Astragalus onobrychis L.DE: Esparsetten Tragant, Esparsetten StragelSlo.: dolgojadrni grahovecDat.: June 27. 2010Lat.: 46.33443 Long.: 13.63594Code: Bot_432/2010_IMG1159Habitat: Larger openings in riparian wood, Picea abies and Salix eleagnos dominant; alluvial, shallow, stony and sandy, calcareous ground; flat terrains; full sun, locally dry place; exposed to direct rain; elevation 425-430 m (1.390-1.410 feet); average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, alpine phytogeographical region. Substratum: soil among stones and sand.Place: Lower Trenta valley, left bank of river Soa, near confluence with Lepenica stream, east of 'Za otoki' place, East Julian Alps, Posoje, Slovenia EC.Comment: Astragalus onobrychis is west Asian - east European plant growing in many parts of the Alps, Apennines, Carpathians, Dinaric and south Balkan Peninsula mountains. The warmth loving plant hadn't been known in the alpine and prealpine phytogeographical region of Slovenia until recently. In 2008 it was discovered on an isolated, locally sunny and warm place in Trenta valley at the mouth of Lepena side valley. It is now showing its beautiful violet flowers year after year on more or less the same place. For now this is its only known location in Julian Alps and among the most northern in Slovenia.Ref.:(1) Personal communication with Dr. Igor Dakskobler, Natural History Institute Jovan Hadi, SAZU.(2) M.A. Fischer, W.

Astragalus sabulosus var. vehiculus. A Utah endemic and very rare species known from a single element occurrence. First time I had seen it this late in the year. And the first time I had since it in the field in 26 years.Taken on September 26, 2010, Grand Co., Utah

Astragalus cibarius E. Sheld. Among our earlier blooming species.Phylogenetically this species is thought to be closest to A. ensiformis (which does not occur in this part of the state). The leaves do not usually exceed the height of the flowers in this species. The inflorescence arises from the upper portion of the leafy stem and does not arise separately.March 28, 2009, Salt Lake County foothills, open space, steep slope, near base of Big Cottonwood Canyon.

A collage of pictures taken on the same day and in the same area with an old camera starting with a juvenile plant (upper left), a plant in flower, a closeup of the flowers using my best available "macro" lens at the time, and a plant with fruits. Astragalus holmgreniorum was named by the late legume expert Rupert Barneby in 1980 for Drs. Noel and Pat Holmgren who were with him when the type was initially collected in late May of 1979. Barneby's common name for this species confusingly was "Paradox milkvetch" because he meant it as a previously christened name for the two PhD's that where with him (i.e. a "pair of docs") and not because it has any significance with respect to the location of the plants nor the formation on which it grows. A common name of "Holmgren's milkvetch" is sometimes used but since it was named in honor two people, if a possessive form of the name is used it should instead be "Holmgrens' milkvetch." Simplifying this to "Holmgren milkvetch" seems in this case best. There are no rules for the common names of plants, so choose your own!Plants belonging to same species were collected by Marcus Jones (late 19th century) and by Melvin Oden in the early 1940's but not recognized as a new species until much later.This milkvetch is unique in having an acaulescent stem so particularly when in fruit, it appears to be sprawling and laying flat on the ground. The white-tipped keels (visible at lower left above) are often not described as characters of the flower. It co-occurs with a smaller statured milkvetch, Astragalus nuttallianusThis is a Virgin-Mohave endemic that is highly restricted to localities south of St. George and just barely into Arizona. All of its locations are under a variety of threats, primarily habitat loss but also invasive species (Red brome, African mustard and Cheatgrass primarily) and recreational impacts. It typically occurs in gravelly draws.It was listed as endangered on 9/28/2001 following a petition for its listing by the Center for Biological Diversity (CBD) (although it was also a candidate species at the time of the 1999 petition and reportedly the FWS was already working on a listing proposal at the time of the petition). Its ultimate listing included a provision for the designation of critical habitat as prescribed under the Act, however, no habitat was designated at the time of listing forcing the need for a lawsuit involving CBD and the Utah Native Plant Society which was successful. Designation of critical habitat was then finally made as a result of that lawsuit on 12/27/2006 and a recovery plan finalized several months prior.The "best" occurrence of this species is about to have a city built over it and involves habitat that SITLA allowed (and paid) to be surveyed but refused to protect. This is typical SITLA behavior; the state of Utah only pays attention to federally listed species and typically will take no action with respect to plant species (unless forced) otherwise creating the need for yet more suits.May 1, 2004, Washington County, Utah, elev. approx. 2,725 ft.

Astragalus ensiformis M.E.JonesMarch 27, 2004, Zion National Park, southwestern section of park, Washington Co., Utah. Known only from Washington Co., Utah, adjoining Mohave Co., Arizona and southeastern Nevada. Barneby recognized two varieties, var. ensiformis which diffuse or humifuse stems with a more limited distribution that did not include Nevada, and var. gracilior with assurgent stems and narrower and less pulpy pods. It was too early for any pod development at this time. Based on distribution, this would fall slightly closer to var gracilior than var. ensiformis if one were to follow Barneby, however, it isn't clear which stem type this would fall in as it seems to share characteristics of both, but perhaps mainly assurgent. . Welsh does not recognize varieties. Without knowing more, I will follow Welsh here.Phylogenetically this species is thought to be closest to A. cibarius.
