175. Viscum Henstovil, Hook. fil. ; foliosum, ramis dichotomis teretibus, foliis 
breviter petiolatis oblique ovato-lanceolatis subacutis basi subattenuatis 
5-nerviis opacis, spicis 6-8-articulatis folio 3 brevioribus: axillaribus ge- 
minis: terminalibus ternis, vaginulis bifidis acutis, floribus hexastichis.

Rami crassitie penne anserinze, teretes, hic illic articulati, internodiis 1-2-uncialibus; arti- 
culis vaginatis, ad axillas foliosis. Folia tripollicaria, valdé coriacea, 1} unc. lata, venis 
primariis 5 parallelis, pagina inferiore reticulatim venosá; petiolo 1-1} unc. longo, 
crassiusculo. Spice ad axillas foliorum 2-4, seepé terminales, erectz vel adscendentes, 
11-2 unc. longz, articulis supremis sterilibus. Bacce parve, sub 1 lin. diametro, 
globosz, semi-immersze. 
Very near the Viscum Perrottetii of Guiana, judging by the description in 
DeCandolle's * Prodromus'; the leaves are however smaller, the spikes with 
more articulations, and the principal nerves of the leaf can hardly be con- 
sidered as branched. In the specimens of this and the following species the 
branches are di- or rarely trichotomous, and the leaves only in the axils of the 
branches, never at the other articulations of the stem. "The flowers appear 
confined to the axils, and do not spring, as in some species, from other parts 
of the plant. 
176. Viscum GALAPAGEIUM, Hook. fil.; foliosum, ramis teretibus lignosis dicho- 
tomé divisis, foliis breviter petiolatis latè obovatis apice rotundatis valdé 
coriaceis aveniis, spicis axillaribus solitariis vel ad apices ramulorum ternis 
articulatis cylindraceis, floribus subhexastichis, ovariis semi-immersis. 
Hab. Chatham Island, Charles Darwin, Esq. 
Priori affine, sed foliorum aveniorum forma distinctum. Rami crassitie pennz anserinz, 
internodiis 3-uncialibus. Folia 2 unc. longa, subsessilia v. petiolo brevi instructa. 
Spicz £ unciales multiarticulatz, ad articulos vaginate ; vaginis breviter bifidis.
