rymbosis polycephalis, acheniis hispidulis, pappo simplici 
coroniformi fimbriato stellato-patente.— Sierra Leone, Don; 
Fernando Po, Vogel. 
Herba ramosissima, diffusa, habitu et inflorescentia formis de- 
eumbentibus Vernonie cineree subsimilis. Pubes ferru- 
ginea, in ramulis novellis sublanosa, demum parca, in foliorum 
pagina superiore rara v. nulla. Folia petiolata, ovata, 1-13- 
pollicaria, integra v. sinuato-dentata, membranacea, ramealia 
minora interdum obovata, samma parva, oblonga. Corymbi 
laxi, irregulares, foliis paucis parvis bracteati. Capitula quam 
in Ethulia minora. nvolucri squamxe subbiseriales, lineari- 
oblongz, acute, virides, puberule ; adjectis nonnullis exte- 
rioribus minoribus setaceis. Receptaculum planum, nudum. 
Flores im capitulo circa 20, homogami, involucro paullo 
longiores, violacei. Corolla tubuloso-campanulata, superne 
pilosiuscula, basi attenuata, laciniis 5 tubo sequilongis, apice 
extus glandulosis. Anthere lineares, ecaudate. Styli lobi 
subulati, recurvi, acutiuseuli. Achenia $ lin. longa, obscure 
angulata, undique hispidula. Pappus albus, stellato-patens, 
constans e paleis brevissimis fimbriato-multifidis ; setis €x- 
terioribus nullis. : 
This plant has more the habit of E/Aulia than of Herderia 
truncata, but differs from the former genus in the involucre, 
achenia and pappus. The pappus has the scales shorter than 
in Herderia truncata, and there is either no trace at all of outer 
sete, or they are so short and slender as to be scarcely per- 
ceptible. Perhaps the two genera, Ethulia and Herderia, ought 
to be united. 
The original Herderia truncata appears to be confined to 
Senegal, whence I have what I believe to be a third specie» 
gathered by Michelin.
