California Trees and Flowers. 145 



L. effusa Gray. An equally beautiful species of the mountains 

 of Lower California, low in habit with light rose purple flowers. 

 Like Phlox and Gilia, Loeselia is a genus of lovely flowers, well 

 worthy of cultivation. 



LUPINUS. 



Showy annuals or perennials, a few shrubby, bearing conspicu- 

 ous flowers in terminal racemes. The great majority are indigenous 

 to West America. Many have long been cultivated and grown 

 popular. The California species best known in cultivation are the 

 following : 



L. affinis Agard. A foot or two high, often growing very rank, 

 producing large spikes of brilliant blue flowers. 



L. DENSiFiiORUS Benth. Less than a foot high, with white flow- 

 ers arranged in umbel like clusters on the terminal spike. Some- 

 times light sulphur yellow. 



L. micranthus Dougl. Low in habit, with racemes of small 

 light blue and white flowers. The cultivated form is considered 

 quite pretty. 



L. nanus Dougl. A slender plant, with bluish, purple or white 

 flowers. 



L. nanus albus. The white flowered form. 



L. arboreus Sims. The Tree Lupin is a shrub four to ten feet 

 high, with lilac colored flowers. 



L. arboreus luteus. With sulphur yellow flowers, perhaps the 

 typical form. A very ornamental shrub. 



L. elegans. What its name signifies. 



L. grandiflorus. A perennial form, with blue, white or purple 

 flowers. 



L. polyphyllus Lindl. Perennial, similar to L. grandiflorus if 

 the two are not identical or forms of the same species. 



L. polyphyllus albiflorus. The white variety. 



MAMILLARIA. 



Very general favorites among the lovers of the odd or the beau- 

 tiful are these unique little plants, most exquisite in form and finish. 

 The scarlet edible berries, which cluster among the spines of our 

 California cacti of this genus add also to the beauty of these plants, 

 though the blossoms are often inconspicuous. 



M. deserti Engelm. A little gem, from the Mojave Desert, of 

 which we have as yet seen but a single plant. One of the choicest of 

 the genus and we hope to rediscover the beauty soon. 



M. Goodridgii Scheer. Sometimes called the Strawberry cactus, 

 from the delicious flavor of its clubshaped fruit, but also called the 

 Fish-hook cactus from the hooked central spines produced from the 

 mamillae. The spines are sometimes of an ivory whiteness, but 

 oftener of a rich brown color. 



M. phellosperma Engelm. A handsome plant, worthy of a 

 place in any lady's parlor.
