Phylogenetic Studies

This work presents a new circumscription and a taxonomic treatment for Chamaecrista ser. Setosae that resulted from previous phylogenetic studies and the analysis of ca. 350 collections, including typus, as well as the observation of populations in field. Nine species were recognized for the series, eight of which are endemic to Brazil, and one firstly recorded for the country (Ch. orenocensis). Are proposed the synonymizations of all varieties of Ch. setosa, the transfer of Ch. amphibola from the Setosae series to the ser. Ursinae and its consequent synonymization under Ch. exsudans, and the inclusion of Ch. multiseta from the Absoideae series to the ser.  Setosae based on previous phylogenetic and morphological evidences. Species are contrasted in a key, with their updated typifications, represented through images and described and commented on their flowering and fruiting periods, their geographical distributions, including, maps, preferred environments and conservation status, morphological relationships, as well as illustrated by their diagnostic characters.

Abstract We present the taxonomic treatment of Convolvulaceae for the Meruoca Massif, located in the Northwest region of the Ceará state, where there are remnants of Tropical Pluvial Sub-deciduous Forest (Dry Forest) and Tropical Pluvial-Nebular Rainforest (Wet Forest). The present study was based on the morphological analysis of specimens collected in the field and from the collections EAC, HUEFS, HUVA, PEUFR, and SPF. We recorded 24 species distributed in four genera: Ipomoea (18 species), Jacquemontia (three species), Distimake (two species), and Camonea (one species). We report the first records of I. cearensis for Atlantic Forest and I. aristolochiifolia to the state of Ceará. The taxonomic treatment includes identification key, morphological descriptions, geographic distribution, taxonomic and ecological comments, the period of flowering and fruiting, and photos and illustrations of the diagnostic characters.

Taxonomic Treatment

Anupdated circumscription and a taxonomic treatment of Chamaecrista sect. Absus subsect. Absus ser. Rigidulae is presented based on the results of previous phylogeny study where the series has emerged as monophyletic with exclusion of two species (C. brachyblepharis and C.ciliolata) and inclusion of two others species (C. botryoides and Ch. sincorana) in its circumscription. This revision resulted from consulting the specialized literature, analyzing of about 1400 collections from national and foreign herbaria. In this new circumscription, the series becomes the largest series of the genus with 32 species endemics to Brazil and distributed mainly in the Brazilian Central Plateau. Two new records in Brazilian states were reported, one to Bahia (Ch. feliciana) and two to Minas Gerais (Ch. benthamiana, Ch. rupestrium); an identification key of the species, morphologic descriptions, notes on taxonomy and geographic distribution of the taxa, conservation status, as well as illustrations and images of diagnostic characters are presented. In addition, the species typification remains updated with all categories indicated first with their respective barcodes.

Species of Ophiopogon Ker-Gawl (aztec grass, monkey grass, mondo grass, and snake's beard) are versatile, evergreen, grass-like perennials used in a variety of landscape situations. The nursery/landscape industry commonly recognizes the Ophiopogon species O. japonicus (Linn. f.) Ker-Gawl and O. plansicapus Nakai, with O. clarkei Hook. f., O. intermedius D. Don, O. graminifolius (L.) Wehrh., O. jaburan (Sieb.) Lodd., O. kansuensis Bat., and O. ohwii Okuyama available, but often misidentified and marketed under other names. Additional taxa are being introduced through botanic gardens and plant expeditions by horticulturists. A taxonomic treatment by the author of liriopogons cultivated in the southeastern United States had been in progress for nearly 15 years. Plants bearing the name O. graminifolius included additional misidentified species of Liriope Lour. and Ophiopogon. Plants bearing the name O. chingii Wang and Chang did not bear inflorescences, but vegetatively appear to be equivalent to O. graminifolius. Plants bearing the name O. mairei H. Lév. and O. wallichianus (Kunth) J.D. Hook. were misidentified as Liriope exiliflora (L.H. Bailey) H.H. Hume. Additional taxa available in botanic gardens included O. bockianus Diels., O. bodnieri H. Lév., O. checkiangensis Koiti Kimura and Migo, O. chingii, and O. marmoratus Pierre ex L. Rodr. Plants bearing the name O. parviflorus (Hook. f.) Hara died without producing reproductive structures; thus, identification to even genus was unattainable. Ophiopogon arabicus Hort., O. nigra Hort., and O. nigrescens Hort. were invalid names used in the trade for O. planiscapus. This treatment includes original morphological descriptions from data obtained in the study, observational notes, and a table with a key to segregation of taxa.

