12. Cryptanthe vitrea, sp. nov. 



Annual, with several stems from a tap-root, 1-2 dm. high, very hispid 

 throughout with white bristly hairs which are pustulate at base. Leaves 

 linear, 1-2 cm. long, 2 mm. wide, strongly nerved. Flowers sessile, in 

 numerous short spikes from almost the lowest axils, on slender peduncles. 

 Calyx 3 mm. long, the sepals conniving to form a tube around the nut- 

 lets, the tips free, densely clothed with long stiff bristles, 3 mm. long, 

 and also a fine, white, hispid pubescence. Corolla only about 2 mm. long, 

 with a small limb. Nutlets, only two maturing, ovate, obtuse, almost 2 mm. 

 long and i mm. wide at base, very glossy brown mottled, sharply tuberculate, 

 attached to the gynobase for the entire length, the groove closed except at 

 the forks. 



The species comes nearest to C. muricidata Greene, but 

 the nutlets are broader, the flowers much smaller, and the 

 entire plant so floriferous that in the dried specimen it is 

 almost impossible to distinguish the peduncles. 



Collected by the author on Bubbs Creek trail, July 5, 

 1899. 



\/ 13. Aster durbrowi, sp. nov. 



Stems erect, perennial from creeping root-stocks, disposed to grow in 

 tufts, 1-3 dm. high, sparingly leafy, erect, branching only at the inflores- 

 cence, glabrous and green except for some white woolly hairs which are 

 sparse on the lower part, but which make the upper part almost cinereous. 

 Radical leaves on long winged petioles which are dilated and clasping-at— "" 

 base, lanceolate, the blades about as long as the petiole, together 5-8 cm. 

 long, 5-10 cm. wide, entire or distantly serrate, ciliate on the margin, the 

 hairs becoming longer towards the base of the petiole and decurrent on 

 the stem; cauline leaves similar but sessile by an auriculate or cordate clasp- 

 ing base, the upper ones broadening and becoming shorter and more 

 pointed, the lower ones narrowing towards the insertion. Heads cymose, 

 the branchlets terminated by one to four middle-sized heads, 1-2 cm. across, 

 on short bracteate pedicels; involucre of six rows of imbricated bracts with 

 green, foliaceous tips, not spreading, the inner ones with purplish acuminate 

 tips, the outer linear, mucronate, glabrous except for the ciliate margins, 

 distinctly one-nerved and chartaceous at base; rays pistillate, reddish purple, 

 I cm. long, 1.5 mm. wide, dentate at apex, sparingly ciliate on the lower 

 part; disk flowers purplish; corolla shorter than the pappus, which extends
