1. Hedera arborea ; foliis simplicibus late ovalibus basi apice rotundatis vel ovatis 
acuminatis, floribus umbellatis, umbellis racemosis superioribusve subumbellatis longe 
pedunculatis, pedunculis patentibus vel deflexis, stylis in unicum pentagonum conicum 
coadunatis. — H. arborea. Sw. ? De Cand. ? Prod. 4. p. 262 ? 
Petala quinque, libera, calycis margo quinquecrenatus. 
Of this order we find two other species in the collection, both without leaves. The one is from Talisco, 
and has the flowers capitate, the capitula peduncled and disposed in a raceme, as in many species o^ Actino- 
phjllum and Hedera, but has only two styles, as in Panax, to the known species of which it has little 
resemblance. In the other, from Topic, the flowers are umbellate, from fifteen to thirty in each umbel : these 
umbels form a corymbose pannicle, the branches of which are covered with a mealy pubescence that is easily 
rubbed off ; there are five styles, which are united into one to near the middle, the upper portion being 
recurved. This is perhaps Aralia pubescens.

1 . Loranthus calyculatus. De Cand. ? 
The structure of the flowers and bractea is the same with the plant of De Candolle, but the young branches 
are angled : we should have supposed it to be L. Scheidianus, Schlecht. (in Linnsea, 5. p. 172), so well does 
it generally agree with the description, but that has a corolla three inches long, while in ours it does not 
exceed half that length. The leaves are ovate-lanceolate, falcate, and acuminated. 
In the collection there is another species of Loranthus, or perhaps of Viscum, with opposite, oval, acute, or 
obtuse leaves, and long slender branches, but there is neither flowers nor fruit.
