MR. D. OLIVER ON THE LORANTHACE E. 93 
cosus the anthers in bud resemble those of Viscum; but they are 
free, and I doubt if the dehiscence be by pores as in that genus. 
The stellate pubescence of this Ceylon plant is similar to that of 
two of the Australian species. 
ARCEUTHOBIUM, Bieberst. 
The bifid perianth of the 9 flowers, which are terminal, or 
opposite in the axils of the sheaths, distinguishes this genus from 
Phoradendron. J cannot agree with Prof. Grisebach in referring 
to Arceuthobium the West-Indian species described in his ‘Flora 
of the British West Indies’ (p. 815). They appear to me un- 
doubtedly aphyllous species of Phoradendron. 
PHORADENDRON, Nutt. 
I have not undertaken to arrange subdivisions of this large 
genus; they will form an interesting study for the botanist who 
may have to elaborate the Loranthacee of the ‘ Flora Brasiliensis.’ 
The leaves are wanting, or reduced to squame, in but few species. 
The anthers are described as two-celled ; and so they usually are in 
some species, for example in Ph. flavescens of the United States; 
but in others they are certainly one-celled, probably by confluence 
of the pores or slits of dehiscence. Indeed, in Ph. flavescens Y 
have found the anthers occasionally thus one-celled. I have there- 
fore modified the diagnosis in this regard. The species with one- 
celled anthers, referred to Arceuthobium by Dr. Grisebach in his 
‘Flora of the British West Indies,’ appear to me to belong pro- 
perly to Phoradendron. His Ph. buxifolium (Pl. Cubenses, 220) 
and Ph. serpyllifolium (Wright, Pl. Cub. no. 1254) have certainly 
one-celled anthers. A few leafless or nearly leafless species much 
resemble Arceuthobium at first sight, especially those which have 
the floriferous internodes excessively short and only two-flowered, 
the flowers being almost or quite in the axils of the sheaths. The 
flowers are, however, more or less immersed in the rachis, and have 
three-lobed perianths. The Castrea falcata alluded to by St. Hilaire 
(Lecons, p. 451, and fig. 335) I presume must be a Phoradendron. 
ANTIDAPHNE, Poeppig. 
To this imperfectly described genus I refer a Venezuelan plant 
with 9 flowers collected by Fendler, and another ( d ) by Seemann 
in Veraguas. I feel no doubt these belong here, having a Peruvian 
specimen of the original A. viscoidea in the Hookerian herbarium, 
besides Poeppig’s rather imperfect figure of it, to guide me. The
