Five new species of Thripidae (Thysanoptera) endemic to New Zealand

Abstract

Three new species of genus Thrips are described—austellus, coprosmae, and phormiicola—which are closely related to the common New Zealand species T. obscuratus (Crawford). The systematic and zoogeographic significance of this endemic species-group is discussed. Physemothrips hadrus n.sp. is described from the South Island; the only other member of this genus is from Macquarie Island. Anaphothrips zelandicus n.sp. is described from the South Island and the Chatham and Antipodes islands, A. woodi Pitkin is recorded from New Zealand, and the relationships of these two species to the Australian fauna are discussed.

Dilleniaceae Novae Neotropicae VIII. Two new species of Davilla from Brazil

Two new species of the genusDavilla from Brazil are described and illustrated (D. kubitzkii andD. morri). The new species are assigned to sect.Homalochlaena and their relationships with allied species are discussed.     

New species and a new combination in Myrtaceae from northeastern South America

Three new species of Myrtaceae (Calyptranthes bracteata, Eugenia gonglycocarpa, andMyrcia rupta) from northeastern South America are described and illustrated, and a new combination (Eugenia tetramera) is proposed. The closed-calyx and the completely or partially fused cotyledons ofMyrcia rupta, unusual features for the genus, are discussed and compared with related species inMyrcia andMarlierea.

Two new species of Alstroemeria L. (Alstroemeriaceae) from Brazil

Alstroemeria hygrophila andA. orchidioides are both described as new from the state of Goiás (including Distrito Federal) in Brazil.Alstroemeria hygrophila is a cerrado bog-dwelling species that grows semi-epiphytically on the culms of a sedge. The vegetative stems of this species characteristically zig-zag between the pseudonodes. Like other wetlandAlstroemeria in Brazil (e.g.,A. apertiflora, A. isabellana, andA. sellowiana),A. hygrophila has wiry stems bearing narrow, lanceolate, nonresupinate leaves, and does not form root tubers.Alstroemeria orchidioides is a hysteranthus forest understory species with large vegetative leaves aggregated at the apex of the stems. The leaves on flowering stems are reduced to scarious bract-like scales. Its flowers are a pale, nearly white, greenish yellow, a color not reported in any other Brazilian species. Both species have 2n=16 chromosomes.     

Two new species of Myrsinaceae from French Guiana

Herbarium studies leading to a treatment of the Myrsinaceae for the Flora of Central French Guiana resulted in the discovery of two heretofore undescribed species,Cybianthus prevostiae andStylogyne incognita. The species are described and illustrated, and hypotheses regarding phylogenetic relationships with their respective congeners are provided.Cybianthus prevostiae is unusual among members ofCybianthus subgen.Weigeltia owing to its monoaxial habit and ellipsoid pistil, and deeply cupuliform calyx.Stylogyne incognita, a taxon often confused withS. micrantha, is most closely related toS. sordida but is separated from it by the corymbose inflorescence, entire leaves, longer petioles, and membranaceous perianth.     

A new species of Tzeltalia (Solanaceae) from Mexico

A new species of Tzeltalia (Solanaceae) from Chiapas, Mexico is described and illustrated: Tzeltalia esenbeckii. A key and a table, distinguishing the members of the genus, are included.     

Two new species of Mimosa (Fabaceae) endemic to Bolivia

Two new species ofMimosa are described:M. woodii (sect.Mimosa), from the central Andean valleys of Bolivia, andM. suberosa (sect.Habbasia), from Serranía Huanchaca in the Noel Kempff National Park in the north east of Santa Cruz Department in eastern Bolivia. The affinities of each are discussed, their distributions mapped, and both species are illustrated.     

Review of the neotropical endemics Burmeistera, Centropogon, and Siphocampylus (Campanulaceae: Lobelioideae), with description of 18 new species and a new section

Burmeistera, Centropogon, and Siphocampylus together comprise more than 500 species endemic to the Neotropics, Current knowledge of these genera is unsatisfactory, with much diversity yet to be described. Over the past seven years, one out of every 28 specimens received for identification has represented a new species, many characterized by unique or unusual character states. Siphocampylus smilax (Bolivia) is unique in the genus in its parallelodromous leaf venation and extra-floral nectaries. Centropogon dianae (Peru) cannot be accommodated in any recognized infrageneric taxon, and a new section, Centropogon sect. Niveopsis, is proposed for it. The flowers of C. steinii (Ecuador) are the smallest known in the genus, while C. connatilobatus (Venezuela) is the first species to combine arbusculiform pubescence and connate calyx lobes. Burmeistera venezuelensis is only the second species of the genus known to occur in Venezuela and the first to be endemic; similarly, Centropogon wilburii is only the third species of Centropogon known from Mexico and the first to be endemic to that country. Additional novelties are also described.     

Pyrus ciancioi (Rosaceae), a new species from Sicily

Abstract

A new species of Pyrus L. from the Nebrodi Mountains (northeast Sicily) is described, named, and illustrated. It differs from Pyrus spinosa in the shape and diameter/length ratio of its fruits and in the width/length ratio of the leaf lamina. An analytical key to the Pyrus species growing in Sicily is provided.     

Two new species of Cololejeunea from Peninsular India

Abstract

Two new species of Cololejeunea (sub-genus Lep tocolea), C. pandei sp. nov. and C. dentifolia sp. nov. are described from fudia. Both species are epiphyllous with ascending leaves. The former is characterized by uniseriate stylus, serrated margin of leaf, discoid gemmae on ventral surface of leaf-lobe with 2-3 mamillose cells and inflated perianthwith lateral winged plicae. The latter is characterized by dentate margin of leaf, leaf-cells with distinct trigones and intermediate nodular, thickenings, bidentate leaf-lobule and discoid gemmae with 4 mamillose cells.     

Jacquinia pauciflora (Theophrastaceae), a new species from Puerto Rico

A new species,Jacquinia pauciflora, is described from subtropical moist forest on karst hills (mogotes) in northwestern Puerto Rico.Jacquinia pauciflora is similar toJ. stenophylla Urban, from which it differs in several floral and leaf characters, but is possibly most closely related toJ. umbellata A. DC. A key to the species ofJacquinia occurring in Puerto Rico is provided.     

Distichochlamys rubrostriata (Zingiberaceae), a new species from northern Vietnam

A third species of the until recently monotypic genusDistichochlamys (Zingiberaceae) is described from living and preserved material collected in northern Vietnam.Distichochlamys rubrostriata is distinguished from the original species,D. citrea, and the recently describedD. orlowii, on the basis of leaf, inflorescence bract, lateral staminode, and labellum characters.     

Four new species Of Mexican Castilleja (subgenus Castilleja,Scrophulariaceae) and their relatives

Castilleja subgenusCastilleja in the northern half of Mexico consists of nine species, which are treated here. The subgenus is characterized by a conspicuously colored calyx that is much more deeply cleft in front (abaxially) than in back (adaxially).Castilleja rhizomata,C. linifolia,C. mcvaughii, andC. pterocaulon are described as new, and are illustrated and mapped. The first three are compared toC. patriotica and C.tenuiflora, their closest relatives in the Tenuiflorae group, and the fourth is compared toC. ortegae, with which it constitutes the Ortegae group.Castilleja roei andC. tenuifolia of the Epichroma group are included in order to complete the census of subgenusCastilleja as encountered in the region of the new species. A key to the nine species of subgenusCastilleja from the northern half of Mexico is provided.
