Ten rust species are reported with new information on range of distribution and host relations. Among these, Puccinia fagopyricola and Uromyces junci were new to Japan, and Aecidium araliae was newly found in northern Honshu. Additional collections were made of Blastospora smilacis, Puccinia malvacearum and P. orbicula in northern Honshu. New hosts were added to Coleosporium solidaginis, C. tussilaginis, Phragmidium miyakeanum and Puccinia caricis, and a new Japanese host to Puccinia malvacearum.V: Trans. Mycol. Soc. Japan 29: 471–478, 1988. 相似文献

Castilleja chambersii is described from several collections made in the Coast Range of southwestern Clatsop County, Oregon. The new species is
a member of subgenus Castilleja and is most closely related to C. parviflora and C. rupicola. This rare species is known from only three small and geographically restricted populations. Two new meiotic chromosome counts
of n=12 are reported for the new species. 相似文献

Two new species are added to Cryptochloa, C. unispiculata from Peru and C. capillata from Brazil, the latter transferred from the genus Olyra. The genus Piresia is also augmented by two new species, P. macrophylla from Peru and P. leptophylla from Bahia, Brazil. These species represent, respectively, the westernmost and easternmost limits of distribution of the genus. 相似文献

Two new species of Sisymbrium are described from the Department of Arequipa in south-western Peru. Both are annuals from the loma vegetation. Sisymbrium lactucoides has glabrous leaves with clasping bases and is very distinct. Sisymbrium ferreyrae is probably closest to S. llatasii, but it is a much smaller plant with petals and sepals of subequal length (vs. petals longer than sepals in S. llatasii). 相似文献

Summary A survey was made of the yeasts occurring in the intestinal tract of wild species of Drosophila occurring in the Yosemite Region of California. Two hundred and forty one yeasts, representing 42 species and varieties,
were identified. Each isolate was obtained from a different fly. Almost half of the isolates belong to Saccharomyces. The most common species in this genus were S. montanus (36 isolates), S. veronae (30 isolates), S. cerevisiae var. tetrasporus (22 isolates) and S. drosophilarum (13 isolates). Further species are listed in Table 1. Zygosaccharomyces fermentati Naganishi was shown to be a distinct species and not a synonym of S. cerevisiae. In order to avoid confusion with another yeast of the same name, it has been proposed to change the name Z. fermentati to S. montanus Naganishi. Two new species of Saccharomyces were described, S. wickerhamii and S. kluyveri. S. mangini var. tetrasporus has been renamed S. cerevisiae var. tetrasporus. A non-cellobiose attacking strain of S. drosophilarum has been designated tentatively S. drosophilarum var. acellobiosa. A new species of the genus Pichia was described as P. xylosa. Saccharomyces pastori and Saccharomyces pini were transferred to the genus Pichia on the basis of arguments given in the preceding paper. A new species of Trichosporon was described as Tr. aculeatum on the basis of the presence of characteristic needlelike cells. Common species besides those mentioned in Saccharomyces were Hansenula angusta (19), Kloeckera apiculata (15), Kl. magna (13), and Torulopsis stellata (10). Other genera represented were Hanseniaspora, Cryptococus, Rhodotorula, Candida and Oospora. Evidence was obtained that many species of imperfect genera consist of distinctly different physiological types. 相似文献

The genusSabazia is expanded to include the genusTricarpha, Calea palmeri, and several newly described taxa,S. tridacoides var.tridacoides and var.latifolia, S. palmeri var.lancifolia, andS. longiradiata. Comparative studies of several morphological features suggest thatSabazia is most clearly related toSelloa andGalinsoga. Karyological data reinforce this observation: inSelloa andGalinsoga x = 8 whereas inSabazia x = 4 andn = 4, 8, 16, or 24. Several species ofCalea are very similar toSabazia in floral features and may be of close phyletic affinity, but most species ofCalea differ conspicuously, suggesting more remote relationships. Other taxa in the Galinsoginae apparently fairly closely allied toSabazia includeOteiza andTridax. 相似文献

