﻿-174 Small : Studies in the Botany 



ridged, strict, rather slender, simple at least below the inflores- 

 cence : leaves numerous ; blades linear, very narrowly so except 

 those of lower leaves, 5-10 cm. long or shorter above, erect or 

 strongly ascending, sparingly punctate, lower ones narrowed into 

 sparingly ciliate petioles : heads numerous, slender, short-pe- 

 duncled or the peduncles sometimes elongated and minutely 

 bracted : involucres cylindric, 5-7 mm. high : bracts glabrous or 

 nearly so, erect, appressed, obtuse, outer ovate, inner oblong, much 

 longer than the outer, pappus-bristles coarsely barbellulate : achenes 

 cuneate, about 2.5 mm. long, densely pubescent. 



In sandy soil, Cumberland Mountains, Tennessee. Summer. 



The segregate just described has heretofore been associated 

 with Lacinaria graminifolia. However, its foliage is glabrous ex- 

 cept for an occasional cilium on the petioles of the lower leaves or 

 the edge of the involucral bracts. The cylindric heads are only 

 about one-half as large as those of Lacinaria graminifolia and 

 contain few flowers. 



The original specimens were collected by Dr. Gattinger at 

 Tullahoma, on the Cumberland Mountains, Tennessee, in August, 

 1867"; September, 1877; August, 1878, and the fourteenth day 

 of the same month, 1886. I am indebted to Prof. S. M. Bain, of 

 the University of Tennessee, for the loan of the above cited speci- 

 mens from the University Herbarium. 



' Soli dago delicatula. 



Perennial, smooth and glabrous, deep green. Stems erect, 

 5-IO dm. tall, ridged, sparingly or widely branched above, strict: 

 leaves numerous; blades thinnish, somewhat parchment-like at 

 maturity, linear-elliptic to linear-lanceolate or nearly linear, 2-8 

 cm. long, acuminate, sharply serrate, beyond the gradually nar- 

 rowed base, sessile or with short winged petioles : panicle narrow 

 or, when well developed, with widely spreading and recurved 

 branches : heads numerous, 3.5-5 mm. high, short -peduncled, con- 

 tiguous : involucres narrow : bracts narrowly lanceolate to narrowly 

 linear, acute, very variable in length : flowers 3-6 : rays yellow, 

 often 2-3, linear-oblong, 1.5-2.5 mm. long: achenes minutely 

 pubescent. 



On prairies, northern Texas.
