Solidago dumetorum sp. nov. 
Caules 5-10 dm. alti, dense et minutatim pubescentes vel 
scabri per totam superficiem, praecipue autem in parte superiore, 
striati, robusti, recti, valde foliosi. Folia firma, crassula, ad- 
modum tri-costata, ambobus lateribus scabra vel breviter pilosa, 
eoque magis in nervis strigosa, et per totam laminam inferiorem 
dense pubescentia, acuminata, lanceolata vel latiora, in parte 
dimidia marginis exteriore serrata, aspero-ciliata, media 1 dm. 
longa, 2 cm. lata. Capitula 4-5 mm. alta (vel magis), in paniculum 
amplum, pilosum conferta. Bracteae involucri late lineares vel 
deltoideae, zona viridi media exornatae. 
Stem 5-10 dm. high, closely and minutely pubescent through- 
out, the more so in the upper part, striate, stout, strict, very 
leafy. Leaves firm, thickish, strong’y triple-veined, scabrous or 
short-pilose on both sides, with a pubescence still more prominent 
on the veins, and rather close and appressed on the whole of the 
lower surface, taper-pointed, lanceolate or broader, serrate above 
the middle, rough-ciliate, the middle ones 1 dm. long, 2 cm. wide. 
Heads 4-5 mm. high, or more, crowded in an ample, pubescent 
panicle. Involucral bracts broadly linear or deltoid with a green 
zone in the middle. 
This plant belongs to the same group as S. elongata Nutt., 
which has nearly glabrous, sub-entire, obscurely 3-nerved leaves, 
an elongated panicle and linear-subulate involucral bracts, and 
S. Pitcheri Nutt., which has a stem glabrous up to the inflorescence, 
larger heads, and leaves more sharply serrate and glabrous except 
on the margins and on the mid-veins. The S. Pitcheri of this region
