Cystoseira hakodatensis (Yendo) Fensholt, 1952:563 ["hakotadense"].
PHILIPPINE DISTRIBUTION.—LEYTE (Leyte del Sur).
NOTE.—The name Cystophyllum J. Agardh (1848:228)
was superfluous when published inasmuch as the circumscription
of the genus included both of the original species
of Myagropsis Kutzing (1843a:57), the single original species
of Sirophysalis Kutzing (1843b:368), as well as several species
previously assigned to Sargassum C. Agardh (1820b: 1) and
Cystoseira C. Agardh (1820b:50). According to Article 7.11
of the ICBN, the type ofCystophyllum is the type ofMyagropsis,
the earlier of the two Kutzing generic names and therefore
the one that J. Agardh should have adopted. Fucus
myagroides Mertens ex Turner (1809:28, pi. 83) was designated
lectotype of Myagropsis by Silva (1952a:279) and is
thus the type of Cystophyllum. The lectotypification by De
Toni (1891:175), who chose C. trinode (Forsskal) J. Agardh
(1848:230), is irrelevant.
J. Agardh separated Cystophyllum from Cystoseira on the
basis of vesicle position. In Cystophyllum the vesicles were
said to be restricted to ultimate ramuli, while in Cystoseira
they are produced within the axes. The diagnostic value of
this character at the generic level was doubted by Gardner
(1917:390), who found both conditions in the same species.
Fensholt (1952) abandoned this distinction and treated as
members of Cystoseira most species that had been placed in
Cystophyllum by J. Agardh and subsequent authors. If Cystoseira
hakodatensis and other species currently placed in
Cystophyllum are segregated from Cystoseira, the segregate
genus cannot bear the name Cystophyllum, which, as shown
above, is a synonym of Myagropsis.

NOTE.—While returning most members of Cystophyllum
to Cystoseira, Fensholt (1952) retained the name Cystophyllum
for a new generic concept distinguished from Cystoseira
by a suite of developmental and cytological characters. Only
two species were known by Fensholt to share these characters,
namely, C. sisymbrioides (Turner) J. Agardh (1848:234)
and C. turneri Yendo (1907:40, pi. Ill: figs. 7-11). Upon
realizing that C. sisymbrioides included both of the original
species of Myagropsis, Fensholt (1955) adopted that generic
name for what she had previously designated Cystophyllum
J. Agardh emend. Fensholt. Papenfuss and Jensen (1967)
reviewed Fensholt's work and concluded that the segregation
of Myagropsis from Cystoseira was advantageous.
The conspecificity of Fucus myagroides and F. sisymbrioides
was proposed by J. Agardh (1848:234). Both species were
originally described in the second volume of Turner s
"Fuci.' If they had been published simultaneously, J.
Agardh would have been free to adopt either epithet in
preference to the other. Moreover, his choice (sisymbrioides)
would have been imposed on subsequent workers (Article
57.2). In fact, however, the two species were not published
simultaneously. Turner's "Fuci" was issued serially, with 12
parts constituting a volume (see Price, 1984). Although
