Q

                   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 simply
                  that sometimes there is no single correct pronunciation. In other instances, the way I record it is just
                  that which sounds right to my ear.

• quadrangular'is: four-angled (ref. Cicendia quadrangularis)
• quadrangula'ta: same as quadrangularis (ref. Eleocharis quadrangulata)
• quadricosta'ta: four-ribbed (ref. Cusickiella quadricostata)
• quadrifo'lia: four-leaved or -needled (ref. Pinus quadrifolia)

• quadriradia'ta: with four ray florets or with four radiating structures (ref. Galinsoga quadriradiata)

• quadrivul'nera: the root vulner comes from Latin vulnerator, one who wounds or mutilates, in turn from vulnus, a wound, or vulnero, to injure, damage, so this means something like "with four wounds or injuries." 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 (ref. Clarkia purpurea ssp. quadrivulnera)
• 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)." (ref. Camassia quamash)

He was a forest ecologist for the U.S. Forest Service and a plant pathologist and consultant for the Pacific Southwest Forest and Range Experimental Station. 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. He wrote articles on gooseberries, blister rust, fungicides and germination of Ceanothus seeds (ref. Phacelia quickii)
