5 hispidly margined carpels ; stamens many ; bractlets filiform, 

 as long- as the calyx tube ; central pedicels filiform, kinked in 

 the middle, 1-2 inches long", others short ; flowers erect in very 

 open panicles. Guayanopa Canyon, Sierra Madre Mts., Chi- 

 Imahua, Mex., Tropical Life Zone at 3,600 feet alt., Sept. 24,

Cerastium Diehlii n. sp. 



This is like C. sericeum but perennial; many-stemmed, 

 dichotomously branched above ; leaves linear-acuminate. 

 1-3 inches long-. 2-3 lines wide, viscid and hairy throughout 

 but not densely so; otherwise as in C. nutans; plants about a 

 foot high. Hop Canvon Magdalena Mts., N. M., Aug., 1903,

; shrub 2-6 inches high with herba- 



by 2 petaloid bracts hke the sepals which are nearly 1 line 

 long-; calyx faintly 5-nerved, and .S-cleft nearly to the base into 

 oval-ovate, simply apiculate, hyaline sepals barely 1 line long-, 

 with thick and g-reen midrib vanishing toward the top, sepals 

 inclined to be conduplicate but little spreading in the pistillate 

 Ilowers and surpassing the bracts somewhat; flowers dioecious, 

 the pistillate narrower; stamens 5, about as long as the sepals; 



Scopulophila nitrophiloides n. sp. 



Whole plant smooth, but on drying becomes roughened by 

 the wrinkling of the rather fleshy pulp; stipules conspicuous, 

 l.iciniate, at the base of the stems they are densely aggregated 

 as the scales in ferns are, forming a bulb-like tuft ; stems knot- 

 ted at the joints and branched at every joint, wi'^h appressed 

 Irinches which fork again; leaves flat, thick, acute, widely 

 spreading. 6-9 lines long, gradually reduced above ; all the upper 

 axils florifcrous : staminate flowers inconspicuous, pistillate evi- 

 dent and resembling Galium multiflorum at a distance ; on close 

 inspection the plant so closely resembles Nitrophila that only
