(2) Potentilla argentea---Silvery cinquefoil (3) Thalictrum venulosum---Early meadowrue (4) Very hard to tell without flowers, probably something from Boraginaceae (borago family) of Compositae (aster family) (5) Again, it is hard to say, but looks similar to Solidago sp.---some species of goldenrod |

cin 1 cin 2 cin 3 cin 4 1. I am pretty sure that cin1-4 is Norwegian cinquefoil. Is it really Norwegian cinquefoil? bid 1 bid 2 2. For bid1-2, I'm pretty sure the larger one is Bidens vulgata, which I found last year at North Lemmon Lake, but what about the smaller ones? Are they all Bidens vulgata? lichen 3. This is a lichen, right? I've often seen these in and near salt flats. thistle 4. "thistle." The thistle is Cirsium undulatum, right? ragweed ragweed 2 5. "ragweed, ragweed 2" This is Ambrosia artemisiifolia, right? The stems don't seem as hairy as sometimes I've seen, or as in some pictures I've seen. |

Here are the groupings: 1. First two photos: Bidens 2. Third photo: Onagraceae, but smaller than normal, on butte 3. Fourth through sixth photos: unknown woody shrub 4. Seventh and Eighth--purple aster flower, short, at base of blowout 5. Ninth, leaves like false Polygonatum, no flowers 6. next five pictures-thistle 7. Next picture, Tanacetum, but no flowers 8. Next three pictures, small plant with small green fruits 9. Next three pictures, Eriogonum species 10. Next two, Rumex 11. Last three, that mystery Penstemon or Salvia from earlier |

My determination is Bidens vulgata, Norwegian cinquefoil, lichen, Ambrosia artemisiifolia, Cirsium undulatum. Perhaps I am not correct and I am asking you to check. Thanks. |

A. I have been seeing what I think is Heterotheca villosa in two forms: More commonly, with ~twenty, shorter, more rounded petals Less commonly, with ~12 larger, pointed petals Are these two varieties? B. My daughter picked this. Is it Pulsatilla patens? thank you for your recent determinations. these are the ones from Dogtown WMA: 1. Bidens vulgata? 2. Potentilla norvegica? 3. lichen? 4. Ambrosia artemisiifolia? Сообщение было отредактировано Adams - 02.09.2016 02:17 |

Probably, but again, the quality of photo does not allow to be 100% sure. > 3. lichen? Yes. > 4. Ambrosia artemisiifolia? Yes, most likely. But there is also perennial Ambrosia psilostachya. |

Hoping you can help me with this. I think is is a Sporobolus, but it has broader leaves, is tall, maybe 2 ft, and has a thicker head than photos with Sporobolus tends to be. On the other hand, it has a sheath for the flowerhead and splkelets of the correct shape. Notes: Grass, NW facing slope. Roadside near buffaloberry. Mat forming with Missouri goldenrod.

It appears awnless like this one: 8 mm long blade 5 mm glume 4.5 mm lemma 10 cm inforesence Phalaris arundinacea vs. Holcus lantus 1. Leaves are more narrow than one might expect for P. arundinacea, but just the right size for H. lantus 2. Sheaths have plenty of membrane (Phalaris is "air-chambered"), but are not cross-septate. 3. Stripy pajamas--(Wikipedia 4. Leaves have a grayish sheen to them that could be velvet, but I saw relately few long hairs. It is not as hairy as I am inclined to say it is Holcus lantus due to the stripy pajamas. But then I should check to see which species of Holcus. There is no key for Holcus in Flora of the Great Plains. So I will use this key: This key: H. lantus vs. H. mollis vs. 1. Too erect to be H. mollis 2. lemma too large to be H. mollis, 4.5 mm is even more than H. lanatus is supposed to be. 3. Nodes are beardless (https://en.wikipedia.org/wiki/Holcus_lanatus) 4. "It has been known to hybridize with H. mollis, producing a male sterile hybrid with 2n = 21 chromosomes." Wikipedia---this would be impossible to prove. Mine is too immature to show any pistils. Still, this would be improbable because there is no evidence of H. mollis anywhere nearby. USDA PLANTS shows H. mollis absent from North Dakota. Closest is Idaho. So then I have H. lantus, not H. mollis Yet I would like your advice about which characters would be good to distinguish between Phalaris and Holcus. I am still uncertain. Perhaps Phalaris can have pink veins, too? Unfortunately, my infloresence is somewhat immature. I see no disarticulation, no stigmas, and no filaments. |

Sandy, mossy soil. SE facing slope. With blue grama, other grasses and sedges and Alpine bladderpod, textile onion, milkweed. Only plant I see, about 20 stems, all long and spreading. Сообщение было отредактировано Adams - 20.10.2018 06:24 |

Gentle grassy east facing slope 2 groups of stems, 6 in this one, 7 in the other. With alfalfa, morning glory, Russian thistle, Conzya, crested wheatgrass, Missouri goldenrod, and mustard. Grassy with dry soil. I also found the same species, but not flowering. on a grassy SW facing slope with Asperagus and silverleaf scurfpea. Both sites were abandoned cemeteries where they were mowed once a year or so. I have not seen it anywhere else but these two cemeteries. So it is possibly non-native and introduced.

