nate the branches, have been seen on the large plants 
cultivated at Philadelphia as much as twenty inches across, 
and equal in colour to the finest tints of Hrerscus Rosa- 
sinensis. The structure seems to me to constitute a new 
generic type, though in several species of Evrpnorsta, as in 
E. splendens, there are the rudiments of the remarkable septe 
found in the involucre here. I have dedicated it, if not to 
its original discoverer, at least to one who has first brought it 
into cultivation, and into general notice among Botanists, 
and from whose exertions many additions to the plants in 
cultivation from Mexico are expected. The period of flow- 
ering both at Philadelphia and here seems to be in winter, 
or early in spring. I entirely agree with Sir W. J. Hooker | 
that Eupvorsia cyathophora, Bot. Reg. t. 765, will be found 
to be a member of the same Genus. 
_. Descr. Shrué erect, ramous; branches round, yeung shoots bluntly 
four-angled, green, glabrous, hollow. Leaves scattered, occasionally 
opposite, spreading; petiolate, ovato-elliptical, subacute, sinuated, vein- 
ed, soft and pubescent on both sides, bright green above, paler below. 
- Petioles furrowed above. Bractee similar in shape to the leaves, but 
aggregated at the extremities of the branches, and of splendid vermilion 
colour, paler below. Cymes terminal, subtrifid, at length falling off at a 
joint in the common foot-stalk. Jnvolucres on short, stout foot-stalks, 
articulated at the base, green, ovato-orbicular, toothed, marked by five 
sutures on the outside, with which alternate, on the inside, five faleate 
rocesses, beginning with narrow extremities at the mouth of the invo- 
ucre, and, adhering to this with their backs, they become gradually | 
broader below, passing inwards, and attached to an elevation in. the

and supporting on their edges erect fimbrie, they divide the upper part 
which are next each other in the
