88 Standley : Some Echinocerei of New Mexico 



ing, about as long as the laterals and of the same color : flowers 



numerous, usually produced all over the plant, a peculiarity in which 

 the plant differs from the other species here discussed ; flowers about 

 50 mm. long, 25-30 mm. in diameter, narrow, not spreading as in 

 the other species ; petals firm in texture, almost or quite acute at 

 the apex, upper part of the petals bright-scarlet, lower part green- 

 ish-yellow, petals about 6 mm. wide ; tube of flower covered with 

 abundant, spreading, rather long, bristle-like spines ; stamens about 

 one half as long as the style, anthers rose-colored, filaments white 

 or tinged with rose ; stigmas about 7 : fruit not seen. 



The variegated appearance of the spines, the distribution of 

 the flowers on the plant, the small, contracted flowers, make this 

 species distinguishable. The type is Standley 383 in the herba- 

 rium of the Missouri Botanical Garden, in the Gray Herbarium, 

 and in the National Herbarium, all the specimens being taken from 

 the same plant. A number of the plants are still growing in the 

 College cactus garden ; they were brought from the mesa west of 

 the Organ Mountains, Dona Ana Co., New Mexico.
