstractThis study focuses on the Juncaginaceae found in the state of Rio de Janeiro. It is based on a morphological analysis of herbaria collections, as well as on a review of the relevant literature and field work. A total of one species were recorded for the state: Triglochin striata. Descriptions, illustrations, habitat data, phenology, and species distribution are also provided. Ervas perenes ou anuais, frequentemente aquáticas, glabras. Rizoma presente ou não, curto, subterrâneo, ereto, geralmente cilíndrico e estolonífero. Folhas alternas dísticas ou espiraladas, simples, basais e sésseis; lígula frequentemente presente no ápice da bainha. Inflorescência em espiga ou racemo. Flores uni ou bissexuais, actinomorfas ou raramente zigomorfas, prefloração valvar; tépalas (0-)1-6 em 1-2 verticilos, livres, inconspícuas; estames 0-6, livres, férteis ou abortivos; anteras sésseis ou subsésseis, adnatas à base das tépalas, rimosas e basifixas. Ovário súpero, 1-2-4 locular, 1-6 carpelar, geralmente uniovulado; carpelos livres ou conados; placentação basal; estiletes curtos, longos, filiformes ou ausentes; estigmas papilosos ou fimbriados. Fruto folículo, aquênio ou núcula, semente linear ou ovoide.Família representada por quatro gêneros e ca. 15 espécies de distribuição subcosmopolita (Haynes et al. 1998;Pansarin & Amaral 2003).No Brasil ocorrem dois gêneros e duas espécies, distribuindo-se pelo Sul e Sudeste. No Rio de Janeiro está representada por uma espécie (BFG 2015).
