ceous Jobe, similar to what takes place (except in respect of co- 
lour) in the well-known Mussenda of our stoves. It is a plant, 
too, interesting in another point of view, as one of a new ge- 
nus of which the typical species, Howardia febrifuga, Weddell, 
of Bolivia, has been detected as one of the medicinal barks of 
commerce, and much used by the Bolivians in intermittent 
fevers.* To this plant Dr. Weddell has assigned the generic name 
Howardia. “Parmi les genres,” says Dr. Weddell, “que jai 
fait connaitre dans ma Monographie des Quinquinas, il en est un 
auquel jappliquai, par mégarde, un nom (Chrysoxylon) apparte- 
nant a une plante d’une autre famille. Pour mettre fin 4 ce double 
emploi, je vais aujourd’hui donner 4 ma Rubiacée un nom nou- 
veau ; et je ne fais, ce me semble, qu’un acte de justice en lais- 
sant tomber mon choix sur celui de l’excellent quinologiste qui 
vient de publier, en Angleterre, un mémoire aussi judicieux 
qu approfondi, sur la collection de Quinquinas de José Pavon, 
léguée par Lambert au Musée Britannique.” No compliment 
could be better deserved. Another described plant referred to 
this genus by M. Weddell is the Calycophyllum tubulosum of 
De Candolle, from Brazil. A third species is the Howardia 
grandiflora, Weddell, readily distinguished by its linear calycine 
teeth; and a fourth species is the Howardia Caracasensis, cer- 
tainly our plant of Venezuela, but so nearly allied to Howardia 
tubulosa that Dr. Seemann has united the two, as well as a 
Peruvian species in my herbaria, which latter, I think, will prove 
different. : 
Howardia Caracasensis, as its name implies, is a native of the 
province of Caracas, in Venezucla, where it was detected by 
FPuncke (P\. Exsice. n. 463, in Herb. Paris., n. 372, Herb. Hook.). 
We possess specimens also from Fender, from the shme country, 
and from our collector, 47. Birschell, and from the banks of the 
river Chagres, in Panama, gathered by Seemann.
