RECORDS OF TRENTEPOHLIEAE
FRONIPAPUA I.

SUMMARY
The following species of Trentepohlia arc newly recorded from Papua: T. aUJ"Ca (L.) Martius"
1'. atborum, (C.Ag.) Hariot, T. cuC'ullala de Wild., T. treubiana de Wild., T. odorata (Wigg.)
Wittr., T. effusa (Kremp.) I-briot, T. diJrusa de Wild ..
During December 1955 and January 1956 the author collected specLmens
of the algal group Trente1)ohlieae from the Tcrritory of Papua at Aird Hill in
the delta of the Kikori River, and at Ubuia and Normanby Islands in the
D'Entrecastcaux group. The collections were made at heights not over 500 ft.
above sea level, and it may be expected that collections from considerably higher
altitudes will increase the number of species known from the Territory. Two
species, T. elli1)siocarpa Schmidle and T. minima Schmidle are previously recorded
for the island of which the Territory of Papua forms a part.
Trentepohlia wurea (L.) Martius
Cribb, 1958, p. 194. pI. I, fig. 8-10.
'rwo collections from Ubuia agree well with Queensland plants assigned to
this species. A third specimen, from Aird Hill, differs in having filaments gener-
ally a little broader, to 30 p. diam., and the cells generally proportionally a little
shorter, B-3 diam. long. It lacks the somewhat silken sheen of the other speci-
mens referred to T. aUl'ea, and differs further in having terminal pedicellate
sporangia. Nevertheless, it seems best placed in T. wurea which is known to be
a very polymorphic species with numerous varieties and forms.
Hab.: On rocks in shaded position, Ubuia; on tree trunk in light rainforest,
Aird Hill.
Trentepohlia bossei de Wildeman
Cribb, 1958, p. 194, pI. I, fig. 1-7.
The material agrees well with specimens from Queensland and shows the
peculiar branching from the supporting cell of a sporangium which apparently
characterises this species.
Hab.: On tree trunks and rocks mainly in light rainforest and in coconut
plantation, Aird Hill, Ubuia, Normanby Is.
T)~ntepohlia arborum (C.Ag.) Hariot
Hariot 1889, p. 383, fig. 8-9; 1890, p. 1')3. Printz 1939, p. 151, pI. 6, fig. A.H.
This species is readily recognised by the usual grouping of several pedicellate
sporangia on the swollen terminal cell of the tapering filament.
H ab ..: On tree .trunk.s, and formin§? wefts of filaments to. 1 em. long on the
leaf margms of several ramforest f10wenng plants and ferns, Alrd I-Iill.
204 A. B. CRIBB
Tre·ntepohlia cttotllata de 'Wildeman Fig. 1.
Printz 1939, p. 149, pI. 4, fig. B-D.
In cell size and proportions this species resembles T. bo.r.rei, but is readily
distinguished by the characteristic smooth, brown, hemispherical caps on apical
cells and sporangia.
H ab.: On tree trunk in light rainforest, Aird Hill.
Trentepohlia treubiana de Wildeman Fig. 2-6.
Printz 1939, p. 148, pI. 2, fig. B-F.
This small species with usually non-tapering filaments 5-10 It in diam.,
possesses both terminal and intercalary sporangia, the latter occurring singly or
in short series.
H ab.: On tree trunk in light rainforest, Aird Hill.
Trentepohlia odorata (Wiggers) Wittrock
Cribb 1958, p. 194, pI. 2, fig. 1-9.
H ab.: Forming an orange-red pulverulent stratum on a hardwood fence,
Aird Hill.
Trentepohlia effu.ra (Kremp.) I-lariot
Cribb, 1958, p. 196, pI. 4, fig. 1-6.
Hab.: On tree trunks and on leaves, particularlv on the hairs of a fern frond.
in rainforest, Aird l-lill.· - .
Trentepohlia diffuJa de Wildeman Fig. 7··8.
De Wildeman 1888, p. 182; Hariot 1890, p. 51, fig. 19; 1890, p. 196; Printz 1939, p. 166,
pI. 14, fig. G-J.
. This very distinctive species has a prostrate axis of which each cell fre-
quently gives rise on the dorsal surface to a simple, erect, tapering branch, and
on each lateral face to a short prostrate basically 3-partite branch system' the
prostrate system thus possesses a distinctly pinnate appearance. An erect b/anch
may also arise in many cases from the basal cell of each 3-partite branch system.
The prostrate systems may be widely scattered or closely associated so that
a low felty colony up to 2 em. diam. may be formed on the surface of the leaf.
Length of the erect filaments varies considerably between different collections,
being 300-2000 It long.
Hab.: On tree trunk or more usually on leaves, in light rainforest, sometimes
on Rhizophora leaves submerged during spring tides, Aird Hill.
