lithographer responsible for Montagne's
illustration (Pl.2), It reads: "Laminaire a
dessiner, autant que possible, de grandeur naturelle
Cet echantillon m'appartient; i1 a ete happorte
par M. Gaudichaud des iles maloilline et n'avait
pas ete compris pa:cmi les cryptogames du second
voyage. tvi D' arbigny en ayant rapporb~ des
laminaires identigues avec celles de cet:te nouvelle
e spece, j e pens e go' :\,1 conv ien-t de la publier dans
son ouvrage." Montagne's illustration is of a
cornplete pla.nt vJith. a large palm. The distal
third of the lamina is split into several narr01lf
thongs. The herbarium specimen described above,
IIIhich consists of a holdfast, stipe, the basal
part of the lamina and part of a 'chong could very
well be the same plant. Montagne also stated that
the specimen illustrated in Plate 2 had been
collected by Gaudichaud, and this agrees ,\Ii th the
information on the label,
Areschoug (1854) recognised L. eaepaestipes as a synonym of
D. utilis Bory. Delepine (1964:142, PI.LA) sectioned the lamina of
the above specimen and found that it contains honeycomb tissue, a
feature characteristic of D. a1'lta:retiea. Areschou.g (185.il: 16 [342} }
stated that L. caepaestipes Mont. was the same as several specimens
in the sample of 50 preserved D. utilis plants from the Falkland
Islands that he has examined.
Skottsberg (1907: 142) claimed tha-t L. caepaestipes ~)as
the scune
as D. harveyi Hook. fil. (described la'cer) r ;;>ncl that t.he Montagne's
epithet took priority. In 1921 he stated t.hat L. caepaestipes \"as
an intermediate form closer to D. haY'veyi than D, an tarcn':;ica. Naylol::
(1954) regarded D. harveyi and D. caepe8 t-ipes as synonyms.
There are no reasons why D. caepeBtipes (Mont. ) Skottsbg.
should be regarded as an entity scpa:r.ate from D. ol1tapct.,:cQ,
