Gerardia viridis. 



Annual, slightly scabrous, drying green. Stems erect, 2-6 

 dm. tall, branching, sharply angled : leaves opposite or slightly 

 scattered ; blades narrowly linear, 1-2 cm. long, acute, revolute, 

 scabrous along the edges, sessile or nearly so : pedicels ascending, 

 8-15 mm. long, as long as the leaves or shorter, slender: calices 

 4-5 mm. high ; tubes turbinate to turbinate-campanulate ; teeth 

 acute, about one third as long as the tubes : corollas yellowish- 

 pink, less than 1 cm. long ; segments ciliate, truncate or barely 



emarginate. 



In sandy soil, Arkansas to Louisiana. Summer and fall. 



At least two species in addition to the type are passing under 

 the name Gerardia Skinncriana. The one I have just separated 

 in the above description can be easily recognized by the coarser 

 habit, the larger and broader leaves and the long calyx-teeth ; 

 these form a strong contrast with the minute teeth of the calyx of 

 Gerardia Skinneriana. Mr. Heller has collected excellent speci- 

 mens of the species about Texarkana, Arkansas, during the past 

 season, no. 4240. Dr. Hale found it many years a little further 

 south at Alexandria, Louisiana. 



SOLIDAGO HELLERI. 



Perennial, robust. Foliage nearly glabrous : stems erect, 6- 

 16 dm. tall, usually green mottled with purple, branched above into 

 wide spreading panicles : leaves numerous ; blades narrowly elliptic 

 or oblong- elliptic, 3-10 cm. long, acute, serrate with appressed 

 teeth at least above the middle, smooth and glabrous above, spar- 

 ingly pubescent beneath, ciliate, sessile or nearly so above : racemes 

 one-sided, slightly recurved ; bracts linear or linear-spatulate : in- 

 volucres cylindric, about 6 mm. high, spirally twisted; bracts 

 glabrous, erect, firm, leathery, linear or linear-lanceolate, conspicu- 

 ously decurrent on the peduncle : rays 2-4, yellow, inconspicuous, 

 partly included ; blades oblong, 1-1.5 mm. long. 



In sandy woods, Arkansas. 



Solidago Helleri is related to Solidago rugosa and Solidaga idmi- 

 folia, possessing the general habit of the former and in the foliage 

 characters nearest to the latter. It differs from both relatives in 

 its peculiar heads ; these members are supported on slender pe- 

 duncles, which are often copiously furnished with delicate bracts. 

 These bracts grade into those of the involucre proper, and, like
