Lilium parryi
Lilium parryi, common name lemon lily, is a rare species of lily. "Lilium parryi" is native to the southwestern United States and northwestern Mexico where it grows in moist areas in mountain habitats. In California it is currently known from the San Bernardino and San Gabriel Mountains and a few remaining spots near Palomar Mountain to the south. It is the only true lily native to Arizona, where a few populations can be found in the Huachuca, Chiricahua, and Santa Rita Mountains. In Mexico, it has been found in mountains in the states of Sonora and Baja California . "Lilium parryi" is a perennial herb growing erect to about 2 meters in height from a scaly, elongated bulb up to long. The leaves are generally linear in shape, up to long, and usually arranged in whorls around the stem. The inflorescence is a raceme bearing up to 31 large, showy, bright lemon yellow flowers. The trumpet-shaped, fragrant flowers have six curling tepals up to long, sometimes with a few reddish spots. There are six stamens tipped with large anthers up to long. The pistil may be long. The flowers are pollinated by hawkmoths, especially "Hyles lineata" and "Sphinx  perelegans". Threats to this species include grazing, recreation, natural flooding and human alterations in water regimes, and horticultural collecting of the bulbs and flowers. "Lilium parryi" was named for Charles Christopher Parry (28 August 1823 – 20 February 1890), a British-American botanist and mountaineer. Idyllwild, California, hosts the Lemon Lily Festival, which celebrates this species.
