Omphalodes verna (common names creeping navelwort or blue-eyed-Mary) is an herbaceous perennial rhizomatous plant of the genus "Omphalodes" belonging to the family Boraginaceae.
Hericium is a genus of edible mushrooms in the Hericiaceae family.
 Species in this genus are white and fleshy and grow on dead or dying wood; fruiting bodies resemble a mass of fragile icicle-like spines that are suspended from either a branched supporting framework or from a tough, unbranched cushion of tissue.
 This distinctive structure has earned "Hericium" species a variety of common names—monkey's head, lion's mane, and bear's head are examples.
 Taxonomically, this genus was previously placed within the order Aphyllophorales, but recent molecular studies now place it in the Russulales.
Gelsemium is an Asian and North American genus of flowering plants belonging to family Gelsemiaceae.
 The genus contains three species of shrubs to straggling or twining climbers.
 Two species are native to North America, and one to China and Southeast Asia.
Mimophytum is a genus of flowering plants in the family Boraginaceae.
 The species occur in Northeastern Mexico and adjacent areas of Texas, United States.
 They are similar to the closely related genus "Omphalodes" but a distinct group.
Omphalodes (navelwort) is a genus of flowering plants in the family Boraginaceae.
 Widely distributed in the temperate Northern Hemisphere.
 In spring they produce blue or white flowers similar to forget-me-nots.
Deckenia is a genus of freshwater crabs from East Africa, in the family Potamonautidae, or sometimes in a family of its own, Deckeniidae.
 The genus was named by Hilgendorf after Karl Klaus von der Decken who collected the first examples during his expeditions to Africa.
 Both species live in swamps from Eyl in Somalia to Dar es Salaam, Tanzania, both in coastal areas and further inland.
 A third species, "Deckenia alluaudi", lives in the Seychelles, and has been transferred to a separate genus, "Seychellum".
Benguetia is a genus of fungi in the Helotiales order.
 The relationship of this taxon to other taxa within the order is unknown ("incertae sedis"), and it has not yet been placed with certainty into any family.
 This is a monotypic genus, containing the single species Benguetia omphalodes.
A list of species in the genus Omphalodes'.
Pteleocarpa is a genus of flowering plants.
 The only member of the genus is the western Malesian tree Pteleocarpa lamponga.
 It has had a varied systematic history and has been placed in the families Icacinaceae, Cardiopteridaceae, Boraginaceae, and others.
 It has long been regarded as enigmatic.
 For example, its winged fruit is quite odd within the family Boraginaceae, where it was usually placed in the 2000s.
 The family name Pteleocarpaceae had been used, but was not validly published until 2011, when the required description was published in Kew Bulletin.
 A morphological study of "Pteleocarpa" was published in 2014.
 Also in 2014, a molecular phylogenetic study of the lamiids (a.k.a. Garryidae) sampled "Pteleocarpa" and resolved it as sister to Gelsemiaceae.
 Both genera of Gelsemiaceae ("Gelsemium" and "Mostuea") were sampled and this result had maximum statistical support in three different methods of cladistic analysis.
 The authors of that study recommended that "Pteleocarpa" be included in Gelsemiaceae.
 This was formally done in 2014 by altering the description of the family to accommodate it.
 In the APG IV system published in 2016, "Pteleocarpa" is included in Gelsemiaceae.
Gelsemine (CHNO) is an indole alkaloid isolated from flowering plants of the genus "Gelsemium", a plant native to the subtropical and tropical Americas, and southeast Asia, and is a highly toxic compound that acts as a paralytic, exposure to which can result in death.
 It has generally potent activity as an agonist of the mammalian glycine receptor, the activation of which leads to an inhibitory postsynaptic potential in neurons following chloride ion influx, and systemically, to muscle relaxation of varying intensity and deleterious effect.
 Despite its danger and toxicity, recent pharmacological research has suggested that the biological activities of this compound may offer opportunities for developing treatments related to xenobiotic- or diet-induced oxidative stress, and of anxiety and other conditions, with ongoing research including attempts to identify safer derivatives and analogs to make use of gelsemine's beneficial effects.

Question: The genus Omphalodes and the genus Gelsemium are both examples of what?
Answer: flowering plants
