Lycium andersonii

 Lycium andersonii (Anderson boxthorn) ( )

Solanaceae


  • It is the most widespread and commonly encountered species of boxthorn, which occurs widely across our desert areas on gravelly or rocky slopes flats and slopes,  with habitats ranging from creosote bush scrub up into pinyon-juniper woodlands. It is also found in scattered locations in the arid areas of the southern San Joaquin Valley and desert slopes in the Transverse Ranges and extends eastward in the Great Basin. Anderson boxthorn is commonly 3-5 feet in height but can reach as tall as 8 feet.. It has small fleshy leaves usually less than 1/2 inch in length that are hairless, and thus generally pale greenish in color.

  • It is a thorny shrub with relatively elongated, narrow leaves and flowers. The flowers are considerably smaller than those of L. brevipes and L. fremontii. The corolla is lavender and the small fruit is bright orange. Food: the fruit was cooked in water. Eating the fruit was said to produce no adverse effects. It was not a major food resource.

Lupinus arizonicus

  Lupinus arizonicus (Arizona lupine) ( ) Fabaceae Arizona lupine is one of the most common and conspicuous desert lupines when it blooms in sandy washes and open creosote bush scrub below 3,000 feet in the Mojave and Sonoran deserts. Its is particularly abundant in spring along roadsides. Although an annual, Arizona lupine is a robust plant that is typically 1-2 feet in height. Its stems and the underside of its green leaflets have long, spreading hairs. The purple flowers have a yellowish spot on each of the banners, which are the two petals that spread horizontally.

Asteraceae

Asteraceae The most diverse and ecologically significant family of woody and semi-woody shrubs in creosote bush scrub is the sunflower family. Globally Asteraceae is second only to the Orchidaceae in number of species. Memers of the Asteraceae family are challenging to identify until one becomes familiar with flower structures. The essential feature defining the Asteraceae is the presence of composite flower heads that typically include numerous tiny flowers joined in what, at first, resembles a single large flower-as seen in a familiar sunflower. The typical composite flower head is composed of two types of flowers, although either one of these types may be absent in some genera. The outer whorl of flowers in a typical composite head has three petals fused to form what appears to be a single large petal, while the other two petals are absent. These fused petals of the ray flowers, or ligules, are the attractive structures for pollinators. Ray flowers are almost always female. The inne...

Agavoideae

 Agavoideae Joshua trees, along with other of Yucca , have a remarkable pollination system that involves a mutualistic relationship with species of yucca moths ( Tegeticula spp. ). The female yucca moth gathers pollen from yucca flowers using her specially adapted mouthparts. Once she has collected enough sticky pollen, she forms it into a ball which she presses against the stigma of every yucca flower she visits, pollinating these flowers. At the same time, she injects her eggs into the female tissue of the yucca flower. As the fruits of the yucca mature, they produce numerous large seeds and, at the same time, host the developing larvae of the yucca moth. The food sources of these developing larvae are the seeds of the yucca, but the larvae consume only a portion of the seeds. When the larvae are mature, they excavate an exit hole from the fruit, drop to the ground, form a cocoon, and emerge the following year. The undamaged seeds mature and are shed- and under appropriate condit...
