Horned Toad Cactus (Mammillaria Mainæ)
Southern Arizona and Northern Sonora
This rare little cactus was found in Arizona for the first time in 1931. Two or three inches high and nearly as broad, he seems to be sitting up in front of us like a horned toad, looking us over, his head flattened out in a slightly grotesque posture, pale green tubercles in thirteen or more spiral rows covering his flabby body, from which spring the dozen or so white and yellow radial thorns and the hooked central spines, also forming into a regular spiral twist. The brown and red striped flowers, an inch or so long, are not the lovely showy beauties of his brother baby cacti. Perhaps his easy life in grassy lands away from hottest sun and arid habitat needs not the compensation of the beauty afforded his less fortunate brothers and sisters. Does Nature make up for the hot aridity of the desert and the barren wastes of sand and more sand, by brilliance of flower and wealth of fantastic design? It would seem so, for nowhere else in the world are to be found the weird, grotesque shapes, the flaming splendor and fragrance of blossom, the kaleidoscopic changes of color and pattern which are created far out on the dry expanses, under the burning sun and during seasons of inconceivable drought.
Snowball Cactus (Mammillaria Oliviæ)
Southern Arizona
Next we see Oliviæ, the rose-tinted Snowball Pincushion, clad in a white coat of twenty-five or thirty radiating spines crowded together in a comb-like arrangement pressed closely against her body and looking like a snowball lying on the hot sand before us; the delicate rose-colored blossoms edged with a narrow band of white form a beautifully designed pincushion; even the stamens are deep rose, the styles light pink with olive-green stigmas, the fruit bright scarlet, and the seeds black. Is it any wonder that this riot of color, a rare desert form of the Mammillaria Grahamii, is also called the Sunset Cactus?
Green Flowered Pincushion (Mammillaria viridiflora)
Southeastern Arizona (Globe)
The Green Flowered Pincushion would make a lovely addition to my lady’s bower in a window rock garden. Not a desert species, it inhabits the higher mountain levels, often in oak woodlands; it is a rare beauty, difficult to find. Two or three inches in length and diameter, its stem and tiny bell-like flowers are both green, the radial spines loosely interlocking over the body of the plant, slender flexible thorns, white or reddish brown with sharp hooked tips. It is a near cousin to Mammillaria Wilcoxii.
