Chaconia hennenii is proposed as a new holomorph species for Uredo maclurae (= Physopella maclurae) on Maclura tinctoria (Moraceae) after the discovery of teliospores. Uredo celtidis described on Celtis (Ulmaceae) is synonymous with U. maclurae and belongs to the same holomorph species, as revealed by morphologically indistinguishable urediniospores and newly discovered teliospores. The host genus of U. celtidis is not Celtis, but most probably Maclura, too. Chaconia hennenii is unique among known Chaconia species by the apical wall thickening of the teliospores.  相似文献

Summary Two new species of the dacetine ant genusKyidris from New Guinea are described. These were always found in mixed colonies with the larger, polymorphic dacetine speciesStrumigenys loriae Emery, which often occurs independently and is generally abundant in the lowland rain forests of New Guinea. The relationship of theKyidris to theStrumigenys is interpreted as a very primitive level of permanent, obligatory, nondulotic parasitism. Multiple queens of both genera occur together, and the brood is completely mixed. The worker population of the parasite is very large, and in one colony studied almost equaled that of the host. The parasite workers contribute to the colony labor by food-gathering and brood-handling, but are relatively inefficient in these tasks; they apparently do not participate in nest building at all.
Résumé Cet article décrit deux espèces nouvelles deKyidris de la Nouvelle Guinée, genre de fourmis dacétines. Elles ont été trouvées toujours en colonies mixtes avecStrumigenys loriae Emery, grande dacétine polymorphe vivant souvent sans son parasite et commune partout dans les forêts humides tropicales à basse altitude de la Nouvelle Guinée. Les relations entreKyidris etStrumigenys sont interprétées comme un stade primitif de parasitisme permanent, obligatoire et non-dulotique. De nombreuses reines des deux genres se trouvent ensemble dans le même nid, et leur couvain est complètement mélangé. Les ouvrières du parasite sont très nombreuses et, dans une des colonies étudiées, étaient presque aussi nombreuses que celles de l'hôte. Les ouvrières contribuent au travail de la colonie en recueillant de la nourriture et en soignant le couvain, mais d'une façon relativement inefficace; elles ne paraissent pas participer à la construction du nid.

A total of 105 plants used for food and medicine and 11 animals hunted and gathered for meat by the Khasis and Garos of Meghalaya were identified. Of the total plants recorded, 85 were used by the Garos alone, only three by the Khasis whereas the other 17 were used by both tribes. In addition to fresh use in-season many plant products were processed for storage and use off-season. Although all adults were familiar with various uses of plants and animals, the village elders were more knowledgeable. Garos have especially knowledgeable curers. Wild foods are of particular value for tiding over lean periods when resources from agriculture and animal husbandry systems are scarce, especially for the poorer sections of society. The importance of recording the use of plants and animals in this region is especially important because of rapid loss of rain forest habitats.  相似文献

Cup fungi of Ani-jima Island, the Bonin Islands, were collected in November 1990 and described for the first time from Ani-jima Island. Four species,Dicephalospora rufocornea, Lachnum abnormis, Lachnum pritzelianum, andOrbilia delicatula were collected from the materials in the litter layer ofLivistona chinensis var.boninensis community around Mt. Kita-hutago in Ani-jima Island.Pulvinula globifera was collected from the soil under a camellia (Schima mertensiana) community to the southeast of Mt. Kita-hutago.Lachnum pritzelianum was new to Japan.  相似文献

Information onC. arizonica, C. hapalocarpa, C. mcvaughii, C. parviflora, andC. pectinata published in a monograph of the genus in 1983 is updated. The generic affinities ofC. myriantha andC. sinaloensis are resolved, with the former placed inCarlowrightia and the latter removed to a separate genus. The new combinationC. neesiana, necessitated by conservation of the generic nameCarlowrightia, is provided for the species previously known asC. glandulosa. Two new species from western Mexico,C. fuertensis andC. huicholiana, are described, mapped, and illustrated.  相似文献

The taxonomic status of some Chilean Cruciferae is elucidated, and new combinations in the genera Stenodraba Sch. and Hollermayera Sch. are established. Additionally a new section, Elatia , and two specific names to replace illegitimate binomials in Stenodraba are proposed.  相似文献
