JAUMEA TENUIFOLIA (Sch. Bip.) Klatt, Leopoldina, xxiii. 146 (1887), 
p- 6 of reprint. Neurolaena tenuifolia Sch. Bip. acc. to Klatt, lL. e. 
This species, imperfectly characterized by Dr. Klatt, is shown by his 
fragments of type material to have rested upon a very immature 
specimen of some plant with pappus of capillary bristles and with the 
young corollas (still closed) purplish-tomentose. Though from the 
fragments at hand it is impossible to place the species in any genus, 
it may be said with perfect definiteness that the plant, with its fine 
capillary pappus, is not a Jawmea. Its habit is rather that of a Eupa- 
torium than of a Neurolaena, but the florets are too immature to 
furnish distinctive generic or even tribal characters. The type 
number (Liebmann, no. 202 from Chinantla, Mexico) is doubtless in 
other herbaria and may well be in some of them represented in sulll- 
ciently mature condition to permit more precise identification. In- 
formation on this subject would be welcomed. 
OxyPappus scaBER Benth. Bot. Sulph. 118, t. 42 (1844). There 
seems to be no doubt that Dr. Gray was entirely right in reducing to 
the synonymy of this species Pentachaeta gracilis Benth. in Hook. Ie. 
xii. 1, t. 1101 (1872), though the latter is maintained as a valid species 
by Hooker f. & Jackson in the Index Kewensis.

Dyssopia Cav. The various efforts which have been made to 
separate Hymenatherum Cass. from Dyssodia Cav. have proved so 
unsatisfactory that it seems best to follow Hoffmann in Engl. & 
Prantl, Nat. Pflanzenf. iv. Ab. 5, 265 (1890), and regard the distine- 
tions as being at best of subgeneric or sectional value. In accordance 
with this view, however, it is necessary to transfer several species, 9° 
follows:
