<i>Ipomoea cristulata</i> Hallier f. (Convolvulaceae), native to the desert regions of central USA Mexico, was newly found in Gojeong-ri, Deokgwa-myeon, Namwon-si, Jeollabuk-do. This species can be distinguished from <i>I. coccinea</i> by leaves with 3-5 lobes, hirsute distributed adaxially, and corolla entirely red or orange-red. Its Korean name is ‘Na-bi-ip-yu-hong-cho...

The herbaceous perennial species in the genus Sphaeralcea have desirable drought tolerance and aesthetics with potential for low-water use landscapes. However, taxonomy of these species is ambiguous, which leads to decreased consumer confidence in the native plant industry. The goal of this study was to test and clarify morphological and genetic differentiation among four putative species. Morp...

During 2011, twigs, leaves and fruits of symptomatic hosts containing Fusicladium species from Guilan, Mazandaran, Qazvin and Ardabil provinces were sampled and examined. Five species including F. carpophilum, F. fraxini, F. oleagineum, F. pomi and F. pyrorum were identified based on morphological data. Of these, F. carpophilum and F. fraxini are identified as new records for the mycobiota of I...

Full citations of animal specific or generic names ultimately derived from unpublished manuscripts should commemorate the work of the person who described the new species as well as the person who eventually validly published the name. We suggest that biologists should use the following authorships when citing these names: Terebella infundibulum Renier in Meneghini, 1847 (now used in the genus ...

We examined the genetic basis of resistance to the rust pathogen Coleosporium ipomoea in three host species: Ipomoea purpurea, I. hederacea, and I. coccinea (Convolvulaceae). In crosses between resistant and susceptible individuals, second-generation selfed offspring segregated in ratios that did not differ statistically from the 3:1 ratio indicative of single-gene resistance with the resistant...
