2022), Morne Anglais (DeFilipps 181, Hodge 2258), Mome
Micotrin (Hodge 2096), sine loc. (Zmruy 425 at K, 281 at
GOET).
Similar to Phorudendron mucronutum but leaves smaller
and localities much higher.
Zmruy 281 is a type of this variety. Kuijt (196156) was
dissatisfied with the groupings in D. ellipticu and provisionally
left it without infraspecific taxa. Kuijt’s (196153) citation of
Imrq 425 from “Hispaniola, Dom. Rep.” involves confusing
Dominica with the Dominican Republic.
Kellogg (in Howard, 1988, 4:103) called this taxon
Dendrophfhoru buxifoliu (Lamarck) Eichler. It is not clear why
she thought that Kuijt claimed that the species (0. ellipticu)
occurred only in South America, because he cited Dominican
(Imray) material.
Phoradendron Nuttall
The inflorescence has fertile internodes separated by a pair of
bracts. Several arrangements of flowers are found on fertile
internodes, the basic ones being tetrastichous with two parallel
columns with an apical flower between the columns above each
bract (called type la by Kellogg and Howard, 1986) and
hexastichous with three parallel columns above each bract
(called type lb). When more than 6 flowers are found above
each bract the two basic types are easier to recognize but when
only 3-6 flowers are found above each bract the basic “types”
are become unclear and Kellogg and Howard (1986) recognized
three in the Antilles: 3-flowered triad (the apical one
staminate), 4-flowered (type Id), and 6-flowered (type le), the
latter 2 (like lb) with a basal flower. Rarely only 1 flower is
found per bract (P. trinervium).

The Imray collection was misidentified as Phorudendron
murtinicense by Grisebach (1860:314), according to Trelease
(1916:198), who identified it as P. chrysocarpum.
