wavy leaved thistle, wavyleaf thistle Biota of North America Program 2014 county distribution map Flora of North America, Cirsium undulatum United States Department of Agriculture Plants Profile Louda, Svaa M. (wikipedia.org)
Wavyleaf thistle is listed by California as a noxious weed. (swbiodiversity.org)
Scariosum9
Cirsium undulatum is known to hybridize with C. flodmanii, C. hookerianum , and C. scariosum var. (swbiodiversity.org)
Cirsium scariosum is a widely distributed complex of intergrading races distributed from southwestern Canada to northwestern Mexico. (swbiodiversity.org)
F. Petrak (1917) recognized ten species plus several subspecies for the taxa I am treating here as C. scariosum (in the broad sense). (swbiodiversity.org)
The latter two species, while clearly related to C. scariosum , have a range restricted mostly to Canada. (swbiodiversity.org)
After consulting with A. Cronquist and studying his manuscript treatment of Cirsium for the Intermountain Flora , D. J. Keil and C. E. Turner (1993) also accepted a broadly construed C. scariosum . (swbiodiversity.org)
Cronquist (1994) treated C. scariosum as an extremely variable species that included the four species recognized by Moore and Frankton plus the variety proposed by Welsh. (swbiodiversity.org)
Genus1
Examination of the genitalia will readily determine the genus - the only confusion species is then H.nimbella which has almost identical genitalia to H.nebulella . (weebly.com)
Wildflowers1
These are a few of the many species of wildflowers decorating the surface at Jewel Cave National Monument. (nps.gov)
Flora2
Answers to key questions in Budd's Flora (BF) and Flora of Alberta (FOA) leading to this species. (colinherb.com)
Also included are just those answers from the species key in Flora of the Great Plains (FGP) which separate C. undulatum from C. flodmanii . (colinherb.com)
Flodmanii3
I find the key answers separating C. undulatum from C. flodmanii to be contradictory and not always correct. (colinherb.com)
The achene of C. flodmanii is brown and has a well-defined yellow apical band about 0.5 mm wide, while the achene of C. undulatum is more straw coloured and does not have a well-defined apical band. (colinherb.com)
All the answers which separate C. undulatum from C. flodmanii are written on a white background. (colinherb.com)
Canescens1
However, most reports of Cirsium undulatum in California are based upon misidentifications of C. canescens . (swbiodiversity.org)
Taxon1
This taxon has been designated by the California Department of Fish and Wildlife as a "Species of Special Concern" because a highly fragmented distribution and widespread threats have made them vulnerable to localized extinctions. (guadalupedunes.com)
Plants1
The Guadalupe Restoration Project is home to numerous threatened and endangered plants and animal species, as well as many species of special concern. (guadalupedunes.com)
Widespread2
Cirsium undulatum is widespread and found in many habitat types. (wikipedia.org)
Cirsium undulatum is widely distributed in the wstern half of North America from the dry plains and plateaus of the Pacific Northwest eastward across the Great Plains to Manitoba and the Dakotas and south to Texas, New Mexico, and northwestern Mexico. (swbiodiversity.org)
Cirsium eatonii is a polymorphic species widely distributed in a high elevation archipelago across the central Rocky Mountains and the Intermountain Region. (efloras.org)
Spiny1
The La Graciosa thistle is a short-lived (1-2 years), spiny member of the sunflower family with purple and white flowers that can grow up to three feet tall. (guadalupedunes.com)
Taxa1
A detailed study of this species might reveal races worthy of recognition as infraspecific taxa. (swbiodiversity.org)
ochrocentrum is also present in NM and AZ as well as the rest of the species- range, and has white, lavender, or purple corollas and long-decurrent leaf bases. (asu.edu)
Family1
It's a globally rare [G3] annual species of the borage family that flowers early in spring before senescing and disappearing by early summer. (blogspot.com)
Buckwheat1
The usual species are along the Upper Crossing Trail, notably White and Purple Prairie-clover, Scurf Pea, and James' Buckwheat. (inaturalist.org)
1883 (as eatoni), based on Cirsium eriocephalum A. Gray [not Wallroth] var. (efloras.org)
Occurs2
Surf thistle often occurs in the same areas as beach spectaclepod on the GRP and in 2018, the on-site population has ranged from 721 (in 2015) to a high of 5,225 (in 2010). (guadalupedunes.com)
The large number of specimens available has allowed me to examine distributional patterns in relation to the topography and biogeographic history of the regions where this species occurs. (swbiodiversity.org)
Plant species3
The actions required with regard to any plant species depend on the category in which the plant appears in Table 3 of the amended regulations, and might differ from province to province. (agric.za)
Plant species were included in this list for one or more of the following reasons: they might pose a serious health risk to humans or livestock, cause serious financial losses to land users, be able to invade undisturbed environments and transform or degrade natural plant communities, use more water than the plant communities they replace or be particularly difficult to control. (agric.za)
Within 14 days of your assessment, our Gardens for Wildlife Officer will provide you with a report featuring personalised garden advice, suggested plant species list and a planting location diagram. (vic.gov.au)
Sensitive Species1
Annual and periodic monitoring of sensitive species is a major component of the GRP, to ensure that remediation and restoration activities are not having negative effects on the local population. (guadalupedunes.com)
List2
This is a list of all of the Common Names of species that appear on this site. (ontariowildflowers.com)
There is also on this site a list of just the common names I have used to identify each species on this site (each species listed only once). (ontariowildflowers.com)
Races1
Several of the races recognized here as varieties have been treated in the past as species (e.g. (efloras.org)
Populations2
During Pleistocene glacial episodes, the progenitors of this species complex undoubtedly occupied lower elevation sites and likely had more contiguous populations. (efloras.org)
Also known as Pennsylvania wild pink, it's a state threatened species here in Ohio with most extant populations clustered in Columbiana and Jefferson counties. (blogspot.com)
Bird1
This showy blue wildflower is desirable for many animals including deer, antelope and multiple bird species. (nps.gov)

Mexico1
This species is found in foredunes, active sand, and dune scrub from San Luis Obispo to Baja California, Mexico. (guadalupedunes.com)
Utah1
thorneae from Utah and lumped the various species recognized by Moore and Frankton within a highly polymorphic var. (swbiodiversity.org)
Shown2
Cirsium undulatum has been shown to have its seed production reduced by an exotic weevil Larinus planus which was released to control Canada thistle. (wikipedia.org)
H.nebulella has a more prominent dark costal shadow especially in the distal half of the forewing than is shown by any of the other species, but this is a relative rather than absolute distinction. (weebly.com)
Found1
It has also been found outside of its native range as an introduced species. (wikipedia.org)

I've shared that species on here before so feel free to use the "search this blog" tool on the right to check it out. (blogspot.com)

The Idaho Fish and Wildlife Information System tracks species that are identified as having special conservation status in the following lists. (idaho.gov)
The GRP is home to over 25 wildlife species considered special status by the United States Fish and Wildlife Services (USFWS) and the California Department of Fish and Wildlife (CDFW). (guadalupedunes.com)