Ecological Information

This study presents a taxonomic revision of the Pteronia adenocarpa group. Six species are recognised within this group, namely P. adenocarpa, P. armatifolia, P. elongata, P. hutchinsoniana, P. stoehelinoides and P. viscosa. The group is distinct in its characteristic basally hairy cypselae, as opposed to the glabrous-glossy, glandular and/or variously hairy cypselae with the hairs evenly distributed throughout the surface found in the remaining species of the genus. We here present a detailed taxonomic treatment with descriptions, nomenclature, diagnostic characters, geographical distribution and maps, ecological information as well as the key to the species.

A New Species

A new genus and a new species, Haplodendron buzwilsoni, from the southeastern Australian mid bathyal are described. This is the first record of the family in the Southern Hemisphere IndoPacific. Diagnostic characters of the new genus are compared with those of other genera in the family. The possible significance of the joint possession, between the new genus and Dendrotion (Dendrotiidae), of a stalk carrying the antennulae and antennae is discussed. New observations on male reproductive structures are made.

The advantages of freeze substitution fixation over conventional chemical fixation for preservation of ultrastructural details in fungi have been discussed by various authors. As most ascomycetes, basidiomycetes and deuteromycetes do not fix well using conventional chemical fixation protocols, freeze substitution has attracted the attention of many individuals interested in fungal ultrastructure. Thus far most workers using this technique on fungi have concentrated on thin walled somatic hyphae. However, in our laboratory we have experimented with the use of freeze substitution on a variety of fungal reproductive structures and spores with promising results.Here we present data on freeze substituted samples of sporangia of the zygomycete Umbellopsis vinacea, basidia of Exobasidium camelliae var. gracilis, developing teliospores of the smut Sporisorium sorghi, germinating teliospores of the rust Gymnosporangium clavipes, germinating conidia of the deuteromycete Cercosporidium personatum, and developing ascospores of Ascodesmis nigricans.Spores of G. clavipes and C. personatum were deposited on moist pieces of sterile dialysis membrane where they hydrated and germinated. Asci of A. nigricans developed on pieces of dialysis membrane lying on nutrient agar plates. U. vinacea was cultured on small pieces of agar-coated wire. In the plant pathogens E. camelliae var. gracilis and S. sorghi, a razor blade was used to remove smal1 pieces of infected host issue. All samples were plunged directly into liquid propane and processed for study according to Hoch.l Samples on dialysis membrane were flat embedded. Serial thin sections were cut using a diamond knife, collected on slot grids, and allowed to dry down onto Formvar coated aluminum racks. Sections were post stained with uranyl acetate and lead citrate.

Formerly Cnemidophorus was thought to be the most speciose genus of Teiidae. This genus comprised four morphological groups that were later defined as four different genera, Ameivula, Aurivela, Cnemidophorus and Contomastix. The last appears as paraphyletic in a recent phylogenetic reconstruction based on morphology, but monophyletic in a reconstruction using molecular characters. Six species are allocated to Contomastix. One of them, C. lacertoides, having an extensive and disjunct geographic distribution in Argentina, Uruguay and Brazil. Preliminary analyses revealed morphological differences among its populations, suggesting that it is actually a complex of species. Here, we describe a new species corresponding to the Argentinian populations hitherto regarded as C. lacertoides, by integrating morphological and molecular evidence. Furthermore, we demonstrate that the presence of notched proximal margin of the tongue is a character that defines the genus Contomastix.
