Lupin bread
What is lupin bread and is it made from lupin flowers? 46.69.252.235 (talk) 10:29, 15 May 2022 (UTC) Martin of Sheffield (talk) 10:34, 15 May 2022 (UTC)
 * See Lupin bean. "Lupin beans can be ground into a flour, and this is widely used in parts of Europe and in Australia as an additive to wheat flour, enhancing the flavour and lending a rich, creamy colour to the resulting foods"
 * I read the article, thanks. But do the beans come from the flowers? 46.69.252.235 (talk) 10:39, 15 May 2022 (UTC)
 * After the flower is fertilized, a pod grows with the beans inside. Picture of a pod with beans here: https://www.abc.net.au/news/2017-08-28/lupin-pod/8849902?nw=0 Graeme Bartlett (talk) 11:34, 15 May 2022 (UTC)
 * As an aside, the OP may wish to learn more about legumes. They broadly fit into the Fabaceae family of plants and include a really large variety of different forms, including trees, bushes, and small shrubs.  What makes legumes, well, legumes is that they produce these seed pods; these can be small ones like beans and peas and lentils or really large ones like Acacias or Tamarind.  Everything we think of as a "bean" is usually from the Fabaceae family, and they have a shared physiology that makes them similar. -- Jayron 32 16:50, 17 May 2022 (UTC)

what if any is the difference between orphan diseases and rare diseases
I am wondering after reading the article on rare diseases are rare diseases and orphan diseases the same thing? OhioGirl42986 (talk) 19:35, 15 May 2022 (UTC)OhioGirl42986


 * I'm not sure what more detail we can add that isn't already provided in the article. In the lead it says, "A rare disease is any disease that affects a small percentage of the population. In some parts of the world, an orphan disease is a rare disease whose rarity means there is a lack of a market large enough to gain support and resources for discovering treatments for it..." (emphases in original). There's also a section devoted to definitions which provides some context. 70.24.163.91 (talk) 22:09, 15 May 2022 (UTC)

Plant identification
Can anyone identify this plant with the blue flowers? Growing on downland in the south of England. ITookSomePhotos (talk) 19:55, 15 May 2022 (UTC)
 * I thought at first it was Spring gentian, but the leaves are wrong. Will keep looking. {The poster formerly known as 87.81.230.195} 90.208.88.97 (talk) 22:05, 15 May 2022 (UTC)
 * Perhaps Lamium purpureum? If i recall it's the right time of year Zindor (talk) 22:12, 15 May 2022 (UTC)
 * Actually looking again it's not lol. Zindor (talk) 22:15, 15 May 2022 (UTC)
 * Perhaps Glechoma hederacea. It's a member of Lamiaceae or the mint family and so will have square stems and a mint aroma when its leaves are crushed. Modocc (talk) 00:39, 16 May 2022 (UTC)
 * Thank you very much. I will have to check back later if possible on those points, but from photographs it does look very likely. ITookSomePhotos (talk) 08:16, 16 May 2022 (UTC)
 * You could also consider Ajuga. Bazza (talk) 08:50, 16 May 2022 (UTC)
 * My copy of Wild Flowers at a Glance says that ground ivy (glechoma hederacea) appears in spring and early summer, is "very common in Britain" and can be found in "waste places, hedge-banks and copse edges". Some is of it flowering now in my lawn - maybe time to get the mower out. Alansplodge (talk) 10:54, 16 May 2022 (UTC)
 * Glechoma hederacea is correct.  Eve rgr een Fir  (talk) 19:30, 16 May 2022 (UTC)