Lectotypes are designated for Amanoa caribaea Krug & Urban and A. guianensis Aublet; presumed syntypes of the latter taxon are shown to be heterogeneous by inclusion of a previously unrecognized species.
Four new species of Amanoa are described: A. congesta from French Guiana and northeastern Brazil; A. gracillima from Manaus, Brazil; A. nanayensis from Amazonian Peru and adjacent Colombia and Brazil; and A neglecta from French Guiana and Surinam. Amanoa sinuosa is proposed as a new name for the later homonym A. robusta Leal. A key to the 13 neotropical species is presented. 相似文献

The following species, originally described in the genus Saracha Ruiz & Pav., are transferred to Jaltomata, in accordance with contemporary generic boundaries. Jaltomata auriculata (Miers) Mione is distributed from Venezuela to Peru; J. contorta (Ruiz & Pav.) Mione and J. diversa (J. F. Macbr.) Mione both occur in Peru; J. herrerae (C. V. Morton) Mione is distributed in Peru and Bolivia; J. nitida (Bitter) Mione occurs in Venezuela. 相似文献

During a research on gill ectoparasites of callichthyids fishes from the Peruvian Amazonia, the following monogenoideans were found: Philocorydoras peruensis n. sp. from Corydoras splendens (Castelnau); Philocorydoras multiradiatus n. sp. and Philocorydoras jumboi n. sp. from Brochis multiradiatus (Orcés, V.). All new species described herein are mainly differentiated from their congeners based on the morphology of the copulatory complex. In P. peruensis n. sp. the cirrus is “J”-like shaped tube slightly tilted to one side, while in P. jumboi n. sp. is “J”-like shaped tube in a straight position and in P. multiradiatus n. sp. the cirrus is an arced tube with inflated base and distally narrow. Brochis (Orcés, V.) represents a new genus hosting species of Philocorydoras. All new species presented in this work represent the first species of Philocorydoras reported for Peru. 相似文献

Pentaplaris davidsmithii from Peru and Bolivia and P. huaoranica from Ecuador are described and compared to the only other species previously known in the genus, P. doroteae from Costa Rica. Morphological and palynological characters support the inclusion of Pentaplaris in core Malvales while suggesting that the original assumption that the genus belonged in Tiliaceae-Brownlowieae cannot be
maintained. Pentaplaris, which comprises three isolated and evidently rare species, probably belongs to the malvoid-bombacoid alliance, but its position
within this clade ramains unresolved. 相似文献

Summary Eight monocentric fungi are reported in two provisionally identified species of Rhizosolenia from sea-water. Only two species are assigned specific names. These are Rhizophydium planktonicum
Canter and R. fragilariae
Canter. A fungus with depressed-globose sporangia is included as a form of R. fragilariae. Two unidentified species of Chytridium are reported. A fungus tentatively assigned to Zygorhizidium and a form provisionally assigned to Petersenia are also reported and described insofar as their characteristics are known. 相似文献

Deoxyribonucleic acids of 8 species of Kluyveromyces and one round-spored species of Pichia have been compared with P 32 labelled DNA of K. marxianus in view of a systematic study by a method of hybridization in liquid media.The species related to K. marxianus by currently employed systematic characters show generally a good nucleotide sequence homology (> 70%), except K. wickerhamii.On the contrary, K. africanus, K. phaffii and P. abadiae show a very low percentage of hybridization with K. marxianus.This molecular approach yields useful information to test the value of usual criteria of yeast systematic.

Luziola is a small genus from aquatic environments of the New World. The most widespread species in the genus is L. peruviana. Morphological variation has been documented for this species throughout its entire range of distribution, however this variation
has been difficult to characterize. A population aggregation analysis was performed in order to determine how many species
can be identified when analyzing characters from the individuals of this taxon as well as with individuals from closely related
taxa such as L. divergens, L. doelliana, and L. pittieri. Multivariate analysis, ANOVA and ANCOVA analyses were also performed to detect if quantitative morphological variation is
related to altitude and latitude. Results indicate that within this complex only one species should be recognized, referable
to L. peruviana, and that plants near the equator are larger, and have larger lemmas and paleas in both female and male flowers. An identification
key for the nine species now recognized in Luziola is included. 相似文献
