In the following names, the stressed vowel is the one preceding the stress mark. It is not always easy to ascertain where such stress should be placed, especially in the case of epithets derived from personal names. I have tried to follow the principle of maintaining the stress of the original name as outlined in the Jepson Manual, and have abandoned it only when it was just too awkward. In the case of some names, I have listed them twice, reflecting either some disagreement or conflict in the rules of pronunciation, some uncertainty on my part as to the correct pronunciation, or that simply sometimes there is no single correct pronunciation. In other instances, the way I record it is just that which sounds right to my ear. Where no credit is given for photos, they are in public domain mostly from Wikipedia.

The Clarkia which bears this name has 4 petals, each of which has a darker pinkish-purple spot on it, as if it were wounded and bleeding.
  • qua'mash: according to Wikipedia, "The name Quamash is a Native American term for the plant's bulb, which was gathered and used as a food source by tribes in the Pacific Northwest. The bulbs were harvested and pit-roasted or boiled by women of the Nez Perce, Cree, and Blackfoot tribes. It also provided a valuable food source for the members of the Lewis and Clark expedition (1804-1806)."
  • quartinia'num: named for Léon Richard Quartin-Dillon (1811/4-1840), physician, botanist and museum naturalist. He was born Ricardo Leão Quartin in Lisbon the son of a father from Gibraltar and a Portuguese mother. His second surname may have come from the Irish-French husband of one of his aunts. He embarked on a voyage from 1838 to 1843 led by Théophile Lefebre to study the natural history, geography, anthropology, linguistics, archeology and customs of Abyssinia. Material that he and others on the expedition collected formed the basis for Achille Richard's two-volume flora of Ethiopia entitled Tentamen Florae Abyssinicae. Quartin-Dillon died in Africa.

  • Quer'cus: the classical Latin name for the oak from Roman times, interestingly no certain derivation for the name, possibly from the Celtic quer, "fine," and cuez, "tree." John Cameron's Gaelic names of plants (Scottish and Irish): collected and arranged in scientific order, with notes on their etymology, their uses, plant superstitions, etc., among the Celts, with copious Gaelic, English, and scientific names (1883) states: "Quercus — Said in botanical works to be from the Celtic, quer, fine. There is no such word in any Celtic dialect, and even [Arnold] Pictet has failed, after expending two pages on it, to explain it." Another source (Gledhill) says that it shares the same linguistic derivation as the Arabic al-qurk and the word cork.

Some of his areas of research included seed germination, dormancy and longevity, ecology of forests and forest species, and chemical control of plants and tree diseases.
