REINWARDTIA published by Herbarium Bogoriense - LBN. Bogor Vol. 10, Part 2, pp. 115 — 117 (1085) AEGOPOGON (GRAMINEAE) IN MALESIA J. F. VELDKAMP Kijksherbarium; Leiden, the Netherlands ABSTRACT AeyopoyoiL ceucliroides Willd. var. cenchroides is recorded for the first time from Malesian area based on a collection from Mt. Michael (Papuu New Guinea). A description is provided. ABSTKAK Aegopogou cenchroides Willd. var. emtchrvkles direkam untuk perfcamu kali dari Kawasan Malesia, berdasarkan koleksi dari Gummg Michael 'Papua Nugini). Sebuah pertelaan disajikan. In June 1979 Mr. K. Kerenga, Lae, Papua New Guinea, visited the summit of Mt, Michael, ca. 3750 m high. Among his collections was a curious grass (LAE 74443), .said to cover large areas by sprawling, which has turned out to be Aegopogon cenchroides Willd. var. cenchroides. Neither the species, not the genus was so far known from Malesia, and as I think existing descriptions may not always be within reach of Malesian botanists a short generico-specific description is given here based on the New Guinea collection. The plant is especially conspicuous for the one-sided panicle with paired, much-bristled spikelets that drop off as small burs. The genus of three species is restricted to subtropical America, while our species occurs from Northern Mexico to Bolivia and Venezuela. This distribution would seem to make introduction hardly likely on a mountain only rarely visited by local people and even less outsiders. The latter would be mainly Australian, but the genus has not yet been reported from that continent (Simon in Techn. Bull. Bot. Br. Dept. Prim. Industr., Brisbane 3: 1—89. -

The presence of genome-specific introgression; wheat diagnostic alleles in natural populations of the barbed goatgrass hybridization; growing in proximity to cultivated fields highlights that substantial gene mapped EST-SSR; flow occurred when both species coexisted. Furthermore, loci from the A transgene escape. subgenome of wheat were significantly less introgressed than sequences from other subgenomes, indicating differential introgression into Ae. triun- cialis. Gene flow between such species sharing nonhomeologous chromo- somes addresses the evolutionary outcomes of hybridization and may be important for efficient gene containment. have been reported in European agro-ecosystems Introduction (Felber et al., 2007).

Gopher–Plant–Fungal Interactions Affect
Ecology, 84(1), 2003, pp. 120±128 q 2003 by the Ecological Society of America GOPHER±PLANT±FUNGAL INTERACTIONS AFFECT ESTABLISHMENT OF AN INVASIVE GRASS VALERIE T. E VINER1,3 AND F. S TUART CHAPIN, III2 1Department of Integrative Biology, University of California, Berkeley, California 94720 USA 2Institute of Arctic Biology, University of Alaska, Fairbanks, Alaska 99775 USA Abstract. Many attempts have been made to link invasions of exotic plants to speci®c plant traits and key attributes of invaded ecosystems. While these factors play a role in determining the potential for invasion, they are often inadequate in predicting the success of a speci®c invasion. We show that interactions of an invasive grass with other members of the community determine the local pattern of invasion. A fungus, Ulocladium atrum, aids the establishment of barbed goatgrass (Aegilops triuncialis) by weakening the grass's tough seed head, thereby accelerating germination and seedling establishment. In contrast, gophers, Thomomys bottae, decrease establishment of this invader by selectively burying patches of goatgrass seedlings under mounds. Plants that survive these gopher disturbances produce seeds that are uninfected by Ulocladium atrum, which may further decrease the establishment of the next generation of goatgrass. A ®eld survey indicated that goatgrass achieves dominance in areas with minimal gopher disturbance, but has limited establishment in pastures with high gopher activity, indicating that the landscape pattern of gopher activity in¯uences patterns of goatgrass invasion by manipulating gopher±plant±fungal interactions. Key words: Aegilops triuncialis; California (USA) annual grasslands; disturbance; fungus; ger- mination; goatgrass; plant invasion; pocket gophers; species interactions, role in plant invasion; Thomomys bottae; Ulocladium atrum. -

18 New Nothogenera and 8 New Combinations in the Grass Family Poaceae
CACTOLOGIA PHANTASTICA 3(2) 4 FEB 2019 10 ISSN 2590-3403 DOI 10.5281/zenodo.2556225 18 New Nothogenera and 8 New Combinations in the Grass Family Poaceae By MAARTEN H. J. VAN DER MEER The grass family Poaceae includes major crop genera like Triticum (wheat), Hordeum (barley) and Secale (rye) in the subfamily Pooideae, and Saccharum (sugarcane), Sorghum (sorghum) and Zea (maize) in the subfamily Panicoideae. Species from this family have been used for extensive hybridization experiments. No less than 59 valid nothogenera are listed in IPNI, yet dozens of intergeneric hybrids remain nameless.1 Notho- generic names are proposed here for eighteen intergeneric hybrids, including one tetrageneric hybrid, ten trigeneric hybrids and seven bigeneric hybrids. In addition, seven new combinations for nothospecies are proposed.

The ‘needlegrasses’ are char- acterized by having single-flowered spikelets and stout, terminally-awned lem- mas. We conducted a molecular phylogenetic study of the Stipeae (including all genera except Anemanthele) using a total of 94 species (nine species were used as outgroups) based on five plastid DNA regions (trnK-5’matK, matK, trnHGUG-psbA, trnL5’-trnF, and ndhF) and a single nuclear DNA region (ITS). -
Water Relations of Bromeliaceae in Their Evolutionary Context
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Apollo Botanical Journal of the Linnean Society, 2016, 181, 415–440. With 2 figures Think tank: water relations of Bromeliaceae in their evolutionary context JAMIE MALES* Department of Plant Sciences, University of Cambridge, Downing Street, Cambridge CB2 3EA, UK Received 31 July 2015; revised 28 February 2016; accepted for publication 1 March 2016 Water relations represent a pivotal nexus in plant biology due to the multiplicity of functions affected by water status. Hydraulic properties of plant parts are therefore likely to be relevant to evolutionary trends in many taxa. Bromeliaceae encompass a wealth of morphological, physiological and ecological variations and the geographical and bioclimatic range of the family is also extensive. The diversification of bromeliad lineages is known to be correlated with the origins of a suite of key innovations, many of which relate directly or indirectly to water relations. However, little information is known regarding the role of change in morphoanatomical and hydraulic traits in the evolutionary origins of the classical ecophysiological functional types in Bromeliaceae or how this role relates to the diversification of specific lineages. In this paper, I present a synthesis of the current knowledge on bromeliad water relations and a qualitative model of the evolution of relevant traits in the context of the functional types. I use this model to introduce a manifesto for a new research programme on the integrative biology and evolution of bromeliad water-use strategies. The need for a wide-ranging survey of morphoanatomical and hydraulic traits across Bromeliaceae is stressed, as this would provide extensive insight into structure– function relationships of relevance to the evolutionary history of bromeliads and, more generally, to the evolutionary physiology of flowering plants. -
