de purgar than many other species of Cassia. The flowers of C. Fistula, L., are of light 
yellow and in very long racemes, and the leaflets are different in shape and much larger. — 
The flowers of the Cañafistola de purgar are yellow, becoming brick-red with age; the 
racemes are much shorter than those of Cassia Fistula; and the leaflets are altogether 
different, being much smaller and quite like those of C. brasiliana; in fact, the Caña- 
fistola de purgar is much nearer C. brasiliana than it is to C. Fistula. The wood of the 
tree is very dark-coloured, heavy, and compact, and is considered one of the best on the 
Isthmus: it makes excellent fuel. The tree is very common in open woods on hills, and 
is perfectly indigenous; whereas C. Fistula is to be found only about towns and in old 
cleared places, as if introduced. I have never seen C. Fistula in the virgin forests. 
C. brasiliana is very common about Panama." 
Upon examining Mr. Hayes's plant and comparing it with the species of Cassia already 
described, I have found it to agree with the Cassia moschata of Humboldt, Bonpland, 
and Kunth, so far as the characters of that plant have been recorded; and M. Triana, 
who is now engaged on the Flora of New Granada, and has compared Mr. Hayes's 
specimens with the type specimens in Paris, has arrived at the same conclusion. As the 
notiees of this plant hitherto published are quoted entirely from the * Nova Genera et 
Species, the authors of which had not seen the flowers, I have thought it desirable to 
draw up a complete description, which, with a drawing, I have now the honour of laying 
before the Society.