12 ray florets, disk florets yellow, herbage hispid except for the lowest part of the stem Northeast facing slope, south bank of Cedar Creek, ~6 feet from water's edge with cocklebur, goldenrod, switchgrass, buckbrush, wild licorice, white sagebrush, hedge false bindweed, and rough bugleweed. Gregarious. August 23rd. This would possibly be H. Helianthus nuttallii subspecies rydbergii: leaves "mostly opposite, lancolate to obvate". I haven't seen any subspecies rydbergii herbarium images online yet, though, only subspecies nuttallii. efloras: Leaves: petioles (1–)2–5 cm, blades 10–32 × (1.2–)4–9 cm, margins coarsely serrate 42 Helianthus grosseserratus Leaves: petioles 0.5–1.5 cm, blades 4–20 × 0.8–4 cm, margins entire or shallowly serrate 45 Helianthus nuttallii (in part) So what do you say: H. grosseserratus or H. nuttallii? |

(plantago @ 10.11.2018 06:20) The leaves look like pinnate not triple. Is it OK? Or I'm wrong?

Notes at collection (8/26/2016): Steep, grassy and shrubby northeast facing slope, South bank of Cedar River, about 20 feet above water level. Only 2 seen. The plant I collected had different shaped leaves than scanned herbarium specimens available online (such as Yet It seems to be Ceanothus because of the leaf venation. The "tendrils" in the picture could be roots along the stem. Flora of Great Plains does not mention these roots, but the ability of this plant to root by stem is mentioned here: This one appears different than Rhamnus alnifolia especially due to leaf shape, but possibly also berry position and "tendrils." If they really are tendrils my determination must be wrong. However, it fits best as R. alnifolia because the leaves are alternate and the flowers/fruits are in the leaf axials as auxiliary umbels. Yet these umbels are not sessile as they are supposed to be (p. 555 of Flora of Great Plains) and this is part of why it appears to be a Ceanothus. Changing the topic, the Silene above was S. menziesii. This species is not currently listed for North Dakota according to the USDA PLANTS database. However, it is listed for Manitoba, Kansas, and Montana. So it is conceivably a ND species simply by geography. For determination, I used the efloras key, but removed consideration all plants that were not USDA PLANTS listed for Montanta and the Dakotas. All other plant species keyed out somehow, were obviously unfit due to habit, or were removed under careful consideration on the characters of the calyx, stem, leaves, and petals. The next best fits to this one were Silene vulgaris and S. latifolia, but this cannot be S. vulgaris because the leaves are not rounded at the base. Additionally, leaf veination of scanned herbarium specimens differ from this one. It cannot be S. latifolia because the leaf venation is different. Also, S. latifolia has long pedicels for the flowers and does not appear to spread by underground roots. In contrast S. menziesii spreads by underground roots (see this scan: Looking at the scans, it seems that not all S. menziesii specimens show this venation. However, it seems from the efloras species description that S. menziesii has more morphological variation than the other Silene that I considered. The total list of Silene species which I considered: SIAN2 Silene antirrhina L. sleepy silene, SICS Silene csereii Baumg. Balkan catchfly, SIDI2 Silene dichotoma Ehrh. forked catchfly, SIDR Silene drummondii Hook. Drummond's campion, SILA21 Silene latifolia Poir. bladder campion, SINI Silene nivea (Nutt.) Muhl. ex Otth evening campion, SINO Silene noctiflora L. nightflowering silene, SIVU Silene vulgaris (Moench) Garcke maidenstears. This species was found in two cemeteries in neighboring townships. This would have been an easy-to-propagate Silene given that it was a perennial which spread from adventitious roots. So although it is a wild plant, it is probably that these two were cultivated originally, between 80-100 years or so ago and then re-naturalized.

I don't think this one can be Buglossoides arvensis (L.) I.M. Johnst. (also called Lithospermum). It has the leaf veination of Hackelia, but the fruiting pattern and long hairs of Asperugo procumbens. Yet ever photo I find of Asperugo procumbens, venation is very, very light save for one single mid-vein. I have been using this as a short list of comparison Notes: July 7th, 2018 Under buffaloberry bush. Heavily shaded along with stinging nettle. Steep N facing slope. |

I had excluded Cymopterus from consideration due to a misinterpretation of the key in Flora of the Great Plains. I have another question: East facing slope. Grassy with sedges, Artemisia, mustard, penstemon (light blue), 35k-10, rocket mustard, textile onion, 75% ground cover. Near old manure. ~14 cm high, leaves up to ~3 cm If you could suggest possible genera--this would help me. I think it is Compositae. Collected May 30th.
